Treating isolated medial compartment knee osteoarthritis using Uni-compartmental Knee Arthroplasty (U.K.A)

Abstract

The Aim of this work is to provide cumulative data about the efficacy and safety of Unicompartmental knee arthroplasty (UKA) in treating isolated medial compartment knee osteoarthritis.

The average age of all patients was (69.1 ± 2.8 years); with youngest mean age of 65 years in Blaney et al, 2017 study; and oldest mean age of 74.1 years in Ventura et al, 2017 study.

The random-effects model of the meta-analysis study showed highly significant increase in mean functional knee score in Post-operative period (p < 0.0001).

The fixed-effects model of the meta-analysis study showed highly significant decrease in post-operative pain prevalence (p < 0.0001).

I2 (inconsistency) was 86%; with highly significant Q test for heterogeneity (p < 0.0001); so random-effects model was chosen to assess prevalence; with overall (post-operative pain prevalence) = 14.2% and a 95% CI ranged from 7.754 to 22.155.

I2 (inconsistency) was 97.7%; with highly significant Q test for heterogeneity (p < 0.0001); so random-effects model was chosen to assess rate; with overall (complications rate) = 18.3% and a 95% CI ranged from 8.607 to 30.756.

I2 (inconsistency) was 90.5%; with highly significant Q test for heterogeneity (p < 0.0001); so random-effects model was chosen to assess rate; with overall (failure or revision rate) = 7.1% and a 95% CI ranged from 3.797 to 11.338.
