Physical therapy: To restore range of motion, strength, and stability. Weight-bearing restrictions: Gradual progression of weight-bearing activities based on surgical repair. Return to sports is usually permitted after 4–6 months, depending on the success of meniscus repair and concomitant injuries (e.g., ACL tear).
A person with a torn meniscus can sometimes remember a specific activity during which the injury was sustained. A tear of the meniscus commonly follows a trauma that involves rotation of the knee while it was slightly bent. These maneuvers also exacerbate the pain after the injury; for example, getting out of a car is often reported as painful.
Meniscus tears are a common cause of knee pain. Here, a physical therapist shares 4 exercises to help relieve meniscus pain.
The meniscus is a C-shaped piece of fibrocartilage located at the peripheral aspect of the knee joint that offers lubrication and nutrition to the joint. Each knee has two menisci, medial and lateral, whose purpose is to provide space between the tibia and the femur, preventing friction and allowing for the diffusion of articular cartilage.
Acute injury to the medial meniscus frequently accompanies an injury to the ACL (anterior cruciate ligament) or MCL (medial collateral ligament). A person occasionally injures the medial meniscus without harming the ligaments. Healing of the medial meniscus is generally not possible unless the patient is very young, usually <15 years old.
All patients are reviewed for contraindications prior to MRI scanning. Medical devices and implants are categorized as MR Safe, MR Conditional or MR Unsafe: [6] MR-Safe – The device or implant is completely non-magnetic, non-electrically conductive, and non-RF reactive, eliminating all of the primary potential threats during an MRI procedure.
MRI can also show associated bone bruises on the lateral side of the knee, which one study shows, happen in almost half of medial knee injuries. [ 19 ] Knee MRIs should be avoided for knee pain without mechanical symptoms or effusion, and upon non-successful results from a functional rehabilitation program.
A tear in the meniscus may cause a pedunculated tag of the meniscus which may become jammed between the joint surfaces. To perform the test, the knee is held by one hand, which is placed along the joint line, and flexed to complete flexion while the foot is held by the sole (of the foot) with the other hand.
