Partial Knee Replacement Surgery in Mumbai, India

Partial knee replacement is a surgical procedure designed to alleviate pain and restore function in patients suffering from localised knee joint damage, often due to osteoarthritis. Mumbai, a bustling metropolis in India, offers top-notch medical facilities and experienced orthopaedic surgeons who specialise in partial knee replacements, making the city a sought-after destination for individuals seeking partial knee replacement surgery.

When is Partial Knee Replacement Recommended?

Partial knee replacement becomes a viable option when conservative treatments, such as medication, physical therapy and lifestyle modifications, fail to provide adequate pain relief and functional improvement. Here are some scenarios in which partial knee replacement is often recommended:

• Localised Knee Damage: Partial knee replacement might be considered when the knee joint damage is limited to a single compartment, which can be either the inner (medial), outer (lateral), or the area beneath the kneecap (patellofemoral compartment).
• Pain and Disability: Patients experiencing significant pain, swelling and limitations in daily activities due to knee joint deterioration may be candidates for partial knee replacement.
• Limited Arthritis Severity: Partial knee replacement is most effective in cases where arthritis is mild to moderate, and the majority of the knee remains healthy. This procedure is not typically recommended for severe arthritis affecting all knee compartments.
• Patient Preference: In some cases, patients may opt for partial knee replacement due to its advantages, including faster recovery and less post-operative pain, compared to total knee replacement.

Preparing for Partial Knee Replacement Surgery

Some important steps and factors that individuals should bear in mind when getting ready for partial knee replacement surgery:

• Patients should consult an experienced orthopaedic surgeon specialising in knee replacements. The surgeon will evaluate their medical history, conduct a physical examination and order imaging tests to assess the extent of knee damage and determine if partial knee replacement is suitable.
• Patients should adhere to their surgeon's advice for managing chronic conditions like diabetes or hypertension, cease smoking if applicable and sustain a well-balanced diet. Maintaining good overall health can improve surgical outcomes.
• Patients should have a conversation with their partial knee replacement doctor about the medications they are currently taking. It may be necessary to modify or temporarily stop certain drugs before surgery to lower the chances of complications.
• Engaging in pre-operative physical therapy is advisable to strengthen the muscles around the knee and improve joint mobility to facilitate a smoother recovery.
• Adequate arrangements at home should be made, such as installing handrails, adjusting furniture, a person for physical support to do daily activities and creating a comfortable recovery space.

Diagnosis or Test for Partial Knee Replacement Surgery

Before undergoing partial knee replacement surgery, patients typically undergo a series of diagnostic assessments to ensure the procedure's appropriateness and to gather essential information for the surgical team. These include:

• A comprehensive physical examination involving an assessment of the patient's medical history, range of motion and joint stability is the initial step.
• X-rays are often used to visualise the knee joint, estimate the level of injury and establish which compartments are impacted. Magnetic Resonance Imaging (MRI) can also provide a more detailed picture.
• Routine blood tests may be performed to check the patient's overall health and identify any underlying medical issues that could interfere with the surgery.
• Dual-energy X-ray absorptiometry (DEXA) scans may be conducted to evaluate bone density, which can influence implant fixation.
• Patients may undergo physical therapy assessments to evaluate knee function, strength and mobility.

Partial Knee Replacement Procedure

Surgical Approach and Techniques

During a partial knee replacement procedure, an orthopaedic surgeon employs a minimally invasive surgical approach aimed at addressing localised knee joint damage, typically caused by osteoarthritis. The surgeon selectively replaces only the affected knee compartment, either the medial (inner), lateral (outer), or patellofemoral (under the kneecap), while preserving the healthy portions of the joint.

Anesthesia and Incision

Patients receive either general anaesthesia or regional anaesthesia, such as spinal or epidural anaesthesia, depending on the condition and the surgeon's preference. Once the anaesthesia takes effect, a small incision is made over the knee joint to access the damaged compartment. This incision is notably smaller than those used in total knee replacement procedures.

During the Procedure

During the process, the surgeon meticulously removes damaged cartilage and bone from the affected knee compartment. Specialised instruments and precision guides assist in accurate implant placement. A prosthetic component is then inserted to replace the removed tissue. The surgeon ensures proper alignment and fit to restore the joint's function. Sometimes, computer-assisted navigation may be used for enhanced precision.

After the Procedure

Following the surgery, patients typically spend a brief period in a recovery area before being moved to a hospital room. Physiotherapy begins promptly to promote joint mobility and strength. Patients may experience less pain and a quicker recovery compared to total knee replacement. After discharge, they continue rehabilitation exercises to regain full function. Post-operative care and follow-up appointments are done to monitor progress and recovery.

Benefits of Partial Knee Replacement

Targeted Pain Relief and Improved Function

Partial knee replacement surgery offers several benefits to patients. Firstly, it provides targeted pain relief and improved joint function. By addressing only the damaged compartment of the knee while preserving healthy tissue and ligaments, patients often experience reduced post-operative pain. This surgical approach specifically targets the source of discomfort, making it highly effective in alleviating pain associated with localised osteoarthritis or knee damage. Patients can expect improved joint function and physical mobility.

