Knee Tendonitis. Tendonitis can be defined as an inflammatory reaction that occurs in the sheath that surrounds the tendon. The inflammation reaction can also occur in the tendon itself however it has been proposed that the synovial sheath is the main site for the highest inflammatory reaction to occur. Knee tendonitis is the reaction that is occurring in and around the tendons and the sheath surrounding it at the region of patella.
The cause for such a phenomena yet needs to be discovered, however there are many theories in place to explain the multifactorial causes which might lead to this damaging reaction.One of the most popular theories in place is the trauma, according to this in the regions where tendonitis is most likely to occur like the regions of rotator cuff, the Achilles tendon, patellar tendon as well as the knee, and the elbow there is repeated trauma: which might lead to scaring and inflammatory reaction itself. Other factor linked directly to cause of tendonitis is the loss of vascularity, which tend to decrease over a period of time and also decreased exercise which might precipitate the inflammatory condition.
Treatment of this reaction is basically to relieve symptoms; as the exact cause of this reaction is still largely unknown there is no definitive treatment. Treatment involves relief to the injured tendons; this is achieved by bed rest and local application of heat.: However physiotherapists have argued that in a case of acute tendonitis local application of ice has more advantage than heat. NSAIDS might also be prescribed for people who need pain killers. Treatment duration might last up to 7-10 days but repeated sittings are essential and might prolong every 2-3 weeks. Severe inflammation might require localized steroid injection to stop further inflammatory reaction. Surgery is considered for people who have calcific deposits who usually complain of persistent pain even after physiotherapy.
Patello femoral pain, or commonly known as runners knee is characterized by pain in the region of knee. The cause for such pain is not tendonitis but unusual congenital disease in which the knee bone known as patella is placed very high.: This leads to tightness in the tendons which articulate at the patella. The tendons affected are the Vastus Lateralis, Vastus Medialis, Iliotibial tract, lateral retinaculam. However there is also tightness noticed on the heel cordis, and weakness in the vastus medialis. The hall mark observation point in this disease is when one tries to pronate the lower leg twists medial, while the quadriceps muscles start acting. Here out of four 3 muscles pull the patella bone laterally but due to weakness of vastus medialis it pulls medially. The combination of this action results in a lateral pull of the knee bone- patella which is combined with excessive pronation. During such motion the patella tends to rub the lateral condoyle of the thigh bone- femur. During a prolonged period of time due to such repetitive action the pain becomes excessive and results in debilitating the person. This is seen in runners as the motion is most commonly seen in runners.
