Cho dù trong một đầu gối ổn định hoặc không ổn định một năm, nếu không một giọt nước mắt khum | Meniscus Tears Treatment in the Stable and Unstable Knee John P. Belzer MD and W. Dilworth Cannon Jr MD Abstract Basic science research and follow-up studies after meniscectomy have provided convincing evidence of the importance of preservation of the meniscus in decreasing the risk of late degenerative changes. Whether in a stable or an unstable knee if a meniscus tear cannot be repaired a conservative partial meniscectomy should be undertaken to preserve as much meniscal tissue as possible. When feasible repair should be carried out in young patients with an isolated meniscus tear despite healing rates that are significantly lower than those obtained when meniscus repair is done with anterior cruciate ligament ACL reconstruction. The incidence of successful healing is inversely related to the rim width and tear length. In general meniscus repair should be limited to patients under 50 years of age. Vertical longitudinal tears including bucket-handle tears are most amenable to repair. Some radial split tears can be repaired. In an ACL-deficient knee meniscus repair is more prone to failure if not performed in conjunction with an ACL reconstruction and is not recommended. Meniscal allograft surgery is investigational but may hold promise for selected patients. J Am Acad Orthop Surg 1993 1 41-47 As our understanding of meniscus function has developed the need for more constructive treatment modalities to preserve this function has become apparent. Whereas total meniscectomy was the standard of care in the past this procedure is now reserved for those cases in which meniscus degeneration is Currently it is felt that many torn menisci can and should be repaired. When a meniscus tear is not amenable to repair partial meniscectomy is the preferred treatment1-4 if it is not possible to simply leave the tear alone. This change in treatment strategy has been the result of improved arthroscopic techniques 4 better understanding of the healing potential of the .
