“…Generally, more complication were noted after a valgus HTO with significant difference found between the two groups ( p < 0.001; OR = 3.08; 95% CI = 1.76, 5.39), reflecting results from seven studies [8, 9, 12, 15, 17, 19, 20] with 559 patients.…”

“…The inclusion criteria for the other studies were varied or unclear. Six papers [5, 12, 13, 15, 18, 20] reported the cohorts using the Ahlbäck OA score, and three papers [9, 17, 21] used the Kellgreen–Lawrence (K/L) score. All of the included studies described the type of procedure, except one [18] in the HTO group and three [8, 16, 18] in the UKA group.…”

“…The analysis of 10 studies [5, 8, 9, 11–15, 18, 20] yielded a statistically significant difference between HTO and UKA regarding excellent/good results ( p < 0.001; OR = 0.37; 95% CI = 0.24, 0.58; Fig. 4).…”

“…Among them, five studies [5, 12, 13, 15, 20] provided clear support for medial OA, specifically in cases of varus deformity; however, the difference was not significant ( p = 0.43; OR = 0.75; 95% CI = 0.37, 1.52). Moreover, the subgroup analysis for the HTO group included opening [14, 15, 20] and closing-wedge [5, 8, 9, 11–13] procedures; these yielded differing results, with p values of 0.49 and 0.01, respectively, compared to the UKA group.

Background: Debate remains whether high tibial osteotomy (HTO) or unicompartmental knee arthroplasty (UKA) is more beneficial for the treatment of unicompartmental knee osteoarthritis. The purpose of this study was to compare the functional results, knee scores, activity levels, and complications between the two procedures. Methods: We performed a systematic review of published literature from August 1982 through January 2017. Fifteen papers reporting three prospective randomized trials were subjected to a meta-analysis. Results: No significant difference between the two groups was noted with respect to free walking (velocity), knee score, deterioration of the contralateral or patellofemoral knee, or revision rate and total knee arthroplasty. However, UKA produced better outcomes compared to HTO in terms of the functional results, pain assessment, and complications, although patients who underwent HTO tended to have slightly better range of motion. Conclusions: Valgus HTO provides better physical activity for younger patients whereas UKA is more suitable for older patients due to shorter rehabilitation time and faster functional recovery. Although UKA patients tended to have improved overall long-term outcomes, which may be due to accurate indications and patient selection, both treatment options yielded pleasing results. Therefore, we are unable to conclude that either method is superior.

“…They found that the two procedures were reliable and effective for medial osteoarthritis of the knee and had similar reoperation rates; however, clinical outcomes of UKA was superior to those of HTO. Recently, Petersen and Metzlaff24) compared minimum 5 year follow-up results of the frequently used opening wedge HTO and mobile-bearing UKA performed in patients between 55 and 65 years of age. There was no significant difference in terms of reoperation rates; however, the incidence of residual pain and symptoms was higher after HTO, which they suggested patients should be informed of prior to surgery.…”

PurposeThe purpose of this study was to evaluate the efficacy of unicompartmental knee arthroplasty (UKA) in young active Asian patients by analyzing clinical outcomes, complications and survival rates.Materials and MethodsEighty-two knees were evaluated with a minimum follow-up of 5 years after Oxford phase 3 UKA in patients less than 60 years of age at the time of surgery. Their mean age was 54.7 years (range, 44 to 59 years). The mean follow-up period was 8.9 years (range, 5.3 to 12 years). Kaplan–Meier survivorship analysis was used to estimate implant survival.ResultsIncluding 3 bearing dislocations, 1 medial tibial collapse and 1 lateral osteoarthritis, the total complication rate was 6.1% (5/82). Of the 3 cases of bearing dislocation, 2 cases were resolved by replacing with a thicker bearing and 1 case was converted to total knee arthroplasty (TKA) due to repeated dislocation. The two knees with a medial tibial collapse and a lateral osteoarthritis were converted to TKA. The 10-year cumulative survival rate using Kaplan-Meier survival method was 94.7% (95% confidence interval: 88.7%–100%).ConclusionsOxford medial UKA was reliable and effective in young active Asian patients providing good clinical results and survival rate in the mid-term follow-up.

Open wedge high tibial osteotomy (HTO) versus mobile bearing unicondylar medial joint replacement: five years results

Abstract: The results of this study showed that 5 years after surgery patients after UKA had less residual pain and symptoms than patients after UKA. These advantages might result in a higher quality of life.
