Research Projects

  1. Management and Outcomes of Clinical Scaphoid Fractures in Children


    Management of clinical scaphoid fractures at our institution was relatively uniform: nearly all patients were immobilized and less than 20% received advanced imaging. Our findings suggest a low but non-zero occult scaphoid fracture rate, discordance in radiologic interpretation, and lack of advanced imaging, providing an avenue for future prospective studies.

  2. Protocol for the systematic review of return‑to‑activity criteria in adolescent patients following an anterior cruciate ligament reconstruction


    Our objective is to systematically examine the literature and identify the criteria used when determining unrestricted RTA following an ACL reconstruction in an adolescent population.

  3. Effect of Osteochondroplasty on Time to Reoperation After Arthroscopic Management of Femoroacetabular Impingement: Analysis of a Randomized Controlled Trial


    This time-to-event analysis with a 27-month follow-up analysis compared the effect of (1) arthroscopic osteochondroplasty with or without labral repair versus (2) arthroscopic lavage with or without labral repair on the time to reoperation in adults aged 18 to 50 years with FAI.

  4. Reliability of a New Arthroscopic Discoid Lateral Meniscus Classification System: A Multicenter Video Analysis


    This new arthroscopic DLM classification system demonstrated moderate to substantial agreement in most diagnostic categories analyzed.

  5. Arthroscopy Association of Canada Position Statement on Intra-articular Injections for Hip Osteoarthritis.


    However, similar recommendations for injections for the treatment of hip OA are lacking.
