To evaluate the short-term clinical outcomes, complications, hospitalization time, and readmission rate related to day-case opening wedge high tibial osteotomy (OWHTO) with intraosseous PEEK (polyether ether ketone) implant, in the treatment of knee osteoarthritis.
An observational study on patients treated with OWHTO using intraosseous PEEK implant was performed with a period of 12 months follow-up. Grade of Knee Injury and Osteoarthritis Outcome Score (KOOS) was assessed preoperatively, at 6 months, and at 12 months postoperatively. A simple test was used to analyze the outcomes. values <.05 were considered significant. Complications and revision surgeries were registered.
In the period from 2016 to 2017, a consecutive group of 40 patients (13 female, 27 male) with symptomatic medial knee osteoarthritis and varus malalignment were included in the study. The average age of the patients was 54.9 (± 7.6) years. In total, 30 (77%) patients met the criterion for minimal clinically important difference in KOOS scores. The KOOS symptoms improved from 58.1 ± 20 to 78.5 ± 16.5 ( < .0001), pain from 48.1 ± 18.2 to 78.6 ± 18.5 ( < .0001), activities of daily living from 59.0 ± 19.5 to 84.1 ± 15.2 ( < .0001), sport from 23.2 ± 17.6 to 55.6 ± 26.3 ( < .0001), and quality of life from 28.4 ± 12.8 to 61.5 ± 22.5 ( < .0001) at 1-year follow-up. The average hospitalization time at the Day Surgery Unit was 5.6 ± 0.7 hours, and 4 (10%) patients had to be readmitted to the hospital within 2 weeks postoperatively. The overall complication rate was 18%. Complications that required revision surgery were registered in 4 patients (10%), including 2 non-unions and 2 progressions of osteoarthritis.
The day-case OWHTO with intraosseous PEEK implant was a success in 77% of the cases. The results and complications were comparable with other published studies. Despite a short hospitalization time, the readmission rate was low.

评估日间手术开放楔形高位胫骨截骨术（OWHTO）联合骨内聚醚醚酮（PEEK）植入物治疗膝关节骨关节炎的短期临床疗效、并发症、住院时间和再入院率。
对接受OWHTO联合骨内PEEK植入物治疗的患者进行观察性研究，随访期为12个月。在术前、术后6个月和12个月评估膝关节损伤和骨关节炎疗效评分（KOOS）等级。采用简单检验分析结果。P值<.05被认为具有显著性。记录并发症和翻修手术情况。
在2016年至2017年期间，连续纳入40例有症状的膝关节内侧骨关节炎和内翻畸形患者（13例女性，27例男性）进行研究。患者的平均年龄为54.9（±7.6）岁。总共有30例（77%）患者的KOOS评分达到最小临床重要差异标准。在1年随访时，KOOS症状评分从58.1±20改善至78.5±16.5（P<.0001），疼痛评分从48.1±18.2改善至78.6±18.5（P<.0001），日常生活活动评分从59.0±19.5改善至84.1±15.2（P<.0001），运动评分从23.2±17.6改善至55.6±26.3（P<.0001），生活质量评分从28.4±12.8改善至61.5±22.5（P<.0001）。日间手术单元的平均住院时间为5.6±0.7小时，4例（10%）患者在术后2周内不得不再次入院。总体并发症发生率为18%。4例（10%）患者记录了需要翻修手术的并发症，包括2例骨不连和2例骨关节炎进展。
77%的病例中，日间手术OWHTO联合骨内PEEK植入物取得成功。结果和并发症与其他已发表的研究相当。尽管住院时间短，但再入院率较低。
