Summary
Knee pain presents differently depending on the underlying condition. Key symptoms include swelling, reduced range of motion, instability, and pain with movement. Certain symptoms — such as locking or sudden severe pain — signal a more serious injury.
Types of Knee Pain Symptoms
The location and nature of knee pain helps identify its cause. Pain on the outer side of the knee is often IT band syndrome; pain below the kneecap points to patellar tendinitis; deep aching with stiffness suggests arthritis.
Mechanical vs Inflammatory Symptoms
Mechanical symptoms (clicking, locking, giving way) usually indicate structural damage such as a torn meniscus or ligament. Inflammatory symptoms (warmth, redness, swelling) suggest conditions like bursitis, gout, or rheumatoid arthritis.
