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
This study investigated the influence of body mass index (BMI)
on patients’ function and quality of life ten years after total
knee arthroplasty (TKA). A total of 126 patients who underwent unilateral TKA in 2006
were prospectively included in this retrospective study. They were
categorized into two groups based on BMI: < 30 kg/m2 (control)
and ≥ 30 kg/m2 (obese). Functional outcome was assessed
using the Knee Society Function Score (KSFS), Knee Society Knee
Score (KSKS), and Oxford Knee Score (OKS). Quality of life was assessed
using the Physical (PCS) and Mental Component Scores (MCS) of the 36-Item
Short-Form Health Survey.Aims
Patients and Methods
Patellofemoral complications are common after
total knee replacement (TKR). Leaving the patellar unsurfaced after
TKR may lead to complications such as anterior knee pain, and re-operation
to surface it. Complications after patellar resurfacing include
patellar fracture, aseptic loosening, patellar instability, polyethylene
wear, patellar clunk and osteonecrosis. Historically, patellar complications
account for one of the larger proportions of causes of failure in
TKR, however, with contemporary implant designs, complication rates
have decreased. Most remaining failures relate to patellofemoral
tracking. Understanding the causes of patellofemoral maltracking
is essential to prevent these complications as well as manage them
when they occur. Cite this article:
