Which type of exercise is likely inappropriate for someone prior to knee surgery?

A high-intensity plyometric program is likely inappropriate for someone prior to knee surgery because these exercises involve explosive movements that place substantial stress on the knee joint. Plyometric exercises can exacerbate existing conditions, lead to increased pain, or cause further injury due to the demand they place on the ligaments, tendons, and muscles around the knee. Prior to surgery, individuals should focus on low-impact, controlled movements that maintain joint stability and prevent deterioration of function without adding undue stress.

In contrast, low-intensity mobility exercises, gentle stretching exercises, and isometric strength exercises are often considered safe and appropriate. These options promote range of motion, flexibility, and muscle activation without risking additional strain on a compromised knee.
