Injury to ligaments, which will eventually result in knee instability, requires operative treatment when the radiologic tilt exceeds 3 degrees. Therapy comprises anatomic reconstruction of the capsule, ligaments, and menisci. Postoperatively, a hinge cast (limited motion cast = LMC) is applied; a range of motion of 40 degrees does not endanger stability. Excellent subjective results were found in 90% of 80 cases with acute ligamentous lesion upon follow-up examination; 77 patients returned to work after an average of 5.3 weeks after removal of the LMC; range of motion was satisfactory with full stability in 69 patients.
韧带损伤最终会导致膝关节不稳定，当影像学显示倾斜超过3度时，需要进行手术治疗。治疗包括对关节囊、韧带和半月板进行解剖重建。术后应用铰链石膏（限制活动石膏=LMC）；40度的活动范围不会危及稳定性。在对80例急性韧带损伤病例进行随访检查时，90%的患者取得了出色的主观效果；77例患者在拆除LMC后平均5.3周恢复工作；69例患者的活动范围令人满意，膝关节完全稳定。
