BACKGROUND Preserving the hip joint to delay arthroplasty for patients with acetabular dysplasia-associated early-stage osteoarthritis has become more common, and several surgical procedures have demonstrated pain relief and improved hip joint function. Periacetabular osteotomy, one of the joint-preserving surgical procedures of the hip, provides favorable outcomes, although there are no report...

Total hip arthroplasty (THA) is one of the most reliable procedures that can provide shortterm high clinical success rates and long-term durable outcome. The surgery has been developed for more than 40 years and most of the clinical practices are standardized for the patient care. In the past, THA had been done by making a wound about 25 cm in length. Many surgeons believed that big wounds shou...

One of the most common causes for revision surgery following total hip arthroplasty (THA) is dislocation.Dislocation is associated with a considerable amount of suffering and risks for the patient, and extra costs for the health care system.Compared with degenerative arthritis, the dislocation rate is doubled for avascular necrosis and multiplied by three times for congenital dislocation, four ...

My interest in cementless Total Hip Arthroplasty began in 1993 when I was introduced to the experimental PCA-Howmedica system while visiting Dave De Young at NCSU Veterinary College. After previous experience with cemented prostheses, I was looking for a commercially available cementless system to eliminate the complications I had encountered with cemented hips, mainly aseptic implant loosening...

Distal deep vein thrombosis (DVT) can range from being asymptomatic, to resulting in long term valvular damage resulting in chronic venous insufficiency. Proximal propagation can result in more serious pulmonary embolism. The overall incidence of DVT, including both radiologically diagnosed asymptomatic DVT and symptomatic DVT, post THA in early studies was reported to be as high as 70% without...

BACKGROUND AND PURPOSE An increasing number of patients have several joint replacement procedures during their lifetime. We investigated the use and suitability of multi-state model techniques in providing a more comprehensive analysis and description of complex arthroplasty histories held in arthroplasty registries than are allowed for with traditional survival methods. PATIENTS AND METHODS ...

We investigated the isokinetic performance of hip muscles and clinical outcomes after revision total hip arthroplasty (THA) via same anterolateral approach used in primary surgery. Thirty patients who had undergone previous THA via an anterolateral approach underwent both acetabular and femoral component revision after aseptic loosening. The Harris Hip Score (HHS) was evaluated during a minimum...

developmental dysplasia of the hip (ddh) or congenital hip dysplasia (cdh) is the most prevalent developmental childhood hip disorder. it includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. the natural history of neglected ddh in adults is highly variable. the mean age of onset of symptoms is 34.5 years for dysplastic dd...

OBJECTIVE Leg length discrepancy is common both in healthy subjects and after total hip arthroplasty (THA). Studies that evaluated leg length following THA have demonstrated a notable inconsistency in restoring leg length. The effects concerning joint load during gait is however not well known. The purpose of this study was to use three-dimensional (3D) gait analysis to evaluate joint load duri...
