ACL rehab

BACKGROUND: At the completion of formal rehabilitation after anterior cruciate ligament reconstruction, functional capacity is only restored in a small proportion of affected individuals. Therefore, the end of formal rehabilitation is not the end of functional rehabilitation. OBJECTIVE: To compare adherence to and effectiveness of a late-stage rehabilitation programme with usual care after anterior cruciate ligament (ACL) reconstruction. METHODS: This prospective, double-blind, multicentre, parallel group, randomised controlled trial, included people aged 18 to 35 years after formal rehabilitation completion (mean [SD] 241 [92] days post-reconstruction)...

PURPOSE: To assess how intraoperative macroscopical anterior cruciate ligament (ACL) findings affect perioperative procedures, biomarkers, and postoperative anterior-posterior (AP) laxity and range of motion (ROM) after cruciate-retaining (CR) total knee arthroplasty (TKA) and to determine how chronic ACL deficiency may affect postoperative inflammatory biomarker, AP laxity, and ROM. METHODS: A total of 121 patients with varus knee osteoarthritis without a history of ACL injury who underwent ATTUNE® (DePuy Synthes, Warsaw, IN) CR TKA were analyzed...

CONTEXT: Among many unanticipated changes, access to rehabilitation was disrupted during the onset of the COVID-19 pandemic. It is unclear how the timing of late-stage rehabilitation following anterior cruciate ligament with surgical reconstruction (ACLR) during the initial months of the pandemic affected outcomes. The purpose of this study was to compare physical performance outcome measures in patients following ACLR prior to and following COVID-19-related restrictions. DESIGN: Retrospective cohort study...

UNLABELLED: An elastic band wrapped around the distal thighs has recently been proposed as a method for reducing dynamic knee valgus (medial movement of the knee joint in the frontal/coronal plane) while performing squats. The rationale behind this technique is that, by using an external force to pull the knees into further knee valgus, the band both exaggerates the pre-existing movement and provides additional local proprioceptive input, cueing individuals to adjust their knee alignment...

Background and Objectives: An effective post-injury training program is essential to regain performance and fulfill criteria for return to sport for team sport athletes following anterior cruciate ligament (ACL) reconstruction. The aim of this study was to compare the effects of 6 weeks of eccentric-oriented strength training vs. traditional strength training during the late-stage ACL-rehab phase on leg strength and vertical and horizontal jumping performance in professional team sport athletes. Materials and Methods: Twenty-two subjects (14 males, 8 females, age 19...

This clinical commentary will address five key concepts that can be used by clinicians as criteria for selecting lower extremity weight bearing exercises (WBE) and non-weight bearing exercises (NWBE) employed for cruciate ligament and patellofemoral rehabilitation. The following will be discussed for both cruciate ligament and patellofemoral rehabilitation: 1) Knee loading varies between WBE and NWBE; 2) Knee loading varies with technique variations within WBE and NWBE; 3) Knee loading varies between different WBE; 4) Knee loading varies as a function of knee angle; and 5) Knee loading increases with increased knee anterior translation beyond toes...

The anterior cruciate ligament (ACL) is the most studied ligament in the knee and one of the most studied topics in orthopaedics, with little consensus on best options for surgical technique or graft choice. While there is little question that physical rehabilitation is one of the most important variables in the episode of care before and after ACL reconstruction (ACLR), recent research surveying orthopaedic surgeons demonstrates no consensus of how to rehab ACLR patients and how to get them to return to sport safely and quickly...

CONTEXT: Up to 90% of pediatric athletes return to sport (RTS) after anterior cruciate ligament reconstruction (ACL-R); however, <50% RTS at the same level and second ACL injury rates are up to 32%. OBJECTIVES: (1) Determine which physical and patient-reported outcome measures guide clinical decision-making on RTS in pediatric athletes after ACL-R and (2) present a framework with insights from cognitive and neurophysiological domains to enhance rehabilitation outcomes...

PURPOSE: The purpose of this study was to evaluate whether harvesting a second graft from the ipsilateral extensor mechanism adversely affects clinical outcomes in revision anterior cruciate ligament (ACL) reconstruction. METHODS: A retrospective review of 34 patients undergoing revision anterior cruciate ligament (ACL) reconstruction with either quadriceps tendon (QT) autograft or bone-tendon-bone (BTB) autograft was conducted. Patients with two grafts (BTB+QT) from the extensor mechanism were matched based on age, laterality, and sex to patients who had primary reconstruction with hamstring (HS) autograft followed by revision with either BTB or QT autograft (HS+QT/BTB)...

The knee is one of the most frequently affected joints in sports trauma, and anterior cruciate ligament (ACL) injury and meniscal tears are the most common lesions. ACL reconstruction (ACLR) remains the treatment of choice for patients willing to return to their previous activity. There are different surgical techniques and different possible usable grafts. The graft used for ACLR surgery undergoes a bone incorporation process and an intra-articular remodelling named ligamentization until it reaches characteristics similar to the native ligament...

