Meniscal repair: Preferred for young patients or those with tears in the vascular (red-red) zone, which has healing potential. Arthroscopic sutures are used to repair the torn meniscus. Partial meniscectomy : [ 7 ] If the tear is in a non-repairable location (white-white zone) or the meniscal tissue is extensively damaged, the displaced ...
A meniscal repair has a higher success rate given an adequate blood supply to the peripheral rim. [36] [failed verification] The interior of the meniscus is avascular, but the blood supply can penetrate up to about 6 millimetres (0.24 in). Therefore, meniscus tears that occur near the peripheral rim are able to heal after a meniscal repair. [1]
Another procedure requires specially designed devices that employ multiple sutures and knot pusher instruments to allow surgeons to provide excellent meniscal repair with just a single 1 ½” incision. [citation needed] The majority of meniscal tears are not suitable for repair and instead the torn piece is removed, known as a meniscectomy ...
Treatment of meniscal cysts consists of a combination of cyst decompression (intraarticular decompression versus open cystectomy) and arthroscopic repair of any meniscal abnormalities. Success rates are significantly higher when both the cyst and meniscal tear are treated compared to treating only one disease process.
The quality of the repair tissue after these "bone marrow stimulating techniques" depends on various factors including the species and age of the individual, the size and localization of the articular cartilage defect, the surgical technique, e.g., how the subchondral bone plate is treated, and the postoperative rehabilitation protocol.
In terms of a meniscus tear, the doctor can categorize the injury in a plethora of ways. For example, a tear on the outer edge of the meniscus has great chance of healing. Doctors call this site the “red zone” because this outer portion of the meniscus is highly vascularized; therefore, it receives the amount of nutrients and support needed ...
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.
Acute tears have many different shapes (vertical, horizontal, radial, oblique, complex) and sizes. They are often treated with surgical repair depending upon the patient's age as they rarely heal on their own. Chronic tears are treated symptomatically: physical therapy with or without the addition of injections and anti-inflammatory medications.
