Summary
Hong Kong's growing fitness culture has led to an increase in knee injuries among gym-goers, with orthopedic specialists urging better prevention measures. Dr. Chan Yee-hang (陳爾亨), a specialist in orthopedics and traumatology, has highlighted the risks associated with high-intensity exercises such as squat jumps, box jumps, and lunges that place enormous torsional stress on the knee joints .
Key Points
- The anterior cruciate ligament (ACL) connects the femur and tibia, playing a critical role in maintaining knee stability during jumping, pivoting, and sudden stops
- ACL tears typically occur through non-contact twisting mechanisms, with basketball, football, skiing, CrossFit, and HIIT workouts identified as high-risk activities
- Meniscus tears commonly affect individuals engaged in heavy squatting and leg press exercises, overweight persons, and those with improper knee alignment during training
- Treatment decisions depend on injury severity and the patient's activity demands, with surgery being an option rather than a requirement for all cases
- Six prevention strategies include dynamic warm-ups lasting 10-15 minutes, hip and core strengthening exercises such as glute bridges and side planks, maintaining proper form throughout training, limiting weekly load increases to 5-10%, wearing supportive footwear, and allowing adequate recovery time between sessions
