Existing techniques to address radial meniscus tears include all-inside horizontal mattress repair, transtibial pullout repair, and inside-out repair with either single, double, or crossed horizontal mattress sutures. Repair strength is an important factor because of the effects on healing potential and postoperative rehabilitation protocols. A recent biomechanical study compared a 2-tunnel transtibial pullout repair technique to a standard horizontal repair technique and reported improved performance with cyclic loading with the former. In this regard, this technique has been reported to produce durable results in a case report at early follow-up.
While there is debate over whether the repair of complete radial tears will result in adequate biomechanical performance and healing, few debate the benefits of repair- ing vertical meniscus tears because of the reported excellent outcomes for this tear pattern. Patients undergoing vertical tear repair therefore represent a relevant comparison group for those undergoing radial tear repair. Given the paucity of reported outcomes of radial meniscus tear repair techniques, the purpose of this study was to com- pare the outcomes for patients who underwent 2-tunnel transtibial pullout repair of a radial meniscus tear versus patients who underwent inside-out repair of a vertical meniscus tear at a minimum 2 years of follow-up. The hypothesis was that outcomes for radial tear repair were comparable with those for vertical tear repair.
