Advised exercises include stationary bicycle, standing on foam surface with two and one leg, abdominal and back strengthening, and quadriceps strengthening. The proposed criteria include normal gait on all surfaces and single leg balance longer than 15 seconds (Ulrich G.S., and S Aroncyzk, 1993). Phase III
Patients begin exercises in phase III 14 to 22 weeks after surgery. Phase IIIs goal and final criterion is to perform sport/work specific movements with no pain or swelling (Fowler, PJ and D. Pompan, 1993). Drills for maximal muscle control, strength, flexibility, movements specific to patients work/sport, low to high rate exercises, and abdominal and back strengthening exercises are all recommended exercises (Ulrich G.S., and S Aroncyzk, 1993). Exercises to increase cardiovascular fitness are also applied to fully prepare the patients to return to their desired activities. If the progression criteria are met, the patient can gradually return to "high-impact" activities (like running). However, "heavier activities", like running, skiing, basketball etc., generally any activities where knees bear sudden changes of the direction of movement can lead to repeated injuries. When planning sport activities it makes sense to consult a physical therapist and check how much impact the sport will have on the knee. Epidemiology
The meniscal tear is the most common knee injury. It tends to be more frequent in sports that have rough contact or pivoting sports such as soccer. It is more common in males than females, with a ratio of about two and a half males to one female.
The first surgery as part of US clinical trials took place in January 2015 at Ohio State Universitys Wexner Medical Center. Two FDA-approved clinical trials evaluating the implant completed enrollment in June 2018. In September 2019, the manufacturer received breakthrough designation from the U.S. Food and Drug Administration, and the company expected to file for regulatory approval  within the following year. In November 2019, the implant became commercially available in Israel.Other implants include TRAMMPOLIN and Orthonika.Scientists are working to grow an artificial meniscus in the lab. Scientists from Cornell and Columbia universities grew a meniscus inside the knee joint of a sheep using a 3-D printer and the sheeps stem cells. Similarly, researchers at Scripps Research Shiley Center for Orthopaedic Research and Education reported growing a meniscus. Post-surgical rehabilitation
After a successful surgery for treating the destroyed part of the meniscus, patients must follow a rehabilitation program to have the best result. The rehabilitation following a meniscus surgery depends on whether the entire meniscus was removed or repaired. If the destroyed part of the meniscus was removed, patients can usually start walking using a crutch a day or two after surgery. Although each case is different, patients return to their normal activities on average after a few weeks (2 or 3). Still, a completely normal walk will resume gradually, and its not unusual to take 2–3 months for the recovery to reach a level where a patient will walk totally smoothly.
