TY - JOUR T1 - Lateral Transfer of the Medial Hamstring Tendons to the Fibula to Treat Anterolateral Rotatory Instability of the KneeA Case Report AU - Bell, Douglas AU - Pedersen, Elizabeth Y1 - 2009/05/01 N1 - 10.2106/JBJS.H.00420 JO - The Journal of Bone & Joint Surgery SP - 1214 EP - 1218 VL - 91 IS - 5 N2 - Anterolateral rotatory instability, or anterior-internal rotation instability, is typically associated with deficiency of the anterior cruciate ligament1-3. In fact, anterior cruciate ligament insufficiency has been called the sine qua non of anterolateral rotatory instability. Many techniques were described to reduce this anterolateral laxity with use of extra-articular tenodesis or tendon transfers1,2,4,5 before intra-articular techniques were developed6,7. We present the case of a patient who, as a result of traumatic loss of the lateral thigh muscles, had anterolateral rotatory instability of the knee without anterior cruciate ligament deficiency; this condition was treated with a lateral transfer of the gracilis and semitendinosus tendons to the fibula. To our knowledge, this technique has not been described previously in the English-language literature. Our patient was informed that data concerning the case would be submitted for publication, and he consented.
