Purpose. To compare the results of anterior cruciate ligament (ACL) reconstructions using either a patella-tendon autograft or a semitendinosus-tendon autograft. Methods. Based on surgeon experience and preference, 68 patients underwent ACL reconstruction using either a quadruple-strand semitendinosus autograft (n=34) or a central one-third bone-patella tendon-bone autograft (n=34). Each patient was assessed preoperatively and postoperatively at 3, 6, and 24 months using the International Knee Documentation Committee (IKDC) knee score, Biodex muscle strength and endurance testing, and the KT1000 instrumented arthrometer test of knee laxity to anterior translation. All assessments at the 2-year follow-up were performed by the same physician and physiotherapist. Results. While ACL reconstruction improved knee stability and IKDC knee scores significantly, there was no statistically significant difference between semitendinosus- and patella-tendon autograft reconstructions in terms of long-term knee score or laxity to anterior translation. Semitendinosus graft reconstruction was associated with less donor-site morbidity and hamstring weakness. Meniscectomy was associated with poorer long-term knee scores. Conclusion. ACL reconstruction is associated with a significantly better IKDC knee score and laxity measurement at 2-year follow-up. However, we were unable to demonstrate a significantly better long-term outcome in knee score or laxity to anterior translation with either a patella-tendon autograft or a semitendinosus-tendon autograft.

Background: To reduce the rate of anterior cruciate ligament (ACL) graft rupture, recent surgeries have involved anterolateral ligament reconstruction (ALLR). This reconstruction procedure harvests more knee flexor muscle tendons than isolated ACL reconstruction (ACLR), but its influence on knee muscle strength recovery remains unknown. This study aimed to assess the influence of ALLR with a gracilis graft on the strength of the knee extensor and flexor muscles at 6 months postoperatively. Hypothesis: The additional amount of knee flexor harvest for ALLR would result in impairment in knee flexor muscle strength at 6 months postoperatively. Study Design: Retrospective cohort study. Level of Evidence: Level 2. Methods: A total of 186 patients were assigned to 2 groups according to the type of surgery: ACL + ALLR (graft: semitendinosus + gracilis, n = 119) or isolated ACLR (graft: semitendinosus, n = 67). The strength of the knee extensor and flexor muscles was assessed using an isokinetic dynamometer at 90, 180, and 240 deg/s for concentric and 30 deg/s for eccentric contractions and compared between groups using analysis of variance statistical parametric mapping. Results: Regardless of the surgery and the muscle, the injured leg produced significantly less strength than the uninjured leg throughout knee flexion and extension from 30° to 90° for each angular velocity (30, 90, 180, and 240 deg/s). However, the knee muscle strength was similar between the ACL + ALLR and ACLR groups. Conclusion: The addition of ALLR using the gracilis tendon during ACLR does not alter the muscle recovery observed at 6 months postoperatively. Clinical Relevance: Although more knee flexor muscle tendons were harvested in ACL + ALLR, the postoperative strength recovery was similar to that of isolated ACLR.

The aim of our study was to review the long term clinical and radiological (MRI) outcomes of adult patients who underwent ACL reconstruction as children or adolescent with emphasize to the features of growth disturbance, angular deformity, meniscal and cartilage damage and revision rate We retrospectively evaluated patient who underwent ACL reconstruction in our clinic with arthroscopic transepiphyseal technique using hamstrings graft in childhood or adolescence between the years 1997 and 2009. A total of 43 Patients were assessed. 25 male and 18 female. The average age at time of surgery was 13,5 years (8 - 16 y.), at time of assessement 22,4 years (18 - 30 y.) . The mean follow up was 10 years (4 - 16 years). The physical development of the patients was assessed with the Lysholm score and the Cincinnati Knee score scale, their satisfaction was recorded on the basis of the IKDC subjective knee evaluation form and the Tegner activity score . Leg deformity or leg length discrepancy was evaluated clinically by the observers. The instrumented Lachman test using KT1000 and manual Pivot shift test was performed to assess knee stability. MRI was used to detect graft integrity, cartilage and meniscal damages. No significant leg deformities or leg length discrepancy had been detected. The average Lysholm score was 91 points (83 - 100), the Cincinnati Knee Score was 90,4 (79 - 100) points on average . The mean IKDC score was 92 points (82 -100). The Tegner-Activity-Score changed from preop 6,8 (2-10) to post op 5,8 (2-9). 2 Patient underwent revision ACL reconstruction due to rerupture (3 and 9 years post op). 2 Patients underwent meniscal surgery during follow up (1 resection and one refixation). KT1000 evaluation showed 67% excellent, 21% good and in 12% bad results. The MRI scan showed 42 intact grafts and one unverifiable graft. One patient with cartilage damage up to 3° (ICRS), 3 patients with meniscal degeneration up to grade 2. Each patient showed a free range of motion Our data underlines that transepiphyseal ACL reconstruction in children and adolescent with hamstrings is a save procedure leading to good long term results without causing angular deformity or growth disturbance
