韧带断裂通常发生在沿着一条确定的线，但与韧带远端相当大的内在损伤有关。尽管如此，只要撕裂韧带的末端处于合理的并置状态，并且血液供应充足，则通过常规胶原蛋白的再生以形成具有良好拉伸强度的新韧带而发生愈合。当最近受伤后膝关节外侧不稳定提示侧副韧带断裂时，应怀疑断裂端广泛移位。只有通过外科干预才能保证准确的置换;因此，从解剖学角度来看，手术修复似乎是合理的。如果考虑手术，应该在受伤后的第一周内进行，因为这很容易实现准确的修复，但后来由于组织的收缩和脆弱性而变得不可能。为了保持血液供应，应尽可能少地干扰乳晕覆盖物，并应使用尽可能少的细缝线材料将撕裂的末端锚在适当位置。然而，当撕裂涉及上附着时，无论采用何种治疗，受损韧带的缺血都可能阻止正常愈合。
Rupture of a ligament usually occurs along a definite line, but is associated with considerable intrinsic damage to the remote parts of the ligament. In spite of this, healing occurs by regeneration of regular collagen to form a new ligament with good tensile strength, provided the ends of the torn ligament are in reasonable apposition, and provided the blood supply is adequate. When lateral instability of the knee after a recent injury suggests that a collateral ligament has been ruptured, wide displacement of the torn ends should be suspected. Accurate replacement can be guaranteed only by surgical intervention; operative repair therefore seems to be justifiable on anatomical grounds. If operation is contemplated it should be undertaken within the first week after injury when it is easy to achieve accurate repair, which later becomes impossible because of shrinkage and friability of the tissue. In order to preserve blood supply, the areolar covering should be disturbed as little as possible, and the least possible amount of fine suture material should be used to anchor the torn ends in position. Nevertheless when the tear involves the upper attachment, ischaemia of the damaged ligament may prevent normal healing, whatever the treatment adopted.
