Clinical outcomes of primary total hip arthroplasty with PMPC-grafted highly cross-linked polyethylene liners

Wear Analysis of Second-generation Highly Cross-Linked Polyethylene in Primary Total Hip Arthroplasty.

A major limiting factor in the longevity of total hip replacement is the wear rate of the hip bearing. As manufacturing technology has improved during the past several decades, much attention has been focused on developing newer generations of polyethylene that have lower rates of wear while minimizing free radical formation and subsequent osteolysis. The turning point for the manufacture of po...

Clinical Outcomes of Total Hip Arthroplasty in Patients with Ankylosed Hip

Background:   Various drugs are administered intra-articularly to provide postoperative analgesia after arthroscopic knee surgery. The purpose of this study was to assess the analgesic effects of intra-articular injection of a dexmedetomidine   following knee arthroscopy.     Methods:   Forty six patients schadualed for arthroscopic knee surgery under general anaesthesia, were randomly devided ...

Total Hip Arthroplasty Using Metal Head on a Highly Cross-linked Polyethylene Liner

PURPOSE This retrospective study was performed to evaluate the clinical results and measure polyethylene liner wear in total hip arthroplasty (THA) with highly cross-linked polyethylene. MATERIALS AND METHODS Except for patients who had died or were unable to have follow-up at least 2 years, 60 of 78 hips that underwent THA were included this study. The mean age was 64.5 years (range, 25-81 y...

Acetabular Liner for Total Hip Arthroplasty at Five Years Clinical Performance of a Durasul Highly Cross-Linked Polyethylene

Five-Year Experience of Vitamin E-Diffused Highly Cross-Linked Polyethylene Wear in Total Hip Arthroplasty Assessed by Radiostereometric Analysis.

BACKGROUND Vitamin E-diffused highly cross-linked polyethylene (VEPE) was developed to reduce oxidation without compromising mechanical strength. The purpose of this study was to evaluate VEPE in vivo using radiostereometric analysis (RSA) and patient-reported outcome measures (PROMs). METHODS Fifty-one hips were enrolled. Each patient received a VEPE liner, a porous titanium shell, and an un...
