A reduced range of motion post total knee replacement (TKR) is a recognised problem. Manipulation under anaesthesia (MUA) is commonly performed in the stiff post-operative TKR. Long-term results are variable in the literature. We retrospectively reviewed, prospectively collected data on 48 patients followed up since 1996 from one centre, over an average of(More)
Osteoporosis is characterized by a decreased bone mass and an increased bone fragility and susceptibility to fracture. Patients with a fragility fracture at any site have an increased risk of sustaining future fractures. Orthopedic surgeons manage most of these fractures and are often the only physician seen by the patient. Mounting evidence that orthopedic(More)
We present the clinical and radiological results of a prospective study of a consecutive series of patients treated with the Birmingham Hip Resurfacing (BHR) prosthesis between 1999 and 2006 and followed for six to 12 years. Patients were reviewed preoperatively and six, 12, 26 and 52 weeks postoperatively and annually thereafter. They were assessed(More)
BACKGROUND Approximately 10% of patients with osteoarthritis (OA) of the knee have unicompartmental OA confined to the patellofemoral joint (PFJ). The main surgical options are total knee replacement (TKR) and PFJ replacement (PFJR). PFJR has a number of advantages over TKR, including being less invasive, preserving the unaffected parts of the knee,(More)
Animal experiments indicate that angiotensin II can, under some circumstances stimulate the sympathetic nervous system at a number of different sites. In order to determine whether such a relationship of the renin-angiotensin and sympathetic nervous system exists in man, we increased (by intravenous infusion), or decreased (by administering the oral(More)
The most common indication for knee arthrodesis is pain and instability in an unreconstructable knee following an infected knee arthroplasty. In this study, we compare the use of the Mayday arthrodesis nail (Orthodynamics, Christchurch, UK) versus external fixation, Orthofix (Berkshire UK) and Stryker Hoffman II (County Cork, Ireland). All patients in this(More)
The use of plasma renin assays in clinical practice is reviewed and experience with an assay for plasma renin activity (PRA) is reported. In normal subjects, 10am ambulant PRA was significantly related to plasma angiotensin II levels but not related to daily urine sodium exretion in these subjects consuming normal diets. PRA was suppressed in patients with(More)
We present the extended follow-up (≥ 20 years) of a series of fully hydroxyapatite-coated femoral components used in 72 primary total hip replacements (THRs). Earlier results of this cohort have been previously published. All procedures were performed between 1986 and 1991. The series involved 45 women and 15 men with 12 bilateral procedures. Their mean age(More)
Substantial evidence exists that during fetal ovarian development in mammals, retinoic acid (RA) induces germ cells to express the pre-meiotic marker Stra8 and enter meiosis, and that these effects are prevented in the fetal testis by the RA-degrading P450 enzyme CYP26B1. Nonetheless, the role of RA has been disputed principally because germ cells in(More)
BACKGROUND There have been several large originator studies reporting excellent results with this prosthesis but far fewer large independent studies. We present, to our knowledge, the largest independent series documenting excellent survivorship rates and good functional outcomes at a mean follow up of 5.5 years post implantation of the Oxford(More)
