Early Knee Osteoarthritis Is Evident One Year Following Anterior Cruciate Ligament Reconstruction: A Magnetic Resonance Imaging Evaluation

Abstract

Objective. To determine the prevalence and factors associated with knee osteoarthritis (OA) defined by magnetic resonance imaging (MRI) and specific OA features on MRI 1 year after anterior cruciate ligament reconstruction (ACLR).Methods. Conclusion. OA 1 year following ACLR was more common than previously recognized, while being absent in uninjured control knees. The patellofemoral compartment seems to be at particular risk for early OA after ACLR, especially in men. The association with meniscectomy and BMI demonstrates the construct validity of MRI criteria.

Dynamic Single-Leg Postural Control Is Impaired Bilaterally Following Anterior Cruciate Ligament Reconstruction: Implications for Reinjury Risk

“…A flow chart reporting participant numbers and main reasons for exclusion appears elsewhere. 16 The ACLR was performed at a median of 3 months (interquartile range, 2-6 months) following injury (TABLE 1). Details of the surgical procedure and indications for concomitant meniscectomy have been published.…”

“…Details of the surgical procedure and indications for concomitant meniscectomy have been published. 16,17 All patients were referred to physical therapy for postoperative rehabilitation, including early weight bearing, range of movement, neuromuscular retraining, and a graduated return to sport.…”

Accelerated return to sport after anterior cruciate ligament injury: a risk factor for early knee osteoarthritis?

“…However, more advanced imaging modalities challenge this dogma. Within a year of ACL injury, femoral trochlear cartilage quality deteriorated rapidly,5 and in young adults 1 year post-ACLR, we reported a high prevalence (31%) of MRI-diagnosed OA, most frequently affecting the PFJ 6…”

“…Given the high rates of PFJ OA and symptoms independent of graft type,3 6 8 clinicians should recognise the contribution of the PFJ and include interventions that reduce patellofemoral pain during postoperative rehabilitation 9 10. Although randomised controlled trials are required to evaluate the effect of specific exercise modifications for the PFJ, adjustments such as closed kinetic chain exercises at <60° of knee flexion, combined with optimal quadriceps and hamstring activation minimise patellofemoral loads and may aid in limiting patellofemoral dysfunction 9…”

Retrospective Analysis of Non-Contact ACL Injury Risk: A Case Series Review of Elite Female Athletes

“…Anterior cruciate ligament (ACL) injuries continue to be one of the most debilitating injuries, in terms of the time lost from sport participation [1], the signi icant ongoing comorbidities which can be developed [2] and the heighten risk of further ACL injury [3]. Approximately 70% of ACL tears occur from a noncontact mechanism [4] with the research literature identifying both modi iable and non-modi iable risk factors predisposing the individual to increased risk of non-contact ACL injury [5,6].…”
