RESUMEN
Aim To investigate the clinical importance of a newly designed tenodesis with polymolecular polyethlene fastener. Methods Eighty-nine patients with knee ligaments injuries were reconstructed with the technique of newly designed tenodesis. Rehabilitation program started under the instruction of the therapist from the next day of the surgery.Results The tenodesis on all patients in our study were successful. The fasteners in two patients and the transplants in three patients were blocked in the bone tunnel during the operation. One fastener was taken out from the bone tunnel under arthroscopy. The patients were followed up for 19 months averagely (from 6 months to 49 months), most of them showed a stable knee without complain, except two patients feel uncomfortable after vigorous activities; seven patients show little laxity in anterior drawer test (ADT) or posterior drawer test (PDT) and three patients had 20-degree limitation of knee flexion. Lysholm scale score were 56?8 and 89?5 before and after operation, respectively ( P
