Abstract

Purpose: Total knee arthroplasty (TKA) is an effective procedure for pain relief and restoration of function in patients with symptomatic end-stage knee arthritis. Kinematic problems due to conventional implant design have been postulated. The objective of this study is to determine if there was any difference in postoperative ROM and outcomes between patients undergoing MP-TKA vs PS-TKA.

Methods: We prospectively colected the records of 600 consecutive patients with TKA performed by six senior orthopaedic surgeons between 2017 - 2021. We compared the ROM and patient-reported outcomes (Western Ontario McMaster Osteoarthritis Index WOMAC, Oxford Knee Score OKS, Knee Society Score KSS, Forgotten Joint Score FJS) between MP TKA and PS TKA.

Results: There were no specific criteria for implant selection as the two groups were consecutive cohorts of patients and implant selection depended on surgeon preference. Demographics, comorbidities, diagnosis and severity of osteoarthritis were similar between MP and PS groups. The trend for OKS in our study is the same in both groups, but with higher mean values in the MP group. The trend of WOMAC pain, stiffness and disability score is the same in both groups, but with higher mean values in the PS group at one year and two years. KSS clinical and functional score is the same in both groups, but with higher mean values in the MP group. The most important score is forgetten joint score which is favourable for the MP group.

Conclusion: The patients who underwent the MP-TKA scored better than those who underwent the PS-TKA, particularly regarding deep knee flexion and stability of the prosthesis. This may be related to better replication of natural knee kinematics with MP-TKA.

全膝关节置换术的比较研究:内侧支点假体与后部稳定假体。前瞻性随机对照。
目的:全膝关节置换术(TKA)是缓解症状性终末期膝关节关节炎患者疼痛和功能恢复的有效方法。由于传统的种植体设计的运动学问题已经假定。本研究的目的是确定MP-TKA与PS-TKA患者术后ROM和预后是否存在差异。方法:我们前瞻性地收集了6名高级骨科医生在2017 - 2021年间连续实施的600例TKA患者的记录。我们比较了MP TKA和PS TKA之间的ROM和患者报告的结果(安大略省西部麦克马斯特骨关节炎指数WOMAC,牛津膝关节评分OKS,膝关节社会评分KSS,遗忘关节评分FJS)。结果:由于两组患者为连续队列,种植体的选择取决于外科医生的偏好,因此没有特定的种植体选择标准。统计学、合并症、诊断和骨关节炎严重程度在MP组和PS组之间相似。在我们的研究中,两组的OKS趋势相同,但MP组的平均值更高。两组的WOMAC疼痛、僵硬和失能评分趋势相同,但PS组1年和2年的平均值较高。两组的KSS临床和功能评分相同,但MP组的平均值更高。最重要的分数是遗忘关节分数,这对MP组有利。结论:MP-TKA患者的评分优于PS-TKA患者,特别是在膝关节深度屈曲和假体稳定性方面。这可能与MP-TKA更好地复制自然膝关节运动学有关。

期刊介绍: International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters. Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
