The impact of reducing the femoral stem length in total hip arthroplasty during gait.
Arch Orthop Trauma Surg
November 2021
Aim: The length of the femoral stem in total hip arthroplasty (THA) is a practical consideration to prevent gait impairment. The aim of this study was to determine if reducing the femoral stem length in THA would lead to impaired gait biomechanics.
Methods: Patients uniformly with the same brand implant of differing lengths (100 mm vs 140-166 mm) were taken retrospectively from a prospective trial introducing a new short stem.
The unicompartmental knee is the preferred side in individuals with both a unicompartmental and total knee arthroplasty.

October 2020
Purpose: To determine the preferred knee in patients with both one total and one unicompartmental knee arthroplasty.
Method: Patients simply with a unicompartmental (UKA) and total knee arthroplasty (TKA) on contralateral sides were retrospectively screened from three senior knee surgeon's logs over a 15 year period. Patients safe and free from other diseases to affect gait were approached.
Origin and insertion of the medial patellofemoral ligament: a systematic review of anatomy.

Article Synopsis
- The medial patellofemoral ligament (MPFL) is crucial for knee stability, connecting the femur to the patella; understanding its anatomy is vital for surgical reconstruction.
- A systematic review of literature identified 67 studies that reveal the MPFL originates from a triangular area on the medial femoral condyle rather than a single point, with an average length of 56 mm and an hourglass shape.
- The conclusion emphasizes the importance of recognizing the MPFL's anatomy for effective diagnosis and surgical procedures aimed at stabilizing the patella.
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.
