Persistent joint pain that does not improve with rest should never be ignored—especially when it affects your hip, knee, or shoulder. Many people assume it is just muscle pain, arthritis, or age-related discomfort, but sometimes the real cause is something more serious called Avascular Necrosis (AVN). AVN is a condition where the blood supply to the bone gets reduced or blocked, causing bone tissue to die gradually. If not treated early, it can lead to severe joint damage and may even require joint replacement surgery. The good news is that early diagnosis and timely treatment can help preserve the joint and prevent major surgery. At Dr. Vinayak Ghanate’s clinic in Baner, Pune, patients receive advanced orthopedic care for AVN, joint preservation, hip pain, trauma, sports injuries, and complex orthopedic reconstruction. What is Avascular Necrosis (AVN)? Avascular Necrosis, also known as Osteonecrosis, is a condition where the blood flow to a bone is interrupted. Without proper blood supply, the bone tissue starts dying, leading to: AVN most commonly affects: The hip is the most frequently affected joint, especially in adults between 30 and 50 years of age. Early Symptoms of AVN In the early stages, AVN may not cause obvious symptoms, which is why many patients ignore it. As the condition progresses, common symptoms include: 1. Deep Joint Pain Pain usually starts deep inside the joint, especially in the hip or groin area. Patients often describe it as: 2. Hip Pain While Walking If the hip is affected, pain may spread to: Many people think it is simple muscle pain and delay treatment. 3. Reduced Range of Motion You may notice: This happens as the joint surface becomes damaged. 4. Limping While Walking As pain worsens, patients often start limping to reduce pressure on the affected side. This is a strong sign that specialist evaluation is needed. 5. Pain Even During Rest In advanced AVN, pain may continue even while: This indicates progression of bone damage. Common Causes of Avascular Necrosis Several factors can reduce blood supply to the bone. 1. Long-Term Steroid Use Prolonged use of corticosteroids is one of the most common causes of AVN. This may happen in patients treated for: 2. Alcohol Consumption Heavy alcohol intake can affect fat metabolism and blood circulation, reducing blood supply to bones. 3. Trauma or Injury Fractures, hip dislocation, or severe injuries can damage the blood vessels supplying the bone. This is called post-traumatic AVN. 4. Medical Conditions Certain diseases increase AVN risk: 5. Unknown Causes In some patients, AVN develops without any clear reason. This is called idiopathic AVN. When Should You See an Orthopedic Surgeon? You should consult an orthopedic specialist if: Early diagnosis is the best way to avoid joint collapse. How AVN is Diagnosed At Dr. Vinayak Ghanate’s clinic, diagnosis begins with a detailed orthopedic evaluation. Further tests may include: MRI is often the best test to diagnose AVN in its earliest stage. Best Treatment Options for AVN in Pune Treatment depends on how early the condition is diagnosed. Non-Surgical Treatment (Early Stages) If AVN is detected early, joint preservation may be possible through: Early treatment can delay or even prevent joint replacement. Surgical Treatment (Advanced Stages) If the bone has already collapsed, surgery may be required. Treatment options include: The right approach depends on the stage of AVN. Why Choose Dr. Vinayak Ghanate for AVN Treatment in Pune? Dr. Vinayak Ghanate is known for advanced orthopedic care and precision-driven treatment planning. His expertise includes: His international training includes: Patients trust him for his honest consultation, precise diagnosis, and personalized treatment approach. Can AVN Be Cured Without Surgery? Yes, if diagnosed early. In Stage 1 or Stage 2 AVN, non-surgical or joint-preserving procedures can often prevent progression. But once the joint surface collapses, surgery usually becomes necessary. This is why early consultation is extremely important. Final Thoughts Avascular Necrosis is a serious condition, but it does not always mean immediate surgery. The earlier it is diagnosed, the better the chances of saving the joint. If you are experiencing unexplained hip pain, limping, groin pain, or difficulty walking, do not delay specialist evaluation. Timely treatment can protect your mobility, independence, and quality of life.

Take the first step toward pain-free movement and better joint health.

