Survivorship of UKA in the middle-aged

Accuracy of Individualized Custom Tibial Cutting Guides in UKA

“…When putting in the tibial tray, some surgeons recommend restoring the natural tibial varus of the tibial plateau [3,9]. Most other surgeons aim for a tibial component being perpendicular to the mechanical axis of the tibia [1].…”

“…Long-term survival of UKA in registries has, however, been reported to be inferior to that of total knee arthroplasty (TKA) [16,29]. Experience with UKA contributes tremendously to successful outcome of this procedure [9]. As indications for UKA are less common, this experience is relatively hard to achieve in the average orthopedic practice.…”

Preoperative pain location is a poor predictor of outcome after Oxford unicompartmental knee arthroplasty at 1 and 5 years

“…Kozinn and Scott [18] Bert [5] suggested that the ideal patient for UKA should be able to pinpoint their pain to the medial joint line (the 'one finger sign') rather than feeling pain generally within the knee (the 'knee grab sign'). Whilst no evidence-base exists to support this practice, it has been adopted by other authors as a prerequisite for UKA [10,14,27].…”

Better Quality of Life After Medial Versus Lateral Unicondylar Knee Arthroplasty

“…In that study, the cumulative survival rates for a lateral UKA were 83% at 10 years and 74% at 15 years. Some studies [17,36,40] analyzed lateral and medial UKAs with conflicting findings regarding risk of revisions. For example, in the earliest study [36], there was a survival of 83% at 3 1 .…”

“…In the most recent study [40], there were no revisions in 31 lateral UKAs, but six revisions in 147 medial UKAs, whereas another study [17] reported similar revision rates for medial and lateral UKAs. Of the studies evaluating health-related quality of life (HRQoL) outcomes such as the WOMAC TM [40], the Hospital for Special Surgery Score [30,32], or The Knee Society Score Ó [17,23,24], only one study [40] compared one of these HRQoL outcomes in medial versus lateral UKAs. That study did not describe a difference between medial and lateral UKAs regarding the specific HRQoL outcome (WOMAC).…”
