Opioid replacement therapy
According to a Cochrane review in 2013, extended-release morphine as an opioid replacement therapy for people with heroin addiction or dependence confers a possible reduction of opioid use and with fewer depressive symptoms but overall more adverse effects when compared to other forms of long-acting opioids. The length of time in treatment was not found to be significantly different. References

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.
