Ankle arthrodesis in patients with haemophilia-associated ankle arthropathy - does the technique influence the outcome?

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.

Characteristics and management of the haemophilia-associated pseudotumours.

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.

Three Cases of Femoral Stem Failure in Rotating Hinge Revision Total Knee Arthroplasty: Causes and Surgical Considerations.

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.

Biomechanical properties of bovine tendon xenografts treated with a modern processing method.

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.

Red cell distribution width is an independent predictor of mortality in hip fracture.

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.

Supracondylar femoral fracture after anterior cruciate ligament reconstruction with transfemoral fixation.

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.

Incidence of heterotopic ossification after hip resurfacing.

Background: Heterotopic ossification has been noted around total hip arthoplasty in numerous studies. With hip resurfacing growing in popularity, we have prospectively evaluated the incidence in a cohort undergoing hip resurfacing.

Methods: Two hundred and twenty consecutive hip-resurfacing procedures were prospectively reviewed at a minimum of 2 years follow up to assess the incidence of heterotopic ossification and its effect on function and clinical outcome.

How do serum cobalt and chromium levels change after metal-on-metal hip resurfacing?

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.

The nonoperative management of periprosthetic fractures associated with the Birmingham hip resurfacing procedure.

We reviewed the outcome of 7 patients sustaining undisplaced femoral neck periprosthetic fractures associated with the Birmingham hip resurfacing procedure. All fractures presented within 4 months of initial surgery. All fractures were treated conservatively with a period of nonweight bearing.

The octogenarian total knee arthroplasty.

Sixty-five patients aged > 80 years were compared to 65 patients aged between 60 and 70 years to assess total knee arthroplasty (TKA) outcome using the octogenarian postoperative Knee Society knee and function scores. Knee Society knee scores showed excellent outcomes with no statistically significant difference in the younger cohort (preoperative score, P = .7156; 5-year score, P = -.
