Factors contributing to instability after primary total knee arthroplasty: a twenty five Year retrospective cohort study.
Background: Total knee arthroplasty (TKA) is a highly effective procedure for end-stage knee osteoarthritis, but postoperative instability remains a major concern, impacting patient satisfaction and leading to potential revision surgeries. Understanding patient-related risk factors for instability is crucial for optimizing outcomes and minimizing complications.
Methods: We conducted a retrospective cohort study of patients who underwent revision TKA at our clinic between 1996 and 2021, focusing on those who required revision specifically due to instability. We analyzed a dataset of 39,572 primary TKA patients without documented revisions and 859 revision patients. Data extraction included age, gender, body mass index (BMI), age-adjusted Charlson Comorbidity Index (CCI) score, and comorbidities. Statistical analyses, including binary logistic regression, were performed to identify independent risk factors for instability.
Results: The instability group (n = 859) had a mean age of 65.7 years and a significantly lower proportion of males compared to the control group (mean age 67.5 years, p < 0.001; males 30.7% vs. 38.1%, p < 0.001). Notable risk factors included younger age, female gender, stroke, deep vein thrombosis (DVT), and scleroderma. Specifically, scleroderma was associated with a high risk of instability (P < 0.01 OR [odds ratio] 9.27, CI [confidence interval] 2.01 to 42.7), stroke (P = 0.01 OR 1.8, CI: 1.1 to 3.1), and DVT (p < 0.01 OR: 2.0, CI: 1.4 to 2.8).
Conclusion: Patient-related factors such as younger age, female gender, stroke, DVT, and scleroderma significantly influence the risk of instability following primary TKA. These findings highlight the multifactorial nature of TKA instability and underscore the importance of tailored preoperative assessment and postoperative care. Addressing these risk factors can improve patient outcomes and reduce the incidence of instability following TKA.
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.
