To critically evaluate exciting new technology to reconstruct menisci for the treatment of post menisectomy pain and relate results to indication and surgical technique in a non-inventor's general knee practice. We present our early experience of two non-comparative series with different meniscal implants. Series 1: Thirteen patients received a Menaflex implant (Regen Bio, USA). Mean age 30, male/female 11/2, mean length of implant 44mm, mean chondral grade 1.9 (Outerbridge). At 24 months clinical scores showed improvement in 12. Second look arthroscopy in 5 however showed disappointing amounts of regenerative tissue. One patient has been revised. Series 2: Twelve patients received an Actifit implant (Orteq, UK). Mean age 38, male/female 8/4, mean length implant 43 mm, mean chondral grade 1.3. At 12 months all have improved clinical scores. We have performed two second looks, one of these showed excellent integration. However one showed only 50% regeneration. Critical review of the initial implantation shows that there may not have been adequate preparation of the host meniscus tissue.Purpose