Let’s Be Honest: “Robotic Surgery” Sounds Like a Buzzword When patients hear the words robotic knee replacement surgery, one of two reactions is almost guaranteed. Either their eyes light up because it sounds cutting-edge and reassuring or they get suspicious, wondering if it’s just a marketing gimmick designed to charge more. Both reactions are understandable. And as a surgeon who has trained and operated across leading institutions in India and the United Kingdom, I believe patients deserve a straight answer not a sales pitch. So here it is: robotic knee replacement surgery is not a gimmick. But it’s also not a magic solution for everyone. What it is, when used correctly and by a trained surgeon, is one of the most meaningful advances in joint replacement surgery of the last two decades. Let me explain exactly why and help you figure out if it’s the right choice for you. What Is Robotic Knee Replacement Surgery, Really? To be clear: a robot is not performing your surgery. You are not being operated on by a machine. The surgeon is in complete control at every moment. What robotic-assisted knee replacement actually involves is a sophisticated, real-time surgical guidance system that works alongside the surgeon. Before the procedure, advanced imaging is used to create a precise, three-dimensional digital model of your knee your specific bone geometry, alignment, and joint anatomy. Not a generic template. Yours. During surgery, the robotic arm provides real-time feedback and boundary controls, allowing the surgeon to prepare the bone surfaces with an accuracy that goes beyond what the human hand can consistently achieve with traditional instruments alone. Every cut, every angle, every millimeter of implant positioning is guided by patient-specific data. The result is a knee replacement that is calibrated to your anatomy not just placed according to general guidelines. Why Precision Matters So Much in Knee Replacement Here is something many patients don’t realize: the long-term success of a knee replacement depends enormously on implant alignment and ligament balance. An implant placed even a few degrees off can cause accelerated wear, persistent pain, stiffness, or instability sometimes requiring a revision surgery years down the line. Traditional knee replacement relies on mechanical jigs and the surgeon’s trained eye. In highly experienced hands, this works very well. But robotic assistance adds an extra layer of consistency, especially in complex cases or patients with unusual anatomy. Studies in peer-reviewed orthopedic literature consistently show that robotic-assisted knee replacement delivers more accurate implant positioning compared to conventional techniques. Better alignment translates to more natural knee movement, less post-operative pain, faster rehabilitation, and longer implant life. For patients seeking the best robotic knee replacement in Pune, this precision advantage is the core reason surgeons and patients alike are choosing this approach. What Are the Real Benefits of Robotic Knee Replacement? Let’s be specific. Here is what the evidence and clinical experience show: 1. Superior implant alignment: The robotic system guides bone preparation within sub-millimeter accuracy, reducing the risk of malalignment a leading cause of long-term knee replacement failure. 2. Personalized surgical planning: Unlike traditional surgery that follows standard measurements, robotic systems create a procedure plan based on CT scan data of your actual knee. The surgery is tailored to you. 3. Less bone removal: Robotic guidance allows surgeons to preserve more healthy bone while removing only what is necessary important for future revisions if ever needed. 4. Faster recovery, reduced pain: Patients undergoing robotic knee replacement often report less post-operative swelling and pain compared to conventional surgery, allowing physiotherapy to begin sooner. 5. Greater confidence in outcomes: For patients with complex anatomy, previous injuries, or deformity, robotic assistance helps surgeons navigate challenges that would otherwise carry higher risk. 6. Longer implant longevity: Optimal alignment and balanced soft tissue tension reduce wear on the implant surfaces potentially extending the functional life of the prosthesis well beyond the standard 15–20 years. Is Robotic Knee Replacement Right for You? Robotic-assisted surgery is an excellent option for most patients requiring knee replacement but your suitability depends on a clinical evaluation. It is particularly beneficial for: It is worth noting that the robotic system is a tool its value depends entirely on the surgeon using it. A highly trained surgeon with experience in robotic-assisted technique will deliver significantly better outcomes than one learning the system on the job. This is why choosing the right surgeon matters as much as choosing the right technology. What About the Cost? Robotic knee replacement surgery typically costs more than conventional knee replacement. This is a real consideration and one worth addressing directly. The additional cost accounts for the technology platform, the patient-specific preoperative imaging and planning, and the time investment in robotic-guided execution. For most patients, when weighed against the benefits of improved precision, faster recovery, and potentially longer implant life the value is clear. Revision surgery, should it ever become necessary due to malalignment, is significantly more complex and expensive than getting the first surgery right. That said, cost varies by hospital, implant type, and individual case complexity. A consultation with your surgeon will give you an accurate picture of what to expect for your specific situation.

