Résumé
Introduction: Osteochondritis dissecans of the talus is a rarecondition that can create challenges for both the patient andthe treating surgeon. Arthroscopic bone marrow stimulation(i.e. microfracture, drilling) is a well-accepted and proventechnique to allow fibrocartilage differentiation and therebyprovide infill at the site of a cartilage defect in several joints,including the ankle. The aim of our study was to examine therole of arthroscopic bone marrow stimulation techniques as ameans of treatment for osteochondral lesions of the talus.Material and methods: Thirty two ankles were identifiedbetween January 2012 and January 2020 with talus OCD thatunderwent arthroscopic bone marrow stimulation. Each lesionwas classified according to the Berndt and Harty classification.Study patients were evaluated at 6 weeks, 3 months, 6 months,12 months, and annually after surgery. Assessments via avisual analogue scale (VAS) for pain during daily activitiesand sport activity and the American Orthopaedic Foot & AnkleSociety (AOFAS) scoring system were obtained at each visit.Result: There were 25 men and 4 women of average age 35years (range 17–50) and mean body mass index (BMI) 22 kg/m2 (range 20–34) at the time of surgery. Quantitative MRImeasurements on 3D FSPGR Sequence showed that meanarea of the lesions were 0.801 ± 0.505 cm2. Mean AOFASscores improved from 66 points (range 53–77) preoperativelyto 90 points (range 83–100) at final follow-up (p<0.05) andmean Visual Analogue Scale (VAS) scores from 6 points(range 5–8) to 2 points (range 0–5) with p value <0.05 whichis statistically significant.Conclusion: Arthroscopic management of osteochondrallesions of the talus has the advantages of better cosmeticresults, less pain, and less surgical trauma. This techniqueis technically demanding and should be reserved for theexperienced foot and ankle arthroscopist.
