“…The FJS in our UKA cohort was significantly higher than that reported in a cohort of TKA patients by Behrend et al [26], although still lower than their group of healthy controls (Table 3). Our findings coincide with those from Zuiderbaan et al [38], who found significantly higher FJS values in UKA patients (74.3 ± 24.8) than in TKA patients (59.8 ± 31.5), at a follow-up time of 2 years. Notably, patients with a BMI > 40 kg/m 2 had lower FJS scores in our series.…”

The current study was designed to determine (1) 10-year implant survival and (2) patient’s self-reported functional outcome in a single surgeon’s consecutive cohort of patients who had undergone minimally invasive unicondylar resurfacing with a modified cementation technique utilizing a cobalt–chromium femur/inlaid all-PE tibia, fixed-bearing unicompartmental prosthesis. We included 344 consecutive patients (361 knees) who had received the study device between January 2002 and December 2005 in this retrospective study. After 10 years, 78 patients (78 knees) had died, 59 (59 knees) were lost to follow-up and four (four knees) did not participate. Thirteen knees (11 patients) were revised after a mean of 5.8 ± 1.9 years. Hence, the study population at follow-up comprised 192 patients (207 knees). Ten-year implant survival was 94.6% (95% confidence interval, 90.9–96.8%). The Forgotten Joint Score and Oxford Knee Score were 68.9 ± 28.9 and 39 ± 9.1, respectively. Excellent survivorship and clinical outcomes were obtained with UKA with an inlaid all-PE tibia with a modified cementation technique.

“…Reported advantages include a less invasive approach with less bone resection, low complication rates, easier post‐operative rehabilitation, faster recovery, greater range of motion, and good long‐term survivorship. Patients who undergo UKA showed a superior functional outcome compared to TKA patients, and were more likely to forget their artificial joint in daily life. Good outcomes have been reported for the Oxford mobile‐bearing UKA in overweight, younger, and more active patients, as well as in the presence of co‐existent PFJ degeneration.…”

Predictors of Midterm Outcomes after Medial Unicompartmental Knee Arthroplasty in Asians

BackgroundThis study was designed to evaluate predictors of good outcomes following medial unicompartmental knee arthroplasty (UKA) in Asian patients.MethodsRegistry data of patients who underwent primary unilateral medial UKA from 2006 to 2011 were collected. Outcomes studied were the Oxford Knee Score (OKS) and the Physical Component Score (PCS) of the Short Form 36 (SF-36) questionnaire. These outcome scores were collected prospectively, pre- and postoperatively up to 5 years. Good outcome was defined as an overall improvement in score greater than or equal to the minimal clinically important difference (MCID). The MCID for the OKS was 5 while the MCID for the PCS was 10. Regression analysis was used to identify predictors of good outcomes following medial UKA.ResultsPrimary medial UKA was performed in 1,075 patients. Higher (poorer) preoperative OKS (odds ratio [OR], 1.27; p < 0.001), lower (poorer) preoperative PCS (OR, 1.08; p < 0.001), lower (poorer) preoperative Knee Society Knee Score (KSKS; OR, 1.02; p < 0.001) and higher (better) preoperative SF-36 Mental Component Score (MCS; OR, 1.02; p < 0.001) were significant predictors of good outcomes.ConclusionsPatients with poorer OKS, PCS and KSKS and better SF-36 MCS preoperatively tended to achieve good outcomes by the MCID criterion at 5 years following the index surgery.
