How can i treat runners knee (knee patellofemoral syndrome)?

Treat cause/symptoms: "runner's knee" is not a specific diagnosis but a term for knee disorders occurring in runners. In general, the reason for the pain is overuse and/or inflammation. General recommendations: avoid the aggravating activity, rest, ice, anti-inflammatory medication, compression/bracing, and time. Once improved, gradual return to running, and increased cross-training, may limit recurrences.
