  • What Is Partial Knee Replacement Surgery?

    Partial knee replacement surgeries are specialized medical procedures targeted at treating knee joint damage confined to a specific compartment of the knee. This surgery is often the preferred choice when only a part of the knee is severely affected by arthritis or injury, allowing for less invasive interventions and quicker recoveries. Orthopaedic surgeons, who specialise in bone and joint issues, perform this procedure. 

    The necessity for partial knee replacement surgery stems from its ability to relieve pain, restore mobility, and improve the quality of life in patients who have not found relief through more conservative treatments such as medication or physical therapy. 

    This partial knee replacement procedure offers significant benefits over total knee replacement, including reduced surgical risks and preservation of the knee’s natural anatomy.

    What Are The Types Of Partial Knee Replacement Surgery?

    Partial knee replacement surgeries can be categorised based on the compartment of the knee they target:

    • Unicompartmental (unicompartmental knee arthroplasty): This type is performed when only one knee compartment is damaged.
      • Medial compartmental knee replacement — for damage on the inside of the knee.
      • Lateral compartmental knee replacement — for damage on the outside of the knee.
    • Bicompartmental knee replacement: This surgery addresses two damaged compartments of the knee, often involving both the femur (thigh bone) and tibia (shin bone) surfaces.
    • Patellofemoral replacement: This type specifically replaces the area of the knee behind the kneecap (patella) and the front of the femur. It’s suitable for patients whose anterior knee compartment is affected.

    These types address different areas of knee damage, offering tailored treatments that preserve as much of the knee’s natural structure and function as possible, reducing recovery time and improving surgical outcomes.

    Are you going through any of these symptoms?

    Diagnosis Before Partial Knee Replacement Surgery

    Before proceeding with a partial knee replacement surgery, accurate diagnosis is crucial to ensure that this treatment is the most appropriate option for the patient. The diagnosis process typically involves:

    • Physical Examination: An orthopaedic surgeon assesses the knee’s range of motion, stability, strength, and overall alignment.
    • Imaging Tests:
      • X-rays: These are the primary diagnostic tool used to identify the extent of knee damage and are critical in determining if the damage is localised to one part of the knee.
      • Magnetic Resonance Imaging (MRI): Offers detailed images of both bone and soft tissues, including cartilage and ligaments.
      • Computed Tomography (CT) Scan: Sometimes used to provide a clearer picture of the knee’s anatomy, which can help in surgical planning.
    • Diagnostic Arthroscopy: In some cases, a surgeon may perform this minimally invasive surgery using a camera to inspect the inside of the joint directly.

    These diagnostic steps are vital to crafting a personalised partial knee replacement surgery preparation plan that maximises the procedure’s effectiveness and patient’s safety. Each diagnostic tool provides valuable insights that help in deciding not only the necessity of the surgery but also the specific type of partial replacement required.

    What Is The Procedure For Partial Knee Replacement Surgery?

    The partial knee replacement procedure is a less invasive alternative to total knee replacement, aimed specifically at those suffering from osteoarthritis in only one part of the knee. This procedure is designed to replace only the damaged sections of the knee, preserving as much of the original joint as possible. Here’s what patients can expect during the surgery:

    • Preoperative Preparation: Patients undergo a thorough pre-surgical assessment including medical evaluations and partial knee replacement surgery preparation to ensure they are fit for surgery.
    • Anaesthesia: General or spinal anaesthesia is administered to ensure the patient is comfortable and pain-free during the procedure.
    • Incision: The surgeon makes a small incision in the knee to access the affected compartment.
    • Removal of Damaged Cartilage and Bone: Precision tools are used to remove the damaged surfaces of the knee joint.
    • Implant Placement: Custom-fitted implants made of metal and plastic components replace the removed cartilage and bone, mimicking the natural curvature and movement of the knee.
    • Testing the Movement: The new joint components are tested by flexing and extending the knee to ensure they fit perfectly and function correctly.
    • Closure: The incision is closed with stitches or surgical staples, and a sterile bandage is applied.
    • Postoperative Care: Post-surgery, patients are moved to a recovery area where they are closely monitored as the anaesthesia wears off.

    This streamlined procedure is designed to minimise trauma to the body and speed up recovery time, allowing patients to return to their normal activities sooner.

    Who Is The Right Candidate For Partial Knee Replacement Surgery?

    Identifying the right candidates for partial knee replacement surgeries is crucial for ensuring the success of the procedure. Ideal candidates typically:

    • Have osteoarthritis confined to one compartment of the knee, which has not responded to non-surgical treatments such as medication or physical therapy.
    • Are experiencing significant pain that interferes with daily activities and quality of life.
    • Have intact knee ligaments, as these are essential for the stability of the knee post-surgery.
    • Are generally in good health, without active infections or medical conditions that would impede healing and recovery.

    Patients who meet these criteria are likely to experience the most benefit from this targeted surgical approach, leading to better outcomes and a more active lifestyle post-surgery.

    What Are The Benefits Of Partial Knee Replacement Surgery?

    The benefits of partial knee replacement surgery are significant, making it a valuable treatment option for suitable candidates. Key benefits include:

    • Reduced Trauma to the Knee: Since only the affected part of the knee is replaced, there is less trauma to the knee joint compared to total knee replacement.
    • Quicker Recovery: Patients generally experience a faster recovery, with many returning to normal activities within weeks.
    • Less Pain Post-Surgery: With smaller incisions and preservation of more natural knee tissue, patients often report less pain during the recovery period.
    • Improved Joint Function: The surgery allows for a more natural knee movement since the unaffected parts of the knee are preserved.
    • High Success Rates: Partial knee replacement surgeries have high success rates with improved surgical techniques and implant quality.

    These benefits highlight the effectiveness of partial knee replacement in restoring mobility and reducing pain, significantly improving the quality of life for patients.

    How To Prepare For Partial Knee Replacement Surgery?

    Partial knee replacement surgery preparation involves several key steps to ensure the best possible outcomes. Proper preparation can significantly impact the success of the surgery and the speed of recovery. Here’s how patients can prepare:
