Verified step by step guidance

Step 1: Understand the anatomy of the joints listed in the problem. The knee joint, hip joint, elbow joint, and shoulder joint are all synovial joints, which allow for a wide range of motion and are commonly involved in physical activities.

Step 2: Consider the biomechanics of each joint. The knee joint, for example, bears a significant amount of weight and is involved in activities like running, jumping, and pivoting, making it prone to injuries such as ligament tears (e.g., ACL injuries).

Step 3: Evaluate the susceptibility of each joint to sports injuries based on its structure and function. The shoulder joint, being highly mobile, is prone to dislocations and rotator cuff injuries. The hip joint, while strong, is less commonly injured in sports. The elbow joint is susceptible to overuse injuries like tennis elbow but less so to acute trauma.

Step 4: Compare the frequency and types of injuries associated with each joint in sports. Research and clinical data often indicate that the knee joint is the most commonly injured joint in sports due to its complex structure and the forces it endures during athletic activities.

Step 5: Conclude that the knee joint is the most susceptible to sports injuries based on its anatomical vulnerability, the types of forces it experiences, and the prevalence of injuries reported in sports medicine studies.
