The primary objective of this study is to assess the relationship between strength, range of motion, and neuromuscular control in the overhead throwing athlete.

• Criteria for inclusion of study subjects:
  • Baseball or softball athlete between 8-25 years old
  • Diagnosed with any non-traumatic elbow or shoulder injury determined to be caused from throwing and are undergoing conservative or surgical treatment for that injury
  • Complaints of elbow and/or shoulder pain that has limited and/or restricted participation in baseball or softball
  • Attempting to return to baseball or softball at a competitive level (little league, middle school, high school, select, collegiate or professional)
• Healthy controls who fit the following criteria:
  • Baseball or softball athlete between 8-25 years old
  • Have not undergone elbow or shoulder surgery in the past
  • No current complaints of elbow or shoulder pain that has limited and/or restricted participation in baseball or softball

The primary objective of this study is to investigate pre-operative measures in athletes whom sustained an injury to the anterior cruciate ligament (ACL) and to compare with post-operative outcomes.

• Criteria for inclusion of study subjects:
  • ACL injury for the first or second time on the involved limb
  • Between 13 and 25 years of age
  • Involved in a level 1 sport (e.g., basketball, football, or soccer) or level 2 sport (e.g., baseball, racket sports, or skiing). Sport must include activities such as jumping, pivoting, or hard cutting.
  • Participate in a physical therapy return-to-sport rehabilitation program
  • Do not have a full thickness chondral defect of 1cm 2 or greater
  • Do not have a Grade II or III MCL or LCL sprain, posterior cruciate ligament tear (grade III), simultaneous fracture with ACL tear

The primary objective of this study is to investigate pre-operative measures in athletes whom have had an anterior cruciate ligament (ACL) repair or reconstruction and to compare with post-operative outcomes.

• Criteria for inclusion of study subjects:
  • Between 12-60 years old
  • Recreational or competitive athlete participating in at least 50 hours/year
  • Participate in a physical therapy return-to-sport rehabilitation program
  • Do not have a full thickness chondral defect of 1cm 2 or greater
  • Do not have a Grade II or III MCL or LCL sprain, posterior cruciate ligament tear (grade III), or simultaneous fracture with ACL tear

The primary objective of this study is to determine normative values of lower extremity training loads from immediate post-surgery to return to sport for patients who have undergone ACL reconstruction.

• Criteria for inclusion of study subjects:
  • Between 13-25 years old
  • Injured their ACL for the first time
  • Involved in a level 1 sport (e.g., basketball, football, or soccer) or level 2 sport (e.g., baseball, racket sports, or skiing). Sport must include activities such as jumping, pivoting, or hard cutting.
  • Participate in a physical therapy return-to-sport rehabilitation program
  • Do not have a full thickness chondral defect of 1cm 2 or greater

The primary objective of this study is to investigate risk factors for injuries of the lower extremity in competitive athletes. The secondary objective of this study is to develop a risk stratification model for lower extremity injuries in the competitive athlete.

• Criteria for inclusion of study subjects:
  • Between 10-25 years old
  • Involved in a level 1 sport (e.g., basketball, football, or soccer) or level 2 sport (e.g., baseball, racket sports, or skiing). Sport must include activities such as jumping, pivoting, or hard cutting
  • If they are not experiencing an active lower extremity orthopedic injury (having been injured within the last 3 months)

The primary objective of this study is to examine the hip and groin in adolescent athletes by classifying injury into specific clinical pathways, assessing functional biomarkers related to performance, and prospectively tracking athletes for onset of hip and groin symptoms and retesting of the functional biomarkers.

• Criteria for inclusion of study subjects:
  • Soccer athlete currently participating at any competitive level
  • Between 10-40 years old
  • Not currently experiencing a lower extremity orthopedic injury that prevents them from completing study procedures

The primary objective of this study is to evaluate clinical and surgical outcomes from orthopedic care delivered in the outpatient setting for analysis and reporting of patient-derived value.

• Criteria for inclusion of study subjects:
  • Males and females aged 12-75.
  • Individuals diagnosed and treated for non-arthritic hip pain.
  • Individuals diagnosed and treated for extra-articular pathologies related to the hip.

The primary purpose of this study is to assess outcomes and cost-effectiveness following orthopedic surgery. The secondary objective is to compare surgical outcomes to outcomes of non-operative treatment procedures

• Criteria for inclusion of study subjects:
  • Between 12-100 years old
  • Present to the clinic and elect to schedule routine and medically indicated orthopedic surgery or a non-operative treatment option by a participating physician

The primary objective of this study is to evaluate clinical and surgical outcomes from sports medicine and orthopedic care delivered in the outpatient setting for analysis and reporting of patient-derived value.

• Criteria for inclusion of study subjects:
  • Males and females aged 5 – 100.
  • Individuals diagnosed and treated for sports medicine and orthopedic injuries.
  • Must be able to read and understand English and consent for themselves
