PURPOSE To analyze the current practice patterns of non-arthroplasty treatment of knee osteoarthritis (OA) and to assess the impact of the American Academy of Orthopaedic Surgeons clinical practice guidelines on the management of OA of the knee, particularly as they relate to the use of arthroscopic treatment. METHODS The United Healthcare Database (2004-2009, 11 million patients, 216 million...

The management of the stiff knee after total knee arthroplasty is controversial. Manipulation under anesthesia and open lysis of adhesions are techniques that can theoretically address the fibrous scar tissue, but their efficacy has been shown to be variable. We describe the technique of arthroscopic lysis of adhesions for the stiff knee after total knee arthroplasty. The advantages of this tec...

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...

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...

Dislocation after total knee arthroplasty is a difficult problem and is even more challenging if it occurs following revision. We report the case of a 82 year old male presenting after a frank posterior dislocation (Cam Jump) in a posterior stabilized revision knee arthroplasty without trauma. Flexion space instability with extensor insufficiency was presumed to be the cause of the dislocation ...

Infection is a serious complication after implantation of total knee-prostheses. However, fungal infection is rarely found in periprosthetic joints, and in most reports, the infecting organism is a Candida species. This is a case report of infection after left knee total arthroplasty caused by Malassezia species. The patient is still undergoing antifungal therapy with voriconazole and is still ...

BACKGROUND Cardiac complications are a major cause of postoperative morbidity. The purpose of this study was to determine the rates, risk factors, and time of occurrence for cardiac complications within thirty days after primary unilateral total knee arthroplasty and total hip arthroplasty. METHODS The American College of Surgeons National Surgical Quality Improvement Program data set from 20...

BACKGROUND Total joint arthroplasty is a highly efficacious and cost-effective procedure for moderate to severe arthritis in the hip and knee. Although patient characteristics are considered to be important determinants of who receives total joint arthroplasty, no systematic review has addressed how they affect the outcomes of total joint arthroplasty. This study addresses how patient character...

Background: Blood loss during and immediately after total knee arthroplasty (TKA) is among the most challenging concerns. It has been demonstrated that Tranexamic acid (TXA) can help to reduce perioperative blood loss. TXA can be used as an oral, topical or intravenous injection. Many studies evaluated the effectiveness of each route of administration but few works on a comparison between them....
