As part of its mission, ISAKOS supports orthopaedic research and education by funding the highest-quality international research proposals. The Scientific Committee oversees four ISAKOS research grants: (1) the New Researcher Grant, (2) the Osteoarthritis Grant, (3), the Clinical Outcomes Grant, and (4) the Countries with Limited Resources Grant. We are pleased to report on the outstanding progress made by the recipients from 2017 to 2019.
New Researcher Grant
The New Researcher research grant was awarded to Dr. Trifon Totlis (TheMIS Orthopaedic Center, St. Luke’s Hospital, Thessaloniki, Greece) for “Validation of a Computer Tablet Software for Quantification of Scapular Motion During Clinical Assessment of Scapular Dyskinesia.” Scapular dyskinesia may dynamically reduce the subacromial space, leading to impingement. Currently, such abnormal scapular movement is qualitatively assessed by subjective visual observation1. Motion-tracking systems have been used to quantify this abnormal motion, but their availability is quite limited.
38 ISAKOS NEWSLETTER 2019: VOLUME II
Image analysis of the skin motion around the knee joint has been developed to capture the pivot-shift phenomenon2, and the image-analysis methodology was installed as an application on a computer tablet (iPad)3. The hypothesis of the study is that this technology might be utilized to evaluate scapular motion as it relates to dyskinesia. Thus, this new research aims to establish an objective and easily applicable method to quantify the scapular motion in patients with scapular dyskinesia. Twenty-five patients with symptomatic unilateral scapular dyskinesia and 19 healthy controls were tested. The scapular movement during arm-lowering was captured with the iPad (Fig. 1). The deviation of the inferior angle from the thoracic wall was calculated with the installed software. This measurement was significantly higher in the dyskinetic scapulae as compared with both the contralateral non-dyskinetic scapulae and normal healthy controls. The data were presented at the 2019 ISAKOS meeting in Cancun, and the manuscript has been submitted to the ISAKOS journal.

Osteoarthritis Grant
The Osteoarthritis research grant was awarded to Dr. Tiago Fernandes (Department of Orthopaedics and Traumatology, University of São Paulo Medical School and Sírio-Libanês Hospital, São Paulo, Brazil) for his proposal on the “Comparison of Tissue-Engineered-Construct (TEC)- Derived of Human Stem Cells From Dental Pulp and Synovia on Articular Cartilage Regeneration.” There are numerous treatment options for the treatment of cartilage lesions, but none of them provides complete healing with preinjury hyaline-like structure and function. Mesenchymal stem cell (MSC)-based therapy has the potential to enhance the healing of the damaged cartilage. Dental pulp has been reported to be a useful source of MSCs, but it has not been used for joint cartilage regeneration. On the other hand, the knee fat pad and synovia have been established as a potential source of MSCs.
