What might prevent me from putting pressure on a bent knee?

When you bend your knee, many structures work together like bones, cartilage, muscles, and ligaments. If you have an injury such as a torn ligament (like in an anterior cruciate ligament tear) or damage from arthritis, your knee may hurt or feel unstable. This pain and weakness can stop you from being able to put pressure on a bent knee. • Pain signals from the injured tissue may tell your brain to avoid using the knee. • Swelling can make the joint more rigid and sensitive to pressure. • Muscle weakness, sometimes seen with knee osteoarthritis, means your muscles can't support the knee well during movement. • A feeling of instability from ligament damage can make you unconsciously protect the knee by not using it fully. All these factors can contribute to difficulty when trying to bear weight on your bent knee.
