Abstract
Background: Symptomatic osteochondral lesions of the talus (OLTs) often require surgical intervention. There are various surgical methods. A generally valid, stage-dependent therapeutic algorithm does not exist. The aim of our study is to show long- term results of an alternative technique that combines retrograde drilling, debridement performed under arthroscopic visualization, and autologous bone grafting.
Methods: The surgical technique was performed in 24 patients with medial or lateral OLTs, and the data were analyzed retrospectively. In our technique, the affected subchondral bone was overdrilled retrogradely and resected under arthroscopic visualization (ossoscopy) without violating the cartilage. The resulting defect was filled with autologous bone from the medial tibia metaphysis. Outcome parameters were the numeric rating scale (NRS), the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, and range of motion (ROM). The Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was assessed and a possible correlation with the clinical outcome scores was calculated. Data concerning complication rates were also collected.
Results: The mean surface size of the OLTs was 0.9 ± 0.3 cm2. The mean follow-up was 89 months. The AOFAS score improved significantly from 57.7 points preoperatively to 88.8 points at the final follow-up (P < .0001). The pain value measured by the NRS decreased significantly from 8 to a pain level of 2. ROM improved in 37.5% of the patients for dorsiflexion and 29.2% for plantarflexion. There were no significant correlations between the MOCART score and the AOFAS score or the pain value on NRS.
Conclusion: Retrograde drilling, ossoscopy, and autologous bone grafting for OLTs is a promising technique with good long-term results. The patients' satisfaction rate, especially in OLT stages 2 and 3, was excellent.
期刊介绍：
Foot & Ankle International (FAI), in publication since 1980, is the official journal of the American Orthopaedic Foot & Ankle Society (AOFAS). This monthly medical journal emphasizes surgical and medical management as it relates to the foot and ankle with a specific focus on reconstructive, trauma, and sports-related conditions utilizing the latest technological advances. FAI offers original, clinically oriented, peer-reviewed research articles presenting new approaches to foot and ankle pathology and treatment, current case reviews, and technique tips addressing the management of complex problems. This journal is an ideal resource for highly-trained orthopaedic foot and ankle specialists and allied health care providers.
The journal’s Founding Editor, Melvin H. Jahss, MD (deceased), served from 1980-1988. He was followed by Kenneth A. Johnson, MD (deceased) from 1988-1993; Lowell D. Lutter, MD (deceased) from 1993-2004; and E. Greer Richardson, MD from 2005-2007. David B. Thordarson, MD, assumed the role of Editor-in-Chief in 2008.
The journal focuses on the following areas of interest:
• Surgery
• Wound care
• Bone healing
• Pain management
• In-office orthotic systems
• Diabetes
• Sports medicine
