Several controversies exist regarding the surgical difficulties and the results of total knee arthroplasty performed after failed valgus high tibial osteotomy (HTO), and the main subject is the change in patellar height that results as patella baja or infera. The purpose of this retrospective study was to evaluate patellar height after valgus HTO and the(More)
PURPOSE This study presents the short-term follow-up results from our case series of patients with posteriorly localized intraosseous talar cysts. Patients were treated via hindfoot endoscopy in the prone position. METHODS We evaluated six ankles of five patients treated with hindfoot endoscopy for intraosseous cysts localized to the posterior portion of(More)
In Sanders' classification of calcaneus fractures, the medial fracture line (subtype C) is close to the tarsal canal, which contains an artery for the talus and calcaneus. We hypothesized that because of this brittle vascular localization, patients with C line fracture patterns might describe radiologic subtalar arthritis more often and have more(More)
We dissected 80 shoulders from 44 fresh cadavers to define variants of the coracoacromial ligament and their relationship to rotator cuff degeneration. The shapes and the geometric data of the ligaments were investigated, and the rotator cuffs of the cadavers were evaluated macroscopically. Five main types of coracoacromial ligaments were found: Y-shaped,(More)
PURPOSE The aim of this study is to describe the indications for two-portal hindfoot endoscopy in the treatment of posterior ankle compartment pathologies and to express the effectiveness of this technique by short- to mid-term outcomes on 59 consecutive patients. METHODS In our institute, between 2003 and 2009, patients operated by single surgeon with(More)
BACKGROUND Cell-based strategies that combine in vitro- expanded autologous chondrocytes with matrix scaffolds are currently preferred for full-thickness cartilage lesions of the knee ≥2 cm(2). Although this approach is reasonable, continuing advances in the field of cartilage repair will further expand the options available to improve outcomes. (More)
Twenty fresh cadaveric elbows were used to evaluate the proximity of neurovascular structures to the six arthroscopic portals of the elbow at different positions. After distention of the joint, 4-mm Steinmann pins were introduced into the elbow from the portal's entry points. After surgical dissection, the proximity of the neurovascular structures to the(More)
We present a case report involving the flexor digitorum accessorius longus (FDAL) tendon which travels through a fibro-osseous tunnel together with the flexor hallucis longus (FHL) tendon, causing a stenosing tenosynovitis. The patient was admitted with posteromedial ankle pain and diagnosed clinically as FHL tenosynovitis. We found two tendons in the(More)
BACKGROUND The use of external ring fixation for ankle arthrodesis offers an alternative to internal screw fixation when bone quality is suboptimal, when complex ankle pathology is present, and as a salvage procedure for complicated cases. Additionally, it permits earlier weightbearing and postoperative adjustment of bone alignment and joint compression.(More)
PURPOSE This study evaluated the results of arthroscopic subchondral microfracture performed on patients with spontaneous osteonecrosis (ON) (group 1) or secondary ON (group 2) of the knee joint. TYPE OF STUDY Retrospective clinical study. METHODS Group 1 included 26 patients (mean age, 48 years) who had spontaneous ON. Group 2 included 15 patients(More)
