Lower ACLR Failure Rates in Bone-Soft Tissue Versus Soft Tissue-Only Allografts in Adults: A Systematic Review and Meta-analysis.

Background: While allografts are commonly used for anterior cruciate ligament reconstruction (ACLR), evidence to guide specific allograft selection is lacking.

Purpose: To compare clinical and graft failure rates after ACLR using soft tissue-only allografts and bone-soft tissue allografts in adults.

Study Design: Systematic review and meta-analysis; Level of evidence, 4.

Synthetic medial meniscus implant demonstrates high reoperation rates: Patients who retain implant or require implant exchange show improvement in post meniscectomy knee pain and clinical function.

Purpose: To evaluate the clinical outcomes in the use of a synthetic medial meniscus implant in patients symptomatic after medial meniscectomy and not responsive to nonoperative treatment.

Methods: This single-arm, multicenter, prospective study enrolled subjects between ages 30 and 75 with postmeniscectomy pain. Changes from baseline to 24 months were measured in the pain subscale of the knee injury and osteoarthritis outcome score (KOOS) and in KOOS overall (average of all 5 subscales) in patients that had received a medial meniscus implant.

Association Between Longitudinal Changes in Patellar Tendon Abnormality and Land-Jump Biomechanics in Male Collegiate Basketball Players.

Background: The relationship between self-reported symptoms and the severity of patellar tendon abnormality (PTA) as seen on magnetic resonance imaging and ultrasound is unclear, but biomechanical testing may resolve this.

Purpose: To (1) compare land-jump limb biomechanics between pre- and postseason timepoints, (2) assess whether seasonal changes in biomechanics are associated with seasonal changes in PTA and symptom severity, and (3) explore models that identify seasonal changes in PTA and symptoms with seasonal changes in biomechanics in collegiate basketball players.

Study Design: Cohort study; Level of evidence, 2.

Impact of Joint Laxity on 2-Year KOOS Outcomes of Posterior Stabilized Total Knee Arthroplasty.

The objective of this study was to determine relationships between intraoperative posterior cruciate ligament (PCL) sacrificing posterior stabilized (PS) total knee arthroplasty (TKA) laxity measurements throughout flexion and patient outcomes at 2 years post-TKA and to define clinically relevant laxity thresholds to optimize patient outcomes.In a single-surgeon study, PCL sacrificing TKA using a robotics-assisted platform with a digital joint tensioning device was performed in 115 knees in 115 patients. Final intraoperative joint laxity was recorded, and 2-year Knee Injury and Osteoarthritis Outcome Scores (KOOSs) were obtained.

Clinical study of a micro-implantable pulse generator for the treatment of peripheral neuropathic pain: 3-month and 6-month results from the COMFORT-randomised controlled trial.

Background: We report the results from the first large, postmarket, multicentre, randomised controlled trial (RCT) evaluating peripheral nerve stimulation (PNS) for the treatment of chronic peripheral pain with a micro-implantable pulse generator (micro-IPG).

Methods: Subjects meeting eligibility were randomised (2:1) to either the active arm receiving PNS and conventional medical management (CMM) or the control arm receiving CMM alone. Treatments were limited to the following areas: lower back, shoulder, knee and foot/ankle.

Association Between Patellar Tendon Abnormality and Land-Jump Biomechanics in Male Collegiate Basketball Players During the Preseason.

Background: Patellar tendinopathy is a degenerative condition that predominantly affects jumping athletes. Symptoms may be subtle or nonexistent at preseason, but structural abnormalities may be present. Assessing patellar tendon abnormality (PTA) through magnetic resonance imaging (MRI) and ultrasound (US) and classifying symptoms using the Victorian Institute for Sport Assessment-Patellar tendon (VISA-P) may provide useful insights if combined with biomechanics measurements.

Bicycling over a Lifetime Is Associated with Less Symptomatic Knee Osteoarthritis: Data from the Osteoarthritis Initiative.

Introduction: This study aimed to evaluate the relationship between a history of bicycling and symptomatic and structural outcomes of knee osteoarthritis (OA), the most common form of arthritis.

Methods: This was a retrospective, cross-sectional study within the Osteoarthritis Initiative (OAI), where we investigated OAI participants with complete data on bicycling, knee pain, and radiographic evidence of knee OA. We used a self-administered questionnaire at the 96-month OAI visit to identify participation in bicycling during four time periods throughout a participant's lifetime (ages 12-18, 19-34, 35-49, and >50 yr).

Anterolateral Ligament and Kaplan Fiber Injury Both Occur Frequently in Acute Anterior Cruciate Ligament-Injured Knees.

Background And Objectives: The association of ALL and KF injuries in anterior cruciate ligament (ACL)-deficient knees remain topics of conflicting research despite improved magnetic resonance imaging (MRI). We aimed to evaluate the rate of the anterolateral ligament (ALL) and Kaplan fibers (KF) injuries in adults with acute ACL injuries using MRI.

Methods: We retrospectively reviewed 64 patients with clinical and MRI diagnoses of acute ACL tears.

The Influence of Tibial Tubercle-Sparing Slope-Reducing Osteotomy on Patellar Height in Patients Undergoing Revision ACL Reconstruction.

