Understanding Meniscectomy
If you’ve been experiencing knee pain, swelling, or a feeling of catching or locking, especially after a twisting injury or from gradual wear and tear, you might have a torn meniscus. If the tear is in an area that cannot heal or is causing significant mechanical problems, your doctor might recommend a Meniscectomy procedure. This surgery aims to relieve your symptoms by removing only the damaged, torn part of your meniscus.
What’s Going On with Your Meniscus?
Your knee joint, where your thigh bone (femur) meets your shin bone (tibia), contains two C-shaped pieces of cartilage called menisci (one on the inner side, the medial meniscus, and one on the outer side, the lateral meniscus). These menisci are crucial for:
- Shock absorption: Cushioning the forces between your thigh and shin bones.
- Joint stability: Helping to stabilize the knee joint.
- Load distribution: Spreading your body weight evenly across the joint surfaces.
- Lubrication: Aiding in the smooth movement of the knee.
A meniscus tear typically occurs due to:
- Twisting injuries: Especially when the foot is planted and the knee twists (common in sports).
- Forceful squatting or kneeling: Putting a lot of pressure on the menisci.
- Degeneration: In older individuals, the meniscus can weaken and tear more easily, sometimes with minimal trauma, even from everyday activities.
When the meniscus tears, it can cause pain (often along the joint line), swelling, tenderness, and mechanical symptoms like clicking, catching, or a feeling of the knee “locking up.” While some meniscus tears can be repaired (stitched back together), many tears occur in an area of the meniscus that has poor blood supply, meaning it won’t heal even if stitched. In these cases, or when a torn piece is consistently catching in the joint, a meniscectomy might be the best option.
How Does Meniscectomy Help?
A meniscectomy is a surgical procedure designed to remove only the damaged, torn portion of the meniscus. The goal is to eliminate the source of pain, catching, or locking that the torn piece is causing, while preserving as much of the healthy meniscus as possible.
This procedure is typically performed arthroscopically, meaning the surgeon uses small incisions (cuts) and a tiny camera (arthroscope) to work inside your knee joint. This minimally invasive approach often leads to:
- Smaller scars
- Less pain after surgery
- Potentially faster initial recovery and return to activities compared to a meniscal repair.
During the surgery, the surgeon will:
- Assess the Tear: The arthroscope provides a clear view of the meniscus tear. The surgeon will confirm that the tear is not repairable or that a meniscectomy is the most appropriate treatment.
- Trim the Damaged Tissue: Using small, specialized arthroscopic instruments, the surgeon carefully trims away only the unstable, torn fragments of the meniscus. The goal is to create a smooth, stable edge for the remaining healthy meniscus. No stitches are usually involved in a meniscectomy.
Life After Meniscectomy:
After your meniscectomy, physical therapy is important to help you regain full strength and function in your knee. While recovery is often quicker than a meniscus repair or other more extensive knee surgeries, rehabilitation is still crucial to ensure the best possible outcome. Your physical therapist will guide you through a structured rehabilitation program, which typically includes:
- Pain and Swelling Management: Techniques to reduce discomfort and swelling around your knee.
- Early Movement Restoration: You’ll typically begin weight-bearing and gentle exercises soon after surgery to restore the full range of motion in your knee.
- Progressive Strengthening: Your therapist will introduce exercises to strengthen the muscles around your knee (quadriceps, hamstrings, glutes) and core, which are vital for supporting the joint.
- Balance and Proprioception Training: Exercises to improve your stability and coordination as you return to activities.
- Functional Return: Your therapist will help you gradually return to your daily activities, work tasks, and sports, focusing on proper mechanics to protect the remaining meniscus and the rest of your knee joint.
Recovery from a meniscectomy is generally faster than more complex knee surgeries, often allowing a return to most activities within a few weeks to a couple of months. Following your physical therapist’s instructions and listening to your body are crucial for achieving the best possible outcome and safely returning to your desired activities.
