BACKGROUND: Weighted gait increases internal knee extension moment impulses (KEMI) in the anterior cruciate ligament-reconstructed (ACLR) limb; however, limb differences persist. HYPOTHESES: (1) KEMI during normal gait will influence KEMI during weighted gait and (2) peak knee extension (PKE) torque and time to reach PKE torque will predict KEMI during gait tasks. STUDY DESIGN: Descriptive laboratory study. METHODS: Twenty-four women and 14 men completed 3 gait tasks (unweighted, vest, sled) and strength testing after discharge from rehabilitation and clearance to return to sports...

One of the ligaments most often damaged during sports - the anterior cruciate ligament (ACL) - has poor healing capacity. Upon damage, reconstructive surgery is performed to restore the mechanical stability of the knee and to reduce the inflammatory milieu otherwise present in the joint. A return to normal activities, however, takes between 9 and 12 months. Thus, strategies capable of improving ACL graft healing are needed. Embryonic development of tendon and ligament (T/L) is regulated by a crosstalk between different cell types...

BACKGROUND: Excellent outcomes have been reported for anterior cruciate ligament (ACL) reconstruction (ACLR) in professional athletes in a number of different sports. However, no study has directly compared these outcomes between sports. PURPOSE: To determine if differences in performance-based outcomes exist after ACLR between professional athletes of each sport. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: National Football League (NFL), National Basketball Association (NBA), National Hockey League (NHL), and Major League Baseball (MLB) athletes undergoing primary ACLR for an acute rupture were identified through an established protocol of injury reports and public archives...

OBJECTIVES: Meniscus tears are one of the most common knee injuries. Our goal is to investigate the failure rate for surgically repaired bucket-handle meniscus tears and compare clinical outcomes of repairs that failed versus those that did not, at a minimum 2-year follow-up interval. METHODS: 51 patients were identified in this retrospective cohort study who experienced bucket-handle meniscus tears that were isolated or with concomitant ACL injury. Inclusion criteria included age range from 13-55 years, confirmed bucket-handle meniscus tear by MRI and intraoperatively, and at least two-years of post-operative follow-up following index repair...

Anterior cruciate ligament tears are common and affect young individuals who participate in jumping and pivoting sports. After injury many individuals undergo ligament reconstruction (ACLR) but do not return to play, suffer recurrent injury and osteoarthritis. Outcome studies show that after ACLR, 81% of individuals return to sports, 65% return to their preinjury level and 55% return to competitive sports. Systematic reviews place the risk of ipsilateral retears at 5.8% and contralateral injuries at 11.8%, with recent reports of over 20% failure rate...

BACKGROUND: Although anterior cruciate ligament (ACL) reconstruction is generally regarded as a successful procedure, only 65% of patients return to their preinjury sport. While return-to-sport rates are likely higher in younger patients, there is a paucity of data that focus on the younger patient and their return-to-sport experience after ACL reconstruction. PURPOSE: To investigate a range of return-to-sport outcomes in younger athletes who had undergone ACL reconstruction surgery...

BACKGROUND: Return to play and patient satisfaction after anterior cruciate ligament reconstruction (ACLR) have been inconsistently studied. The purposes of this study were to (1) investigate rates and predictors of return to play after ACLR, (2) evaluate patient satisfaction after ACLR, and (3) analyze the relationship between return to play and satisfaction with the result of ACLR. METHODS: Eligible patients were active athletes included in an institutional ACL registry who had undergone ACLR and had been followed for a minimum of 2 years...

BACKGROUND: There are limited data regarding associated factors of return to sports activities at more than 5 years after anterior cruciate ligament (ACL) reconstruction. PURPOSE: To test interrelationships between patient characteristics, concomitant articular lesions, graft laxity, and maintenance of sports activities at 5 to 10 years after ACL reconstruction. It was hypothesized that at 5 to 10 years after the operation in young adult men, maintenance of greater activity level and better knee function would be associated with greater preinjury activity level, younger age at reconstruction, absence of concomitant articular lesions, and minimal graft laxity at follow-up...

