Weakness, grinding, instability or giving way rarely result from meniscal pathology. The menisci are "wedge-shaped" pieces of cartilage that rest between the thigh bone ("femur") and lower leg bone ("tibia") in the knee joint. Perhaps the best know of these is the bucket-handle tear. Two wedge-shaped pieces of fibrocartilage act as shock absorbers between your femur and tibia. So the injury as seen in MRI scan means there is an tear in the medial meniscus towards the posterior side, that is towards the back of joint. Meniscus tears are extremely common knee injuries. Meniscus Injuries - The Steadman Clinic Adjunctive measures to promote vascularity and healing at the repair sites are also recommended. Arnoczky SP, Warren RF, Spivak JM. As such, it is critical to repair medial meniscal root tears during ACL reconstruction to help stabilize the knee, as well as to decrease stresses that the graft experiences. In addition to categorizing meniscal tears based on morphology, care should be taken to describe the exact location of meniscal tears. The RICE protocol is effective for most sports-related injuries. This technique allows for anatomic reduction and fixation of the meniscal root by restoring the joint contact pressure and area similar to the intact state. J Fam Pract 2001;50:93844. Explains two kinds of surgery. J Bone J Surg Am 2006;88:6607. We believe that by repairing these tears, the degenerative process may be delayed or halted (Figure 6). In case of an open or unstable fracture, the bone may protrude out of the skin surface and be exposed to environmental contaminants. This leads to decreased contact area and increased contact pressure and ultimately results in joint overloading and degenerative changes in the knee similar to a total meniscectomy state. You might develop the following signs and symptoms in your knee: A popping sensation. RICE stands for Rest, Ice, Compression, and Elevation.

Posterior Horn Meniscus Tears All material on this website is protected by copyright. McMurray (Figure 1) and Apley tests (Figure 2) are often positive, although these are specific but not sensitive specificity being 5798% and 8099%, and sensitivity being 1066% and 1658% respectively.2,9 The most useful clinical test for meniscal injury is the Thessaly test, which is demonstrated in Figure 3.

Tears present as severe pain, swelling, and possibly catching, clicking, difficulty on deep knee bending and locking of the knee in partial flexion. Our preferred repair method utilizes a two-tunnel transtibial pull-out technique. Because there is no supply, there is little capacity for these tears to heal on their own.

See your ortho for an evaluation. (16a) Sagittal and (16b) axial proton density weighted images reveal a very large radial tear (arrows) that extends broadly across the entire width of the anterior body of the lateral meniscus. This tear is usually best seen on the coronal T2-weighted MRI scan (see figure 1), where a fragment of meniscus (black in appearance) is stuck between the medial tibial plateau and the overlying medial collateral ligament.This tear pattern tends to be persistently painful, as the meniscal fragment becomes entrapped between bone and the adjacent soft tissues. https://orthop.washington.edu/patient-care/articles/sports/torn-meniscus.html, Phone The treatment of these type of tears can be either arthroscopy (surgery through a tiny hole in knee) or conservative.

Repair is sometimes attempted even with these tear types, particularly when the patient is young and substantial loss of meniscal tissue would lead to an unacceptable risk of future arthritis.11 Repair of these challenging tear types should only be attempted when the meniscal tissue is of good quality and a stable result is achievable. Two months later, the post-operative image (17b) reveals a repaired, normal appearing lateral meniscal body (arrow), with resolution of the previously seen displaced fragment. American Board of Orthopaedic Surgery Practice of the Orthopaedic Surgeon: Part-II, certification examination case mix. Research is currently investigating the possibility of implantation of collagen, allogenic and xenogenic cells, embryonic and adult stem cells, or scaffolds derived from polymers, hydrogels, tissues and extracellular matrix,7 and action of biological stimuli (eg. Studies have also reported that patients who underwent a repair of the posterior root in the medial meniscus slowed the progression of arthritic changes compared with those who had a meniscectomy; although, this did not completely prevent the arthritic changes. Full thickness tears are the complete disruption of the fibers of the supraspinatus muscle, and generally require a more aggressive treatment plan and surgery.
