Exercise-therapy and education for individuals one year after anterior cruciate ligament reconstruction: a pilot randomised controlled trial.

BMC Musculoskelet Disord 2021 Jan 11;22(1):64. Epub 2021 Jan 11.

La Trobe Sport & Exercise Medicine Research Centre, School of Allied Health, Humans Services and Sport, La Trobe University, Bundoora, 3086, Australia.

Background: Guided rehabilitation beyond 6-months is rare following anterior cruciate ligament reconstruction (ACLR), despite high prevalence of unacceptable symptoms and quality of life (QoL). Our primary aim was to determine the feasibility of a randomised controlled trial (RCT) evaluating a physiotherapist-guided intervention for individuals 1-year post-ACLR with persistent symptoms. Our secondary aim was to determine if a worthwhile treatment effect could be observed for the lower-limb focussed intervention (compared to the trunk-focussed intervention), for improvement in knee-related QoL, symptoms, and function.

Does sensorimotor function predict graft rupture, contra-lateral injury or failure to return to sports after ACL reconstruction? A protocol for the STOP Graft Rupture study.

BMJ Open 2021 01 8;11(1):e042031. Epub 2021 Jan 8.

Department of Community Medicine and Rehabilitation, Umeå Universitet, Umeå, Sweden.

Introduction: People with anterior cruciate ligament (ACL) reconstruction (ACLR) are at high risk of sustaining a graft rupture and/or contra-lateral ACL injury. The main factors that may predispose individuals for subsequent ACL injuries are, however, not established. To reduce the risk of reinjuries, it is of particular interest to identify modifiable risk-factors, for instance, those related to sensorimotor control which are responsive to training. Read More

Lateral displacement, sulcus angle and trochlear angle are associated with early patellofemoral osteoarthritis following anterior cruciate ligament reconstruction.

Knee Surg Sports Traumatol Arthrosc 2018 Sep 9;26(9):2622-2629. Epub 2017 May 9.

School of Allied Health, College of Science, Health and Engineering, La Trobe University, Bundoora, VIC, 3086, Australia.

Purpose: Patellofemoral osteoarthritis (PFOA) occurs in approximately half of anterior cruciate ligament (ACL)-injured knees within 10-15 years of trauma. Risk factors for post-traumatic PFOA are poorly understood. Patellofemoral alignment and trochlear morphology may be associated with PFOA following ACL reconstruction (ACLR), and understanding these relationships, particularly early in the post-surgical time period, may guide effective early intervention strategies.
