摘　　要：目的分析CT三维重建技术在提高全膝关节置换术(TKA)精度和疗效中的应用价值。方法选取2022年1月~2023年12月河北省沧州中西医结合医院收治的KOA96例,回顾性分析入组者临床资料,均行TKA治疗。根据术前采用不同规划截骨方案分为对照和研究两组,对照组40例术前采用的是X线平片方案,研究组56例采用CT三维重建方案,对比两组围术期指标、下肢力线角、膝关节功能及手术优良率。结果研究组的手术时间较对照组更短,术中出血量少于对照组(P<0.05);研究组术后下肢力线角较对照组更高(P<0.05);研究组术后3个月、6个月HSS评分较对照组更高(P<0.05);研究组手术优良率为94.65%,高于对照组75.00%(P<0.05)。结论CT三维重建技术用于TKA中,相较于X平片,截骨方案制定更优,有利于缩短手术时间,提高手术优良率,并促进患者膝关节功能改善。Objective To analyze the application value of CT three-dimensional reconstruction technology in improving the accuracy and efficacy of total knee arthroplasty(TKA).MethodsNinety-six cases of knee osteoarthritis(KOA)treated at the Cangzhou Integrated Traditional Chinese and Western Medicine Hospital in Hebei Province from January 2022 to December 2023 were selected.Clinical data of the enrolled patients,who all underwent TKA treatment,were retrospectively analyzed.based on different preoperative bone cutting plans,the patients were divided into a control group and a study group.The control group(40 cases)received X-ray plain film for preoperative planning,while the study group(56 cases)received CT three-dimensional reconstruction.The perioperative indicators,lower limb alignment angle,knee joint function,and surgical success rate were compared between the two groups.ResultsThe study group had a shorter surgical time and less intraoperative bleeding compared to the control group(P<0.05).The study group also showed a higher postoperative lower limb alignment angle compared to the control group(P<0.05).Additionally,the study group had higher HSS scores at 3 and 6 months postoperatively compared to the control group(P<0.05).The surgical success rate in the study group was 94.65%,higher than 75.00%in the control group(P<0.05).ConclusionThe application of CT three-dimensional reconstruction technology in TKA provides a superior bone cutting plan compared to X-ray plain films.It helps shorten surgical time,improves the surgical success rate,and enhances knee joint function recovery in patients.