BACKGROUND: Reinjury rates after anterior cruciate ligament reconstruction (ACLR) are highest among young athletes, who consequently suffer from low rates of return to play. Historically, quantitative measures have been used to determine readiness to return to sport; however, they do not assess modifiable risk factors related to the quality of movement. PURPOSE: To determine the effectiveness of a criteria-based rehabilitation progression and return-to-sport criteria on efficient return to activity and prevention of second injury in young athletes post-ACLR...

BACKGROUND: Posterior cruciate ligament (PCL) reconstructions are rarely performed compared with that for the anterior cruciate ligament (ACL). PURPOSE: To evaluate the clinical and functional outcome after isolated or multiligament PCL reconstruction. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients who underwent PCL reconstruction between 2002 and 2010 were included. Standardized follow-up was performed between 2012 and 2013 and consisted of subjective scores (Tegner activity score, Knee injury and Osteoarthritis Outcome Score [KOOS], and subjective International Knee Documentation Committee [IKDC] score) and objective measures, including knee laxity (KT-1000), extension strength, and overall IKDC score...

BACKGROUND: The safest and most effective technique for anterior cruciate ligament (ACL) reconstruction in skeletally immature patients is currently unknown. PURPOSE: To evaluate the functional and patient-reported outcomes of a specific all-epiphyseal ACL reconstruction technique in which the graft, bone tunnels, and fixation do not cross the knee growth plates. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Twenty-seven patients (23 boys, 4 girls; mean age, 11 years; range, 8-15 years) underwent an all-epiphyseal ACL reconstruction with a single femoral transverse epiphyseal tunnel and primarily split tibial epiphyseal tunnels...

Matthew J Jordan, Per Aagaard, Walter Herzog
The purpose of the present review was to: 1) provide an overview of the current understanding on the epidemiology, etiology, risk factors, and prevention methods for anterior cruciate ligament (ACL) injury in alpine ski racing; and 2) provide an overview of what is known pertaining to ACL reinjury and return to sport after ACL injury in alpine ski racing. Given that most of the scientific studies on ACL injuries in alpine ski racing have been descriptive, and that very few studies contributed higher level scientific evidence, a nonsystematic narrative review was employed...

The Multicenter Orthopaedic Outcomes Network (MOON) is an NIH-funded prospective, longitudinal cohort of over 3,500 patients who have undergone anterior cruciate ligament reconstruction (ACLR) by 14 sports medicine surgeons at 7 academic medical centers. Patient reported outcome questionnaires (PRO's) are completed at baseline and multiple timepoints after surgery, and a nested cohort of patients return for radiographs to assess the development of joint space changes. We review the risk factors for worse patient reported outcomes, the predictors of clinically significant symptoms of post-traumatic osteoarthritis (PTOA), and the factors associated with more radiographic joint space narrowing...

Study Design Prospective cohort. Background The high risk of second anterior cruciate ligament (ACL) injuries after return to sport highlights the importance of return-to-sport decision making. Objective return-to-sport criteria frequently use limb symmetry indexes (LSIs) to quantify quadriceps strength and hop scores. Whether using the uninvolved limb in LSIs is optimal is unknown. Objectives To evaluate the uninvolved limb as a reference standard for LSIs utilized in return-to-sport testing and its relationship with second ACL injury rates...

Small animal models are critical for studies of sports-related knee injury and disease such as posttraumatic osteoarthritis (PTOA) following anterior cruciate ligament (ACL) rupture. In such models, ACL damage can be achieved by surgical transection or, using a more recent innovation, by noninvasive biomechanical means. Whether these approaches differentially alter normal mechanics is unknown. Furthermore, while surgical reconstruction of ruptured ACL can greatly improve joint stability, its effect on PTOA development is also unclear...
