Quadriceps tendon rupture - initial program

Quadriceps tendon rupture - initial program

Quadriceps (m. quadriceps femoris) is a four part muscle of the anterior upper leg region and it is considered to be one of the most complex and biggest muscles of the movement system. It is of extreme importance in proper knee joint functionality and stability as well as hip functionality. His function is straightening the knee joint, ie. knee extension and it acts as an antagonist to the function of the posterior upper leg muscles, ie. the hamstrings muscle complex, whose main function is knee joint flexion.

Quadriceps tendon is a place where all four muscle parts get connected into one joint connecting body at the distal anterior part of the femur. The fact that all four quadriceps parts get fused into one tendon which connects and is located in the knee joint region where patella (knee cap) and a series of other ligamentary, tendon, cartilage and muscular structures are situated  speaks enough about the range of possible problems which can occur in that region and on the quadriceps tendon. As stated the quadriceps tendon connects to the upper, proximal part of the patella bone which also has a connecting tendon from its lower, distal part to the tibial tuberosity on the proximal lower leg region.

Quadriceps tendon ruptures can be either partial with only parts of the tendon being torn or complete, where the whole tendon is torn. Most often it occurs with the middle age population during activities that have explosive jumping or running tasks. Treatment of complete tendon ruptures implies surgical reconstruction of the tendon, ie. tendon stitching. Complete tendon ruptures cause loss of knee extension, ie. the tendon disconnects from its connecting point on the tip of the patella. Quadriceps tendon ruptures most often occur in situation when the tendon is already under significant load, the knee is partially bent, the foot planted and then added load is put on the leg which leads to the tendon being torn, eg. during inproper landing after a jump. Ruptures can also occur after a direct blow or fall on the knee, when the tendon has lacerations or is affected by degenerative changes (tendinitis, chronic disease of the tendon tissue, pain syndromes, etc). Weakness, degenerative changes or fatigued  of the tendon can proliferate the possibility of it being injured.

Symptoms that occur are: a snapping sound when the tendon tears, sudden, very sharp and intense pain, swelling, hematoma, a dent at the location of the tear (above the patella), muscle spasm, patella lowering down from its place due to the fact that it is no longer held in place by the quadriceps tendon, inability to extend the knee, inability to walk because the knee buckles and feels unstable.

Complete tednon rupture is treated surgically, the tendon gets reconnected to the tip of the patella with small stitches which go through the tendon at its end and are then pulled through small holes which are drilled through the top of the patella bone. It is important that the surgery takes place as soon as possible so that excesive scar tissue and tednon shortening can be avoided. A newr approach considers using small anchors which connect the tendon to the patella without the need to drill hoes in the patella which makes the healing and the return to full functionality easier and faster. After the surgery it is necessary that the loads on the leg are reduced in order for the tendon to heal as fast and as better as possible. Use of protective leg orthosis which limits the knee range of motion by keeping the leg locked in a straight position and is regulated by the doctor as well as use of crutches or a walker is advised. With time the doctor will progressively increase the angle of the orthosis, ie. the range of motion in the knee joint.

Initial therapy post surgery revolves around reducing pain, swelling and hematoma with use of RICE method (rest, ice, compression, elevation) and leter on in the functional phase of therapy careful and gradual knee range of motion, quadriceps strenght and knee stability should be regained. Quadriceps strenghtening is firstly done through static, isometric exercises, the through dynamic exercises, starting with concentric muscle activity and later when the muscle has laready regained enough strenght through eccentric muscle activity.

Prevention: timely and proper treatment of earlier muscular or tendon injuries and degenerativechanges as well as pain syndromes in the knee region, obtaining optimal muscle elasticity and flexiblity as well as good blood supply in the tendon so that it is not too stiff and therefore more susceptible to tears, proper preactivity warm up, etc.
