The meniscus arrow is a T-shaped fastener that provides an "all inside" technique for repair of longitudinal meniscal tears in the vascular zone through arthroscopic portals. No posterior incisions are needed and there are no sutures to tie. The arrow is made of proprietary self-reinforced polylactic acid and is rigid enough to allow impaction across a torn meniscus. The design allows the "T" of the head to be driven into and hold onto the surface of the meniscus, while the shaft, with its "fish hook" barbs, crosses the tear to fix to the periphery. The arrows begin to degrade in 4 to 6 months and are absorbed in 18 to 24 months.
