| 下肢力线与单髁假体位置角度是影响单髁置换术假体长期生存率及临床疗效的重要因素。下肢力线矫正不足将加速假体磨损进而减少假体生存率,下肢力线矫正过度会加速对侧间室关节炎的进展。通常认为单髁置换术下肢力线应纠正轻度内翻,然而部分学者的研究认为术后下肢力线对单髁置换术后功能评分和假体生存率无影响。股骨、胫骨假体位置不佳将造成患者膝关节不明原因疼痛甚至假体磨损,但股骨胫骨假体最佳位置存在争议。通常认为单髁置换术胫骨平台后倾角应纠正在3°~7°,但部分学者认为胫骨平台后倾角的改变过大也将影响膝关节间隙平衡及膝关节活动度。本文研究认为单髁置换术下肢力线的纠正至轻度内翻仍是单髁置换术最佳下肢力线,股骨与胫骨假体最佳位置有待进一步生物力学研究证实,胫骨平台后倾角的纠正应该根据术前患者具体原始解剖角度而变化。 |

| Research progress of lower limb alignment correction and prosthesis position angle in unicompartmental knee arthroplasty |
|
| Abstract:The angle between the lower extremity force line and the position of the unicondylar prosthesis is an important factor affecting the long-term survival and rate clinical outcome of the unicondylar replacement prostheses. Insufficient lower limb alignment will accelerate the wear of prosthesis and reduce the survival rate of prosthesis. Excessive lower limb alignment will accelerate the progress of contralateral interventricular arthritis. It is generally believed that the lower limb force line should be corrected in mild varus after unicompartmental knee arthroplasty. However,some scholars believe that the lower limb alignment has no effect on the functional score and prosthesis survival rate after unicompartmental knee arthroplasty. The poor position of femoral and tibial prosthesis will cause unexplained pain and even prosthesis wear,but the optimal position of femoral and tibial prosthesis is controversial. It is generally believed that the posterior tibial slope should be corrected in the range of 3° to 7° in unicompartmental knee arthroplasty,but some scholars believe that excessive change of posterior tibial slope will also affect the balance of knee joint space and knee joint range of motion. This study shows that the correction of lower limb alignment to mild varus is still the best lower limb alignment for unicompartmental knee arthroplasty. The best position of femoral and tibial prosthesis needs to be confirmed by further biomechanical research. The correction of tposterior tibial slope should be changed according to the specific original dissection angle of patients before operation. |
