Abstract


Long distance running is becoming more popular. As it is, more races are being run and the intensity is becoming greater. Runners preparing for marathons run over 70 miles a week. As result there are more injuries, especially due to over use. The doctors opened a clinic to evaluate knee injuries of runners who run more thatn 20 miles a week. During the first year 49 of 161 patients complained of disorders in one or both knees. The complaints were classified into three categories: patellofemoral pain, iliotibial pain, and pain related to the lateral or medial femur or tibia.

Fifteen patients complained of patellofemoral pain (18 knees in all). Training error, rapid change in the usual running program, came before 6 of the knee injuries. Genu valgum was indicated in one knee and femoral anteversion in one as well. For all injuries the joint was iced, hamstrings were stretched, and quadratic muscles were strengthened. Activity was restricted to either no running or an alternate exercise. Of all the runners only one completely gave up running to stop the pain.

Fourteen patients complained fo iliotibial pain (16 knees). The symptoms were related to excessive running. Treatment included restricting or changing activities. The patients were given NSAI and learned to stretch the iliotibial band. Only one patient stopped running and only one reduced mileage, the rest resumed full activity.

Twenty-one knees had overuse pain in the medial or lateral surface of the tibia or femur. Treatment consisted of progressive resistive quadriceps strengthening. Patients were prescribed non-steroidal anti-inflammatory medications and were told to restrict or alter activity. Two knees required surgery. Two patients showed no improvement and gave up running. Other than that the patients returned to normal or reduced activity.

Of the three groups symptoms remained in 17 knees. This evaluation found that 25% of patients who run have knee disorders. There are more men with knee injuries than women. The most common disorder is iliotibial pain. The doctors found that runners should not suddenly change their exercise schedual and they should come more aware of the problems that could arise from their sport. Knees are extremely susceptable to injury and should be cared for more carefully.
