High-flexion TKA Designs

Performing high flexion activities does not seem to be crucial in developing early femoral component loosening after high-flexion TKA

BACKGROUND It is still unclear whether high flexion (HF) activities correlated with the early loosening of the femoral component and whether HF activities are possible. We investigated what is the capability for performing various HF activities, and whether high flexion activities increase the chance of aseptic loosening after HF-TKA. METHODS We retrospectively analysed 260 patients who under...

Design modifications of high-flexion TKA do not improve short term clinical and radiographic outcomes

BACKGROUND The prosthesis of contemporary total knee arthroplasty (TKA) has been modified to provide a more familiar environment for higher flexion angle of the replaced knee. The design modifications continue based on evidence reported in the literature. However, whether these modifications of the prosthesis design lead to improvements in clinical results needs further investigation. We determ...

Title:design Modifications of High-flexion Tka Do Not Improve Short Term Clinical and Radiographic Outcomes

Outcome and range of motion using a high-flexion cruciate-retaining TKA.

Increased knee flexion after total knee arthroplasty (TKA) may contribute to patients' increased satisfaction and more active lifestyles. This study evaluated a TKA component designed for high flexion (more than 125°). The design features an anatomic sagittal femoral radius with short, flared femoral condyles to allow for femoral rollback. Fifty TKA procedures in 47 patients were evaluated pros...

Peak knee flexion angles during stair descent in TKA patients.

Reduced peak knee flexion during stair descent (PKSD) is demonstrated in subjects with total knee arthroplasty (TKA), but the underlying factors are not well studied. 3D gait patterns during stair descent, peak passive knee flexion (PPKF), quadriceps strength, pain, proprioception, demographics, and anthropometrics were assessed in 23 unilateral TKA-subjects ~19 months post-operatively, and in ...
