Short-term results of total ankle arthroplasty for end-stage ankle arthritis with severe varus deformity.

Background: Many authors have reported that an ankle varus deformity more than 10 to 15 degrees may be the cause of failures in total ankle arthroplasty. Our study aim was to analyze short-term outcomes of total ankle arthroplasty with additional procedures accompanied by more than 20 degrees of varus deformity.

Methods: Among the patients who received total ankle arthroplasty for end-stage osteoarthritis between June 2006 and May 2012, 103 cases that were followed for more than 6 months were reviewed.

The effect of ossicle resection in the lateral ligament repair for treatment of chronic lateral ankle instability.

Background: The management of an ossicle or avulsion fragment of the fibular tip in chronic lateral ankle instability is an open question. Some authors maintain the necessity of osteosynthesis for reconstruction of the lateral ligamentous structure if the fragment is large. We hypothesized that the modified Broström procedure with resection of the ossicle would result in good outcomes compared to that of the same procedure for chronic lateral instability patients without ossicle.

The difference of surgical site infection according to the methods of lumbar fusion surgery.

Study Design: Retrospective analysis.

Objective: To compare the rates and types of a surgical site infection according to the surgical options in spine surgeries.

Summary Of Background Data: Scant literatures exist on the difference of surgical site infection according to the surgical methods.

The analysis of risk factors in no thumb test in total knee arthroplasty.

Background: We would like to analyze the risk factors of no thumb test among knee alignment tests during total knee arthroplasty surgery.

Methods: The 156 cases of total knee arthroplasty by an operator from October 2009 to April 2010 were analyzed according to preoperative indicators including body weight, height, degree of varus deformity, and patella subluxation and surgical indicators such as pre-osteotomy patella thickness, degree of patella degeneration, no thumb test which was evaluated after medial prepatella incision and before bone resection (1st test), no thumb test which was evaluated with corrective valgus stress (2nd test, J test), and the kind of prosthesis. We comparatively analyzed indicators affecting no thumb test (3rd test).
