部件设计是影响术后屈曲角的因素之一。本研究旨在比较后交叉韧带保留型（CR）全膝关节置换术（TKA）中平面和内侧枢轴设计的短期结局。一项回顾性、病例对照和观察性队列研究，包括CR-TKA中平面设计（Hi-Tech Knee II）和内侧枢轴设计（FINE Knee）的配对，随访期为2年。Hi-Tech Knee II和FINE膝关节组各包括7名男性和38名女性。FINE膝关节组的手术时间显著短于Hi-Tech膝关节II组（104.8 min vs 154.9 min，p = 0.001）。FINE Knee组的估计总失血量显著低于Hi-Tech Knee II组（654 ml vs 1158 ml，p = 0.001）。FINE膝关节组的术后屈曲角度明显优于Hi-Tech膝关节II组（119.3度vs 112.5度），并且与术前屈曲角度呈正相关。FINE膝关节组的术后膝关节协会评分显著优于Hi-Tech膝关节II组（93.0分vs 85.0分，p = 0.001），尤其是术后疼痛缓解（46.0分vs 39.0分，共50分，p = 0.001）。在两年的随访期内，两组均未观察到并发症。CR-TKA中使用的内侧枢轴设计的短期结局比平面设计更有利，特别是在手术时间、估计总失血量、术后屈曲角度和膝关节疼痛方面。本文的在线版本（10.1186/s12891-018-2138-z）包含补充材料，可供授权用户使用。
Component design is one of the contributory factors affecting the postoperative flexion angle. The purpose of this study was to compare short-term outcomes of flat surface and medial pivot designs in posterior cruciate-retaining (CR) total knee arthroplasty (TKA). A retrospective, case-control, and observational cohort study consisted of matched-pairs of the flat surface design (Hi-Tech Knee II) and the medial pivot design (FINE Knee) in CR-TKA with a two-year follow-up period. Hi-Tech Knee II and FINE knee groups each included 7 males and 38 females. Surgical time was significantly shorter in the FINE Knee group than in the Hi-Tech Knee II group (104.8 min versus 154.9 min, p = 0.001). Estimated total blood loss was significantly lower in the FINE Knee group than in the Hi-Tech Knee II group (654 ml versus 1158 ml, p = 0.001). The postoperative flexion angle was significantly better in the FINE Knee group than in the Hi-Tech Knee II group (119.3 degrees versus 112.5 degrees), and was positively correlated with the preoperative flexion angle. Postoperative Knee Society scores were significantly better in the FINE Knee group than in the Hi-Tech Knee II group (93.0 points versus 85.0 points, p = 0.001), especially for postoperative pain relief (46.0 points versus 39.0 points out of 50, p = 0.001). Complications were not observed in either group over a two-year follow-up period. The short-term outcome of the medial pivot design used in CR-TKA was more favorable than the flat surface design, especially for surgical time, estimated total blood loss, postoperative flexion angle, and knee pain.
