AI Article Synopsis
- The study investigates knee reinjuries and surgeries in patients after an acute ACL injury, comparing those who had ACL reconstruction (ACLR) to those who did not, over a two-year follow-up period.
- Out of 275 patients, 61% underwent ACLR, and 12% experienced reinjuries, with a notably higher incidence of reinjuries among the ACLR group.
- The findings suggest that ACLR did not significantly lower the risk of reinjuries or the need for additional surgeries, highlighting important considerations for treatment decisions.
Article Abstract
Purpose: To describe knee reinjuries and surgeries within 2 years after an acute anterior cruciate ligament (ACL) injury, in patients treated with or without ACL reconstruction (ACLR).
Methods: Two years follow-up of 275 patients (52% females, mean age 25.2 [SD 7.0] years) about knee reinjuries and surgeries were analysed from the prospective NACOX cohort study, aiming to describe recovery after an acute ACL injury treated according to clinical routine. Knee reinjury was defined as increase or new symptoms due to new trauma. At 2 years after injury, 169 (61%) had undergone an ACLR. Results are presented with descriptive statistics and risk ratios (RR).
Results: Thirty-two patients sustained reinjuries within 2 years; 6 in the non-ACLR group, and 26 in the ACLR group (7 before and 19 after ACLR). Twelve patients in the ACLR group sustained a graft rupture and three did an ACL revision. Patients with non-ACLR, aged 21-25 years, had a 5.9-fold higher risk for reinjury than those aged 15-20 years (RR 5.9 [1.3-26.9]; p = 0.012). Twenty-four patients had surgery in the non-ACLR group and 36 patients in the ACLR group (excluding primary ACLR), where six were before ACLR and 30 were after ACLR.
Conclusion: Twelve percent sustained a knee reinjury and 21% underwent knee surgery within 2 years after the index ACL injury. There was a higher reinjury incidence in the ACLR group, but no difference in incidence of surgeries. Thus, ACLR did not reduce the risk of traumatic reinjuries or surgeries, which is important for treatment decision considerations.

Comparison of Dynamic Postural Stability in Autografts Versus Allografts Following Anterior Cruciate Ligament Reconstruction With Remnant Preservation: A Prospective Study With 1-Year Follow-up.

Background: Graft selection is an important part of preoperative planning for anterior cruciate ligament reconstruction (ACLR). In addition, ACLR with the remnant preservation technique has recently gained attention due to potential benefit in bone-tendon healing, graft revascularization, and proprioceptive nerve remodeling. However, the ideal graft choice remains controversial, and there is limited research comparing autograft and allograft in ACLR with remnant preservation.

Objective: After anterior cruciate ligament reconstruction (ACLR), patients undergo specific changes in body and specific brain functions, which stem from neuroplasticity. In this study, we employed functional near-infrared spectroscopy (fNIRS) to investigate the characteristics of brain activation in patients after ACLR during a repetitive upstairs task, and compared them with healthy individuals. We aimed to provide a new theoretical basis for the changes in brain function after ACLR and neurorehabilitation of sports injuries.

Department of Physical Therapy, University of Delaware, Newark, Delaware, USA.
Background: Anterior cruciate ligament reconstruction (ACLR) often involves harvesting a bone-patellar tendon-bone (BPTB) autograft. How graft harvest affects tendon strain across the 3 distinct regions (medial, lateral, and central) is not known.
Purpose: To (1) quantify strain in the 3 regions of the patellar tendon during 60% of maximum voluntary isometric contraction (MVIC) in 90° of knee flexion and (2) assess how effort level in 2 different knee joint angles (60° and 90°) impacts strain in the medial and lateral regions of the patellar tendon, in 2 cohorts of patients after ACLR using a BPTB autograft (one group <24 months after surgery and another group ≥24 months after surgery).

Background: The individual variation in on-snow performance outcomes after anterior cruciate ligament (ACL) reconstruction (ACLR) in elite alpine ski racers has not been reported and may be influenced by specific injury characteristics.
Purpose: To report the performance statistics of elite ski racers before and after ACLR and to identify surgical and athlete-specific factors that may be associated with performance recovery.

Introduction: Arthroscopic Anterior Cruciate Ligament Reconstruction (ACLR) with internal bracing and augmentation using tape-type sutures (TTS) has gained popularity due to its biomechanical advantages. However, concerns have emerged regarding chronic reactive synovitis, which can lead to graft failure and the need for revision surgery. The purpose of this research is to determine the prevalence of chronic reactive synovitis after TTS-reinforced ACLR.
