Patellofemoral instability and articular cartilage reconstruction with MaioRegen chondroplus scaffold. A two-year follow-up

Abstract

Accordingly, to the literature around 41 % of patellar instability closely related to the articular cartilage damage and later osteoarthritis in the PF region. In my clinical practice, I see twice more articular cartilage damage along with patella dislocations.During the 2015 - 2020 year period I have personally performed – various patella stabilization procedures for the 81 patient after dislocation of the patella and found articular cartilage damage together with patello-femoral instability in 89 % of cases.Here we review cases of patellar instability and patellofemoral compartment articular cartilage reconstruction performed at the same procedure. In most of these surgery cases, a V shape MPFL reconstruction performed with gracillis tendon. In those cases, when grade IV articular cartilage defects was found in to patella or the patello-femoral trochlea – a simultaneous AMIC arthroscopic or mini open procedure with MaioRegen chondroplus scaffold and fibrin glue fixation was performed. Some of the patients (one patient had undergone bilateral TT transposition, MPFL reconstruction and articular cartilage restoration with MaioRegen chondroplus scaffold and fibrin glue in one stage) were treated with concomitant TT transposition, MPFL reconstruction and articular cartilage restoration with MaioRegen chondroplus scaffold and fibrin glue in one stage. All cases were scored with Kulaja scoring system pre and postoperatively, TT-TG ratio were calculated in all of cases, patella height, J sigh, Dejour dysplasia grading and MRI were evaluated in all of the cases. We present a two-year follow-up of all different cases.
