Osteoarthritis(OA) Study

Evidence-based Sports Medicine for the Promotion of Lifelong Health
 - 2015, September, Funded by Korea Research Foundation – Research Center Grant
 - 1,800,000/year, 2015~2021 years
 - Dr. Lee, Co-PI for 2nd sub project: Prevention of OA

Prevention of OA post ACL surgery

■ High ODD ratio of OA: ACL+meniscus tear

 ■ How long was the treatment?
 ■ What type of treatment were provided?
 ■ When dose the OA diagnosed post-op?
 ■ What kind of OA was it?
    ■ When will be the best timing to provide intervention?

Future Direction - Strategy
 ■ Retrospective Cohort Study
 ■ Collaboration with Yonsei Severance Hospital
 ■ Korea has only “1” insurance provider: National Insurance Foundation
 ■ Huge big-database for medical history
 ■ Most of ACL surgery and OA are covered by insurance
 ■ Able to follow-up 5, 10, 15, 20, 25, and 30 years post ACL-OP
 ■ Able to follow-up treatment post ACL-OP
 

Mechanism study
 ■ Modeling study using CT and fluoroscopic tech to analyze stress distribution at the knee joint during dynamic task.
 ■ EMG to analyze contribution of muscle to prevent increase of focal compression.

Mechanism & Risk Factors

■ Ankle study
   • New investigators grant, Korea Research Foundation, 3 years, 2014~2016, $90,000

■ Osteoarthritis
   • Research center grant, Korea Research Foundation, 3+3+3, 2015~2021, $1,800,000/year

■ Normative database study
   • 14 static alignments
   • Dynamic alignment during walking, jogging, and landing
   • Use for screening tool for lower extremity injuries

(1) Ankle Study

Introduction of ISS system developed

Injury surveillance system in Korea

■ Pilot test of three major sports at Yonsei University
 - Basketball
 - Ice hockey
 - Baseball

■ A total of 205 student athletes and over 28,200 A-E

■ Developed Web based ISS with the expanded version of IOC ISS

■ Add winter sports and Taekwondo in collaboration with Korea University Sports Federation

Injury surveillance system in Korea - Basketball

Injury surveillance system in Korea – Ice hockey

• Hold hockey stick during body checking -> Increase moment arm
• Modeling study to examine anterior translation of humeral head with different arm position (hockey stick)

Injury surveillance system in Korea - Baseball

■ Future Direction - Strategy
-  Expand to winter and Taekwondo study
-  Professional team sports
- Add sports specific and mechanism questionnaires