There may be more than just the usual mechanical or age-related components of the body causing joint discomfort, which are often written off as a sign of weariness, aging, or excessive stress. Sometimes, rest or other simple steps might help reduce joint pain, but other times, an underlying inflammatory disease (like rheumatoid arthritis) could be the cause of the pain in the joints. Early detection of rheumatoid arthritis symptoms can improve treatment outcomes and help avoid long-term impairments and disabilities brought on by this inflammatory condition. When a person has an autoimmune condition, their immune system targets the tissue lining their joints. In contrast to normal wear-and-tear joint issues, rheumatoid arthritis can cause discomfort in many joints at once and, if left untreated, can deteriorate rapidly. By looking at which joints are impacted, a person might spot potential indicators that they could have rheumatoid arthritis. 1. Morning stiffness lasting more than an hour One of the classic symptoms of rheumatoid arthritis is increasing morning stiffness. For example, a person might get milder morning stiffness, but if the stiffness lasts longer than 60 minutes and goes away with exercise, it could indicate inflammation in the person’s joint or joints. 2. Multiple Joint Pain Rheumatoid arthritis will cause pain in two or more joints at the same time, although other types of arthritis only cause pain in one joint and usually appear days after an injury or separation. In the early phases of rheumatoid arthritis, the most afflicted minor joints are those in the hands, wrists, and feet. 3. Bilateral joint involvement If a person experiences pain or swelling in one or more joints and also has pain or swelling in the same joint or joints on the opposite side, they should rule out overuse and suspect an underlying inflammatory condition. 4. Inflamed joints: Warmth and swelling Swelling and soreness to the touch are common symptoms of inflammatory joints, which can also occasionally feel warm to the touch. While swelling brought on by too much fluid in or around the joint is common, inflammation of the joint’s lining can also result in swelling; if left untreated, this can cause gradual damage to the bone and cartilage. 5. Constant exhaustion and poor vitality It’s possible that rheumatoid arthritis affects more than simply the joints. A widespread feeling of exhaustion, poor energy, and/or illness is a common complaint among RA patients. The consequences of inflammation throughout the body might cause the “unwell” sensation to appear before serious joint pain does. 6. Having trouble with basic hand tasks In the early stages of RA, simple actions like buttoning clothes, twisting a doorknob, or opening a jar can be difficult. Usually, the first functional limitation identified is the inability to squeeze firmly because of a weak grasp or soreness in the fingers. 7. Weeks of pain Do not disregard joint discomfort if it lasts for a long time (at least a few weeks) and is accompanied by stiffness, edema, or both. Temporary pain will go away in a few days, but rheumatoid arthritis that is left untreated will often not get better and can become worse over time. Early diagnosis is important for the management of rheumatoid arthritis. Physical examinations, imaging studies, and blood tests can all aid in the disease’s diagnosis. Medication to lower inflammation and stop more joint deterioration, together with physical therapy to maintain mobility, is the primary treatment for RA. At this stage of the condition, surgery usually is not required; however, if a joint is badly injured, operations such a synoviectomy, which removes the synovial lining, or joint replacement may help restore function and alleviate pain. Modern surgical methods and rehabilitation programs have greatly improved the results for individuals undergoing these operations. Along with the tangible signs of the condition, patients often struggle with mental anguish because of their chronic pain, decreased activity levels, and need for assistance to do daily tasks. This emotional anguish can impact a patient’s quality of life and general feeling of well-being (such as despair, anxiety, and self-confidence). Following the prescribed treatment plan, getting prompt medical care, and having family support may all help a patient live a happy and productive life. It is not appropriate to accept joint pain as a normal aspect of life, particularly if it starts to interfere with day-to-day activities or persists over time. A patient can delay the disease’s progression and extend the preservation of his or her joints for many years to come by recognizing the early warning signs of RA and obtaining timely medical attention.

The COVID-19 pandemic has brought many unexpected health complications, and one such alarming consequence is Avascular Necrosis (AVN) of the hip. AVN, also known as osteonecrosis, is a condition where blood supply to the femoral head (the ball of the hip joint) is disrupted, leading to bone death and eventual joint collapse. While AVN has been previously linked to steroid use, trauma, and alcohol consumption, emerging studies suggest that COVID-19 may be a significant contributing factor. Understanding AVN and Its Connection to COVID-19 AVN occurs when the blood supply to the bone is compromised, leading to the gradual death of bone tissue. The exact mechanisms by which COVID-19 contributes to AVN are still being explored, but some possible explanations include: Symptoms of AVN of the Hip Early detection of AVN is crucial to prevent severe joint damage. Common symptoms include: Diagnosis and Treatment Options If you have a history of COVID-19 and experience persistent hip pain, consult a doctor for evaluation. Diagnosis typically involves: Treatment Approaches The treatment of AVN depends on the stage of the disease: Preventing AVN After COVID-19 While not all cases of AVN can be prevented, some proactive measures include: In conclusion– Avascular Necrosis of the hip is a serious but often overlooked complication following COVID-19. Awareness, early detection, and timely intervention are key to preventing long-term disability. If you or someone you know is experiencing persistent hip pain after COVID-19, seeking medical evaluation promptly can make a significant difference in treatment outcomes.