Background: A posterior tibial slope (PTS) >12° is an independent risk factor for anterior cruciate ligament (ACL) graft rupture, and a high tibial osteotomy (HTO) for slope correction can help avoid it. Management of patellar height is of major concern when performing HTO.

Purpose: To evaluate the effect of tibial tubercle-sparing anterior closing-wedge osteotomy on patellar height in revision ACL reconstruction (ACLR).

Experts Achieve Consensus on a Majority of Statements Regarding Platelet-Rich Plasma Treatments for Treatment of Musculoskeletal Pathology.

Purpose: To establish consensus statements on platelet-rich plasma (PRP) for the treatment of musculoskeletal pathologies.

Methods: A consensus process on the treatment of PRP using a modified Delphi technique was conducted. Thirty-five orthopaedic surgeons and sports medicine physicians participated in these consensus statements on PRP.

Evidence Review for Preventing Osteoarthritis After an Anterior Cruciate Ligament Injury: An Osteoarthritis Action Alliance Consensus Statement.

Context: The Osteoarthritis Action Alliance formed a secondary prevention task group to develop a consensus on secondary prevention recommendations to reduce the risk of osteoarthritis after a knee injury.

Objective: Our goal was to provide clinicians with secondary prevention recommendations that are intended to reduce the risk of osteoarthritis after a person has sustained an anterior cruciate ligament injury. Specifically, this manuscript describes our methods, literature reviews, and dissenting opinions to elaborate on the rationale for our recommendations and to identify critical gaps.

Preventing Osteoarthritis After an Anterior Cruciate Ligament Injury: An Osteoarthritis Action Alliance Consensus Statement.

After an anterior cruciate ligament (ACL) injury, people need secondary prevention strategies to identify osteoarthritis at its earliest stages so that interventions can be implemented to halt or slow the progression toward its long-term burden. The Osteoarthritis Action Alliance formed an interdisciplinary Secondary Prevention Task Group to develop a consensus on recommendations to provide clinicians with secondary prevention strategies that are intended to reduce the risk of osteoarthritis after a person has an ACL injury. The group achieved consensus on 15 out of 16 recommendations that address patient education, exercise and rehabilitation, psychological skills training, graded-exposure therapy, cognitive-behavioral counseling (lacked consensus), outcomes to monitor, secondary injury prevention, system-level social support, leveraging technology, and coordinated care models.

Medial-Sided Ligamentous Injuries of the Athlete's Knee: Evaluation and Management.

The superficial medial collateral ligament (sMCL) is the most commonly injured ligamentous structure in the knee. The other medial knee stabilizers include the deep medial collateral ligament, the posterior oblique ligament, and the medial meniscus. Medial collateral ligament injuries frequently occur in young athletes.

All-Soft Tissue Quadriceps Tendon Autograft in Revision Anterior Cruciate Ligament Reconstruction in Athletes: Comparison to Bone-Patellar Tendon-Bone Autograft With at Least a 2-Year Follow-up.

Background: Revision anterior cruciate ligament (ACL) reconstruction is being performed at an increasing rate. Previous literature has suggested that autograft ACL reconstruction is a better option than allograft in revision surgery, although the optimal autograft choice remains unknown. The all-soft tissue quadriceps tendon (ASTQT) autograft has been found to be an effective option for primary ACL reconstruction.

Determinants of Biomechanical Efficiency in Collegiate and Professional Baseball Pitchers.

Background: Biomechanical efficiency, defined as fastball velocity per unit of normalized elbow varus torque, is a relatively new metric applied to improving the performance and health of baseball pitching.

Purpose/hypothesis: The purpose of this work was to evaluate kinematic parameters influencing biomechanical efficiency among professional and collegiate pitchers. Kinematic differences were compared between pitchers of high and low biomechanical efficiency.

Pediatric hurdle-related acute injuries in track and field presenting to US emergency departments: descriptive epidemiology study.

Background: Hurdling is a track event that is unique due to a combination of running and jumping over an apparatus. Since hurdling requires a special skillset with sprinting and jumping, athletes are at risk for various musculoskeletal injuries. However, there has been a paucity of studies describing the epidemiology of pediatric hurdle injuries.

Partial Superior Capsular Reconstruction to Augment Arthroscopic Repair of Massive Rotator Cuff Tears Using Autogenous Biceps Tendon: Effect on Retear Rate.

Background: Massive rotator cuff tears have a high incidence of postoperative retear that can reach 90%. It is still unclear which intervention may reduce the incidence of retear and improve the functional and clinical outcomes.

Purpose/hypothesis: The purpose of this study was to investigate the clinical and structural outcomes at 2 years after repair of reparable massive rotator cuff tears with and without the use of partial superior capsular reconstruction (pSCR), using the autologous long head of the biceps tendon (LHBT) as a graft.

Bilateral Comparison of Anterior Shoulder Position in Elite Tennis Players.

Background: In elite tennis players, musculoskeletal adaptations in the dominant upper extremity have been reported for range of motion, strength, and scapular biomechanics. In addition to scapular dysfunction, tightness and inflexibility of the pectoral musculature have been identified as risk factors for the development of overuse shoulder injury in overhead athletes.

Hypothesis: Differences in anterior shoulder position will be identified between the dominant and non-dominant extremity in elite tennis players.
