Hunt LP, Blom AW, Matharu GS, et al. - Researchers used National Joint Registry data to ascertain unicompartmental (UKR) as well as total knee replacement (TKR) revision rates, compared UKR revision rates with what they would have been had they underwent TKR instead, and evaluated subsequent re-revision as well as 90-day death rates. Findings revealed substantially higher UKR revision rates compared with TKR even when demographics as well as caseload variations were accounted for; however, the occurrence of fewer deaths was reported post-UKR. When planning treatment guidelines and commissioning services, this should be taken into account. Re-revision rates were shown to be similar between revised UKRs and TKRs, but were identified to be considerably higher than for primary TKR, thus, UKR cannot be regarded as an intermediate procedure.
