The purpose of this study was to evaluate short-term complications associated with the tibial plateau leveling osteotomy (TPLO) procedure in dogs of small and medium sizes. These study findings could then be compared with similar studies in dogs of all sizes. Ninety-eight procedures (82 dogs) using 2 or 2.7 mm TPLO plates were included spanning a 6 yr period with a minimum of an 8 wk follow-up period. The overall complication rate was 36%. Complications were grouped into three categories: intraoperative (2%), those occurring up to 2 wk postoperatively (11%), and those occurring >2 wk postoperatively (30%). Radiographic evidence of delayed healing of the TPLO osteotomy site was the most common complication in the dogs (9%), none of which had clinical signs attributed to delayed healing. Other common complications included patellar tendon thickening (8%) and tibial tuberosity fracture (6%). Seven percent of the complications were considered major (requiring additional surgical intervention). Fifty-two percent of complications did not require treatment. Short-term complications should not dissuade an experienced surgeon from performing the TPLO procedure in small- and medium-sized dogs.
本研究的目的是评估中小型犬胫骨平台水平截骨术（TPLO）相关的短期并发症。然后将这些研究结果与所有体型犬的类似研究进行比较。本研究纳入了98例使用2或2.7毫米TPLO钢板的手术（涉及82只犬），时间跨度为6年，随访期至少8周。总体并发症发生率为36%。并发症分为三类：术中并发症（2%）、术后2周内出现的并发症（11%）以及术后2周后出现的并发症（30%）。TPLO截骨部位延迟愈合的影像学证据是犬中最常见的并发症（9%），其中没有一只犬出现与延迟愈合相关的临床症状。其他常见并发症包括髌腱增厚（8%）和胫骨结节骨折（6%）。7%的并发症被认为是严重的（需要额外的手术干预）。52%的并发症无需治疗。短期并发症不应阻止经验丰富的外科医生对中小型犬实施TPLO手术。
