Osteochondral lesions of the talus (OLT) are a common cause of disability and chronic ankle pain. Many operative treatment strategies have been introduced; however, they have their own disadvantages. Recently lesion repair using autologous cartilage chip has emerged therefore we investigated the efficacy of particulated autologous cartilage transplantation (PACT) in OLT. We retrospectively analyzed 32 consecutive symptomatic patients with OLT who underwent PACT with minimum one-year follow-up. Standard preoperative radiography and MRI were performed for all patients. Follow-up second-look arthroscopy or MRI was performed with patient consent approximately one-year postoperatively. Magnetic resonance Observation of Cartilage Repair Tissue (MOCART) score and International Cartilage Repair Society (ICRS) grades were used to evaluate the quality of the regenerated cartilage. Clinical outcomes were assessed using the pain visual analogue scale (VAS), Foot Function Index (FFI), and Foot Ankle Outcome Scale (FAOS).Aims
Methods
Treatment for delayed wound healing resulting from peripheral vascular diseases and diabetic foot ulcers remains a challenge. A novel surgical technique named ‘tibial cortex transverse transport’ (TTT) has been developed for treating peripheral ischaemia, with encouraging clinical effects. However, its underlying mechanisms remain unclear. In the present study, we explored the potential biological mechanisms of TTT surgery using various techniques in a rat TTT animal model. A novel rat model of TTT was established with a designed external fixator, and effects on wound healing were investigated. Laser speckle perfusion imaging, vessel perfusion, histology, and immunohistochemistry were used to evaluate the wound healing processes.Aims
Methods
The purpose of this study was to compare the clinical and radiographic
outcomes of total ankle arthroplasty (TAA) in patients with pre-operatively
moderate and severe arthritic varus ankles to those achieved for
patients with neutral ankles. A total of 105 patients (105 ankles), matched for age, gender,
body mass index, and follow-up duration, were divided into three
groups by pre-operative coronal plane tibiotalar angle; neutral
(<
5°), moderate (5° to 15°) and severe (>
15°) varus deformity.
American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot
score, a visual analogue scale (VAS), and Short Form (SF)-36 score
were used to compare the clinical outcomes after a mean follow-up period
of 51 months (24 to 147).Aims
