BACKGROUND: The 2 most common definitive surgical interventions currently performed for the treatment of medial osteoarthritis of the knee are medial opening wedge high tibial osteotomy (HTO) and medial unicompartmental knee arthroplasty (UKA). Research exists to suggest that physically active patients may be suitably indicated for either procedure despite HTO being historically indicated in active patients and UKA being more appropriate for sedentary individuals. PURPOSE: To help consolidate the current indications for both procedures regarding physical activity and to ensure that they are based on the best information presently available...

BACKGROUND: The short-term outcomes of anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone or hamstring tendon (HT) graft are excellent with good clinical stability and patient-reported outcomes. Although some studies have reported the long-term outcomes of bone-patellar tendon-bone graft ACL reconstruction, few have reported the outcomes of HT graft ACL reconstruction. PURPOSE: To assess clinical and radiographic outcomes of HT graft ACL reconstruction with femoral cortical button fixation at a minimum 20-year follow-up...

BACKGROUND: Although joint-line obliquity (JLO) after open-wedge high tibial osteotomy (OWHTO) is commonly encountered, especially in cases of overcorrection, its effect has not been fully elucidated or has been assessed only in the short term. The acceptable range of JLO, often recognized as ≤4°, has not been determined as per the midterm outcomes of OWHTO. HYPOTHESIS: Joint-line obliquity exceeding the acceptable limit after OWHTO would accelerate cartilage degeneration and adversely affect midterm clinical outcomes...

BACKGROUND: Current regulations surrounding the use of osteochondral allografts (OCAs) in the United States require delayed graft release after 14 days to complete infectious disease screening. With a generally accepted expiration time of 28 days in storage, a limited window from 14 to 28 days remains for implantation. Yet, the rates of graft survival and thus optimal time for transplantation within this window remain largely unknown. HYPOTHESIS: OCAs transplanted within 19 to 24 days would have lower failure rates at 5 years than those transplanted at 25 to 27 days...

BACKGROUND: Osteochondral autograft transplant (OAT), a surgical treatment for capitellar osteochondritis dissecans (OCD), has favorable rates of elbow recovery and return to sports in adolescents. However, few reports have investigated how long patients continue to play baseball after OAT and their satisfaction with their treatment outcome. PURPOSE: To evaluate the rate of boys who played baseball and received OAT for OCD in junior high school or earlier (age <15 years) and continued to play baseball in high school and the players' satisfaction with their elbow function during play...

BACKGROUND: Patients experience varying degrees of pain and symptoms during the early recovery period after hip arthroscopy for femoroacetabular impingement (FAI). Some "fast starters" report minimal discomfort and are eager to advance activities, while "slow starters" describe severe pain and limitations. The relationship between these early postoperative symptoms and 2-year outcomes after hip arthroscopy is unknown. PURPOSE: To analyze the relationship between early postoperative pain and 2-year patient-reported outcomes (PROs) after hip arthroscopy for FAI...

BACKGROUND: Complete arthroscopic repair can treat small to large rotator cuff tears (RCTs) with good outcomes; however, the repair might be compromised by inflammation. PURPOSE: To investigate the prognostic value of preoperative lymphocyte to monocyte ratio (LMR), a marker of systemic inflammation before surgery, in arthroscopic rotator cuff repair. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Between January 2014 and January 2016, primary small to large RCTs without stiffness, significant muscle fatty infiltration, or atrophy were completely repaired in 110 consecutive patients and followed...

BACKGROUND: Symptom assessment is a critical component of concussion diagnosis and management, with item selection primarily driven by clinical judgment or expert consensus. We recently demonstrated that concussion symptoms assessed by the Sport Concussion Assessment Tool (SCAT) are essentially unidimensional, implying that overall symptom severity may be accurately estimated with relatively few questions. Briefer, evidence-based forms for symptom assessment would provide clinicians flexibility...

BACKGROUND: Inconsistent associations have been reported for impact-related ground reaction force variables and running injuries when grouping all injuries together. However, previous work has shown more consistent associations when focusing on specific injuries. PURPOSE: To compare ground reaction force variables between healthy and injured runners as a group and within specific common injuries. STUDY DESIGN: Controlled laboratory study. METHODS: A total of 125 runners presenting with patellofemoral pain, tibial bone stress injury, plantar fasciitis, Achilles tendinopathy, or iliotibial band syndrome and 65 healthy controls completed an instrumented treadmill assessment at a self-selected speed...
