BACKGROUND: While there is extensive literature on the use of allograft versus autograft in anterior cruciate ligament (ACL) reconstruction, there is limited clinical evidence to guide the surgeon in choice of allograft tissue type. PURPOSE: To assess the revision rate after primary ACL reconstruction with allograft and to compare revision rates based on allograft tissue type and characteristics. STUDY DESIGN: Cohort study; Level of evidence, 3...

JOURNAL ARTICLE
Sierra N Murphy, Joseph C Brinkman, Sailesh V Tummala, Sean P Renfree, Kacey J Kemper, Kostas J Economopoulos
BACKGROUND: Meniscal root repair can improve patient outcomes significantly; however, several contraindications exist, including arthritic change to the medial or lateral tibiofemoral compartments. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate the outcomes of meniscal root repair in patients with advanced patellofemoral chondromalacia (PFC). It was hypothesized that the presence of advanced PFC would not significantly affect the postoperative outcomes...

JOURNAL ARTICLE
Caitlin C Chambers, John A Lynch, Brian T Feeley, Michael C Nevitt
BACKGROUND: Medial meniscus root tears (RTs) are associated with the development and worsening of knee osteoarthritis (OA), but little is known about their progression when compared with meniscal tears that spare the root (nonroot tears; NRTs). PURPOSE: To compare radiographic worsening of OA in knees with RTs versus NRTs and to identify factors associated with radiographic worsening of OA in knees with RTs. STUDY DESIGN: Cohort study; Level of evidence, 3...

BACKGROUND: In a previous study, the authors found that at 6 months after treatment with a 20 × 106 dose of bone marrow-derived mesenchymal stem cells (BM-MSCs), patients showed improved tendon structure and regeneration of the gap area when compared with treatment using leukocyte-poor platelet-rich plasma (Lp-PRP). The Lp-PRP group (n = 10), which had not seen tendon regeneration at the 6-month follow-up, was subsequently offered treatment with BM-MSCs to see if structural changes would occur...

BACKGROUND: Engaging Hill-Sachs lesions (HSLs) pose a significant risk for failure of surgical repair of recurrent anterior shoulder instability. Reconstruction with fresh osteochondral allograft (OCA) has been proposed as a treatment for large HSLs. PURPOSE: To determine the optimal characteristics of talus OCA bone plugs in a computer-simulated HSL model. STUDY DESIGN: Descriptive laboratory study; Level of evidence, 6. METHODS: Included were 132 patients with recurrent anterior instability with visible HSLs; patients who had multidirectional instability or previous shoulder surgery were excluded...

JOURNAL ARTICLE
Jade Perry, Jan Herman Kuiper, Helen S McCarthy, Paul Jermin, Peter D Gallacher, Bernhard Tins, Sally Roberts
BACKGROUND: Treatment decisions for cartilage defects are often based on lesion size. Magnetic resonance imaging (MRI) is widely used to diagnose cartilage defects noninvasively; however, their size estimated from MRI may differ from defect sizes measured during arthrotomy, especially after debridement to healthy cartilage if undergoing autologous chondrocyte implantation. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate the reliability of 2 methods to assess knee cartilage defect size on preoperative MRI and determine their accuracy in predicting postdebridement defect sizes recorded during arthrotomy...

BACKGROUND: Ulnar collateral ligament (UCL) injuries occur frequently in baseball players, and UCL reconstruction is performed when nonoperative treatment fails. PURPOSE: To compare a novel all-suture anchor method of UCL reconstruction with a method using bone tunnels (Ito method) by investigating the displacement against valgus torque and the failure strength.

BACKGROUND: Return-to-sports (RTS) rates after anterior cruciate ligament (ACL) reconstruction (ACLR) differ according to the level at which patients return. It is unclear whether the level of RTS is affected by psychological readiness to return. PURPOSE: To examine the association between psychological readiness to RTS and subjective RTS level 12 months after ACLR. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: A total of 47 patients who underwent unilateral primary ACLR surgery were enrolled...

BACKGROUND: Poor postoperative quadriceps muscle strength recovery after anterior cruciate ligament reconstruction (ACLR) leads to delayed return to sports and lower patient satisfaction. PURPOSE/HYPOTHESIS: The purpose of this study was to examine factors that affect quadriceps muscle strength 1 year after ACLR. It was hypothesized that older age, poor preoperative quadriceps muscle strength, and residual pain would be risk factors for poor quadriceps muscle strength recovery...

BACKGROUND: There are no definitive anatomic morphometric risk factors for adolescent anterior cruciate ligament (ACL) injury. PURPOSE: To compare the parameters used to define the tibial and femoral morphometric structure of the knee between adolescent patients with and without ACL rupture. STUDY DESIGN: Cross-sectional study; Level of evidence, 3.

BACKGROUND: For anterolateral rotatory instability as a result of secondary soft tissue injuries in anterior cruciate ligament (ACL)-deficient knees, there is increasing interest in secondary stabilizers to prevent internal rotation (IR) of the tibia. PURPOSE: To determine which secondary stabilizer is more important in anterolateral rotatory instability in ACL-deficient knees. STUDY DESIGN: Controlled laboratory study. METHODS: The lower extremities of 10 fresh-frozen cadavers (20 extremities) without anterior-posterior or rotational instability were included...

BACKGROUND: Posterolateral corner (PLC) knee injuries associated with different injury mechanisms are not well known. PURPOSE/HYPOTHESIS: This study sought to assess the patterns of associated injuries in the setting of PLC injury. The hypothesis was that there are recognizable injury patterns in PLC injuries that may correlate with injury mechanism. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Patients who sustained a multiligament knee injury were retrospectively reviewed...

BACKGROUND: The impact of interlimb asymmetries on sport injuries is unclear because of inconsistent findings, and there is a lack of research on youth athletes and the sport of taekwondo. PURPOSE: To examine the effects of functional interlimb asymmetries on noncontact lower limb injuries in youth athletes. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A total of 415 taekwondo athletes (318 boys and 97 girls) aged 6 to 17 years underwent baseline testing to determine interlimb asymmetries through the single-leg countermovement jump (CMJ), hop, and triple hop tests as well as the Star Excursion Balance Test...

BACKGROUND: Internal impingement is a common cause of shoulder pain and dysfunction in baseball pitchers. PURPOSE/HYPOTHESIS: The purpose of this study was to determine if the amount of rest days between outings, the number of innings pitched in each outing, and the number of batters faced in each outing are risk factors for internal impingement in professional baseball pitchers. It was hypothesized that a higher workload would significantly increase a pitcher's risk of developing internal impingement...
