Background This study was designed to evaluate predictors of good outcomes following medial unicompartmental knee arthroplasty (UKA) in Asian patients. Methods Registry data of patients who underwent primary unilateral medial UKA from 2006 to 2011 were collected. Outcomes studied were the Oxford Knee Score (OKS) and the Physical Component Score (PCS) of the Short Form 36 (SF-36) questionnaire...
PURPOSE The purpose of the present study is to compare the prevalence of implant overhang between the Oxford and the Miller-Galante II (M-G II) unicompartmental knee arthroplasty (UKA) prostheses and determine whether overhang is associated with postoperative clinical results. MATERIALS AND METHODS We retrospectively reviewed one hundred and seven UKAs which consisted of 37 Oxford UKAs and 70...
Unicompartmental knee arthroplasty (UKA) is appropriate for one in four patients with osteoarthritic knees. This study was performed to compare the safety, effectiveness and economic viability of a new accelerated protocol with current standard care in a state healthcare system. A single blind RCT design was used. Eligible patients were screened for NSAID tolerance, social circumstances and geo...
One of the findings of prosthetic failure seen either on pre operative radiograph or at surgery is metallosis. To our knowledge, this has not been described in an apparently well-fixed noninfected prosthetic joint. Metallosis can be due to polyethylene bearing wear resulting in metal on metal wear and has been seen with macro motion of prosthesis against underlying cement or bone1. CASE REPORT ...
BACKGROUND Patellofemoral joint replacement is a successful treatment option for isolated patellofemoral osteoarthritis. However, results of later conversion to total knee replacement may be compromised by periprosthetic bone loss. Previous clinical studies have demonstrated a decrease in distal femoral bone mineral density after patellofemoral joint replacement. It is unclear whether this is d...
A 64-year-old man presented with a severe deformity of the tibia caused by Paget's disease and osteoarthritis of the ipsilateral knee. Total knee replacement required preliminary correction of the tibial deformity. This was successfully achieved by tibial osteotomy followed by distraction osteogenesis using the Taylor spatial frame. The subsequent knee replacement was successful, with no recurr...
Stiffness is an uncommon complication after total knee arthroplasty, but at the same time it is a disabling problem for many patients. Outcomes of revision surgery for a stiff knee following arthroplasty have not been well evaluated, to our knowledge. The purpose of this literature is to define prevalence of stiffness after primary total knee replacement and also to evaluate the efficacy of rev...
Knee osteoarthritis is associated with structural changes in the joint. Despite its many drawbacks, radiography is the current standard for evaluating joint structure in trials of potential disease-modifying osteoarthritis drugs. MRI is a non-invasive alternative that provides comprehensive imaging of the whole joint. Frequently used MRI measurements in knee osteoarthritis are cartilage volume ...
Total knee arthroplasty is one of the most common orthopaedic procedures performed. In 2001 171,335 primary knee replacements and 16,895 revisions were performed.1 Throughout this report we use the term total knee arthroplasty (TKA) in lieu of total knee replacement because the abbreviation for the latter may be readily confused with total knee revision. Because these procedures are elective an...
Many patients would like to resume some sport activities after total knee replacement; however, most recommendations are based on subjective opinion rather than scientific evidence. The following paper presents a literature review of sports after total knee replacement and includes recommendations which are based on biomechanical laws. Most total knee designs show increased conformity near full...