HIP REPLACEMENT​ “Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi replacement”. THE HIP JOINT – The hip joint is ball and socket joint. The thigh bone has a round head (Ball) which fits in saucer shaped socket (Acetabulum) in Pelvic bone. The surface of the head of the thigh bone and the socket are covered by specialised tissue called articular cartilage. The joint cavity is lined by a membrane called the synovium which secretes synovial fluid into the joint and allows smooth movement of the ball within the socket. Choosing the right Implant – The doctor will decide about the best material to be used in your case. This selection will depend upon factors such as – You’re age. Normal level of Activity Degree of damage Arthritis of your Hip Joint Although a replaced hip joint may continue to function successfully for 15-20 yrs or more, it will not last forever. Careful consideration is therefore necessary before replacing the hip of someone in their forties or fifties, as they are likely to require revision surgery in future. In such conditions cementless prosthesis may be most appropriate. Femoral Component: Femoral component prosthesis replaces the head of the femur. It contains ball shaped head & a stem which is fixed into the shaft of femur. Femoral component is made of a variety of metals. Stem: Stem is fixed in Thigh bone It can be – Cemented or Uncemented Stem Head: Head is fixed on the stem. It is made of any one of the following metals. Cobalt Chrome, Zirconium, Ceramic Acetabular Component: It is fixed to the socket. It can be- Uncemented, Cemented Who is offered hip replacement surgery? You may be offered hip replacement surgery if: You have severe pain, Swelling and Stiffness in your hip joint and your mobility is reduced. Your hip pain is so severe that it interferes with your quality of life and sleep. Everyday tasks, such as shopping or getting out of the bath, are difficult or impossible. You’re feeling depressed because of the pain and lack of mobility. You cannot work or have a social life. How the operation is done – Hip replacement surgery is usually done either under general anaesthetic (you’re asleep throughout the procedure) or under spinal anaesthetic (you’re awake but have no feeling from the waist down). Sometimes you may have an epidural, which is similar to a spinal anaesthetic. Once you’ve been anaesthetised, the surgeon makes a cut (incision) on the side of your hip. The upper part of your thigh bone (femur) is removed and the natural socket for the head of your femur is hollowed out. A socket is fitted into the hollow in your pelvis. A short, angled metal shaft (the stem) with a smooth ball on its upper end (to fit into the socket) is placed into the hollow of your femur. The cup and the stem may be pressed into place or fixed with bone “cement”. The operation takes up to 1-2 hours. POSSIBLE RISKS – As with any operation, hip replacement surgery has risks as well as benefits. Most people who have a hip replacement do not have serious complications. After having a hip replacement, contact your doctor if you get: Hot, Reddened, Hard or Painful areas in your leg in the first few weeks after your operation. Although this may just be bruising from the surgery, it could mean you have DVT (deep vein thrombosis) – a blood clot in the leg. Chest pains or Breathlessness- Although it’s very rare, you could have a blood clot in your lung (pulmonary embolism) which needs urgent treatment. To reduce your risk of blood clots, you’ll be given blood-thinning medicine and compression stockings. Moving your legs as soon as you can after the operation is one of the best ways to prevent blood clots. Check with a physiotherapist what you should be doing. Hip Dislocation– In a small number of cases the hip joint can come out of its socket. This is most likely to happen in the first few months after surgery when the hip is still healing. Altered leg length – The leg that was operated on may be shorter or longer than the other leg. People can adjust to this, but sometimes a raised shoe may be needed. Infection – Hip replacement surgery is done in an ultra-clean operating theatre and antibiotics are given during the operation. But in less than 1 in every 100 operations, an infection may still happen. Very rarely, the hip replacement may need to be “washed out” or a new replacement may be used. It’s normal for the wound to be slightly red and warm to touch while healing. However, if you feel unwell, the pain is getting worse or the wound starts to leak fluid, contact the specialist. Before the Surgery – After your decision to go in for a joint replacement you should be aware of the basic things to be done before surgery. Such as – Suitable prosthesis for you. The cost of your prosthesis. Total Hospital stay & cost of hospital stay. The Blood, Heart and Chest investigations. Get these investigations 1 week before the date of surgery & get them checked by a physician. It is necessary to confirm that there is no active infection in your body. If you have medical insurance, you should contact hospital’s Billing and Insurance Desk at least one week before surgery with your policy documents. You should show the drugs which you are already taking. Some types of medicines like steroids & blood thinning medicines are to be stopped 5-7 days prior to surgery. For admission in hospital take admission letter from your surgeon. You may be advised to get admitted 1-2 days prior to the surgery. Take all investigations report, previous medical records & drugs with you. RECOVERY – Recovery

