FILEX 2015 PRESENTER & REHAB WHEN KNEE PAIN IS NOT JUST KNEE PAIN! Knee pain can be caused by a number of factors – and it doesn’t always ‘just go away’ with rest. WORDS: THUY BRIDGES 1 Gracilis Photos from upcoming Elsevier book Length, Strength and Kinesio Taping by Thuy Bridges 2 here are many causes of medial knee pain and an incorrect diagnosis may inadvertently lead to poor management of symptoms and a delayed recovery. In this issue we look at pes anserine bursitis: the ‘other’ knee pain. T Pes anserine Pes anserine is the anatomic term used to identify where the tendons of gracilis, sartorius, and semitendinosus muscles attach to the tibia, just below the knee. The word literally means ‘goosefoot’ as it describes the appearance of these three tendons at the attachment point. The pes anserine bursa provides a lubricant/buffer between the ligament and the tendons. How does it occur? Sartorius 3 Semitendinosus The three muscles mentioned above are primarily flexors of the knee, and also induce internal tibial rotation, protecting the knee against rotary and valgus stress. Bursitis arises due to undue stress being placed on the area at which these muscles attach. Overuse of the hamstrings in runners with particularly tight hamstrings is common in cases of pes anserine bursitis. In addition to trauma, sudden changes in training, improper training, ‘cutting’ training (exercise performed in a sideways motion that places a high lateral strain on the knee) and running up hills can contribute to the condition. The bursa becomes irritable and inflamed NETWORK AUTUMN 2015 | 23
