摘要

Objective

Harvesting a strip from the distal rectus femoris tendon as an autograft for ligament reconstruction of the knee or other joints.

Indications

Ligament reconstructions of the knee, both primary and revision procedures.

Contraindications

Relative: athletes in jumping sports requiring rapid recovery of explosive strength.

Surgical technique

Palpation of the distal quadriceps tendon at the “fusion zone,” approximately 5 cm proximal to the superior patellar pole. A 3–4 cm longitudinal skin incision is made at the junction of the lateral and middle third or centrally. The quadriceps tendon is exposed and identified proximally. After identification, two parallel incisions create an 8–10 mm wide graft. The tendon strip is mobilized with a clamp just above the fusion zone and separated from the deeper layers. Distal detachment of the graft can be performed either (a) with a scalpel after whipstitching of the free end or (b) with a closed tendon stripper following proximal release under tension. The preparation is then extended proximally by 7–8 cm with scissors and bluntly separated from deeper layers with the index finger. An open or closed tendon stripper (8–9 mm) is advanced proximally with the knee in 20° flexion until complete graft harvest. Rotational movements should be avoided.

Postoperative management

Rehabilitation follows the protocol of the corresponding ligament reconstruction. No specific measures are required for the donor site.

Results

Radiological assessment demonstrated a mean distal rectus femoris tendon length of 39 cm (32–47 cm). In cadaveric studies, the technique was feasible and reproducible. Clinically, the graft was used in 103 patients, with a mean graft diameter of 8.3 mm. In a few cases, hamstring augmentation was required. Complications such as arthrofibrosis or donor-site hematoma were rare and successfully treated. External studies confirmed the suitability of the rectus femoris tendon, particularly for revision anterior cruciate ligament reconstruction.
