What Causes Pain in the Back of Your Knee?

Pain in the back of your knee typically stems from injury to muscles, tendons, or ligaments in the posterior knee region. The most common causes include Baker's cysts (fluid-filled sacs affecting up to 20% of adults), hamstring strains, and popliteal muscle injuries. Arthritis, meniscus tears, and posterior cruciate ligament damage can also trigger pain behind the knee. Other potential culprits include blood clots in the popliteal vein, nerve compression, or overuse injuries from repetitive activities like running or cycling. The location and type of pain often provide clues about the underlying cause, with sharp pain suggesting acute injury and dull aches indicating chronic conditions.
