Quadriceps tendon rupture; Other names: Quadriceps tendon tear: An x-ray demonstrating quadriceps tendon rupture. Note the abnormal angle of the patella and soft-tissue swelling marked by the arrow. Specialty: Orthopedic
A tendon connects muscle to bone, while a ligament connects bone to bone. [1] Injuries are common to this tendon, with tears, either partial or complete, being the most common. If the quadriceps tendon is completely torn, surgery will be required to regain function of the knee. [2] Without the quadriceps tendon, the knee cannot extend.
Quadriceps dominance refers to a tendency of female athletes to preferentially use the quadriceps muscles to stabilize the knee joint. [17] Given that the quadriceps muscles work to pull the tibia forward, an overpowering contraction of the quadriceps can place strain on the ACL, increasing risk of injury.
Tendon rupture. Tendon rupture is a condition in which a tendon separates in whole or in part from tissue to which it is attached, or is itself torn or otherwise divided in whole or in part. [1] [2] Examples include: Achilles tendon rupture; Biceps tendon rupture; Anterior cruciate ligament injury; Biceps femoris tendon rupture and Quadriceps ...
If the tendon rupture is a partial tear (without the two parts of the tendon being separated), then non-surgical methods of treatment may suffice. The future of non-surgical care for partial patella tendon ruptures is likely bioengineering. Ligament reconstruction is possible using mesenchymal stem cells and a silk scaffold. [5]
This treatment should be incorporated with traditional physical therapy in the postoperative acute setting. [72] Cryotherapy or 'cold therapy' is recommended after surgery for pain relief and to limit swelling of the knee. Knee edema appears in the hours or days following the operation. It reaches its maximum level 3 to 8 days after the surgery.
The patellar tendon is a strong, flat ligament, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface; below, it inserts on the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the quadriceps femoris.
Knee pain is thought to be primarily associated with specific quadriceps muscle weakness or fatigue, especially in the vastus medialis obliquus (VMO).It is known that fatigue can be caused by many different mechanisms, ranging from the accumulation of metabolites within muscle fibers to the generation of an inadequate motor command in the motor cortex.
