Surgery is not appropriate for a degenerative meniscus tear, absent locking or catching of the knee, recurrent effusion or persistent pain. Evidence suggests that it is no better than conservative management in those with and without osteoarthritis. Surgery appears to offer no benefit to adults who have mild arthritis.An independent international guideline panel recommended against arthroscopy for degenerative meniscus tears; this conclusion derived from evidence of no lasting benefit and that less than 15% of patients experience even a short-term benefit. Disadvantages include a two to six week recovery time and rare but serious adverse effects that can occur, including blood clots in the legs, surgical site infections, and nerve damage. The BMJ Rapid Recommendation includes infographics and shared decision-making tools to facilitate a conversation between doctors and patients about the risks and benefits of arthroscopic surgery.If the injury is isolated, then the knee would be relatively stable. However, if an injury such as an anterior cruciate ligament injury (torn ACL) is coupled with a torn meniscus, then an arthroscopy is recommended. A meniscal repair has a higher success rate given an adequate blood supply to the peripheral rim. 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. One study found that repair is better than removal (meniscectomy). The amount of rehabilitation time required for a repair is longer, but removing the meniscus can induce osteoarthritis.
Individuals between age 18 and 44 were among the highest with 37.37% total of discharges, followed by the age group 45–64, with a percentage of 36.34%. Males had a slightly higher number of discharges (50.78%) than females (48.66%). The average length of stay for both male and female patients in a hospital setting was 3.1. References
