Patellar Dislocation - Osmosis Patellar dislocation is a relatively uncommon knee injury Only accounting for approximately 2–3% of all knee injuries, patellar dislocations most commonly affect young and active individuals, with a higher risk among adolescent females and athletes
Chondromalacia Patellae - Osmosis Chondromalacia patellae may be caused by several etiologies including weakness of the core and thigh muscles; recurrent joint injuries or trauma, such as repetitive bending or twisting of the knee joint during sports; or iatrogenic injection of medications (e g , steroids) into the knee joint Weakness or imbalance of any of the major thigh muscles (e g , pectineus, sartorius, or quadriceps
Patellar tendon rupture: Video, Causes, Meaning | Osmosis Patellar tendon rupture is a rupture of the tendon that connects the patella to the tibia The tell-tale sign of a ruptured patella tendon is the movement of the patella further up the quadriceps When rupture occurs, the patella loses support from the tibia and moves toward the hip when the quadriceps muscle contracts, hindering the leg's ability to extend This means that those affected
Quadriceps Tendonitis: What It Is, Causes, Symptoms, Treatment - Osmosis Quadriceps tendonitis, also known as “jumper’s knee,” is a musculoskeletal condition characterized by inflammation of the quadriceps tendon The quadriceps tendon connects the quadriceps muscles located at the front of the thigh to the patella, or kneecap The patellar tendon then connects the patella to the tibia, or shinbone Collectively, the quadriceps tendon and patellar tendon
Anatomy of the knee joint: Video, Causes, Meaning | Osmosis The patellar ligament, the distal part of the quadriceps femoris tendon, is a thick fibrous band passing from the apex and adjoining margins of the patella to the tibial tuberosity
Osgood-Schlatter disease (traction apophysitis) - Osmosis Osgood-Schlatter disease is an inflammation of the patellar tendon, right at the point where it inserts on the tibial tuberosity, resulting in painful swelling just below the knee It’s named after two orthopedic surgeons; the American Robert Osgood, and the Swiss Carl Schlatter
Special tests for the lower limb - Osmosis Patellar grind test With the patient supine and the knee flexed to 10–20º, grasp the distal thigh and proximal patella, apply anterior to posterior pressure on the patella, and instruct the patient to contract the quadriceps muscle
Hyporeflexia: What Is It, Causes, Important Facts, and More | Osmosis Hyporeflexia is diagnosed through a neurological examination that evaluates the deep tendon reflexes (DTRs) using a reflex hammer Some of the common reflexes tested include the biceps, brachioradialis, and triceps reflexes in the arm, as well as the patellar and Achilles reflexes in the leg Normally, tapping the reflex hammer at specific tendon should elicit an immediate contraction in the
Somatic Reflex: What Is It, Types, and More | Osmosis The most commonly identified type of stretch reflex is the knee jerk reflex, where tapping the patellar tendon (i e , the tendon located at the front of the knee) causes the foot to kick forward This reflex is a type of deep tendon reflex tested during a neurological examination to identify abnormalities within this reflex arc
Patellar tendon rupture: Vídeo, Anatomía Definición | Osmosis Patellar tendon rupture is a rupture of the tendon that connects the patella to the tibia The tell-tale sign of a ruptured patella tendon is the movement of the patella further up the quadriceps
