Factors affecting joint mobility include osteophytes, meniscal damage, glenoid labral damage, articular cartilage damage, etc. The details are as follows: 1. Osteophytes: osteophytes inside the joint and osteophytes at the edges can affect joint mobility, narrowing the range of motion of the joint and causing joint pain, swelling and deformation. 2. Meniscal damage, articular glenoid labral damage, articular cartilage damage, synovial hyperplasia and joint capsule contracture: all can cause changes in joint mobility, narrowing the range of motion of the joint and also affecting joint stability. Injury, articular cartilage injury, synovial hyperplasia, joint capsule contracture: all can cause changes in joint mobility, resulting in a severe narrowing of the joint range of motion, and also affect the stability of the joint. Therefore, there are several factors that affect joint mobility. Early diagnosis and early treatment can restore joint mobility, and patients can ensure their daily life and work.
