Arthroscopic Management of Isolated Tibial Plateau Defect With Microfracture and Micronized Allogeneic Cartilage-Platelet-Rich Plasma Adjunct.

ABSTRACT: Articular cartilage lesions of the tibial plateau are an uncommonly encountered clinical entity, and they have been comparatively less well studied than femoral condyle or patellofemoral defects. The management of these lesions is complicated by the challenging geometry, difficult surgical approach, and proximity to important anatomic structures, and thus, treating these lesions by previously established methods, such as osteochondral allograft transplantation or osteochondral autograft transfer, can be a technically challenging endeavor. These lesions remain readily available to undergo microfracture, and this is the preferred method of management in the senior author's practice. Although less technically difficult and less invasive than other techniques, microfracture is currently limited by concerns over the long-term durability of the method. Current research seeks to improve the quality of cartilage fill stimulated by microfracture, and adjunct techniques have become increasingly popular. In this technical report, we present a technique for arthroscopic treatment of an isolated tibial plateau defect with microfracture using a micronized allogeneic cartilage (BioCartilage; Arthrex, Naples, FL) and platelet-rich plasma adjunct.

Project description:BackgroundDespite increased recognition of coexisting tibial and talar osteochondral lesions (OCLs), the risk factors influencing clinical outcomes remain unclear.PurposeTo report clinical follow-up results after arthroscopic microfracture surgery in patients with OCLs of the distal tibial plafond and talus and assess possible factors affecting these clinical outcomes.Study designCase series; Level of evidence, 4.MethodsA total of 40 patients with coexisting talar and tibial OCLs who underwent arthroscopic microfracture surgery were included. For analysis, the study used the American Orthopaedic Foot & Ankle Society (AOFAS) scale, Karlsson-Peterson scale, and visual analog scale (VAS) for pain for clinical evaluations on the day before surgery, 12 months after surgery, and at the last follow-up. A stepwise regression model and Spearman rank correlation were used to assess possible factors affecting these clinical outcomes.ResultsThe median follow-up time was 34.5 months (interquartile range [IQR], 26.5-54 months). At the final follow-up, the cohort included 40 patients (26 men and 14 women) with a mean age of 38.8 years (range, 19-60 years). The median AOFAS score increased from 57.5 (IQR, 47-65) before surgery to 88 (IQR, 83-92.5) at the final follow-up, the median Karlsson-Peterson score increased from 48 (IQR, 38.5-67) to 82 (IQR, 76-92), and the median VAS score improved from 5 (IQR, 4-6) to 1 (IQR, 0-2). All scale scores showed significant differences between the preoperative and final follow-up evaluations (P < .001). In the stepwise regression model and Spearman rank correlation analysis, the grade of tibial OCL had a significant independent effect on the final postoperative AOFAS scores of the patients (β = -0.502, P = .001; r = -0.456, P = .003). The size of the tibial lesion also had a significant independent effect on the final postoperative Karlsson-Peterson scores of the patients (β = -0.444, P = .004; r = -0.357, P = .024).ConclusionArthroscopic microfracture treatment for coexisting talar and tibial OCLs can achieve good short- to midterm clinical outcomes. The grade and size of tibial OCLs are the main risk factors affecting the prognostic functional scores of such patients.
