Meniscus injury is a very common injury in knee joint. Meniscus injury may result in knee joint pain, snapping, locking, and later even osteoarthritis. Due to poor healing capability of broken meniscus after injury, meniscus repair or meniscectomy was often used based on the location and type of torn muniscus. For the reason of prevention of later osteoarthritis, higher requirements for keeping meniscal integrity and functions at the meantime of eliminating symptoms and signs were strongly proposed, which requires the meniscal repair as much as possible. Comprehensive knee arthroscopy examination was performed before repairing injured meniscus so as to identify the position, type, and breach length of the torn cartilage and to determine if meniscal repair is available with autograft tendon fiber suture. Then autograft tendon material was harvested and prepared with suitable fibers length and diameter, with which the meniscus was sutured arthroscopically. Brace was used for 4 weeks postoperation, and functional rehabilitation exercise was performed by patients gradually. Thirty-five patients were treated and followed up for 11 months with this technique The results showed that symptoms disappeared and the normal knee function scoring was regained. Lysholm knee function score was 59 ± 9.8 before operation and 94 ± 5.4 3 months after operation (P < 0.01). Twenty-two (65.7%) of all cases returned to their previous activity level after 3 months postoperation.