KNEE REPLACEMENT “Total knee replacement is a surgical procedure of replacing the knee joint with an artificial prosthesis in cases of severe pain or deformity. With Newer Technique & Enhanced Recovery After surgery (ERAS), post-operatively patients are ensured of full biological range of movements post-surgery and are mobilised within the same day of surgery. “ The Knee Joint: The knee is the largest weight-bearing joint in the body. Nearly normal knee function is needed to perform routine everyday activities. The knee is made up of the lower end of the thigh bone (femur), which moves on the upper end of the shin bone (tibia), and the kneecap (patella), which slides in a groove on the end of the femur. Large ligaments attach to the femur and tibia to provide stability. The long thigh muscles give the knee strength for movement. The joint surfaces where these three bones move against each other are covered with articular cartilage, a smooth tissue that cushions the bones and enables them to move easily. All remaining surfaces of the knee are covered by a thin, smooth tissue liner called the synovial membrane. In a healthy knee, this membrane releases a special fluid that lubricates the knee and almost eliminates the friction. There are various causes of getting pain in knee joint. Osteoarthritis is one of the commonest cause of damage to the knee joint. Apart from osteoarthritis Inflammatory arthropathy like Rheumatoid arthritis and previous trauma or Fractures can result in damage to knee joint cartilage and structures. Freedom from PAIN of arthritic knee joint is now possible with Total Knee Replacement operation. If your knee has been damaged by arthritis or injury, simple activities such as walking or getting in and out of bed, going to market, standing for long time becomes difficult. Knee replacement surgery can relieve your pain and help you get back to enjoying normal, everyday activities. What is a knee replacement? Knee replacement surgery involves replacing damaged parts of your knee joint with metal or plastic parts. It’s most commonly used to treat pain and stiffness in the knee joint caused by osteoarthritis. Depending on the damage to your knee, it can be used to replace all of your knee joint (total knee replacement) or some of it (partial knee replacement). Choosing the Right Implant – Knee replacement has three main parts. A femoral component made of metal alloy like Cobalt Chrome, Oxinium or Titanium Alloy (Gold Knee). A tibial component made of Titanium Alloy Base plate and an Plastic insert made of Ultra High Molecular Polyethylene. A well-done Knee replacement easily lasts for 20 years. So it’s important to choose an implant which is time tested. Newer implants have a high flexion design matched with natural biomechanics of knee. So, one should choose implant which allows high flexion and natural movement of knee. Who is offered Knee replacement surgery? You may be offered knee replacement surgery if: You have severe pain, Swelling and Stiffness in your knee joint and your mobility is reduced. Your knee and calf pain is so severe that it interferes with your quality of life and sleep. Everyday tasks, such as shopping or getting out of the bath, are difficult or impossible. You’re feeling depressed because of the pain and lack of mobility. You cannot work or have a social life. How the operation is done – Knee replacement surgery is usually done either under general anaesthetic (you’re asleep throughout the procedure) or under spinal anaesthetic (you’re awake but have no feeling from the waist down). Sometimes you may have an epidural, which is similar to a spinal anaesthetic. Once you’ve been anaesthetised, the surgeon makes a cut (incision) on the front of your knee. The arthritic part of your thigh bone (femur) and Leg bone (Tibia) is removed and prepared for placement of new Knee replacement parts. A trial of correct size and function is done, and final Knee replacement components are implanted. The plastic insert is locked to Tibial component. The knee cycles through various movements to ensure full function of your new Knee joint. The operation takes up to 1-2 hours. POSSIBLE RISKS – Knee replacement is one of the most successful operations done on millions of patients worldwide. As with any operation, knee replacement surgery has risks as well as benefits. Most people who have a knee replacement do not have serious complications. After having a knee replacement, contact your doctor if you get: Hot, Reddened, Hard or Painful areas in your leg in the first few weeks after your operation. Although this may just be bruising from the surgery, it could mean you have DVT (deep vein thrombosis) – a blood clot in the leg. Chest pains or Breathlessness- Although it’s very rare, you could have a blood clot in your lung (pulmonary embolism) which needs urgent treatment. To reduce your risk of blood clots, you’ll be given blood-thinning medicine and compression stockings. Moving your legs as soon as you can after the operation is one of the best ways to prevent blood clots. Check with a physiotherapist what you should be doing.
