Commonest knee problem is meniscus injury. Meniscus is a small cushion between knee bones and transmit load equally. In activities where knee goes into deep bending especially sudden jumping or when doing weighted squats - the meniscus gets trapped between bones and gets torn. There may be sound which can be heard when injury happens. There is feeling of locking and knee swelling. Such knee injury is a serious knee injury as meniscus if left torn it rubs on joint cartilage surface resulting in arthritis and joint damage
It is important to perform muscle strengthening exercises and Core balancing exercises so as to prepare the knee for sudden jerks and twists.
I get a normal Knee MRI. It helps me in understanding the type and the extent of tear. I can evaluate shape, size and extent of tears. Small tears which are stable do heal with time but tears which are unstable and big and in vascular area often need meniscus repair.
Meniscus is shock absorber of knee and injury to it causes excessive loads on knee bone and friction . If the torn part of meniscus is removed it causes abnormal joint loading and thus early joint degeneration
Meniscus repair is technically demanding procedure which restores the knee cushion thus giving knee normal surface. I use various techniques - All Inside, Inside out and Outside in depending on tear locations. I use special sutures, devices and implants to repair the meniscus back.
Meniscus healing is slow and needs protection in post operative period. Weight bearing is restricted on operated leg for few days though walking is allowed in 24 hours but with walker support . Knee bending exercises are initially slowly started and in few days increased. Meniscus tears heal by 6-8 weeks and then aggressive exercises are restarted to get strength back
