ABSTRACT
PURPOSE: The aim of this study was to evaluate the clinical results, return to sport and complications after anterior cruciate ligament reconstruction (ACLR) associated with lateral extra-articular tenodesis using continuous plasty with an iliotibial band. METHODS: This was a prospective multicentre study involving 186 patients who had surgery for anterior cruciate ligament (ACL) rupture. Patients with multiligament ruptures and revision surgery were excluded from the study. All patients included were involved in pivoting sports and wished to resume their activity after surgery. Patients were assessed at a minimum 2-year follow-up using functional and psychological questionnaires (subjective International Knee Documentation Committee [IKDC], Tegner, Lysholm and ACL-RSI scores), ligament assessment including instrumented laxity measurement (Rolimeter), Lachman test and pivot shift and isokinetic testing. Return to sport was assessed using a questionnaire, and complications and repeat surgeries were recorded. RESULTS: At a mean follow-up of 43.1 months, the subjective IKDC, Lysholm, ACL-RSI and objective IKDC scores were significantly improved (59.8 vs. 94.5 p < 0.0001, 75 vs. 99 p < 0.0001, 60 vs. 93 p < 0.0001, IKDC A 0% vs. 72%, B 12% vs. 27%, C 60% vs. 1% D 28% vs. 0% p < 0.0001). The Tegner activity level was 9 (3-10) before the accident and 9 (3-10) at the last review. Seventy-six percent of the patients had returned to sports at the same level. The differential laxity was 6.6 mm (±1.7) preoperatively and 1.1 mm (±1.4) postoperatively. Additionally, 97% were equal in pivot shift at the last follow-up. At the 6-month isokinetic assessment, the muscle strength recovery for the quadriceps and hamstring was over 85% compared with the healthy side for 79% and 70% of the patients, respectively. Ten patients had graft rupture (5.6%). Four (2.4%) patients had a contralateral ACL rupture, and seven (4%) underwent a reoperation with meniscectomy. CONCLUSION: Anterior ligament reconstruction with lateral extra-articular tenodesis using a continuous strip of iliotibial band enables 76% of patients in a population with a high demand for sports to resume their activities at the same level. The clinical results and complication rates, particularly reruptures (5.6%), were similar to those of other techniques involving lateral extra-articular tenodesis. LEVEL OF EVIDENCE: Level II.
ABSTRACT
BACKGROUND: The aim of this cadaveric study was to assess the technical feasibility of inserting a novel interpositional pyrolytic carbon coated implant in the first MTP joint, determine the best surgical procedure for the implantation, and evaluate the dynamic behavior of the joint after surgery. METHODS: The marble implant was inserted in the first metatarsophalangeal joint of five pairs of cadaveric feet using two different surgical approaches, dorsal and medial, for each pair. The stability and mobility of the feet before and after implantation, as well as the relationship between the implant and the sesamoids, were assessed by static and dynamic fluoroscopy. RESULTS: After implantation, the stability was perfect in all positions and the mobility was conserved. There were no conflicts between the sesamoids and the implant during the movement of the first metatarsophalangeal joint. Both the dorsal and the medial surgical approaches led to similar findings. CONCLUSION: To our knowledge, this is the first anatomic evaluation of this type of implant. Whereas the results of the technique obtained on cadaveric feet were satisfactory, caution has to be applied to trying to apply this procedure to the living patient.

Anterior cruciate ligament reconstruction in children with open physes is still a topic of debate. We report a unique case of growth disturbance in valgus and flexion of the distal femoral epiphysis, after an ACL reconstruction in a 14.5-year-old boy. The Clocheville technique using the patellar tendon was performed. The femoral tunnel and tibial groove were both positioned above the growth plates. Eighteen months after ACL reconstruction, the patient had to be re-operated on for a valgus and flexion deformity of the femoral epiphysis. The clinical, radiological and aesthetic results were satisfactory. The angular deformity was caused by the fact that either the femoral tunnel was too close to the posterolateral femoral growth plate or an excessive eccentric traction of the graft in relation to the central point of the knee.
