background: this is to assess one of the rare complications after total knee replacement and to assess risk factors of failure.methods: 11 patients with varus knee and an average age of 67 years underwent tka between 2005 and 2013. all patients returned with a sudden sharp knee pain, disability to walk and significant decrease in rom about 4 to 8 weeks after surgery. radiographic examination re...

Satisfactory selection criteria are essential for the successful outcome of unicompartmental knee arthroplasty (UCA). We report the frequency of revision of the Oxford medial unicompartmental arthroplasty in knees previously treated for anteromedial osteoarthritis by high tibial osteotomy (HTO). The combined results from three sources were used to allow statistical analysis of this uncommon sub...

The purpose of this study was to summarize the literature describing patient outcomes following unicompartmental and bicompartmental knee arthroplasty. Original studies were included in this meta-analysis if they enrolled 10 or more patients at the time of an initial knee arthroplasty and measured patient outcomes using a global knee rating scale. Forty-six studies on unicompartmental prosthese...

Background Knee malalignment and variations in foot posture and function affect the forces transmitted through the knee joint and are associated with knee pain and medial tibiofemoral cartilage damage [1]. However, it is unclear whether altered foot posture and function are a compensatory mechanism to accommodate knee malalignment. Therefore, this study investigated changes in foot posture and ...

AIMS Since redesign of the Oxford phase III mobile-bearing unicompartmental knee arthroplasty (UKA) femoral component to a twin-peg design, there has not been a direct comparison to total knee arthroplasty (TKA). Thus, we explored differences between the two cohorts. PATIENTS AND METHODS A total of 168 patients (201 knees) underwent medial UKA with the Oxford Partial Knee Twin-Peg. These pati...

Between 1989 and 1992 we had 102 knees suitable for unicompartmental knee replacement (UKR). They were randomised to receive either a St Georg Sled UKR or a Kinematic modular total knee replacement (TKR). The early results demonstrated that the UKR group had less complications and more rapid rehabilitation than the TKR group. At five years there were an equal number of failures in the two group...
