Isolated MCL I and MCL II lesions evidence good recovery of integrity and function under non-operative modes of treatment. Isolated MCL III lesions may also be treated by non-operative management, but with the expectation of a slightly less successful result. However, there is an 80% incidence of concomitant ligament injury with this grade of lesion. The prognosis following injury to the MCL is significantly influenced by the presence of concurrent compromise of other ligaments, particularly that of the anterior cruciate ligament. Resolution of knee instability and dysfunction following a mixed MCL injury of any grade severity is best accomplished through operative intervention. Therefore, it is the authors' opinion that isolated MCL III and all mixed MCL lesions are best managed with operative treatment. Because of the apparent influence compromise of other ligament structures have on the recovery of MCL function, an attempt must be made to repair all acutely injured structures at the time of surgery. The keystones of a satisfactory result are early and accurate diagnosis, prompt treatment, and when indicated, complete surgical repair.
单纯的内侧副韧带（MCL）I度和II度损伤在非手术治疗模式下显示出完整性和功能的良好恢复。单纯的MCL III度损伤也可采用非手术治疗，但预期效果略逊一筹。然而，该等级损伤伴有韧带损伤的发生率为80%。内侧副韧带损伤后的预后受到其他韧带同时受损的显著影响，尤其是前交叉韧带。任何严重程度的混合性MCL损伤后，膝关节不稳定和功能障碍的解决最好通过手术干预来完成。因此，作者认为单纯的MCL III度损伤和所有混合性MCL损伤最好采用手术治疗。由于其他韧带结构的损伤明显影响MCL功能的恢复，手术时必须尝试修复所有急性损伤的结构。取得满意结果的关键是早期准确诊断、及时治疗，以及在有指征时进行完整的手术修复。
