Abstract

BACKGROUND: High physical activity (HPA) levels after total knee arthroplasty (TKA) might be related to increased wear and subsequent aseptic loosening, negatively affecting TKA survival. This systematic review studied the association between activity levels and risk of revision surgery at medium (3-10 years) and long term (>10 years) follow up in patients with TKA.

METHODS: Databases (PubMed, Embase) were searched up to 12 October 2021. Studies comparing low physical activity (LPA) and HPA levels in TKA patients and related risk of revision surgery were eligible for inclusion. After data extraction and evaluation of methodological quality, a meta-analysis was performed. Quality of evidence was assessed using the GRADE framework. PROSPERO registration: CRD42020194284.

RESULTS: Five cohort studies and one case-control study met the inclusion criteria, involving 4811 TKA procedures in 4263 patients (mean follow up 4-12 years). Five studies were of moderate methodological quality and one of low quality. Meta-analysis demonstrated no association between HPA level and an increased risk of all-cause revision surgery (risk ratio (RR) 0.62, 95 % confidence interval (CI) 0.24-1.63, level of certainty: very low) or revision surgery due to aseptic loosening (RR 1.33, 95 % CI 0.34-5.24, level of certainty: moderate). Only one study reported on survivorship, with an improved survivorship for the HPA group (odds ratio of 2.4, 95 % CI 1.2-4.7, level of certainty: low).

CONCLUSION: During the first 12 postoperative years after TKA, there seems to be no increased risk for revision surgery for patients with a HPA level compared with patients with an LPA level.
