Arthroscopic Meniscus Repair: Inside-Out Technique

Abstract

Henning¹ performed the first arthroscopic inside-out meniscus repair in February 1980 and later described the technique. He developed a single cannula with short, double-armed sutures, which passed through the torn portion of the meniscus and the capsule to stabilize and approximate the tear. Subsequently, double-lumen cannulas were introduced to prevent suture entrapment by the second needle. Rosenberg’s group² introduced a zone-specific system with long double needles and bent cannulas to accommodate the specific zone of meniscus to be repaired. Their single-lumen system is smaller, more maneuverable, and better able to fit into tight spaces than a double-lumen system. The long double needles are easier to retrieve from the posterior capsule than Henning’s shorter ones.
