Objective: To introduce the surgical technique and the clinical results of harvesting the gracilis and semitendinosus tendons from the posteromedial corner for anterior cruciate ligament reconstruction. Methods: From 2014.8 to 2017.1,the technique was used in 23 patients with anterior cruciate ligaments ruptures.A horizontal incision of about 2- 3 cm was made on the posteromedial corner just above the flexor crease and the saphenous nerve was protected. The hamstring tendons were indentified and the lower limb of semitendinosus tendon was cut off. Free the tibial end of the tendons beneath the periosteum and cut it off. Then the tendons were harvested and prepared in routine method. Results: All patients had their tendons harvested completely and were followed up in an average of 24.5 months.No sartorius was falsely harvested and no hamstring tendons were harvested prematurely. 2 patient complaint of skin numbness in the saphenous nerve dominating area, but the symptoms were alleviated during follow-up period.. Conclusion: The study revealed harvesting the gracilis and semitendinosus tendons from the posteromedial corner could avoid injures to the saphenous nerve. The manipulation was easy with less complications and satisfactory results.
