Arthroscopic microfracture alone or combined application of acellular scaffold: Which one is more effective in the treatment of osteochondral lesions of the talus?

Background/Aim: The optimal treatment method of the talar osteochondral lesions (TOLs) is still controversial. Although success arthroscopic microfracture (AMFx) in smaller known, different methods are tried larger-sized TOLs. This study aimed to compare clinical and radiological outcomes single-step AMFx repair procedure combined application cell-free scaffold (CFS) Methods: retrospective cohort included patients presenting with a TOL larger than 1.5 cm2 3 between March 2015 June 2018 who received attended follow-up for at least 24 months. Eighteen (group 1) were treated method, 16 2) + CFS. American Orthopedic Foot Ankle Society (AOFAS), Visual Analog Scale (VAS), Tegner Activity Scores used evaluation, MOCART (magnetic resonance observation cartilage tissue) score was assess tissue. Results: mean patient age 33.47 (8.67) years time 32.24 (9.33) There no significant difference two groups terms (P=0.984), body mass index (P=0.450), defect size (P=0.081) (P=0.484). median AOFAS increased from preoperative assessment until 12 months 1 (P<0.001) group 2 (P<0.001). scores, or components score. Conclusion: Comparisons revealed that end 24-month similar groups. Therefore, TOLs appear benefit similarly CFS techniques.
