Runner’s Knee and Sciatica Symptoms


Runner’s knee is a term commonly utilized to characterize a variety of health issues which can ultimately cause pain, discomfort, and other symptoms around the kneecap also referred to as the patella. These health issues include anterior knee pain syndrome, patellofemoral malalignment, chondromalacia patella, and iliotibial band syndrome.  


Runner’s knee commonly occurs in athletes, especially runners, however, any type of exercise or physical activity which repeatedly stresses the knee joint could cause the health issue. This may include walking, skiing, biking, jumping, cycling, and playing soccer. According to the Harvard Medical School, runner’s knee is more prevalent in women than in men.  


What are the Symptoms of Runner’s Knee?


The most common symptoms associated with runner’s knee includes is a dull, aching pain around or behind the kneecap, also referred to as the patella, especially where it meets the lower region of the thighbone or femur. You may feel pain when:  


  • Walking
  • Climbing (or descending) stairs
  • Squatting
  • Kneeling
  • Running
  • Sitting down or standing up
  • Sitting for extended periods of time with the knee bent
  • Other symptoms include swelling and popping or grinding in the knee.


In the case of iliotibial band syndrome, the pain is most intense on the exterior region of the knee. This is where the iliotibial band, which runs from the hip to the lower leg, connects to the tibia, or the thicker, inner bone of the lower leg.  


Moreover, the symptoms commonly associated with runner’s knee can also ultimately affect an individual’s gait, or manner of walking, and even their posture while standing or walking. These changes can cause the structures of the human body to compensate for the altered functions, resulting in a variety of health issues, such as low back pain and sciatica.  


What are the Causes of Runner’s Knee?


The pain and discomfort of runner’s knee may be brought on by the irritation of the complex soft tissues or lining of the knee, and worn or torn cartilage, as well as strained tendons. Any of the following causes can cause runner’s knee, including:  


  • Overuse
  • Trauma or injury to the kneecap
  • Misalignment of the kneecap
  • Complete or partial dislocation of the kneecap
  • Flat feet
  • Weak or tight thigh muscles
  • Insufficient stretching before exercise or physical activity
  • Arthritis
  • A fractured or broken kneecap
  • Plica syndrome or synovial plica syndrome, where the lining of the joint becomes thickened and inflamed


Occasionally, the painful symptoms can originate in the lower back and hip into the knee. This is known as “referred pain.”  


How is Runner’s Knee Diagnosed?


To determine a diagnosis of runner’s knee, the healthcare professional requires a complete medical history and a thorough physical evaluation which may often include blood tests, X-rays, MRI scans, or CT scans for an accurate diagnosis.  


What is the Treatment for Runner’s Knee?


The healthcare professional will determine the best treatment approach depending on the cause of runner’s knee, however in most instances, runner’s knee can be treated without surgery. Most often, the initial step in treatment is to utilize RICE:  


  • Rest: Avoid repetitive pressure on the knee.
  • Ice: Decrease pain and swelling by applying an ice pack and prevent heat to the knee.
  • Compression: Wrap the knee utilizing an elastic bandage or sleeve to restrict swelling.
  • Elevation: Place a pillow under the knee when sitting or bending down to prevent further swelling. If there is considerable swelling, maintain the foot raised above the knee and the knee above the level of the heart.


Over-the-counter nonsteroidal anti-inflammatory drugs or NSAIDs, such as aspirin, ibuprofen, and naproxen can also help further reduce pain, discomfort, and swelling. Acetaminophen can also help reduce symptoms. You may want to speak with your doctor before taking these medications, especially if you have other health issues or take other prescription drugs.  


The healthcare professional may also recommend stretches and exercises to improve strength and range of motion. They may tape your knee or provide you with a brace to offer additional pain relief. You may also utilize custom foot orthotics to support your knee. Surgery may be recommended if your cartilage is damaged or if your kneecap has to be realigned.  


How Can Runner’s Knee be Prevented?


The American Academy of Orthopaedic Surgeons recommends these methods and techniques to prevent runner’s knee:  


  • Stay in form. Ensure that your overall health and wellness is good. If you are overweight, speak with your healthcare professional about developing a customized weight loss program.
  • Stretch. Do a five-minute warmup followed by stretching exercises before you run or perform any physical activity which adds pressure to the knee. Your doctor can show you how to improve your knee’s flexibility.
  • Gradually increase training. Never suddenly increase the intensity of your workout. Instead, make gradual changes.
  • Use proper footwear. Purchase quality shoes with good shock absorption, and be sure they fit properly and comfortably. Don’t run in shoes which are too worn out. Wear custom foot orthotics if you’ve got flat feet.
  • Use the proper running form. Keep a tight core to prevent yourself from leaning too far forward or backward and keep your knees flexed. Attempt to run on a soft, smooth surface. Prevent running on concrete. Walk or run in a zigzag pattern when moving down a steep incline to avoid adding unnecessary pressure on your knees and feet.
