“…Before this study, there were only another 2 published incidences of this happening: the first occurring 4 years postoperatively after a new knee trauma, and the second 10 years after ACLR and posterior cruciate ligament reconstruction. 15 , 26 More recently, Gawel et al 16 reported on a rare case of an adolescent patient who sustained a quadriceps tendon tear of unknown etiology 4 weeks after bone-tendon-bone (BTB) ACLR. Two patients in our cohort sustained traumatic extensor mechanism rupture after QTA ACLR.…”

Background: There are various reported complications after primary anterior cruciate ligament reconstruction (ACLR) necessitating additional surgery in skeletally immature patients, regardless of technique and autograft type. Purpose: To analyze the rate and type of complications encountered with soft tissue quadriceps tendon autograft (QTA) for ACLR in patients ≤18 years as well as the overall rate of second surgery, unrelated to the use of the QTA. Study Design: Case series; Level of evidence, 4. Methods: A total of 141 patients ≤18 years who underwent ACLR with a QTA and had minimum 6-month follow-up were included. All patients underwent ACLR by utilizing a full-thickness soft tissue QTA. Complications associated with the QTA harvest site and use of QTA were reported. Results: The mean age of the included cohort (84 men, 57 women) was 14.8 ± 1.6 years. The average follow-up was of 2.0 ± 1.2 years. A total of 30 (21%) patients had a subsequent complication that required surgical intervention; in 11 (8%) patients, the complication was specifically associated with the use of a QTA, whereas in 19 (13%) patients, the complication was related to the ACLR. In addition, 13 (9%) patients underwent a contralateral ACLR procedure. Of the QTA-related complications, 2 patients developed osteochondritis dissecans (OCD)-like lesions in the superior aspect of the patella, 2 patients had injured their quadriceps extensor mechanism and required surgical repair, and 8 patients had a subsequent procedure to remove nonabsorbable sutures used for donor site quadriceps tendon closure. One of the patients who underwent the removal of nonabsorbable sutures also had an arthroscopic debridement of patellar chondral damage. Conclusion: We reported complications encountered with soft tissue QTA for ACLR. The complication rate for QTA harvest was 8%. However, given that the removal of nonabsorbable sutures from the donor site was caused by the surgical technique used, the revised nonsuture-related complication rate for QTA graft harvest was 2%. Although the use of a QTA has recently gained popularity due to its high return-to-sport and low graft-failure rates, surgeons should be aware of the complications associated with using this graft type.
