Individuals with PFP may be exhibit higher pain level and lower function.Magnetic resonance imaging rarely can give useful information for managing patellofemoral pain syndrome and treatment should focus on an appropriate rehabilitation program including correcting strength and flexibility concerns. In the uncommon cases where a patient has mechanical symptoms like a locked knee, knee effusion, or failure to improve following physical therapy, then an MRI may give more insight into diagnosis and treatment. Classification
PFPS is one of a handful of conditions sometimes referred to as runners knee; the other conditions being chondromalacia patellae, iliotibial band syndrome, and plica syndrome. Chondromalacia patellae is a term sometimes used synonymously with PFPS. However, there is general consensus that PFPS applies only to individuals without cartilage damage, thereby distinguishing it from chondromalacia patellae, a condition with softening of the patellar articular cartilage. Despite this distinction, the diagnosis of PFPS is typically made based only on the history and physical examination rather than on the results of any medical imaging. Therefore, it is unknown whether most persons with a diagnosis of PFPS have cartilage damage or not, making the difference between PFPS and chondromalacia theoretical rather than practical. It is thought that only some individuals with anterior knee pain will have true chondromalacia patellae. Differential diagnosis
The diagnosis of patellofemoral pain syndrome is made by ruling out patellar tendinitis, prepatellar bursitis, plica syndrome, Sinding-Larsen and Johansson syndrome, and Osgood–Schlatter disease. Currently, there is not a gold standard assessment to diagnose PFPS. Treatment
A variety of treatments for patellofemoral pain syndrome are available.
Niacin is especially useful for individuals who have a high risk of getting pancreatitis. Fish oil supplement can also be used as it has been shown to incur a significant reduction to both triglyceride and VLDL levels. If properly managed, individuals with familial hypertriglyceridemia have a fairly good prognosis. If therapy is successful, these individuals do not have uncontrolled severe triglycerides and VLDL. It is important to educate individuals on possible secondary causes of elevated lipid profiles. Proper management of the secondary causes provides a good prognosis for overall individual health.
