Factors influencing length of stay following primary total knee replacement in a UK specialist orthopaedic centre.

Aim: To identify factors significant in influencing LOS following primary TKA in a UK specialist arthroplasty centre.

Method: We retrospectively reviewed factors affecting LOS of 514 patients who underwent primary TKA in a single specialist arthroplasty centre in the UK over a one-year period. Surgical and patient factors that may influence LOS were recorded.

Alteration in skin sensation following knee arthroplasty and its impact on kneeling ability: a comparison of three common surgical incisions.

Purpose: Disturbance in skin sensation is a recognised, often unpleasant consequence of knee replacement for many patients and may affect function especially kneeling. The aim of this study was to compare post-operative changes in skin sensation following total (TKA) and unicompartmental knee (UKA) arthroplasties using three different incision types and its effect on kneeling ability.

Methods: Skin sensation was recorded using a purpose-designed grid over the front of the knee in 72 patients (78 knees) following knee arthroplasty.
