Dr. Musahl’s research interests include knee and shoulder biomechanics. Dr. Musahl and Richard Debski, PhD, Associate Professor of Bioengineering and Orthopaedic Surgery, work together in the Orthopaedic Robotics Labortory (ORL) in Pittsburgh, and are examining older individuals with rotator cuff tears. They are examining the size and location of the tear with the goal of helping surgeons to determine what forms and combinations of treatment — injections, physical therapy, or surgery — are most effective. They also are building computational models that forecast various scenarios by varying the properties of thetear and surrounding tissue. Another research project focused on the impact of exercise therapy on torn rotator cuffs. Patients underwent 12 weeks of exercise therapy: six weeks with a physical therapist, and six weeks of a home-based program that focused on restoring range of motion and strengthening the rotator cuff and scapular muscles. Patients had x-rays taken before and after physical therapy to assess improvements in shoulder movement. The results of this study will be presented at the Orthopaedic Research Society 2015 Annual Meeting.The results of the research conducted in the ORL are moving the needle on the availability of evidence-based decision-making tools for surgeons regarding the treatment of rotator cuff tears. Future ORL research will focus on tear chronicity to determine how the age of a tear affects how it propagates and impacts surrounding tissue.

1. STABILITY 2: ACL Reconstruction +/- Lateral Tenodesis with Patellar vs. Quad Tendon
National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIH)
U01AR07614401, 09/01/2021- 08-31-2022, $648,412
This study has the general aim of identifying the optimal surgical management of ACL injury: Specific aims within this general aim are: 2) Determine if graft type quadriceps, patellar, or hamstring tendon autograft (QT, BPTB, HT, respectively) with or without a lateral extra-articular tenodesis (LET) affects the rate of ACL clinical failure 2 years after ACL reconstruction. 2) Determine if graft type (QT, BPTB or HT) with or without a LET affects patient-reported symptoms, function & quality of life, performance-based measures of function and return-to-sports 2 years after ACL reconstruction. 3) To determine if graft type (QT, BPTB or HT) with or without LET affects rates of intervention-related donor site morbidity, complications and adverse outcomes 2 years after ACL reconstruction. 4) Determine if use of a particular graft type (QT, BPTB or HT) with or without a LET is a more cost-effective approach to ACL reconstruction. To achieve these aims, an international 21-site multicenter randomized trial is being conducted that includes 1236 participants undergoing ACL reconstruction who are skeletally mature, participate in pivoting sports at high risk for graft failure. Participants are randomized to graft type (bone patellar tendon bone [BPTB] or quadriceps tendon [QT] autograft) with or without a lateral extra-articular tenodesis (LET). Outcome measures include ACL clinical failure, patient-reported outcomes, performance-based measures of function, return to pre-injury sports, adverse outcomes, intervention-related donor site morbidity and complications.
2. Timing and Rehabilitation (STaR) of Multiple Ligament Knee Injuries (MLKI)s: A Multicenter Integrated Clinical Trial
Department of Defense (USAMRAA)
W81XWH-17-2-0073, 9/30/2017 – 9/29/2021, $2,962,738
The overall purpose of this project is to determine when it is best to do surgery (within 6 weeks of injury or 3 to 4 months after injury) and when to start rehab (immediately or 4 weeks after surgery) for the treatment of knee dislocations on how long it takes to resume pre-injury military duty, work, and sports.
3. Predicting the Outcome of Exercise Therapy for Treatment of Rotator Cuff Tears (POETT)
National Institute of Health
NIH R01AR069503-01A1, 09/01/2016 – 5/31/2021, $2,021,020
