Abstract
OBJECTIVE: The goal of the modified Ellison operation as a supplement to a conventional anterior cruciate ligament (ACL) reconstruction is to decrease anterolateral rotational instability of a knee joint after ACL rupture, to improve the stability and prevent ACL re-rupture. INDICATIONS: An ACL rupture with high risk of re-rupture (young age, high-performance sport, hyperlaxity, contralateral ACL rupture in history), increased subjective and objective anterolateral rotational instability of the knee after ACL rupture, ACL re-rupture. CONTRAINDICATIONS: Gonarthrosis, additive instabilities (e.g. posterolateral, medial), non-anatomical ACL reconstruction with persistent instability, general contraindications to surgery (e.g. infections), chronic irritation of the knee joint. SURGICAL TECHNIQUE: Supine position. Mark the typical landmarks. Incision from Gerdy's tubercle extending proximally along the iliotibial tract (ITT) to the lateral collateral ligament (approx. 5 cm). Incise the ITT in the line of its fibers about 10 mm anterior to its posterior border and continue the incision proximally to 5 mm proximal to the LCL. Make a parallel incision 10-12 mm anterior to the first incision. Use sharp subperiosteal dissection to elevate the strip of the ITT from Gerdy's tubercle. Secure the distal end of the ITT strip with a nonabsorbable suture (e.g. FiberWire No. 2, Arthrex, Naples, USA). Expose the LCL and pass the ITT strip deep to the LCL from proximal to distal and back to Gerdy's tubercle. Reattach the distal end of the strip of the ITT to its original position at Gerdy's tubercle with a bone anchor. The defect in the ITT can be closed with an absorbable suture (e.g. Vicryl, Ethicon, USA) in the proximal part. Layered closure. POSTOPERATIVE MANAGEMENT: Knee brace for at least 6 weeks, movement limitation of 0‑0-90° for 6 weeks, 2 weeks 20 kg partial weight bearing. RESULTS: A total of 36 patients (mean age 18.9 years) with a high risk of ACL re-rupture have been treated with ACL reconstruction and modified Ellison procedure. Follow-up over 2 years. Of the patients 35 returned to the previous sports level, 1 patient suffered a re-rupture, 2 patients had cyclops resection and 1 patient contralateral ACL rupture.
