Intra-Articular Hyaluronic Acid Injections Less Than 6 Months Before Total Hip Arthroplasty: Is It Safe? A Retrospective Cohort Study in 565 Patients.

Background: Intra-articular hyaluronic acid (IAHA) can be injected into an osteoarthritic hip joint to reduce pain and to improve functionality. Several studies report IAHA to be safe, with minor adverse effects that normally disappear spontaneously within a week. However, intra-articular corticosteroids prior to total hip arthroplasty (THA) have been associated with increased infection rates.

Comparison of surgical treatments for mucous cysts of the distal interphalangeal joint.

Mucous cysts of the interphalangeal joints are common. Several surgical techniques have been described, but none has proven to be superior. We compared three techniques that entail complete removal of the cyst together with the concomitant osteophytes.

Pinnacle revision cup in acetabular surgery results at 2 to 5 years.

Uncemented revision cups are widely used in revision hip arthroplasty; they have shown good results. We report the the short term outcome with the cementless Pinnacle revision cup. All acetabular revisions using a Pinnacle revision cup between January 2007 and March 2010 were included.

Long-term outcome of elbow resurfacing.

Background: The purpose of this study is to review the long term results the Kudo and instrumented Bone Preserving elbow prostheses. The instrumented Bone Preserving prosthesis is the successor of the Kudo prosthesis, and both of these are nonconstrained elbow resurfacing prostheses.

Methods: Fifty-five nonconstrained elbow prosthesis were implanted in 51 patients.

Two-stage revision of an infected total hip arthroplasty: a follow-up of 136 patients.

Background And Purpose: Periprosthetic infection of a total hip arthroplasty (THA) is commonly treated with a two-stage revision procedure. After resection of the infected THA and placement of a cement spacer loaded with antibiotics, a THA is inserted at a second procedure to restore hip function and mobility. Revision surgery carries a significant risk of complications.

Outcome of custom-made IMP femoral components of total hip arthroplasty: a follow-up of 15 to 22 years.

A total of 1659 primary THAs using a cemented custom-made intra-operative manufactured prosthesis (IMP)-stem were studied. The end point for survival was defined as revision of the stem for any reason. Revision arthroplasty was performed in 49 cases.
