STUDY DESIGN: Comprehensive review and meta-analysis. BACKGROUND: The recovery in rapid force production measured as the rate of force development (RFD) is not clear after anterior cruciate ligament reconstruction (ACLR). OBJECTIVES: To evaluate (a) time-course change of between-limb asymmetries in isometric knee extension/flexion RFD in individuals post-ACLR and (b) differences in RFD between individuals post-ACLR and healthy controls. METHODS: A literature search of Web of Science, SPORTDiscus, PubMed-MEDLINE, and ScienceDirect identified 10 eligible studies (n = 246) assessing RFD after ACLR...

OBJECTIVE: To compare the effects of conventional (constant load) eccentric training and isokinetic eccentric training on quadriceps muscle mass, strength and functional performance in recreational athletes following anterior cruciate ligament (ACL) reconstruction. METHODS: Thirty recreational male athletes (25 years old) undergoing ACL reconstruction received a standard rehabilitation program. Volunteers were randomized to conventional group (CG; n = 15) or isokinetic group (IG; n = 15) to be engaged in a 6-week (2 sessions/week) quadriceps eccentric training program at the extensor chair or at the isokinetic dynamometer, respectively...

BACKGROUND: Many studies have investigated factors that predict a return to sport participation after anterior cruciate ligament (ACL) reconstruction, but it is unclear whether the same factors are associated with a return to preinjury level of sport performance. PURPOSE: To identify factors that contribute to an athlete's return to preinjury level of performance after ACL reconstruction. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A cohort of 222 patients (132 male, 90 female) who had ACL reconstruction surgery and completed a 12-month postoperative assessment were followed out to a mean 3 years (range, 2-4 years) to determine whether they had returned to their self-reported preinjury levels of sport performance...

BACKGROUND: The incidence of meniscocapsular junction tears of the medial meniscus posterior horn, known as ramp lesions , is reported to be 9.3% to 23.9%. However, these lesions are not consistently diagnosed with routine arthroscopic exploration and magnetic resonance imaging (MRI). PURPOSE: To determine risk factors associated with ramp lesions in anterior cruciate ligament-injured knees. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

BACKGROUND: We implemented a blood flow restriction resistance training (BFR-RT) intervention during an 8-week rehabilitation programme in anterior cruciate ligament reconstruction (ACLR) patients within a National Health Service setting. OBJECTIVE: To compare the effectiveness of BFR-RT and standard-care traditional heavy-load resistance training (HL-RT) at improving skeletal muscle hypertrophy and strength, physical function, pain and effusion in ACLR patients following surgery...

BACKGROUND: Knee brace has been commonly used as a device to protect the graft after reconstruction of anterior cruciate ligament (ACL). Studies have focused on the effects of braces after ACL reconstruction, and controversial results were reported. The current meta-analysis was conducted to identify whether knee braces could provide superior clinical outcomes on knee functional scores and stability evaluations. HYPOTHESIS: Knee braces could not provide superior clinical outcomes on knee functional scores and stability evaluations...

Background: Outcomes after anterior cruciate ligament reconstruction (ACLR) are not uniformly good and are worse among young female athletes. Developing better rehabilitation and return-to-sport training programs and evaluating their outcomes are essential. Purpose: (1) Test the effect of strength, agility, plyometric, and secondary prevention (SAPP) exercises with and without perturbation training (SAPP + PERT) on strength, hops, function, activity levels, and return-to-sport rates in young female athletes 1 and 2 years after ACLR and (2) compare 2-year functional outcomes and activity levels among young female athletes in the Anterior Cruciate Ligament Specialized Post-Operative Return-to-Sports (ACL-SPORTS) trial to homogeneous cohorts who completed criterion-based postoperative rehabilitation alone (Multicenter Orthopaedic Outcomes Network [MOON]) and in combination with extended preoperative rehabilitation (Delaware-Oslo)...

BACKGROUND: A return to running after anterior cruciate ligament reconstruction (ACL-R) is critical to the clinical success of any cutting and pivoting athlete who wishes to return to sport. Knowledge of specific alterations during running after ACL-R is required to optimise rehabilitation for improving outcomes and long-term disability. OBJECTIVE: The objective of this systematic review was to summarise kinematic, kinetic and muscle activation data during running after ACL-R and the intrinsic factors (e...

PURPOSE: To assess the percentage of patients achieving symmetrical knee function 6 months after primary anterior cruciate ligament (ACL) reconstruction (ACLR) and to identify factors affecting its achievement, in a large cohort. METHODS: Data were extracted from our clinic database. Patients who underwent primary ACLR from 2000 to 2015 and were assessed with the isokinetic quadriceps and hamstring muscles strength tests and single-leg-hop test at the 6-month follow-up were included in the study...

J Strength Cond Res 35(3): 769-775, 2021-Poor quadriceps strength has been associated with poor outcome after anterior cruciate ligament (ACL) reconstruction (ACLR). This study aims to assess quadriceps strength, muscle inhibition, and hop test performance in professional soccer players after ACLR. Fifteen professional soccer players (age 22...

PURPOSE: To examine any association between the timing of ipsilateral postoperative corticosteroid injection following simple knee arthroscopy and infection. METHODS: Private payer (PP) and Medicare (MC) national insurance databases were queried for patients who underwent simple arthroscopic knee procedures. Patients undergoing concomitant open or more complex procedures with grafts were excluded. Patients who underwent ipsilateral corticosteroid injections within 2, 4, 6, and 8 weeks postoperatively were then identified...

BACKGROUND: With sports specialization and level of competition on the rise, anterior cruciate ligament reconstruction (ACLR) in athletes under the age of 20 has increased significantly in recent years. Reports have demonstrated that the revision ACLR rate is higher and return to sport (RTS) rate is lower in this population. PURPOSE: To evaluate the 2-year clinical outcomes of 3 cohorts of primary ACLR in pediatric and adolescent athletes under the age of 20 based on skeletal age with a focus on RTS and the incidence of second surgery...

BACKGROUND: There is limited information about patient expectations regarding return to sport after anterior cruciate ligament reconstruction (ACLR). While it has generally been assumed that patients expect to return, it has also been acknowledged that expectations may change after surgery. PURPOSE: To investigate return-to-sport expectations before and after ACLR and determine factors associated with changed expectations. STUDY DESIGN: Cohort study; Level of evidence, 2...

BACKGROUND: Anterior cruciate ligament (ACL) injury has a significant psychological effect, and a negative psychological state is a commonly cited reason for a reduction or cessation of sports participation after ACL reconstruction (ACLR) surgery. PURPOSE: To identify factors that contribute to an athlete's psychological readiness to return to sport (RTS) after ACLR. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A cohort of 635 athletes (389 male, 246 female) who underwent ACLR and had been cleared to RTS completed the Anterior Cruciate Ligament-Return to Sport After Injury (ACL-RSI) scale at an average 12 months (range, 11-24 months) after surgery...
