The aim of this study was to assess the influence of obesity on the clinical outcomes and survivorship ten years postoperatively in patients who underwent a fixed-bearing unicompartmental knee arthroplasty (UKA). We prospectively followed 184 patients who underwent UKA between 2003 and 2007 for a minimum of ten years. A total of 142 patients with preoperative body mass index (BMI) of < 30 kg/m2 were in the control group (32 male, 110 female) and 42 patients with BMI of ≥ 30 kg/m2 were in the obese group (five male, 37 female). Pre- and postoperative range of movement (ROM), Knee Society Score (KSS), Oxford Knee Score (OKS), 36-Item Short-Form Health Survey (SF-36), and survivorship were analyzed.Aims
Patients and Methods
Medial patellofemoral ligament (MPFL) reconstruction
is used to treat patellar instability and recurrent patellar dislocation.
Anatomical studies have found the MPFL to be a double-bundle structure.
We carried out a meta-analysis of studies reporting outcomes of
patellofemoral reconstruction using hamstring tendon autograft in
a double-bundle configuration and patellar fixation via mediolateral
patellar tunnels. A literature search was undertaken with no language restriction
in various databases from their year of inception to July 2012.
The primary outcome examined was the post-operative Kujala score.
We identified 320 MPFL reconstructions in nine relevant articles.
The combined mean post-operative Kujala score was 92.02 (standard
