Knee pain: What to know

Knee pain is a common complaint that affects millions of people worldwide. It can be a bothersome condition that limits daily activities and reduces overall quality of life. There are various causes of knee pain, and one particular area of concern is pain at the back of the knee. Understanding the reasons behind this type of pain is crucial in order to provide appropriate treatment and relief.

Posterior Cruciate Ligament Injury

One possible reason for experiencing pain at the back of the knee is a posterior cruciate ligament (PCL) injury. The PCL is a ligament located deep within the knee joint that connects the thighbone to the shinbone. It plays a vital role in stabilizing the knee and preventing excessive backward movement of the shinbone. PCL injuries can occur due to direct blows to the front of the knee, such as during a car accident or sports activities. Symptoms of a PCL injury include pain at the back of the knee, swelling, instability, and difficulty walking or bearing weight on the affected leg.

Biceps Femoris Tendon

Another possible cause of pain at the back of the knee is biceps femoris tendinopathy. The biceps femoris is one of the muscles located at the back of the thigh, and its tendon travels down to attach behind the knee joint. Tendinopathy is a condition that occurs when the tendon becomes damaged or inflamed. This can happen due to overuse or repetitive movements such as running or jumping. Symptoms of biceps femoris tendinopathy include pain behind the knee, tenderness, swelling, and difficulty straightening the leg.

Popliteal Tendonitis

Popliteal tendonitis is another potential cause of pain at the back of the knee. The popliteal tendon is located at the back of the knee joint and helps to stabilize the knee during movement. Tendonitis occurs when the tendon becomes inflamed and irritated. This can be caused by overuse, repetitive activities, or sudden, forceful movements. Common symptoms of popliteal tendonitis include pain at the back of the knee, tenderness, swelling, and difficulty bending or straightening the leg.

Referred Pain

Sometimes, pain at the back of the knee may not originate from the knee joint itself, but rather from a condition known as sciatica. Sciatica is a condition that occurs when the sciatic nerve, which runs from the lower back down the back of each leg, becomes compressed or irritated. This compression can cause pain to radiate down the leg, including the back of the knee. Other symptoms of sciatica include lower back pain, numbness or tingling in the leg or foot, and weakness in the affected leg.

Arthritis

Arthritis is a common condition that can affect any joint in the body, including the knee joint. Osteoarthritis, the most common form of arthritis, occurs when the protective cartilage that cushions the ends of the bones wears down over time, leading to pain, swelling, and stiffness. Arthritis in the knee can cause pain in various areas, including the back of the knee. This pain may be accompanied by limited range of motion, difficulty walking, and joint instability.

Gastrocnemius Tendinopathy

Gastrocnemius tendinopathy is a condition that involves inflammation or degeneration of the gastrocnemius tendon, which connects the calf muscles to the back of the knee. This condition can result from overuse or repetitive activities, such as running or jumping. Symptoms of gastrocnemius tendinopathy include pain at the back of the knee, swelling, tenderness, and difficulty walking or bearing weight on the affected leg. Treatment options may include rest, physical therapy, and in some cases, surgical intervention.

Chondromalacia

Chondromalacia patella, also known as runner’s knee, is a condition that involves softening and degeneration of the cartilage on the underside of the kneecap. This condition is common among athletes, particularly runners, and can cause pain at the front and back of the knee. Symptoms of chondromalacia patella may include aching or grinding pain in the knee, swelling, and a sense of instability or catching in the knee joint.
