LOOSE BODIES WITHIN THE KNEE (JOINT MICE
Loose bodies in the knee joint are small fragments of cartilage or bone that move freely around the knee in joint fluid, or synovium. They can hinder the joint moment by getting caught in flexion and extension movements. The loose bodies can vary in size from a few millimeters (such as the size of a small pill) to a few centimeters (the size of a quarter). The fragments can lead to damage to the articular cartilage, causing osteoarthritis. Limitation of motion KNEE pain Intermittent joint locking
MCL Sprain
A medial ligament sprain or MCL injury is a tear of the ligament on the inside of the knee, usually a result of twisting or direct impact. Pain KNEE instability 3 grades
Meniscal tear
A meniscus tear is usually caused by twisting or turning quickly, often with the foot planted while the knee is bent. Meniscus tears can occur when you lift something heavy or play sports. As you get older, your meniscus gets worn. This can make it tear more easily. Pain in the knee Limited range of motion Swollen knee
PATELLAR FRACTURES
A patellar fracture is a break in the patella, or kneecap, the small bone that sits at the front of your knee. ... In most patellar fractures, however, the pieces of bone move out of place when the injury occurs. Swelling Pain Deformed
KNEE plica
A plica causes problems when it is irritated. Visible and palpably tender plica Positive duvet test
BURSITIS
Bursitis is most often caused by repetitive, minor impact on the area, or from a sudden, more serious injury. Age also plays a role. As tendons age they are able to tolerate stress less, are less elastic, and are easier to tear. Pain Redness Stiffness Swelling
OSGOOD- SCHLATTER DISEASE
Osgood-Schlatter disease can cause a painful lump below the kneecap in children and adolescents experiencing growth spurts during puberty.
OSTEOCHRONDRITIS DISSECANS
Osteochondritis dissecans (os-tee-o-kon-DRY-tis DIS-uh-kanz) is a joint condition in which bone underneath the cartilage of a joint dies due to lack of blood flow. This bone and cartilage can then break loose, causing pain and possibly hinder joint motion. Pain Swelling Joint popping KNEE Decrease in range of motion
PERONEAL NERVE CONTUSION
This nerve may be injured in a number of ways including injury to the outside of the knee where the nerve is very close to the skin. Swelling, inflammation or infection can also injure the peroneal nerve as can repeated pressure on the outside of the knee from for example sitting with legs crossed in tight clothing. Other injuries can result in nerve injury such as a fracture of the fibula or more seriously a dislocated knee. Damage can also occur during surgery. Swelling Pain Contusions bruising
CHRONDAMALCHIA PATELLA
condition in which the cartilage on the undersurface of the patella becomes softened or damaged. Possible abnormal patellar tracking
JOINT CONTUSIONS
A contusion can result from falling or jamming the body against a hard surface. Contusions cause swelling and pain, and limit joint range of motion near the injury. Torn blood vessels may cause bluish discoloration. The injured muscle may feel weak and stiff . Swelling Pain Contusions
OSTEOCHRONDAL KNEE FRACTURE
An Osteochondral fracture is a tear of the cartilage which covers the end of a bone, within a joint. It is also known as Osteochondritis Dissecans and is common in the knee joint, especially in association with other injuries such as ACL tears. Pain weight bearing Swelling Instability
ACL sprain
An anterior cruciate ligament injury is the over-stretching or tearing of the anterior cruciate ligament (ACL) in the knee. Pain KNEE instability 3 grades
Lcl sprain
An injury to the lateral collateral ligament of the knee can be caused by a varus stress, lateral rotation of the knee when weight-bearing or when the LCL loses it's elasticity caused by repeated stress. Pain KNEE instability 3 grades
Patellar tendonitis
An injury to the tissue connecting the kneecap to the shin bone (patellar tendon).
ACUTE PATELLA SUBLUXATION
Deceleration with simultaneous cutting in opposite direction. Quads pulls the patella out of alignment. Pain swelling
INJURY TO THE INFRAPATELLAR PA
May become wedged between the big and patella. Irritated by chronic kneeling, pressure or trauma Pain Weakness
Pcl sprain
PCL injuries are often due to a blow to the knee while it's bent. Common causes include: Striking the knee against the dashboard during an auto accident Falling on the knee while it's bent Pain KNEE instability 3 grains
Runners knee
Patellofemoral pain syndrome (PFPS), or runner's knee, got its nickname for an obvious and very unfortunate reason—it's common among runners. The stress of running can cause irritation where the kneecap (patella) rests on the thighbone. The resulting pain can be sharp and sudden or dull and chronic, and it may disappear while you're running, only to return again afterward. While biomechanical issues may be to blame for runner's knee, the cause can often be traced back to poorly conditioned quadriceps and tight hamstrings.
PATELLO-FEMORAL STRESS SYNDROME
Patellofemoral stress syndrome is a term used to describe pain in the front part of the knee (medically termed as anterior knee pain) that occurs due to abnormal motion or pressure between the kneecap (patella) and thighbone (femur).
ACUTE PATELLA DISLOCATION
Predisposed injury Repetitive subluxation will impose stress to medial restraints KNEE appeared deformed KNEE swelling
Larsen-Johansson Disease
Sinding-Larsen-Johansson (SLJ) syndrome is a painful knee condition that most commonly affects teens during periods of rapid growth.
PATELLAR TENDON RUPTURE
The patellar tendon ruptures relatively infrequently. However, the complications of an untreated rupture to the extensor mechanism can be extremely disabling. If the tendon does not heal properly and at the correct length and tension, knee range of motion and strength can be altered significantly, leading to early fatigue, [1] patellofemoral pain, and, possibly, instability, which can thereby prevent return to preinjury status.
