Introduction
The knee is the common term for the knee joint, which is formed by the lower end of the femur, the upper end of the tibia, and the patella. Generally speaking, stair-climbing exercises can affect the knee joint. Stair climbing requires frequent knee flexion, increasing pressure on the knee joint. Prolonged or high-frequency stair-climbing exercise may加重 the burden on the knee joint, leading to knee pain and injury.

The knee is the common term for the knee joint, which is formed by the lower end of the femur, the upper end of the tibia, and the patella. Generally speaking, stair climbing can affect the knee joint. The specific details are as follows:

Stair climbing involves frequent knee flexion movements, which increase pressure on the knee joint. Prolonged or high-frequency stair climbing may加重 the burden on the knee joint, leading to knee pain and injury. The patella is an important component of the knee joint. During stair climbing, repeated knee flexion may increase friction between the patella and femur, potentially causing cartilage wear in the patella, patellar dislocation, and other problems. In addition, stair climbing primarily relies on the strength of the quadriceps muscles. If the quadriceps are overly tight or overdeveloped while other muscle groups—such as the gluteal and hamstring muscles—are relatively weak, muscle imbalances may occur, reducing knee joint stability and increasing the risk of injury.

It is recommended that individuals perform stair climbing in moderation, use proper posture and technique, and carry out adequate warm-up exercises and muscle stretching to prevent knee joint injuries. If discomfort occurs, it is advisable to seek medical attention promptly and receive standardized treatment under a doctor's guidance, which can promote recovery.
