Knee reinjury after ACL reconstruction is common and increases the risk of osteoarthritis. There sparse evidence to guide return sport (RTS) decisions in this population.To assess relationship between knee (1) level I sports, (2) timing RTS (3) function prior return.106 patients who participated pivoting sports prospective 2-year cohort study. Sports participation were recorded monthly. was assessed with Outcome Survey-Activities Daily Living Scale, global rating scale function, quadriceps...
Background: Single-legged hop tests are commonly used functional performance measures that can capture limb asymmetries in patients after anterior cruciate ligament (ACL) reconstruction. Hop hold potential as predictive factors of self-reported knee function individuals ACL Hypothesis: conducted preoperatively would not and 6 months reconstruction predict (International Knee Documentation Committee [IKDC] 2000) 1 year Study Design: Cohort study (prognosis); Level evidence, 2. Methods: One...
Background No gold standard exists for identifying successful outcomes 1 and 2 years after operative non-operative management of anterior cruciate ligament (ACL) injury. This limits the ability a researcher clinicians to compare contrast results interventions. Purpose To establish consensus based on expert measures that define ACL injury or reconstruction. Methods Members international sports medicine associations, including American Orthopaedic Society Sports Medicine, European...
Background: Impaired quadriceps muscle strength after anterior cruciate ligament reconstruction (ACLR) is associated with worse clinical outcomes and a risk of reinjuries. Yet, we know little about in patients reconstructed tendon (QT) graft, which increasing popularity worldwide. Purpose: To describe compare isokinetic undergoing ACLR QT, hamstring (HT), or bone–patellar tendon–bone (BPTB) autograft. Study Design: Cross-sectional study; Level evidence, 3. Methods: We included QT grafts (n =...
Background Preoperative knee function is associated with successful postoperative outcome after anterior cruciate ligament reconstruction (ACLR). However, there are few longer term studies of patients who underwent progressive preoperative and rehabilitation compared to usual care. Objectives To compare 2 year patient-reported outcomes (PROs) in undergoing at a sports medicine clinic Methods We included aged 16–40 years primary unilateral ACLR. The Knee Injury Osteoarthritis Outcome Score...
In October 2017, the International Olympic Committee hosted an international expert group of physiotherapists and orthopaedic surgeons who specialise in treating researching paediatric ACL injuries. Representatives from American Orthopaedic Society for Sports Medicine, European Paediatric Society, Traumatology, Knee Surgery & Arthroscopy, Arthroscopy Pediatric North America Sociedad Latinoamericana de Artroscopia, Rodilla y Deporte attended. Physiotherapists with clinical research experience...
Background: Previous studies have found significant predictors for functional outcome after anterior cruciate ligament (ACL) reconstruction; however, examining in nonoperatively treated individuals are lacking. Hypothesis: Single-legged hop tests predict self-reported knee function (International Knee Documentation Committee [IKDC] 2000) ACL-injured 1 year baseline testing. Study Design: Cohort study (prognosis); Level of evidence, 2. Methods: Ninety-one patients with an ACL injury were...
While there are many opinions about the expected knee function, sports participation, and risk of reinjury following nonsurgical treatment injuries anterior cruciate ligament (ACL), is a lack knowledge clinical course compared with that after surgical treatment.This prospective cohort study included 143 patients an ACL injury. Isokinetic extension flexion strength patient-reported function as recorded on International Knee Documentation Committee (IKDC) 2000 form were collected at baseline,...
Study Design Cohort study, cross-sectional. Objectives To determine if self-reported knee function assessed with the International Knee Documentation Committee 2000 Subjective Form (IKDC 2000) could discriminate between successful and nonsuccessful performance on return-to-activity criteria (RTAC) tests after anterior cruciate ligament (ACL) reconstruction. Background Selecting appropriate performance-based patient-reported that can detect side-to-side asymmetries, assess global function, a...
Background: Patients usually return to pivoting sports between 6 months and 1 year after anterior cruciate ligament (ACL) reconstruction, but no matched study has so far examined 1-year sport rates in nonoperatively operatively treated ACL-injured patients. Hypothesis: Anterior ligament-injured patients following a nonoperative treatment course, including recommendation of activity modification, will have lower than baseline testing/surgery, when by preinjury activity, age, sex. Study...
Background: Rehabilitation before anterior cruciate ligament (ACL) reconstruction (ACLR) is effective at improving postoperative outcomes least in the short term. Less known about effects of preoperative rehabilitation on functional and return-to-sport (RTS) rates 2 years after reconstruction. Purpose/Hypothesis: The purpose this study was to compare ACLR a cohort that underwent additional rehabilitation, including progressive strengthening neuromuscular training impairments were resolved,...

Objective To elucidate the relationships between age, return to level I sport (RTS) within first postoperative year, passing RTS criteria and second anterior cruciate ligament (ACL) injury. Methods In a prospective cohort study, 213 athletes were followed for 2 years after ACL reconstruction record injuries. Independent variables year (vs later or no RTS). We defined as ≥90 on Knee Outcome Survey — Activities of Daily Living Scale, global rating scale function quadriceps strength/hop test...
Some athletes demonstrate excellent dynamic stability after anterior cruciate ligament (ACL) rupture and return to sport without ACL reconstruction (ACLR) (copers). Others persistent instability despite rehabilitation (noncopers) require surgical stabilization. Testing determine coper classification can identify potential copers early rupture. It is unclear how changes a brief intervention relates long-term outcomes.(1) To evaluate the consistency of (potential vs noncoper) before...
Clinicians need thresholds for the Patient Acceptable Symptom State (PASS) and Treatment Failure to interpret group-based patient-reported outcome measures after anterior cruciate ligament (ACL) injury. Validated that are crucial accurately discerning patient symptom state facilitating effective interpretation have not been determined long-term follow-up ACL
More than 50% of highly active patients with an anterior cruciate ligament (ACL) injury who choose nonsurgical treatment (active rehabilitation alone) have successful 2-year outcomes and comparable knee function to uninjured population. Early predictive factors for a outcome may aid decision making in this population.To identify early predictors those ACL injury.Cohort study; Level evidence, 2.This prospective cohort study consisted ACL-injured athletes were consecutively screened inclusion....
Background: There is no consensus regarding the best treatment approach for skeletally immature children with anterior cruciate ligament (ACL) injuries. High-quality studies long-term follow-up are lacking, and evidence to support decision making limited. Purpose: To evaluate functional patient-reported outcome, surgical history, complications among young adults who sustained an ACL injury before age of 13 years were treated active rehabilitation option delayed reconstruction if needed....
We like to think that we are successful in the treatment of individuals with anterior cruciate ligament (ACL) injury, but recent literature reveals only about 60% these make a full recovery, less than return sport, and more 50% develop knee osteoarthritis (OA) by middle age. Both short- long-term outcomes after ACL injury reconstruction need attention action. implement strategies early prevent development progression posttraumatic OA, rather "sit wait" until OA has developed. J Orthop Sports...
The objective of this study was to examine the association quadriceps strength symmetry and surgical status (anterior cruciate ligament [ACL] reconstruction or nonoperative management) with early clinical knee osteoarthritis (OA) 5 years after ACL injury reconstruction.In total, 204 300 athletes were analyzed reconstruction. Quadriceps measured reported as a limb index. We identified participants OA using criteria that 2 4 Knee Injury Osteoarthritis Outcome Score (KOOS) subscales score ≤85%....
