Unicompartmental Knee Arthroplasty Enables Near Normal Gait at Higher Speeds, Unlike Total Knee Arthroplasty

Unicompartmental Knee Arthroplasty Enables Near Normal Gait at Higher Speeds, Unlike Total Knee Arthroplasty

Top walking speed (TWS) was used to compare UKA with TKA. Two groups of 23 patients, well matched for age, gender, height and weight and radiological severity were recruited based on high functional scores, more than twelve months post UKA or TKA. These were compared with 14 preop patients and 14 normal controls. Their gait was measured at increasing speeds on a treadmill instrumented with forc...

Unicompartmental Knee Arthroplasty

Unicompartmental knee arthroplasty

The unicompartmental knee arthroplasty is an interesting and potentially beneficial procedure that remains a controversial alternative to total knee arthroplasty and high tibial osteotomy. A critical review of the literature reveals inconsistent results using this compartmental approach to joint resurfacing. Many of the inconsistencies, however, are attributable to improper patient selection, p...

Unicompartmental Knee Osteoarthritis (UKOA): Unicompartmental Knee Arthroplasty (UKA) or High Tibial Osteotomy (HTO)?

  Background: The aim of this review article is to analyze the results of high tibial osteotomy compared to unicompartmental knee arthroplasty in patients with unicompartmental knee osteoarthritis.   Methods: The search engine used was PubMed. The keywords were: "high tibial osteotomy versus unicompartmental knee arthroplasty". Twenty-one articles were found on 28 February 2015, but only eighte...

Conversion of unicompartmental knee arthroplasty to total knee arthroplasty: the challenges and need for augments.

The potential advantages of unicompartmental knee arthroplasty (UKA) include lower morbidity and mortality, quicker recovery, good range of motion, good medium and long-term survival results, potential bone conservation and perceived easier revision. Converting a UKA to a total knee arthroplasty (TKA) may be challenging due to issues of bone loss, need for augmentation, restoring joint line and...
