“…Data from 32 studies were available to compare mobile-bearing vs. fixed-bearing implants; 10 studies (n ¼ 2,268) with mobile-bearing implants [14,18,28,32,33,37,38,41,50,53], 18 studies (n ¼ 1,469) with fixed-bearing [8,26,[42][43][44][45][46][47][48][49]27,30,31,[34][35][36]39,40] and 4 additional studies that reported outcomes for both (n ¼ 1,743 mobile-bearing, n ¼ 790 fixed-bearing) [25,29,46,51]. 18 studies had a moderate risk of bias [8,18,[44][45][46][47][48][49][50]53,26,31,33,34,37,39,42,…”

“…However, with a small sample size in each subgroup, caution must be applied. Besides, recent reports on long-term survivorship included in this analysis 7,29 (with a mean follow-up of 9.1-14.8 years) might be affected by its enormous inclusion period (>20 years) and the collation of sometimes old data. The study of Murray et al 29 was considered a heterogeneity generator by sensitivity analysis.…”

“…A majority of included papers (85%) were Europebased, with 3 conducted in the USA and one in China. There were two registry-based studies 17,28 without providing surgical details; three papers 7,8,37 were multiple-centered and the remaining were single-institution studies. Regarding surgeries, most lateral UKAs were performed using the lateral approach and 702 lateral UKAs from 10 papers (38.5%) were performed by one surgeon.…”

“…5 Extensive literature is available regarding medial UKA, showing good survival outcomes. 6 Even though modern reports on lateral UKA have shown similar advantages with excellent survivorship, [7][8][9] the reliability of lateral UKA has yet to be elucidated. Due to the infrequency of this procedure, there remains a paucity of large studies evaluating lateral UKA alone.…”

Background: The infrequency of lateral unicompartmental knee arthroplasty (UKA) has led to a lack of understanding of its survival. This study aimed to systematically evaluate the survivorship results of lateral UKA at different follow-ups based on available literature. Methods: Five databases were searched for eligible studies. Pooled survivorships with 95% confidence intervals (CIs) at 3, 5, 10, 15, and 20 years after lateral UKA were estimated using a random-effect model. Subgroup and sensitivity analyses were performed. Results: A total of 26 studies involving 5470 lateral UKAs were included. Survivorships of lateral UKA at 3-, 5-, 10-, 15-, and 20-year follow-ups were 96% (95% CI: 95-98%, I 2 : 77.5%), 94% (95% CI: 93-96%, I 2 : 70.8%), 88% (95% CI: 84-91%, I 2 : 70.8%), 85% (95% CI: 79-91%, I 2 : 70.8%), and 78% (95% CI: 71-85%, I 2 : 54.2%), respectively. Subgroup analyses found that bearing type, the number of surgeons, and year of publication might be associated with implant survival outcomes. Conclusion: Lateral UKA is an effective procedure with excellent survivorships at short-, mid-, and long-term follow-ups. Results suggest a single-surgeon lateral UKA using fixedbearing. Additional well-designed studies are needed to elucidate the current findings.

“…For the analysis of survivorship, failure was de ned as revision for any reason (de ned as operations in which at least one of the components was changed), reoperations, aseptic revision and dislocation of the bearing. [12] Assessment of methodological quality As the previous systematic review mentioned, the quality of studies available was low. [13] Therefore, a quality assessment was conducted using the Newcastle-Ottawa Scale (NOS), which was accommodated to the studies included in this meta-analysis.…”

BackgroundThe effectiveness of unicompartmental knee arthroplasty by lateral UKA remains poorly characterized as a limit of lateral UKA were operated for osteoarthritis (OA). However, the field of UKA surgery has rapidly expanded the usage of partly knee replacement in KOA patients with increased satisfaction, survivorship and functional outcomes. Methods A meta-analysis was conducted to evaluate the survivorship of lateral UKA with assessment with short-to midterm (<10years) and long-term (>10years) follow-up. Five databases were searched for eligible studies with search terms modified to the instructions of different databases. Twenty-three studies met the inclusion criteria and the pooling data were summarized in forest plots.ResultsThe implant survivorship of lateral UKA in short-term (3 year) was 96% (95%CI, 0.95-0.97, P<0.001), mid-term (5 year) 95% (0.93-0.96, P<0.001), long-term (10 year) 89% (0.85-0.93, P<0.001), and 15 year (85.5%, 0.79-0.92, P<0.001). Sensitivity and subgroup analysis was conducted for potential source of heterogeneity. ConclusionLateral UKA is a promising method of 90% survivorship over a short- to long-term follow up. Lateral UKA is a viable option in primary treatment of OA.
