Management of symptomatic osteoarthritis (OA) of the ankle in patients with haemophilia can be challenging. Arthroscopic ankle arthrodesis has been shown in non-haemophiliac patients to provide similar or superior rates of fusion to open ankle fusion. However, the literature regarding ankle arthrodesis in patients with haemophilia is limited.

Background: Restoration of neutral mechanical axis is thought to influence implant survival and function in Total Knee Arthroplasty (TKA). There is no consensus whether Intramedullary (IM) or Extramedullary (EM) tibial alignment technique is superior to achieve this outcome. Study aims to evaluate functional and radiological outcome of TKA using the EM and IM technique.

Introduction The consenting process has been surgeon-focussed traditionally, but there is a recent trend towards making the process more patient and procedure-focussed. The primary aims were to identify the risks considered most important and requiring further discussion by the patients undergoing primary total hip arthroplasty (THA) and primary total knee arthroplasty (TKA), as well as to identify the sporting and recreational activities these patients would like to pursue after surgery according to the age group, taking into consideration their values and expectations. The secondary aim is to assess the compliance of the current consenting process with guidelines set out by a governing body in a tertiary referral arthroplasty unit.

The management of haemophilia-associated pseudotumours presents an ongoing challenge to the haematologist, surgeon and interventional radiologist alike. There is a range of therapeutic approaches including factor replacement, embolization, radiotherapy and a variety of surgical interventions. However, there remains little evidence regarding the most appropriate treatment.

Catastrophic failure of stemmed components in arthroplasty is an uncommon but a serious complication. Stem fractures and techniques for addressing these have been described following hip arthroplasty but much less so following total knee arthroplasty (TKA). We review three cases of catastrophic failure of the stem in rotating hinge revision TKA prostheses.

Xenograft tendons have been used in few human studies, with variable results. With the advent of novel tissue processing techniques, which may mitigate against an immune-mediated rejection response without adversely affecting mechanical properties, there may now be a clinical role for xenograft tendons, particularly in knee ligament reconstruction. We hypothesize that 'BioCleanse®' processed bovine extensor digitorum medialis (EDM) tendons exhibit favorable time-zero pre-implantation biomechanical characteristics when compared to both unprocessed bovine EDM tendons and BioCleanse® processed human cadaveric allograft tibialis anterior tendons.

Unlabelled: Haemophilic arthropathy is a complex multifactorial disorder that poses significant challenges to both the treating haematologist and arthroplasty surgeon. Its pathogenesis is incompletely understood. Recent literature has concentrated on the toxic effects of iron and the characteristic inflammatory synovitis.

Objective: The objectives of our study were to assess the evidence for the diagnostic efficacy of 3-T MRI for meniscal and anterior cruciate ligament (ACL) injuries in the knee using arthroscopy as the reference standard and to compare these results with the results of a previous meta-analysis assessing 1.5-T MRI.

Materials And Methods: The online Cochrane Library, MEDLINE, and PubMed databases were searched using the following terms: MRI AND ((3 OR three) AND (Tesla OR T)) AND knee AND arthroscopy AND (menisc* OR ligament).

Background: Knee osteoarthritis after anterior cruciate ligament (ACL) injury has previously been reported. However, there has been no meta-analysis reporting the development and progression of osteoarthritis.

Purpose: We present the first meta-analysis reporting on the development and progression of osteoarthritis after ACL injury at a minimum mean follow-up of 10 years, using a single and widely accepted radiologic classification, the Kellgren & Lawrence classification.

The trends in the publication of articles regarding knee arthroplasty and soft tissue surgery were analysed with regard to geographical authorship, institutional funding and number of authors. Over 7500 articles from relevant journals with the highest impact factors according to the Thomson Reuters Journal Citation Report (2010) were evaluated from 1995 to 2010. The rate of publication increased by 16.

Background: the red cell distribution width (RDW), an automated measure of variability in the red blood cell size on full blood count (FBC) is an independent predictor of mortality in several disease states and in healthy older people.

Objective: we wanted to determine the prognostic value of RDW in patients following a hip fracture-a condition associated with high mortality.

Design: we examined the relationship between admission RDW and mortality in 698 consecutive patients admitted with hip fracture.

The authors report two cases of pyroglutamic acidosis as a result of paracetamol and flucloxacillin therapy in patients with prosthesis infection following hemiarthroplasty for neck of femur fractures. Pyroglutamic acidosis is an important and often unrecognised cause of refractory metabolic acidosis that disproportionately affects older women, and can be caused by drugs such as paracetamol and flucloxacillin in the setting of sepsis, renal failure and malnutrition. Although relatively rare, the widespread use of these drugs in orthopaedic patients confirms the importance of this disorder.

Femoral fractures following anterior cruciate ligament (ACL) reconstruction are rare. These injuries often are related to increased stresses at the femoral tunnel. Hamstring tendon autograft is often used for ACL reconstruction, and transfemoral fixation is one of many graft fixation techniques with few reported complications.

Hip resurfacing using metal-on-metal bearings has increased in popularity as a viable treatment option for young, active patients with osteoarthritis. Theoretic advantages of this procedure include preservation of bone stock, reduction in osteolysis, and a reduced risk of dislocation when compared with conventional hip arthroplasty with smaller diameter metal-on-polyethylene bearings. Concerns associated with the use of metal-on-metal bearings during hip resurfacing include the production of metal ions with unknown carcinogenic and immunologic effects.

We prospectively monitored changes in serum cobalt and chromium levels after a new generation metal-on-metal hip resurfacing and the affect on renal function. Levels were measured using inductively coupled plasma mass spectrometry and atomic absorption spectrometry, preoperatively then sequentially at 3, 6, 9, 12, and 24 months. For serum cobalt, there was an initial increase to a peak level at 6 months, followed by a gradual decline during the next 15 months.
