INFLAMMATORY JOINT DISEASE
Between January 2021 and April 2022, 211 patients underwent intra-articular injection of ADSCs and BMAC in our department. Of those, 37 patients were excluded because they received both knee arthroscopy and BMAC or ADSCs, and 23 patients were excluded because they were classified as Kellgren-Lawrence grade 1. Eight patients were excluded because older than 75 years, and 14 patients because they had body mass index < 18 or ≥ 35. Nine patients presented concomitant involvement of ligaments and/or menisci, and infectious or inflammatory joint disease. Three patients with a severe (> 10°) varus or valgus deformity were excluded. Ten patients did not consent to the post-operative interviews, and five patients underwent arthroscopic surgery for meniscal injury after intra-articular injection. The remaining 102 patients were included in this study (Fig. STROBE flow chart
