Unicondylar Knee Replacement in Pune

Discover Cutting-Edge Solutions for Knee Pain with our Unicondylar Knee Replacement Surgery

Unicondylar knee replacement surgery, also known as partial or unicompartmental knee replacement, is an advanced orthopaedic procedure designed to address knee pain and restore mobility in patients suffering from localised knee arthritis. Unlike total knee replacement, which involves replacing the entire knee joint, unicondylar knee replacement targets only the damag
ed portion of the knee, preserving healthy tissue.

During the surgery, the orthopaedic surgeon removes damaged cartilage and bone from the affected area and replaces them with artificial components, typically made of metal and plastic. This precise approach allows for smaller incisions, shorter recovery times, and greater range of motion post-surgery. Unicondylar knee replacement is particularly beneficial for patients with arthritis limited to one specific area of the knee and healthy ligaments. This advanced treatment option provides relief from knee pain and the opportunity for a quicker return to an active lifestyle.

When Is Surgery Recommended

Surgery for unicondylar knee replacement is recommended in specific situations, primarily when conservative treatments have proven ineffective in managing knee pain and limited mobility caused by localised knee arthritis. The decision to undergo surgery is typically based on the following criteria:

Diagnosis of Unicompartmental Osteoarthritis: Surgery is recommended when a patient is diagnosed with unicompartmental osteoarthritis, meaning that the arthritis is limited to one specific area or compartment of the knee joint.

Inadequate Pain Relief: If non-surgical interventions such as physical therapy, medications, lifestyle modifications, and joint injections no longer provide sufficient pain relief, and the patient's quality of life is significantly impacted by knee pain.

Difficulty with Mobility: When knee arthritis leads to significant stiffness and difficulty in walking, causing limitations in daily activities and reducing overall mobility.

Damage Confined to a Single Compartment: The arthritis damage must be localised to one compartment of the knee, mainly medial or lateral compartment allowing for a partial replacement without affecting the healthy portions of the joint.

Ligaments in Good Condition: The knee ligaments surrounding the affected compartment should be in good condition, particularly the ACL ligament as this contributes to the success of the procedure.

Thorough Evaluation: Patients are evaluated through physical examinations and imaging tests such as X-rays and MRI scans to determine the extent and location of the knee damage before surgery is recommended. Also clinical evaluation should have minimal fixed deformities like Varus or flexion deformity with the aim of ensuring that the patient is a suitable candidate for the recommended surgical procedure.


The procedure for unicondylar knee replacement at Polaris HealthCare involves a thorough pre-operative evaluation to ensure a safe and successful surgery. This evaluation includes a comprehensive physical examination, laboratory testing, and diagnostic imaging to assess your knee's condition and overall health. These findings help our skilled surgeons create a personalised risk profile for each patient, enabling them to anticipate potential challenges and minimise the risk of early implant failure.

During the surgical procedure, our experienced surgeon makes a small incision to access the damaged knee compartment. With precision and care, the surgeon gently moves the knee's supporting components aside, providing access to the arthritic tibia and femur. These surfaces are meticulously cleaned of worn-out cartilage and damaged bone tissue. In essence, unicondylar knee replacement involves replacing only the affected portion of the knee joint, using a smaller incision compared to the one required for a complete knee replacement. This minimally invasive approach aims to relieve pain, restore mobility, and enhance the overall quality of life for our patients.

Post-Surgery Care

Post-surgery care is crucial for a successful recovery following unicondylar knee replacement. While most patients describe the post-operative pain as minor or tolerable, it's essential to manage discomfort effectively. Here are some important steps to take during the recovery process,

  • Use a cushion under your calf or ankle (not your knee) to raise your leg above heart level.

  • Apply ice for 20 minutes, three to four times daily, using a cloth as a barrier.

  • Take prescribed oral painkillers as directed for discomfort management.

  • Stay in touch with your surgeon; if knee discomfort worsens or you have concerns, contact them promptly.

  • Follow the prescribed schedule for dietary supplements and medications.

  • Participate in recommended physiotherapy sessions to regain knee strength and mobility.


1. How can I tell if I need revision knee replacement surgery?

The need for revision knee replacement is often indicated by persistent symptoms such as severe knee pain, decreased joint function, instability, swelling, or stiffness in the knee joint. If you experience any of these issues following your initial knee replacement, it's essential to consult with your orthopaedic surgeon for a thorough evaluation, which may include imaging tests like X-rays and clinical assessments.

2. Can I expect the same results with revision knee replacement as I did with the initial replacement?

While revision knee replacement aims to improve pain relief and restore function, outcomes can vary depending on the reason for the revision and the extent of the issues. Some patients may achieve results similar to their initial knee replacement, while others may experience persistent pain or limitations. The success of the revision surgery is influenced by factors like the patient's overall health, the reason for revision surgery , the osteoporosis and the bone and muscle strength  and adherence to post-operative care.

3. Is infection common in revision knee replacement surgery?

Infection is a potential risk associated with any surgical procedure, including revision knee replacement. However, the risk of infection is generally lower than 1%. To minimise this risk, orthopaedic surgeons take meticulous precautions, such as using antibiotics before and after surgery and maintaining sterile surgical techniques. If an infection does occur, it may require specific treatment, including antibiotic therapy and, in severe cases, removal of the implant.

4. Can I resume my normal activities after revision knee replacement surgery?

The ability to resume normal activities after revision knee replacement depends on various factors, including the patient's pre-existing health, the success of the surgery, and rehabilitation progress. Many patients can regain a significant level of mobility and functionality following rehabilitation. However, it's important to follow the guidance of your orthopaedic surgeon and physical therapist to ensure a safe and successful recovery.

5. How long do revision knee implants typically last?

The longevity of revision knee implants can vary depending on factors such as the patient's age, activity level, and the specific implant used. In most cases, revision knee replacements are expected to function well for at least 15 to 20 years in a significant percentage of patients (85% to 90%) due to advancements in implant design and surgical techniques. However, it's essential to maintain a healthy lifestyle and follow up with your surgeon for routine assessments to maximise the lifespan of the implant.