Quicker Recovery and Rehabilitation

Another significant advantage of partial knee replacement is the shorter recovery time compared to total knee replacement. With less tissue disruption and trauma, patients often experience a quicker return to their normal activities. Rehabilitation and physical therapy can commence earlier, facilitating the restoration of strength and mobility in the affected knee. This quicker recovery allows individuals to regain their independence and resume their regular routines with minimal disruption.

Recovery and Rehabilitation After Partial Knee Replacement

Hospital Stay and Postoperative Care

• After undergoing a partial knee replacement, patients typically spend a short duration in the hospital, often ranging from one to three days. The patient's condition is continuously monitored throughout this period to make sure that pain is appropriately controlled and there are no complications. Medication for pain management may include both painkillers and anti-inflammatory medicines.
• The medical staff will also instruct patients on wound care to prevent infection, and patients are encouraged to begin gentle movements of the operated knee to prevent stiffness.
• Upon discharge, patients receive comprehensive postoperative care instructions. These instructions include guidance on wound care, medication schedules, diet and any restrictions on activities or weight-bearing, depending on the surgeon's recommendations.

Physical Therapy and Exercises

• Physical therapy is an important aspect of the rehabilitation process following a partial knee replacement. Physical rehabilitation is usually started within a day or two of surgery. Physiotherapists provide individualised exercise programmes to improve joint mobility, strength and function.
• Initially, therapy focuses on gentle range-of-motion exercises and strengthening exercises for the quadriceps and surrounding muscles. As the patient progresses, exercises become more challenging to promote full recovery. Patients are also educated on the proper techniques for walking, climbing stairs and performing daily activities with their new joint.

Partial Knee Replacement Risks and Complications

In the context of partial knee replacement surgery, there are several potential risks and complications that patients should be aware of:

Infection and Blood clots

Although surgical sites are carefully sterilised, infections can still occur. Signs of infection may include increased pain, redness, swelling or discharge from the surgical site. Early detection and prompt treatment with antibiotics are essential to mitigate this risk.

Another concern is the development of blood clots in the legs, known as deep vein thrombosis (DVT). These clots can be potentially life-threatening if they travel to the lungs, causing a pulmonary embolism. Patients are frequently prescribed blood-thinning drugs and encouraged to engage in early mobility and leg exercises to reduce the risk of DVT.

Implant Wear and Loosening

Over time, partial knee replacement implants may experience wear and tear, potentially leading to complications. Implant wear can cause joint instability, pain and reduced function. Additionally, the implant may become loose, which can result in pain and diminished joint mobility. These issues may necessitate revision surgery to replace or adjust the implant.

Frequently Asked Questions

1. Is It Worth Doing A Partial Knee Replacement?

When only a portion of the knee joint is compromised, partial knee replacement can provide targeted pain relief and a faster recovery than full knee replacement. However, the decision should be taken after consulting with an orthopaedic specialist who can analyse the extent of knee damage and determine whether partial knee replacement is appropriate for the individual's situation.

2. Which is Better: Partial or Full Knee Replacement?

The choice between partial and full knee replacement depends on the patient's specific condition. Partial knee replacement is advantageous when the damage is limited to one compartment of the knee, preserving healthy tissue and ligaments. It often results in quicker recovery and less post-operative pain. In contrast, full knee replacement is necessary when all compartments of the knee are affected.

3. How Long Does It Take To Recover From a Partial Knee Replacement?

Although recovery timeframes vary, many patients can resume light activities within a few weeks of the surgery. However, complete healing could take months. Physical therapy and rehabilitation are critical components of the recovery process, assisting patients in regaining strength and mobility.

4. Can You Climb Stairs After Partial Knee Replacement?

Yes, most patients can climb stairs after a partial knee replacement. In fact, regaining the ability to climb stairs is an essential aspect of postoperative rehabilitation. Physical therapy will include exercises to improve stair-climbing ability and overall mobility.

5. What are The Restrictions After Partial Knee Replacement?

Restrictions may include avoiding high-impact activities, such as running or jumping, and being cautious when engaging in activities that involve twisting or excessive stress on the knee. Patients should avoid activities that could potentially damage the implant or compromise the joint's stability.

6. How Much Can You Walk After Partial Knee Replacement?

The ability to walk after partial knee replacement varies from person to person and depends on various factors, including preoperative fitness level and the extent of rehabilitation. Most patients can resume walking shortly after surgery, gradually increasing their walking distance as they progress through the recovery process.

7. What Do I Need At Home After Partial Knee Replacement?

After partial knee replacement surgery, it's important to have certain items at home to facilitate recovery. These may include mobility aids like crutches or a walker, comfortable and supportive footwear, assistive devices for activities of daily living (e.g., a reaching tool), over-the-counter pain medications (as prescribed by the surgeon) and a comfortable and elevated resting area to minimise swelling.
