PURPOSE: To perform a systematic review comparing the clinical scores, union rate, complications, reoperations, hospital stay, and operation time between open ankle arthrodesis (OAA) and arthroscopic ankle arthrodesis (AAA). METHODS: We conducted a comprehensive search in the MEDLINE, Embase, and Cochrane Library databases. Only comparative studies were included in this meta-analysis. The literature search, data extraction, and quality assessment were conducted by 2 independent reviewers. The ou

PURPOSE: The purpose of this study was to investigate changes in coronal alignment of the ankle joint after HTO. Our hypothesis was that ankle joint orientation may become more parallel or less parallel to the ground after HTO, and this change may affect ankle symptoms. METHODS: Eighty-six knees were retrospectively analysed after HTO for varus osteoarthritis. Preoperative and follow-up whole-leg radiographs were taken. The hip-knee-ankle (HKA) angle and medial proximal tibial angle (MPTA) were

BACKGROUND: Among the types of osteochondral lesions of the talus (OLTs), the osteochondral and chondral types make up the majority of OLTs. There is a possibility that between these two types of lesions, the clinical outcomes and characteristics may differ. PURPOSE: This study was designed to compare the clinical outcomes, demographics, and characteristics of osteochondral- and chondral-type lesions of OLTs. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The authors retrospectively

In a retrospective study we compared 32 HINTEGRA total ankle replacements (TARs) and 35 Mobility TARs performed between July 2005 and May 2010, with a minimum follow-up of two years. The mean follow-up for the HINTEGRA group was 53 months (24 to 76) and for the Mobility group was 34 months (24 to 45). All procedures were performed by a single surgeon. There was no significant difference between the two groups with regard to the mean AOFAS score, visual analogue score for pain or range of movemen

There were no significant differences between the sexes regarding clinical outcomes after distal and proximal chevron osteotomy. However, male patients achieved greater correction of HVA than female patients. There is a possibility that sexual dimorphism of the foot may affect postoperative HVA.

Abstract We conducted a nationwide population-based cohort study to identify the risk factors associated with failure of total ankle arthroplasty (TAA). We included 2,914 subjects who underwent primary TAA between January 1, 2010, and December 31, 2016, utilizing the database of the Korean National Health Insurance Service. Failure of TAA was defined as revision TAA or arthrodesis procedures. An increased risk of TAA failure was observed in the < 65 age group versus the ≥ 75 age group [adjust

We reviewed 91 patients (103 feet) who underwent a Ludloff osteotomy combined with additional procedures. According to the combined procedures performed, patients were divided into Group I (31 feet; first web space release), Group II (35 feet; Akin osteotomy and trans-articular release), or Group III (37 feet; Akin osteotomy, supplementary axial Kirschner (K-) wire fixation, and trans-articular release). Each group was then further subdivided into severe and moderate deformities. The mean hallux
