Chondral injury and synovitis after arthroscopic meniscal repair using an outside-in mulberry knot suture technique

Arthroscopic meniscal repair has a relatively low incidence of complications. We describe a novel complication of outside-in Mulberry knot repair of the medial meniscus, namely, aseptic synovitis and chondral injury. The presence of synovitis was diagnosed clinically and by multiple arthrocenteses and confirmed, along with a chondral lesion, by repeat arthroscopy. After subtotal meniscectomy, the synovitis subsided clinically.
