We determined whether total hip arthroplasty (THA) patients could test their own prothrombin time reliably over 6 weeks of anticoagulation prophylaxis with a portable device that measures prothrombin time and whether self-testing would improve or maintain the quality of care at a lower cost than our standard procedure. Forty-six THA patients participated in the study and were compared with a ma...

Avascular necrosis (AVN) of the femoral head is a disease that affects younger patients (age range usually from 15 to 50 years), and which leads to debilitating arthritis often requiring total hip arthroplasty (THA) for disabling pain. However, neuromuscular diseases, such as, cerebral palsy and poliomyelitis, are a concern in patients with THA, because dislocation frequently occurs after surge...

Avascular necrosis of the femoral head (AVNFH) is a known complication after heart transplantation. In order to assess the efficacy and complications of cementless total hip arthroplasty (THA) in this population, the authors analysed 24 cementless THAs in 18 patients with advanced AVNFH (stage II affecting more than 15% of the articular surface, stage III and IV according to the Ficat-Arlet cla...

BACKGROUND AND PURPOSE The reported outcomes of hip resurfacing arthroplasty (HRA) vary. The frequency of this procedure in Denmark, Norway, and Sweden is low. We therefore determined the outcome of HRA in the NARA database, which is common to all 3 countries, and compared it to the outcome of conventional total hip arthroplasty (THA). METHODS The risk of non-septic revision within 2 years wa...

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...

PURPOSE To investigate the incidence of deep vein thrombosis (DVT) following total hip arthroplasty (THA) in Singaporean patients. METHODS 197 patients (mean age, 60 years) underwent primary THA (n=155) or revision procedure (n=42) without receiving routine chemoprophylaxis. There were 149 Chinese, 25 Malays, 19 Indians, and 4 Eurasians. Duplex ultrasonography to detect DVT was performed on b...

Total hip arthroplasty (THA) is a common procedure for primary osteoarthritis, but increasing numbers are also being performed for other pathologies such as secondary arthritis, inflammatory arthropathies and trauma. Estimates suggest that around 8.5 million people in the UK are affected by joint pain secondary to arthritis and a rising ageing population has resulted in an increase in THA opera...

While revision of total hip arthroplasty (THA) is being performed with increasing frequency, outcomes of repeated revisions have been rarely reported in the literature. The purpose of this study was to report mid-term outcomes of re-revision of failed revision THA acetabular components. We performed at least two revisions of the failed acetabular component in 57 patients (57 hips) between Augus...