BACKGROUND: Determining readiness to return to sport after anterior cruciate ligament (ACL) reconstruction is challenging. OBJECTIVES: To develop models to predict initial (directly after rehabilitation) and sustainable (one year after rehabilitation) return to sport and performance in individuals after ACL reconstruction. METHODS: We conducted a multicentre, prospective cohort study and included 208 participants. Potential predictors - demographics, pain, effusion, knee extension, muscle strength tests, jump tasks and three sport-specific questionnaires - were measured at the end of rehabilitation and 12 months post discharge from rehabilitation...

BACKGROUND: Current evidence demonstrates that few patients complete anterior cruciate ligament reconstruction rehabilitation according to evidence-based guidelines. It is important to investigate the viewpoints of our patients to identify patient-reported barriers and facilitators of anterior cruciate ligament reconstruction rehabilitation. Qualitative analysis can provide insight into potential methods for improving the delivery of rehabilitation services. METHODS: In this qualitative study, utilising a social constructionism orientation, viewed through the social phenomenological lens, three focus groups were conducted with individuals 1-20 years post anterior cruciate ligament reconstruction (n = 20, 9 males, 11 females, mean 6...

Anterior cruciate ligament (ACL) tears are prevalent sport-related injuries that result in protracted quadriceps atrophy and weakness despite surgical reconstruction and physical therapy. Vitamin D and its receptor are integral for skeletal muscle development and homeostasis. In addition, vitamin D status is positively associated with muscle size and strength. If the vitamin D receptor and related enzymes are upregulated with ACL injury and reconstruction, then overall vitamin D status may be an important effector of recovery...

CONTEXT: Lower-extremity loading patterns change after anterior cruciate ligament reconstruction (ACLR). However, there is limited research regarding energy absorption contribution (EAC) of athletes following ACLR who reinjure their ACL and those who do not. EAC can be utilized as a measure of joint loading during tasks. DESIGN: Cross-sectional study. METHODS: Three groups of individuals (13 in each group) with matched age, sex, height, weight, and sports were enrolled...

BACKGROUND: Functional rating scales allow clinicians to document and quantify alterations and progression of recovery processes. There is neither awareness of numerous knee scales nor are they easy to find or compare to select the most suitable. OBJECTIVES: We aimed to compile validated knee functional rating tools and analyze the methodological quality of their validation studies. Also, we aimed to provide an operational document of the outcome measures addressing descriptions of parameters, implementations, instructions, interpretations and languages, to identify the most appropriate for future interventions...

BACKGROUND: The goal of a rehabilitation programme after anterior cruciate ligament (ACL) reconstruction is to manage a patient's goals and expectations (i.e., returning to physical activities and sports) while minimizing the risk of new injury, particularly a new ACL injury. Although general rehabilitation programmes have been proposed, some factors can lead to adapting each programme to each patient. OBJECTIVE: To describe how different variables, including surgical techniques, sports participation, psycho-social and contextual factors can modify the rehabilitation programme...

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction requires an extended period of postoperative rehabilitation. Psychological factors can affect recovery after surgery. Study of psychological factors is still limited to self-motivation, fear and pain. Study of personality traits associated with early rehabilitation outcome after ACL reconstruction is scarce. OBJECTIVE: We aimed to explore the effect of personality traits on early rehabilitation after ACL reconstruction and provide a reference for clinicians in designing a personalized rehabilitation plan...

BACKGROUND: After anterior cruciate ligament reconstruction (ACLR), the decision to allow a return to running is empirical, and the post-operative delay is the most-used criterion. The Quadriceps isokinetic-strength Limb Symmetry Index (Quadriceps LSI), with a cutoff of 60%, could be a useful criterion. OBJECTIVE: To determine the association between a Quadriceps LSI≥60% and return to running after ACLR. METHODS: Over a 10-year period, we retrospectively included 470 patients who underwent ACLR...

PURPOSE: To evaluate and compare changes in quadriceps and hamstring strength and single-leg-hop (SLH) test performance over the first 24 postoperative months in patients who underwent anterior cruciate ligament reconstruction (ACLR) with bone-patellar tendon-bone (BPTB) or hamstring tendon (HT) autografts and followed either a standard or an accelerated rehabilitation protocol. METHODS: A total of 160 patients undergoing ACLR were randomised in four groups depending on the graft that was used and the rehabilitation protocol (40 BPTB/standard rehab, 40 BPTB/accelerated rehab, 40 HT/standard rehab, 40 HT/accelerated rehab)...

PURPOSE: To investigate the information quality available on YouTube regarding rehabilitation and return to sport (RTS) after anterior cruciate ligament reconstruction (ACLR). METHODS: By use of The Onion Router software and predefined search terms, 140 YouTube videos regarding rehabilitation and RTS after ACLR were systematically included. Three scoring systems were used to analyze the included videos: (1) Journal of the American Medical Association (JAMA) benchmark criteria; (2) Global Quality Score (GQS); and (3) self-developed scores for rehabilitation after ACLR and RTS after ACLR, following American Academy of Orthopaedic Surgeons guidelines and current evidence...
