CPT® Code 27396

The CPT® Code 27396 refers to a surgical procedure involving the transplant or transfer of muscle within the thigh, specifically focusing on the redirection or rerouting of muscle action. This procedure is performed on a single tendon, which can be either an extensor or a flexor. The primary goal of this intervention is to address muscular imbalances in the thigh that can lead to knee dysfunction and difficulties in walking. By transferring or transplanting a tendon, the surgeon aims to minimize the dysfunction caused by these imbalances, thereby improving the patient's mobility and overall function. For instance, a common example of this procedure involves the rectus femoris muscle, one of the four quadriceps muscles that plays a crucial role in knee extension. In cases where knee function is compromised, the rectus femoris may be surgically repositioned from its original attachment on the pelvis to a new location on the femur. This adjustment allows the muscle to focus its action solely on the knee, effectively sacrificing its role in hip movement. Alternatively, the procedure may involve altering the muscle's function entirely, such as reattaching the rectus femoris to act as a knee flexor instead of an extensor. This flexibility in surgical approach allows for tailored solutions to specific muscular issues, ultimately enhancing the patient's quality of life and functional capabilities.
