Objective To investigate the accuracy and clinical efficacy of 3D-printed patient-specific instruments (PSIs) in medial open-wedge high tibial osteotomy (MOWHTO) for the treatment of knee varus deformity and medial compartment osteoarthritis. Methods Clinical data of 69 patients with knee varus deformity and medial compartment ostecarthritis who underwent MOWHTO treatment in Department of Orthopedics, Fuyang People's Hospital Affiliated to Anhui Medical University from October 2017 to March 2021 were retrospectively analyzed. Patients were divided into two groups: 3D group using 3D-printed PSIs (n=37) and conventional group using standard procedures (n=32). The lateral hinge point error, medial osteotomy point error, osteotomy surface angle error, osteotomy depth error, intraoperative distraction angle, femoral tibial angle (FTA), proximal tibial medial angle (MPTA), knee rotation angle (KRA), posterior tibial slope (PTS), intraoperative weight-bearing line ratio (WBLR), and the last follow-up International Knee Documentation Committee (IKDC) score of the two groups were compared. The correlation between accuracy indicators and curative effect was analyzed using Spearman's rank correlation. Results The follow-up time for the 3D group was 19-26 months, averaging (21.1±3.6) months; for the conventional group, it was 14-26 months, averaging (23.6±1.6) months. No significant differences were found between the two groups in lateral hinge point error, osteotomy depth error, intraoperative distraction angle, and the FTA, MPTA, KRA, PTS, IKDC score at the last follow-up (P>0.05). However, the 3D group showed significantly lower errors in medial osteotomy point, osteotomy surface angle, and intraoperative WBLR compared with conventional group (P<0.05). Spearman analysis revealed no correlation between IKDC score and aforementioned accuracy indicators (lateral hinge point error, medial osteotomy point error, osteotomy surface angle error, osteotomy depth error, intraoperative distraction angle, and WBLR) at the last follow-up (P>0.05). Conclusions The use of 3D-printed PSIs in MOWHTO offers a more precise advantage in certain positioning parameters, yet there are still deficiencies in determining WBLR. Compared to traditional MOWHTO surgery, the short-term outcome does not show any significant improvement.

3D打印个体化导板辅助下胫骨高位截骨的精准度及临床疗效分析, columnId=1190310109164180259, journalTitle=解放军医学杂志, columnName=临床研究, runingTitle=null, highlight=null, articleAbstract=
目的 探讨3D打印个体化辅助导板(PSI)辅助内侧开放胫骨高位楔形截骨术(MOWHTO)治疗膝关节内翻伴内侧间室骨关节炎的精准度及临床疗效。方法 回顾性分析2017年10月-2021年3月于安徽医科大学附属阜阳市人民医院骨科行MOWHTO治疗的69例膝关节内翻伴内侧间室骨关节炎患者的临床资料。根据术中治疗方法的不同将患者分为3D组(n=37,采用3D打印PSI辅助治疗)与常规组(n=32,采用标准流程进行治疗)。比较两组患者的外侧合页点误差、内侧截骨点误差、截骨面角度误差、截骨深度误差、术中撑开角度、股骨胫骨角(FTA)、胫骨近端内侧角(MPTA)、膝关节旋转角度(KRA)、胫骨后倾角(PTS)、术中负重线比率(WBLR)、末次随访国际膝关节文献委员会(IKDC)评分,并采用Spearman分析精准度相关指标与疗效的相关性。结果 3D组随访时间为19~26(21.1±3.6)个月,常规组为14~26(23.6±1.6)个月。两组外侧合页点误差、截骨深度误差、术中撑开角度,以及末次随访时FTA、MPTA、KRA、PTS、IKDC评分比较,差异均无统计学意义(P>0.05);3D组内侧截骨点误差、截骨面角度误差、术中WBLR明显低于常规组,差异有统计学意义(P<0.05)。Spearman分析结果显示,末次随访时IKDC评分与外侧合页点误差、内侧截骨点误差、截骨面角度误差、截骨深度误差、术中撑开角度、术中WBLR均无相关性(P>0.05)。结论 MOWHTO手术中应用3D打印PSI辅助可提高部分定位参数的精准度,但对于WBLR的确定仍存在一些不足,与传统的MOWHTO手术相比短期疗效并未提高。
