Oxygen tensiometry as a predictor of wound healing in total ankle arthroplasty.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSION: Oxygen tensiometry is not thought to be useful for predicting patients at risk for postoperative wound healing complications after TAA, suggesting that, if adequate pulses are present before surgery, the trauma of using excessive superficial traction on the skin during surgery is more responsible for wound healing problems than the underlying blood supply.

Opening wedge tibial osteotomy for large varus deformity with CeraverTM resorbable beta tricalcium phosphate wedgesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The results in 53 knees that had been treated by proximal tibial opening-wedge osteotomy for large varus deformity and osteoarthritis of the medial compartment were evaluated after a mean length of follow-up of ten years (range, 8–12 years). We used a porous beta-tricalcium phosphate (β-TCP) wedge because it is resorbable and osteoinductive. All osteotomies were completely consolidated and complete osseointegration of the remnant of the β-TCP wedge took place. However, after a mean maximum follow-up of ten years none of the cases showed complete resorption. After ten years, 40 (81%) of...

Bone Graft Substitutes and Allografts for Reconstruction of the Foot and AnkleEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In reconstructive foot and ankle surgery, the use of bone graft is common. Whether for trauma, acquired or congenital deformities, arthrodeses, joint replacement, bone loss from infection, or bone tumor resection, the foot and ankle surgeon must be knowledgeable about current bone grafting options to make informed decisions. Innovation and technologic advances have produced an impressive and exciting array of options, advancing us closer to mimicking the gold standard: autograft. However, the sheer volume of available products makes it challenging for the foot and ankle surgeon to stay abreast of current bone graft technol...

Biologic Resurfacing of the Ankle and First Metatarsophalangeal Joint: Case Studies with a 2-Year Follow-UpEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The goal of biologic resurfacing is to provide a smooth joint surface with a low coefficient of friction, which allows the joint to function with near normal biomechanics, as well as provide intermittent pressure, to the subchondral and cancellous bone. This unique combination often results in the formation of a “neocartilage-like” structure that can reduce pain and restore biomechanics. As well as giving a brief history of cutis arthroplasty, this article describes cases in which the ankle and first metatarsophalangeal joint underwent biologic resurfacing, with a 2-year postoperative follow up.

Wear behaviour in total ankle replacement: A comparison between an in vitro simulation and retrieved prosthesesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Background: To minimise wear of the meniscal component in total ankle replacement, a three-component artificial joint has recently been developed. This new prosthesis has convex spherical tibial and anticlastic talar metal components with non-anatomic but ligament-compatible shapes in the sagittal plane, and a fully conforming ultra-high-molecular-weight-polyethylene meniscal component inserted in between. The in vitro wear of meniscal components can be assessed using a four-station joint simulator. The study was aimed at comparing wear patterns obtained in vitro with those observed in implant retrievals with the...

Complication Rates Following Open Reduction and Internal Fixation of Ankle FracturesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: By analyzing a large, diverse patient population, the present study clarifies the risks associated with open reduction and internal fixation of ankle fractures. Open injury, diabetes, and peripheral vascular disease were strong risk factors predicting a complicated short-term postoperative course. Fracture type was a strong predictor of reoperation for ankle fusion or replacement. Hospital volume did not play a significant role in the rates of short-term or intermediate-term complications. Level of Evidence: Prognostic Level II. See Instructions to Authors for a complete description of levels of evidence. (Source: JBJS [Am])

Utilizing a multicenter approach in observational clinical research allows for improved generalizability of the results, a larger sample size, and, consequently, improved efficiency. This paper highlights important issues with regard to the organization of multicenter observational studies in orthopaedic research. Specifically, we emphasize the development of trial committees, stress the importance of having a methods center for the purpose of coordinating day-to-day study activities, and describe the roles of the participating clinical sites. The successful conduct of multicenter studies requires careful study organizatio...

Qualitative Research: A Review of Methods with Use of Examples from the Total Knee Replacement LiteratureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Qualitative research is a useful approach to explore perplexing or complicated clinical situations. Since 1996, at least fifteen qualitative studies in the area of total knee replacement alone were found. Qualitative studies overcome the limits of quantitative work because they can explicate deeper meaning and complexity associated with questions such as why patients decline joint replacement surgery, why they do not adhere to pain medication and exercise regimens, how they manage in the postoperative period, and why providers do not always provide evidence-based care. In this paper, we review the role of qualitative metho...

Complication rates following open reduction and internal fixation of ankle fractures.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: By analyzing a large, diverse patient population, the present study clarifies the risks associated with open reduction and internal fixation of ankle fractures. Open injury, diabetes, and peripheral vascular disease were strong risk factors predicting a complicated short-term postoperative course. Fracture type was a strong predictor of reoperation for ankle fusion or replacement. Hospital volume did not play a significant role in the rates of short-term or intermediate-term complications.

Total ankle replacement in patients with significant pre-operative deformity of the hindfoot.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We carried out 123 consecutive total ankle replacements in 111 patients with a mean follow-up of four years (2 to 8). Patients with a hindfoot deformity of up to 10 degrees (group A, 91 ankles) were compared with those with a deformity of 11 degrees to 30 degrees (group B, 32 ankles). There were 18 failures (14.6%), with no significant difference in survival between groups A and B. The clinical outcome as measured by the post-operative American Orthopaedic Foot and Ankle Surgeons score was significantly better in group B (p = 0.036). There was no difference between the groups regarding the post-operative range of movem...

Conversion of painful ankle arthrodesis to total ankle arthroplasty.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: For patients with pain at the site of a failed ankle arthrodesis, conversion to total ankle arthroplasty with the use of a three-component ankle implant is a viable treatment option that provides reliable intermediate-term results. Key factors for the success of this procedure may be the intrinsic coronal plane stability provided by the ankle implants and the use of wider talar implants.
