Abstract
Graft extrusion after meniscal allograft transplantation (MAT) has been reported to be a distinct feature of transplanted meniscus and has not been resolved. Biomechanically, insufficient articular cartilage coverage generated by graft extrusion leads to failure in normal biomechanics of knee joint. Causes of the graft extrusion are uncertain, but there are possible explanations such as preoperative size measurement error, geometrically unmatched graft, mal-positioned graft, overtensioning of the graft suture, or soft tissue contracture at the meniscocapsular junction. However, literature on the rehabilitation strategy to reduce meniscal graft extrusion is lacking. Our delayed rehabilitation program aims to restrict the initial range of motion and minimize the load on the graft up to three months after MAT. We suggest that this delayed rehabilitation can provide a positive effect on mechanical stabilization and biological healing of the graft protecting the healing process at the relatively weak meniscocapsular attachment.
