This study aimed at evaluating the changes in passive range of motion (ROM) of the stifle joint associated with cranial cruciate ligament (CCL) rupture in dogs and assessing whether the surgical treatment carried out on the affected joints affected additional changes. A retrospective cohort study design was used. The clinical records of dogs treated with tibial tuberosity advancement (TTA), tibial plateau leveling osteotomy (TPLO) and tight rope (TR) were reviewed as were the extension angle (EA), flexion angle (FA) and lameness. The data recorded at T0, before surgery, were compared with the data at 1 month and 6 months post-surgery. The data were classified as normal or abnormal. The main results obtained one month after surgery indicated that dogs treated with TTA showed a significant worsening of flexion (the FA was abnormal in 69.6 % of dogs at T0 and 80.4 % at T1 with p = 0.0208). Dogs treated with TPLO achieved asignificant improvement in extension (the EA was normal in 16.7 % of dogs at T0 and in 33.3 % at T1 with p < 0.0001), and in flexion (the FA was normal in 23.8 % of dogs at T0 and 43.5 % at T6 with p = 0.0434). The dogs treated with TR showed a significant worsening of extension (the EA was abnormal in 68.8 % of dogs at T0 and in 81.3 % at T1 with p = 0.0024). Six months post-surgery, the ROM value was not normal in 100 % of the stifle joints; however, the lameness significantly improved with each procedure. This study confirmed the influence of surgical procedures on changes in ROM and provided useful indications for planning therapy to improve and speed up the postoperative rehabilitation process in dogs.
本研究旨在评估犬十字韧带（CCL）断裂后膝关节被动活动范围（ROM）的变化，并评估对受影响关节进行的手术治疗是否会导致额外的变化。采用回顾性队列研究设计。对接受胫骨结节移位术（TTA）、胫骨平台水平截骨术（TPLO）和紧绳术（TR）治疗的犬的临床记录进行了回顾，同时记录了伸展角（EA）、弯曲角（FA）和跛行。将手术前的 T0 时记录的数据与手术后 1 个月和 6 个月时的数据进行了比较。数据被分为正常或异常。手术后 1 个月的主要结果表明，接受 TTA 治疗的犬的弯曲明显恶化（T0 时 69.6%的犬 FA 异常，T1 时 80.4%的犬 FA 异常，p = 0.0208）。接受 TPLO 治疗的犬的伸展有显著改善（T0 时 16.7%的犬 EA 正常，T1 时 33.3%的犬 EA 正常，p < 0.0001），弯曲也有显著改善（T0 时 23.8%的犬 FA 正常，T6 时 43.5%的犬 FA 正常，p = 0.0434）。接受 TR 治疗的犬的伸展明显恶化（T0 时 68.8%的犬 EA 异常，T1 时 81.3%的犬 EA 异常，p = 0.0024）。手术后 6 个月，100%的膝关节 ROM 值仍不正常；然而，每种手术都能显著改善跛行。本研究证实了手术程序对 ROM 变化的影响，并为规划治疗提供了有用的指标，以改善和加快犬术后康复过程。
