This prospective study evaluated the effect of tibial tuberosity advancement (TTA) on lameness, thigh circumference, range of motion (ROM), and radiographic osteoarthritis (OA) scores at 6 wk, 6 mo, and 1 y after surgery in 24 client-owned dogs with cranial cruciate ligament (CrCL) deficiency. Complications associated with TTA were also assessed. A significant improvement in lameness score and thigh circumference was observed in CrCL deficient limbs that received TTA, but no significant overall change in range of motion occurred in the affected limbs over the course of the study. Post-operative complications were identified in 33.3% of the dogs. This study demonstrates that TTA results in significant clinical improvement in patients up to 1 y after surgery. However, 21% of the dogs had post-operative recurrent lameness.
这项前瞻性研究评估了胫骨结节前移术（TTA）对24只患有前交叉韧带（CrCL）缺陷的宠物犬术后6周、6个月和1年时的跛行、大腿周长、活动范围（ROM）以及影像学骨关节炎（OA）评分的影响。同时也评估了与TTA相关的并发症。接受TTA的CrCL缺陷肢体的跛行评分和大腿周长有显著改善，但在研究过程中，受影响肢体的活动范围没有明显的总体变化。33.3%的犬出现了术后并发症。这项研究表明，TTA在术后长达1年的时间里能使患者在临床上有显著改善。然而，21%的犬术后出现复发性跛行。
