BACKGROUND Some aspects of validity are missing for the Harris Hip Score (HHS). Our objective was to examine the clinically meaningful change thresholds, responsiveness and the predictive ability of the HHS questionnaire. METHODS We included a cohort of patients who underwent primary total hip arthroplasty (THA) and responded to the HHS preoperatively and at 2- or 5-year post-THA (change scor...

Forty years have elapsed since the first total hip arthroplasty in Croatia, a procedure that has revolutionized treatment of a whole range of states resulting in hip dysfunction and has brought about significant improvements in restoring functional ability and quality of life of the affected patients. Modern progress in the development of the hip joint endoprosthetics is closely connected to a ...

The benefits of converting an ankylosed or arthrodesed hip to total hip arthroplasty have been reported in the literature as have the technical difficulties associated with this procedure. This review, however, outlines the experience of a single surgeon (WJMB) at a single institution using uncemented prostheses. Between November 1991 and June 1996, 5 arthrodesed hips underwent uncemented total...

The direct anterior approach to hip arthroplasty has become a popular technique. This technique, which was described almost 70 years ago, allows the surgeon to approach the hip through an internervous and intermuscular plane. Preliminary studies show that direct anterior hip arthroplasty may allow patients to recover faster with a lower dislocation rate. It is helpful to understand the history,...

Despite increasing advantages in biomaterials, prosthetic designs, and implant fixation, clinical outcome of total hip arthroplasty (THA) has 10% failure rate after 10 years. Component malposition is well known to be responsible for instability, impingement, excessive wear and early loosening. Computer-assisted procedures are expected to improve the accuracy of the components positioning and al...

PURPOSE The purpose of this study was to assess the squeaking incidence and risk factors after primary ceramic-on-ceramic total hip arthroplasty (THA) in Asian patients using meta-analysis. MATERIALS AND METHODS We performed a meta-analysis of published data on the squeaking incidence and risk factors from 2000 to 2013. Eight studies in Asians were analyzed for both squeaking incidence and ri...

Correspondence We welcome letters to the Editor concerning articles which have recently been published. Such letters will be subject to the usual stages of selection and editing; where appropriate the authors of the original article will be offered the opportunity to reply. Letters should normally be under 300 words in length, double-spaced throughout, signed by all authors and fully referenced...

BACKGROUND Wear cannot be completely prevented after total hip arthroplasty. If severe polyethylene (PE) liner wear develops, the so-called catastrophic failure occurs and metallosis develops. We postulated that longevity of the new implant may be affected after revision surgery for metallosis following a catastrophic failure of a PE liner due to the substantial amount of PE wear particles and ...

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...

To avoid inadvertent vertical positioning of the acetabular component during total hip arthroplasty (THA), the authors routinely "cheat" component abduction an additional 10° horizontal (goal=30°). This likely increases the incidence of components placed into abduction of less than 30°, the clinical consequences of which are not well studied. The purpose of this study was to determine the clini...
