Rothman Institute Faculty Papers

Background: Despite the importance of accurately detecting ulnar nerve subluxation in vulnerable athletes, few studies have compared the performance of physical examination and ultrasound in this population. Purpose/Hypothesis: The purpose of this study was to compare the diagnostic validity of physical examination versus ultrasound in detecting ulnar nerve subluxation at the cubital tunnel of the elbow in professional baseball pitchers. It was hypothesized that ultrasound would more sensitively detect ulnar nerve subluxation. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Physical and sonographic examinations for ulnar nerve subluxation were performed on 186 elbows of 95 consecutive male professional …

Does Prehabilitation Before Surgery Affect Return To Sport In Baseball Pitchers With Partial Ulnar Collateral Ligament Tears?, Kourtney Snigar, Ryan W. Paul, Joshua M. Spada, Usman Zareef, Anya Hall, Brandon J. Erickson, Michael G. Ciccotti, Stephen J. Thomas

Rothman Institute Faculty Papers

BACKGROUND: Purposeful rehabilitation before surgery (prehabilitation) has been researched and implemented in the treatment of anterior cruciate ligament tears. However, it is unclear whether prehabilitation would affect outcomes for baseball pitchers with partial ulnar collateral ligament (UCL) tears.

PURPOSE/HYPOTHESIS: The purpose of this study was to determine whether baseball pitchers with partial UCL tears who completed ≥4 weeks of prehabilitation (prehab group) have different return to play (RTP) outcomes than pitchers with 0 to 3 weeks of preoperative physical therapy (no prehab group). We hypothesized that pitchers in the prehab group would have similar RTP rates compared with pitchers in …

Return To Recreational Sports Participation Following Rotator Cuff Repair In Adults Over 40 Years Of Age: Outcomes And Return To Play Analysis, John Hayden Sonnier, Gregory Connors, Michael P. Campbell, Matthew Sabitsky, Ryan W. Paul, Hayden E. Sando, William D. Emper, Steven B. Cohen, Michael G. Ciccotti, Fotios P. Tjoumakaris, Kevin B. Freedman

Rothman Institute Faculty Papers

Background: Despite the high prevalence of rotator cuff (RTC) tears in older adults, there is limited literature evaluating the return to recreational sport after repair. The purpose of this study was (1) to assess the patient-reported outcomes and return to sport rates following rotator cuff repair in patients aged more than 40 years with minimum 2-year follow-up; (2) to compare baseline, preoperative and postoperative outcomes, and level of play following repair of self-reported athletes with nonathletes; and (3) to compare return to sport rates in overhead athletes compared to nonoverhead athletes. Methods: Patients undergoing arthroscopic rotator cuff repair between January …

Beach Chair Versus Lateral Decubitus Surgical Positioning For Arthroscopic Anterior Shoulder Stabilization: A Retrospective Comparison Of Clinical And Patient-Reported Outcomes, Ryan W Paul, Sydney Streicher, Alim Osman, Chuka Ukekwe, Usman Zareef, Kevin B Freedman, Brandon J Erickson, Sommer Hammoud, Meghan E Bishop

Rothman Institute Faculty Papers

Background: Surgical positioning can affect both perioperative and postoperative complication rates. It is unclear whether beach-chair versus lateral decubitus positioning affects outcomes in patients undergoing arthroscopic anterior shoulder stabilization surgery.

Purpose: The purpose of this study was to compare recurrent instability, complications, and patient-reported outcomes between patients who underwent arthroscopic anterior shoulder stabilization in the beach-chair versus the lateral decubitus positions. It was hypothesized that recurrent instability, complications, and patient-reported outcomes would not be affected by surgical positioning.

Study Design: Cohort study; Level of evidence, 3.

Methods: The authors reviewed the medical records of patients who underwent shoulder stabilization ( …

Long-Term Sports Participation And Satisfaction After Ucl Reconstruction In Amateur Baseball Players., Robert A Jack, Somnath Rao, Taylor D'Amore, Donald Willier Iii, Robert Gallivan, Steven B. Cohen, Christopher C Dodson, Michael G. Ciccotti

Rothman Institute Faculty Papers

Background: While the incidence of ulnar collateral ligament reconstruction (UCLR) has increased across all levels of play, few studies have investigated the long-term outcomes in nonprofessional athletes.

Purpose: To determine the rate of progression to higher levels of play, long-term patient-reported outcomes (PROs), and long-term patient satisfaction in nonprofessional baseball players after UCLR.

Study Design: Case series; Level of evidence, 4.

Methods: We evaluated UCLR patients who were nonprofessional baseball athletes aged(KJOC), the Timmerman-Andrews (T-A) Elbow score, the Mayo Elbow Performance Score (MEPS), and a custom return-to-play questionnaire.

Results: A total of 91 baseball players met the inclusion criteria, and …

Rehabilitation And Return-To-Play Criteria After Fresh Osteochondral Allograft Transplantation: A Systematic Review., Michael Stark, Somnath Rao, Brendan Gleason, Robert A. Jack, Bradford Tucker, Sommer Hammoud, Kevin B. Freedman

Rothman Institute Faculty Papers

Background: Fresh osteochondral allograft (OCA) is a treatment option that allows for the transfer of size-matched allograft cartilage and subchondral bone into articular defects of the knee. Although long-term studies show good functional improvement with OCA, there continues to be wide variability and a lack of consensus in terms of postoperative rehabilitation protocols and return to sport.

Purpose: To systematically review the literature and evaluate the reported rehabilitation protocols after OCA of the knee, including weightbearing and range of motion (ROM) restrictions as well as return-to-play criteria.

Study Design: Systematic review; Level of evidence, 4.

Methods: PubMed, EMBASE, Cumulative Index …

Sex And Age Comparisons In Neuromuscular And Biomechanical Characteristics Of The Knee In Young Athletes, Erin R Pletcher, Travis J Dekker, Scott M Lephart, Tim C Sell

Department of Exercise Science Faculty Papers

Background: The identification of risk factors for injury is a key step for musculoskeletal injury prevention in youth sports. Not identifying and correcting for injury risk factors may result in lost opportunity for athletic development. Physical maturation and sex affect these characteristics, which may indicate the need for both age and sex-based injury prevention programs.

Hypothesis/purpose: This study examined age and sex differences in knee strength, static balance, jump height, and lower extremity landing biomechanics in school- and high school-age athletes.

Study design: Cross-sectional.

Methods: Forty healthy school aged (10.8±0.8 yrs) and forty high school (16.8±0.8 yrs) athletes completed isokinetic …

Return To Sport And Athletic Function In An Active Population After Primary Arthroscopic Labral Reconstruction Of The Hip, David R. Maldonado, Sarah L. Chen, Mitchell J. Yelton, Philip J. Rosinsky, Rafael Walker-Santiago, Jacob Shapira, Ajay C. Lall, Benjamin G. Domb

Student Papers, Posters & Projects

Background: Labral reconstruction has been advocated as an alternative to debridement for the treatment of irreparable labral tears, showing favorable short-term results. However, literature is scarce regarding outcomes and return to sport in the nonelite athletic population.

Purpose: To report minimum 1-year clinical outcomes and the rate of return to sport in athletic patients who underwent primary hip arthroscopy with labral reconstruction in the setting of femoroacetabular impingement syndrome and irreparable labral tears.

Study Design: Case series; Level of evidence, 4.

Methods: Data were prospectively collected and retrospectively analyzed for patients who underwent an arthroscopic labral reconstruction between August 2012 …
