Patient-reported dissatisfaction following second side in staged bilateral total knee arthroplasty: A systematic review

Abstract

BACKGROUND Around one third of patients who undergo total knee arthroplasty (TKA) will eventually have the contralateral knee replaced. Overall patient satisfaction after staged bilateral total knee arthroplasty procedures performed on different days is reportedly similar to unilateral TKA. Nevertheless, in our anecdotal experience patients often report less satisfying outcomes following the second side. A cursory review of available literature tended to confirm that observation. We sought therefore to consolidate all of the available data on this issue to further investigate this phenomenon. AIM To consolidate available published data revealing satisfaction scores among patients following staged bilateral TKA, and to evaluate the phenomenon of less satisfying results following TKA2. METHODS A systematic review of available literature reporting on satisfaction with TKA1 and TKA2 after staged bilateral knee arthroplasty was undertaken using PubMed, Google Scholar, and Embase. From 427 records, five full-length articles met criteria for inclusion in the meta-analysis. The data were then extracted and assessed on the basis of the Reference Citation Analysis ( ). RESULTS A total of 1889 patients with an average age of 68 (range: 38–92) underwent staged bilateral TKA with outcomes reported at 1 year following each TKA with a mean 21.9 mo between surgeries (range: 2 d to 14.5 years). Overall satisfaction with both knees was 83.70% (1581) and dissatisfaction with both knees was 2.75% (52). In the remaining 13.56% (256) who were dissatisfied with one side, 61.0% were dissatisfied with TKA2, and 39.0% were dissatisfied with TKA1. Patient-reported outcome scores for TKA2 were frequently lower than TKA1 even in patients reporting overall satisfaction with both knees. CONCLUSION At 1-year follow-up, there was a 50% greater risk of dissatisfaction with TKA2 among the 13.56% of patients reporting dissatisfaction in one knee after staged bilateral TKA. Whether the interval between procedures or long-term follow-up changes these results requires further investigation.

Subsequent total joint arthroplasty: Are we learning from the first stage?

“…This seems to be particularly key in TKA. Multiple reviews have shown that the second TKA has significantly worse PROMs than the first[ 40 , 41 ] even in patients who were satisfied overall, and in patients who reported dissatisfaction with one of their TKAs, there was 50% greater risk of dissatisfaction at 1 year with the second TKA. However, from an objective surgical course and recovery perspective, our study demonstrates that operative time for THA, LOS, and postoperative discharge disposition can be anticipated for patients undergoing the second side TJA.…”
