The effects of repair, motion, and the integrity of the secondary ligamentous restraints on healing of the medial collateral ligament were studied in a rat model. Healing was assessed by measuring ligamentous laxity and tensile strength. All healing ligaments were weaker and more lax than their controls. Repair did not have a statistically significant effect on the laxity or the strength of the medial collateral ligament. Allowing active motion had a statistically significant beneficial effect on the strength of the medial collateral ligament. Stability was adversely affected by active motion if the secondary restraints had been transected; however, when the secondary ligamentous restraints were intact, active motion was beneficial and immobilization was harmful.
在大鼠模型中研究了修复、活动以及二级韧带限制结构的完整性对内侧副韧带愈合的影响。通过测量韧带松弛度和拉伸强度来评估愈合情况。所有愈合的韧带都比其对照韧带更脆弱、更松弛。修复对内侧副韧带的松弛度或强度没有统计学上的显著影响。允许主动活动对内侧副韧带的强度有统计学上的显著有益影响。如果二级限制结构已被横断，主动活动会对稳定性产生不利影响；然而，当二级韧带限制结构完整时，主动活动是有益的，而固定则是有害的。
