Clinical and radiological outcome after anterior cruciate ligament reconstruction using the T-lock Osteotrans resorbable tendon anchor: early experience and midterm follow-up.

PURPOSE: Reconstruction of the Anterior cruciate ligament (ACL) using tendon grafting is an established method for restoring knee function and stability. Multiple methods are established for graft fixation. Several involve anchoring the autograft distant to the joint with hardware that remains implanted. This study reports the first early to midterm results in patients who received ACL reconstruction (ACLR) using the T-Lock Osteotrans femoral near joint fixation method with a tibial fixation using the BioactIF Osteotrans interference screw. METHODS: This consecutive prospective series included 20 Patients (14 Male, 6 Female) with a primary ACL rupture. All patients were treated with an ACLR using a semitendinosus autograft fixated with the T-Lock Osteotrans and were followed-up postoperatively. The following parameters were assessed: Side-to-side difference of the posterior-anterior translation measured using the KT-1000 arthrometer, Tegner activity score, Lysholm score, IKDC subjective knee evaluation form. Magnetic resonance imaging (MRI) was done to assess tunnel enlargement and integrity of the anchoring device. RESULTS: The average follow-up duration was 2 years (range 1-4.2 years). One patient was lost to follow-up. Two Patients suffered a traumatic ACL re-rupture 2 years postoperatively and received a 2-stage revision ACLR. Difference in the posterior-anterior translation was 1.8 mm (range 0-5). The median Tegner score was 6 (range 4-10) and 9 patients (45%) returned to their preinjury level of activity. The mean IKDC subjective knee evaluation form scored 91 points (range 77-100). The mean Lysholm score was 86 points (74-96). All mentioned scores were significantly better compared to preoperative values. No relevant tunnel enlargement was seen on MRI. The anchoring device was evaluated to be intact in all patients. CONCLUSION: ACLR with the aforementioned procedure leads to good clinical and radiological outcome.

[Joint pain and consumption of analgesics among young elite athletes : Nationwide data from youth basketball]. / Gelenkschmerzen und Analgetikakonsum bei jungen Leistungssportlern : Bundesweite Daten aus dem Jugendbasketball.

BACKGROUND: Joint pain may be an early indicator of biomechanical stress. During adolescence the physical development, including the development of the musculoskeletal system, is still ongoing and joint pain requires special attention, especially among young athletes. OBJECTIVE: Young athletes from the highest national basketball leagues in Germany were questioned about prevalence, location, context and coping strategies concerning joint pain. MATERIAL AND METHODS: Data were derived from the German "Adolescents' and Childrens' Health in Elite Basketball study" (ACHE study). Analyses were based on an online survey of 182 elite basketball players between 13 and 19 years of age from 46 German teams, conducted between April 2016 and June 2016. RESULTS: In the highest German leagues 2 out of 3 players suffered from joint pain at the time of the survey (7-day prevalence 64.6%). Pain in the lower extremities occurred most frequently. The 7­day prevalence for knee and leg pain reached up to 40% and foot pain up to 21%. For 84% of all players, occasional consumption of analgesics was the norm and 40% took them frequently. The consumption of several medicinal substances, especially of cyclooxygenase inhibitors, such as ibuprofen and diclofenac, is widespread among adolescent elite basketball players as 1 out of 7 athletes (13%) used medicinal substances despite being pain-free and 5% used it prophylactically with the purpose of preventing pain. CONCLUSION: From the point of view of pain medicine, it is not only the high prevalence of pain that is remarkable but also the widespread use of analgesics without a prescription and the misguided conception of adolescent competitive athletes that such medications have preventive effects.
