knee-pain-blockKnee pain can be nagging or debilitating, and is often caused by injury or disease.  It can affect muscle control in the sore leg, decrease the strength and endurance of the muscles that support the knee, and can restrict mobility as well.  Injuries can occur from a sudden movement that pushes the knee beyond its normal range of movement, or as the result of a direct blow.  This can happen in recreational activities, a fall, a sporting event, or a motor vehicle accident.  As for disease, Osteoarthritis, also known as Degenerative Joint Disease, is the most common one affecting the knee.  This is caused by the cartilage in the knee gradually wearing away, leading to pain and swelling.    If the pain in your knee is a result of an injury, the most likely culprits involve cartilage tears (e.g., meniscus tears) and/or ligament tears (e.g., ACL, or Anterior Cruciate Ligament).  Knee pain can also be caused by repetitive stress, as often occurs with the kneecap (known as PFPS, or, patellofemoral pain syndrome).  Very rarely do knee injuries involve broken bones, with the exception being extreme trauma.

  • Can you point to a specific location of your knee that is painful?
  • Did you twist your knee?
  • Did you feel a “pop” at the time of the injury?
  • Has your knee been swelling?
  • Has your knee “locked?”  Do you feel a “catch?”  Do you feel like your knee will “buckle” or “give out?”
  • Do you experience difficulty with sitting with your knee bent for extended periods of time, such as riding in a car or sitting at the movies?
  • Do you have difficulty with going up and down steps?
  • Do you have increased pain with bending or straightening your knee?
  • Do you experience pain when you pivot? (plant your foot and twist your body).
A thorough evaluation by your Physical Therapist will include testing to determine loss of motion, weakness, swelling, pain, and ligament and cartilage instability.  A gait assessment should also be conducted to determine if you are altering your walking mechanics due to one or more of the objective findings.
     Your Physical Therapist should develop a rehab program for you tailored to your individual needs and goals, based on their findings from their evaluation.  Depending on the severity of your knee problem, your age, your lifestyle, and your goals, your Physical Therapist  should include strength training and functional exercises designed to increase strength, endurance, and function of your leg muscles (quadriceps and hamstrings).  This will help to support the knee and reduce stress to the knee joint without increasing the risk of injury or further damage.  Your Physical Therapist can determine just how much you may need to limit your physical activity involving your affected knee, and will also be able to gauge your knee’s progress in function during your rehabilitation.
     Ideally, everyone should be performing 3 types of exercises to prevent injury to all parts of the body, including knees.  These exercises include:
  • Range of motion or mobility exercises to help maintain normal joint movement and decrease stiffness
  • Strengthening exercises to maintain or increase muscle strength
  • Aerobic or endurance exercises, such as walking or swimming, to improve heart function and promote circulation, as well as to help control weight and prevent obesity.  Weight control is extremely important to individuals with arthritis because extra weight increases pressure on many joints, including the knees
Some things to keep in mind to help keep knee pain from worsening is to make sure you maintain an overall healthy lifestyle, get adequate rest, eat healthy foods, and above all, exercise.  It is also extremely important for runners and other athletes to perform a Physical Therapist approved warm-up and stretching exercise program on a daily basis, especially before beginning physical activity.
