This study investigated the effect of mediolateral stability on sagittal stability in bi-cruciate stabilized total knee arthroplasty.
This study included 59 patients. We intraoperatively assessed the component gap with a joint distraction force of 60 N for each compartment. Immediately after surgery, sagittal stability was assessed using an arthrometer.
The intraoperative medial joint laxity at 30° of flexion was significantly correlated with postoperative anteroposterior translation (r = 0.276, p < 0.05).
This study demonstrated the effect of intraoperative mediolateral stability effect on postoperative sagittal stability. Improving medial stability may enhance postoperative sagittal stability.
本研究调查了在双交叉韧带稳定型全膝关节置换术中,内外侧稳定性对矢状面稳定性的影响。
本研究纳入了59例患者。我们在术中用60N的关节牵张力评估每个关节间室的组件间隙。术后立即使用关节测量仪评估矢状面稳定性。
术中屈膝30°时的内侧关节松弛度与术后前后向移位显著相关(r = 0.276,p < 0.05)。
本研究证明了术中内外侧稳定性对术后矢状面稳定性的影响。改善内侧稳定性可能会增强术后矢状面稳定性。
