Abstract
Objective: To investigate the effect of the flexion angle of a femoral prosthesis on the postoperative clinical outcome of patients with knee osteoarthritis who are undergoing unicompartmental knee arthroplasty.
Methods: Patients were divided into three groups according to the flexion angle of the femoral prosthesis following unicompartmental knee arthroplasty. Group A comprised patients with a flexion angle of the femur prosthesis of less than 5°, Group B included those with a flexion angle of 5° to 10°, and Group C consisted of patients with a flexion angle of the femur prosthesis greater than 10°. The basic clinical data, visual analog scale (VAS) score, Hospital for Special Surgery (HSS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and knee range of motion (ROM) were subjected to statistical analysis and comparison between the groups.
Results: No significant differences were observed in the basic data of the patients in each group. The ROM and VAS scores for the knee in the first month following unicompartmental knee arthroplasty in groups B and C were significantly greater than those in group A. The HSS scores for the knee joint in Group B indicated superior outcomes in the initial postoperative month and the third postoperative month, as evidenced by the WOMAC scores, which demonstrated a statistically significant difference between Group B and the other two groups within the six-month postoperative period.
Conclusion: The short-term recovery of patients in Group B was the fastest. These results provide a new reference for the installation of femoral prostheses in unicompartmental knee arthroplasty.
目的研究股骨假体的屈曲角度对膝关节骨性关节炎患者接受单间室膝关节置换术的术后临床效果的影响:根据单间室膝关节置换术后股骨假体的屈曲角度将患者分为三组。A组包括股骨假体屈曲角度小于5°的患者,B组包括股骨假体屈曲角度在5°至10°之间的患者,C组包括股骨假体屈曲角度大于10°的患者。对各组的基本临床数据、视觉模拟量表(VAS)评分、特殊外科医院(HSS)评分、西安大略和麦克马斯特大学骨关节炎指数(WOMAC)评分以及膝关节活动范围(ROM)进行统计分析和比较:各组患者的基本数据无明显差异。结果:各组患者的基本数据无明显差异,B 组和 C 组患者在单间室膝关节置换术后第一个月的膝关节活动度(ROM)和 VAS 评分明显高于 A 组:结论:B 组患者的短期恢复最快。结论:B组患者的短期恢复最快,这些结果为单间室膝关节置换术中股骨假体的安装提供了新的参考。
期刊介绍:
Journal of Orthopaedic Surgery and Research is an open access journal that encompasses all aspects of clinical and basic research studies related to musculoskeletal issues.
Orthopaedic research is conducted at clinical and basic science levels. With the advancement of new technologies and the increasing expectation and demand from doctors and patients, we are witnessing an enormous growth in clinical orthopaedic research, particularly in the fields of traumatology, spinal surgery, joint replacement, sports medicine, musculoskeletal tumour management, hand microsurgery, foot and ankle surgery, paediatric orthopaedic, and orthopaedic rehabilitation. The involvement of basic science ranges from molecular, cellular, structural and functional perspectives to tissue engineering, gait analysis, automation and robotic surgery. Implant and biomaterial designs are new disciplines that complement clinical applications.
JOSR encourages the publication of multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines, which will be the trend in the coming decades.
