Article Abstract
Background: Over the last twenty years, minimally invasive ankle arthrodesis has evolved into a well-tolerated and safe procedure. It has grown in favor to open ankle arthrodesis due to shorter length of stay and fewer complications recorded. This paper aims to compare the clinical outcomes of arthroscopic vs open ankle arthrodesis at 24-months followup.
Methods: From 2004 to 2015, we reviewed a prospectively collected database in a tertiary hospital foot and ankle registry. 28 feet that underwent arthroscopic ankle arthrodesis were matched to 56 feet that underwent open ankle arthrodesis for age, sex and body mass index (BMI). Visual analogue scale (VAS) scores, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-hindfoot Scores and Short Form Health Survey (SF-36) were obtained to assess clinical outcomes. These parameters were collected before surgery, at 6months and 24months after surgery.
Results: The arthroscopic group demonstrated significant less pain in the perioperative period (arthroscopic: 1.9±1.2, open: 3.8±1.1, p<0.001) and shorter length of hospitalization stay (arthroscopic: 2.1±0.7 open: 3.5±1.7, p<0.001). Patients who underwent arthroscopic ankle arthrodesis also reported a higher SF-36 score on physical functioning at 6months (arthroscopic: 58.4±27.1, open: 47.1±24.0, p<0.05) and higher AOFAS Ankle-hindfoot Scale score at 24-months (arthroscopic: 78.9±18.9, open: 68.9±24.7, p<0.05). There were no postoperative complications in the arthroscopic group but 11 in the open group, including 9 which required followup operations. There was no significant difference in length of operative procedure between both groups.
Conclusions: We conclude that the arthroscopic group displayed better clinical outcomes compared to the open group at the 24months followup. The advantages of arthroscopic ankle arthrodesis include significantly less perioperative pain, higher AOFAS Ankle-hindfoot scores at 24months, shorter length of stay, fewer postoperative complications and followup operations.
Level Of Evidence: Level III, retrospective comparative series.

Vascularized reconstruction of bone defects in the foot after osteomyelitis is a complex procedure that requires an orthoplastic collaboration. This case demonstrates the successful use of a free osteocutaneous fibula flap with a perforator-based skin island to reconstruct the medial midfoot following a late-onset infection after fusion for osteonecrosis. A 63-year-old woman presented after osteonecrosis and failed surgeries, including talonavicular and naviculocuneiform arthrodesis complicated by infection.

Background: Distraction arthroplasty aims to treat ankle osteoarthritis while preserving the native ankle joint, often to prevent or delay ankle arthrodesis or total ankle replacement (TAR). No study to date has explored TAR outcomes in patients who have had prior distraction arthroplasty. Thus, this study described the clinical, radiographic, and patient-reported outcomes for TAR at minimum 2-year follow-up in patients who had undergone prior ankle distraction arthroplasty.

Background: Subtalar joint (SJ) fusion may be required to treat subtalar osteoarthritis in progressive collapsing foot deformity (PCFD). Our goal was to understand how anterolateral arthroscopic subtalar arthrodesis (ALAPSTA) may alter joint congruency at the tibiotalar level.
Methods: We retrospectively assessed pre- and postoperative weightbearing computed tomography images of patients diagnosed with PCFD 2A (arthritic SJ) and/or 2D (peritalar subluxation) which underwent isolated ALAPSTA.
