The purpose of this study was to summarize the literature describing patient outcomes following unicompartmental and bicompartmental knee arthroplasty. Original studies were included in this meta-analysis if they enrolled 10 or more patients at the time of an initial knee arthroplasty and measured patient outcomes using a global knee rating scale. Forty-six studies on unicompartmental prosthese...

Unicompartmental Knee Arthroplasty (UKA) is an established procedure for the treatment of unicompartmental arthritis. Success depends on a clear understanding of the principles and kinematics of the knee. Restoration of the physiological axis and soft tissue balancing is the key to a successful outcome. We outline the basic principles of UKA and the role of computer assisted surgery in achievin...

OBJECTIVE To investigate the role of early initiation of rehabilitation on length of stay (LOS) and cost following total hip arthroplasty, total knee arthroplasty, or unicompartmental knee arthroplasty. DATA SOURCES Electronic databases PubMed, CINAHL, Pedro, Embase, AMED, and the Cochrane Library were searched in July 2016. Five additional trials were identified through reference list scanni...

Twenty patients underwent simultaneous bilateral medial unicompartmental knee arthroplasty. Pre-operative hip-knee-ankle alignment and valgus stress radiographs were used to plan the desired post-operative alignment of the limb in accordance with established principles for unicompartmental arthroplasty. In each patient the planned alignment was the same for both knees. Overall, the mean planned...

Improved prosthetic design and application of strict criteria in selection of patients have resulted in wide use of unicompartmental knee arthroplasty (UKA) in surgical treatment of damaged joints. Here, we review the contemporary indications, outcomes, and complications of procedures such as lateral and medial UKA and total knee arthroplasty (TKA), and compare the severity of these complicatio...

PURPOSE Younger patients with unicompartmental degenerative knee joint diseases present a therapeutic dilemma. The purpose of this study is to evaluate the long-term results of the Oxford phase III unicompartmental knee replacement through a minimally invasive approach in the young patient. METHODS We have studied a total of 51 patients (59 interventions) who underwent the Oxford Phase III Un...

Methods: In a prospective study of 513 consecutive potential knee replacement candidates, 59 patients (12%) underwent medial unicompartmental arthroplasty of the knee. All 59 patients had isolated unicompartmental disease without either clinical symptoms or radiographic evidence of patellofemoral arthritis; intraoperatively no patient had more than Outerbridge class 2 chondromalacia. No patient...

Between 1986 and 1991, 106 patients (127 knees) underwent uncemented knee arthroplasty for osteoarthritis. There were 106 total knee arthroplasties and 21 medial unicompartmental knee arthroplasties. The arthroplasties were evaluated for aseptic loosening during the year 2000. For total arthroplasty we used 77 porous-coated anatomic prostheses and 29 press-fit condylar prostheses. The mean bone...

We present a comparison of the results of the Oxford unicompartmental knee arthroplasty in patients younger and older than 60 years of age. The ten-year all-cause survival of the < 60 years of age group (52) was 91% (95% confidence interval (CI) 12), while in the > or = 60 years of age group (512), the figure was 96% (95% CI 3). For the younger group, the mean Hospital for Special Surgery score...
