Snapping hamstrings are a rare condition, but they can cause significant disability in patients who have this pathology.
Lateral, or biceps, snapping hamstrings are usually due to a presumed genetic or injured state where the direct arms of the long and short heads of the biceps no longer attach to the posterolateral aspect […]
Runners knee refers to a junk-basket term of multiple pathologies that can cause knee pain. Most commonly they are due to an overuse-type problem, whereby a few of the hamstrings become too tight or a quadriceps becomes weak and the tissues around the knee become irritated. This can also include overuse-type syndromes, […]
Ehlers-Danlos Syndrome (EDS) is a group of genetically inherited diseases that involve soft connective tissue by disrupting the production of normal collagen. Ehlers-Danlos syndrome is characterized by the fragility of soft tissue and widespread manifestations in skin, ligaments, joints, blood vessels, and internal organs.

Arthrofibrosis of the knee is a condition whereby knee motion is limited due to scar tissue, contractures after injury or surgery, or due to the effects of osteoarthritis over time. There are 2 types of motion that we usually think of as being important to assess knee arthrofibrosis. First, a lack […]
Knee pain is a debilitating symptom associated with knee injuries. While some knee injuries are cut and dry, others are not. Knee pain may derive from damage to the soft tissue or connective tissue of the knee joint, as well as from one or more of the nerves that reside within the knee. While these […]
Tibial plateau fractures are caused by a force driving the lower end of the femur (thigh bone) into the soft bone of the tibial plateau.
One area of the knee that is not discussed as often as some of the other components, is a section called the trochlea. This area of the knee is easy to identify. When the knee is bent, the undersurface of the kneecap (the patella) lies in an area known as […]
In the past, any type of pain over the anterior aspect of the knee was commonly called patellofemoral chondromalacia. However, patellofemoral chondromalacia is a specific term describing a particular pathology/injury that should only be used in cases with this problem.
Chondromalacia, or damage to the cartilage, is the formation of early arthritis. Any […]
Lateral patellar instability is almost always due to a patellar (kneecap) dislocation. In this circumstance, an athlete or patient will experience their kneecap slipping out of the lateral (outside) aspect of their knee. It almost always occurs with the knee straight or at shallow degrees of knee flexion rather than with […]
A bipartite patella forms when a portion of the patella does not completely heal along the bony edges of the patella. Most commonly, this is in the upper and outer (superolateral) portion of the patella. Bipartite patella is quite common, usually asymptomatic, and is found in 2% of the population on x-rays. […]
