Minisectomy
Removing the Damaged Tissue
A meniscectomy involves surgically removing the torn or damaged portion of the meniscus. This procedure is typically recommended when your tear is located in the inner two-thirds of the meniscus (red-white or white zones), where there is limited blood supply, making natural healing unlikely. Minisectomy Surgery can be either a partial or total, depending on the extent of the damage.
A partial meniscectomy removes only the damaged part of the meniscus, while a total meniscectomy involves the removal of the entire meniscus.
Dr Keeley may recommend a meniscectomy if:
- Non-surgical treatments have failed to heal the meniscus tear.
- The tear is large, complex, or irreparable.
- The knee joint is unstable or experiences mechanical symptoms such as locking or catching.
- Persistent pain and swelling affect daily activities and mobility.
Partial Meniscectomy:In a partial meniscectomy, Dr Keeley removes only the damaged portion of the meniscus, preserving as much healthy tissue as possible. This minimally invasive procedure is typically performed arthroscopically, meaning small incisions are made to insert a camera (arthroscope) and specialised instruments.
During A Partial Minesctomy Procedure:
- Anaesthesia: You will receive general or spinal anaesthesia to ensure comfort during the surgery.
- Arthroscopy: Dr Keeley will make small incisions around your knee to insert the arthroscope and surgical instruments.
- Trimming the Meniscus: The torn or damaged portion of the meniscus is carefully trimmed away, and the edges are smoothed to prevent further irritation.
- Completion: The instruments are withdrawn, and the incisions are closed with sutures or adhesive strips and the knee is then bandaged.
Recovery After Partial Meniscectomy:
Recovery is generally quicker than more extensive knee surgeries.
- First Week: You may bear weight on the knee shortly after surgery, often with crutches for support. Swelling and discomfort are common but can be managed with pain medication and ice. Gentle range-of-motion exercises should begin as soon as possible.
- 2 to 4 Weeks: Activity levels will gradually increase, focusing on regaining strength and mobility. High-impact activities should be avoided.
- 4 to 6 Weeks: Most patients can return to normal daily activities, but strenuous activities should be avoided until Dr Keeley confirms the knee is fully healed.
Total Meniscectomy:A total meniscectomy is usually a last resort when the meniscus is too severely damaged to be repaired or when removing only a portion would not adequately relieve symptoms or restore knee function. This procedure is performed arthroscopically, similar to a partial meniscectomy.
Long-Term Outcomes of Meniscectomy Surgery
The goal of meniscus surgery is to relieve pain, restore knee function, and prevent further joint damage. Success of the procedure largely depends on the extent of the tear, the type of surgery performed, and your adherence to rehabilitation protocols with most patients returning to their pre-surgery activities with in 4 to 6 weeks following the procedure.
