Prior Knee Arthroscopy Does Not Influence Long-Term Total Knee Arthroplasty Outcomes and Survivorship

Résumé : BACKGROUND: Arthroscopic knee surgery frequently precedes total knee arthroplasty (TKA). There have been mixed data on the effect of prior arthroscopic surgery on results of TKA. The purpose of this study was to compare the 10-year Knee Society Score (KSS), survivorship, and complications of TKA in a cohort of patients who had a previous knee arthroscopy to a control cohort. METHODS: A retrospective review of 1315 TKAs who underwent a primary TKA between 2003 and 2004 was performed. Of these, 160 TKAs had previous arthroscopy (excluding ligamentous reconstruction). A matched cohort study 2:1 was carried out with a group of 320 controls (no prior surgery). Outcomes were assessed with the original KSS, range-of-motion, complications, and survivorships. Mean follow-up was 9 years. RESULTS: The mean KSS increased from 36-84 in the arthroscopy group vs 35-86 in the control group (P = .5). The mean preoperative and postoperative range-of-motion was not different between groups (P = .2). The survivorship free of complication at 5 years was similar in both groups (94.3% in arthroscopy group vs. 95.3% in the control; P = .7) with infection in 2 controls and 3 arthroscopy cases (P = .2). The survivorships free of revision for aseptic loosening, revision for any reason, and reoperation were similar at 10 years (96.5%, 94.6%, and 89.2%, respectively, in the arthroscopy group vs 96.2%, 95.9%, and 91.5% in the control group). CONCLUSION: There were no significant differences between both groups. These data are reassuring and valuable in an era in which many candidates for TKA will have had previous arthroscopic knee surgery.
