Comparative Study Clinical TrialTwo-year outcomes of MOBILITY Total Ankle Replacement.
There is little literature on patient-reported outcomes following total ankle replacement in patients with osteoarthritis, posttraumatic osteoarthritis, and rheumatoid arthritis. We compared the differences in demographic data and clinical and patient-reported outcomes among patients with those types of arthritis who underwent total ankle replacement performed with use of the MOBILITY Total Ankle System. ⋯ Our findings suggest that early outcomes after total ankle replacement for patients with posttraumatic osteoarthritis are comparable with those for patients with osteoarthritis and rheumatoid arthritis.

Younger age is associated with a higher risk of early periprosthetic joint infection and aseptic mechanical failure after total knee arthroplasty.
Although early aseptic mechanical failure after total knee arthroplasty has been reported in younger patients, it is unknown whether early revision due to periprosthetic joint infection is more or less frequent in this patient subgroup. The purpose of this study was to determine whether the incidence of early periprosthetic joint infection requiring revision knee surgery is significantly different in patients younger than fifty years of age compared with older patients following primary unilateral total knee arthroplasty. ⋯ Patients younger than fifty years of age had a significantly higher risk of undergoing revision due to periprosthetic joint infection or to aseptic mechanical failure at one year after primary total knee arthroplasty.

Declining rates of osteoporosis management following fragility fractures in the U.S., 2000 through 2009.
Clinical practice recommendations state that patients with fragility fractures should be evaluated for osteoporosis and treated for the disease if it is present. The purpose of this study was to assess osteoporosis evaluation and treatment patterns for patients with fragility fractures and assess whether anti-osteoporosis pharmacotherapy initiated immediately following a fragility fracture is associated with improved adherence to the treatment protocol. ⋯ Clinical guidelines for evaluation and treatment following fragility fracture were met for less than one-third of women and less than one-sixth of men. While primary fracture prevention remains the ideal, secondary prevention is critical and there is a need to reverse the downward trend in adherence to post-fracture guidelines.

Addressing hindfoot arthritis with concomitant tibial malunion or nonunion with retrograde tibiotalocalcaneal nailing: a novel treatment approach.
Tibial malunions and nonunions are associated with degenerative changes about the ankle. A comprehensive literature review revealed no articles discussing treatment options for patients with tibial shaft malunion and ipsilateral ankle arthritis. The aim of our study was to evaluate a series of patients in whom tibial osteotomy and retrograde tibiotalocalcaneal nailing were used to treat both tibial deformity and ankle osteoarthritis. ⋯ Tibial malunion or nonunion with concomitant hindfoot arthritis can be addressed with a single-stage procedure consisting of tibial osteotomy and retrograde intramedullary nailing for correction of the angular deformity and hindfoot fusion. This procedure provides a viable alternative to multiplanar external fixation or a staged procedure addressing the nonunion or angular deformity and the hindfoot arthritis separately.

Evaluation of skill level between trainees and community orthopaedic surgeons using a virtual reality arthroscopic knee simulator.
Several virtual reality simulators have been developed to assist orthopaedic surgeons in acquiring the skills necessary to perform arthroscopic surgery. The purpose of this study was to assess the construct validity of the ArthroSim virtual reality arthroscopy simulator by evaluating whether skills acquired through increased experience in the operating room lead to improved performance on the simulator. ⋯ Higher levels of surgeon experience resulted in improved efficiency when performing diagnostic knee arthroscopy on the simulator. Further validation studies utilizing the simulator are currently under way and the additional simulated tasks of arthroscopic meniscectomy, meniscal repair, microfracture, and loose body removal are being developed.
