INTRODUCTION Isolated patellofemoral (PF) arthritis is rare, and there is no complete agreement about the best surgical treatment. The operative treatments are total knee arthroplasty and patellofemoral replacement (PFR). The incidence of many early complications of PF arthroplasty has decreased with the introduction of newer designs. Nowadays, the main cause of revision surgery is the progress...

The options for treatment of the young active patient with isolated symptomatic osteoarthritis of the medial compartment and pre-existing deficiency of the anterior cruciate ligament are limited. The potential longevity of the implant and levels of activity of the patient may preclude total knee replacement, and tibial osteotomy and unicompartmental knee arthroplasty are unreliable because of t...

INTRODUCTION The present case report describes a patient who presented with an early complication after a unicompartmental knee arthroplasty. It is not the first case in this subject but the unique aspect of this case report rests on the timing in which the failure occurred. CASE PRESENTATION A 64-year-old Caucasian man received a medial unicompartmental knee arthroplasty (Oxford® Partial Kne...

Popliteal vascular injury and the compartment syndrome of the leg are rare but important complications of knee arthroplasties. Early diagnosis and treatment are of paramount importance in preventing the devastating complications of these conditions. To our knowledge, these complications have not been reported previously after unicompartmental knee arthroplasty in the literature. Low level of su...

Isolated unicompartmental osteoarthritis in the young patient is a difficult problem to treat; they may be too young to consider total knee arthroplasty due to difficulties with inevitable future revision. Unicompartmental knee arthroplasty is one possible solution as it is perceived by some as being a smaller surgical insult than total knee arthroplasty, with easier revision to total knee arth...

OBJECTIVE The aim of this study was to evaluate the approaches and procedures used by Brazilian orthopedic surgeons for treating osteoarthrosis by means of unicompartmental knee arthroplasty and high tibial osteotomy of the knee. METHODS A questionnaire with 14 closed questions was developed and applied to Brazilian knee surgeons during the three days of the 43(rd) Brazilian Congress of Ortho...

The unicompartmental knee arthroplasty is an interesting and potentially beneficial procedure that remains a controversial alternative to total knee arthroplasty and high tibial osteotomy. A critical review of the literature reveals inconsistent results using this compartmental approach to joint resurfacing. Many of the inconsistencies, however, are attributable to improper patient selection, p...

Unicompartmental knee arthroplasty has been associated with faster recovery with less potential perioperative morbidity compared to total knee arthroplasty. This study investigates the rate of transfusion, symptomatic thromboembolic events, and length of hospital stay in 1000 consecutive, unicompartmental knee replacements performed by 2 surgeons. A rapid recovery protocol coupled with multimod...

BACKGROUND Knee arthritis in the young patient is a challenging problem that may necessitate surgical treatment. We continue to perform hemiarthroplasty with a metallic tibial implant in selected young patients who, for various reasons, are not candidates for osteotomy, unicompartmental arthroplasty, or total knee arthroplasty. The purpose of the present study was to determine the minimum twelv...
