Follow-up

Further Inpatient Care

  • The standard procedure for treatment of individuals with patellofemoral syndrome is performed on an outpatient basis. Inpatient care generally is not indicated.

Further Outpatient Care

  • Allow time for conservative measures (eg, exercise) to have a therapeutic effect in patients with patellofemoral syndrome. A period of 4-6 weeks usually is adequate for some resolution of symptoms. Longer delays before follow-up often result in reduced compliance with treatment recommendations. Reinforcement of treatment goals and strategies is important.

Inpatient & Outpatient Medications

  • Outpatient medications for individuals with patellofemoral syndrome include common analgesics or NSAIDs (see Medication). Most individuals manage without medication once initial symptoms have been controlled.

Deterrence

  • Prevention of patellofemoral syndrome (PFS) is accomplished by following exercise recommendations and making changes in activity, as described in previous sections. In female athletes, decreased hamstring-to-quadriceps strength ratios have been associated with an increased prevalence of overuse injuries, suggesting that maintaining adequate hamstring strength may act as a preventative strategy. Braces have been tried on asymptomatic subjects undergoing rigorous basic military training, with a subsequent decrease in the incidence of PFS compared with the subject population that did not use the braces.

Complications

  • Complications in patients with patellofemoral syndrome may result secondary to the effects of NSAID use. Occasional dermatologic reactions occur due to the brace material. Prescribed exercises rarely result in aggravation of symptoms. If a specific activity is determined to be associated with aggravation of symptoms, then accordingly modify the frequency, duration, and intensity of the activity

Prognosis

  • The prognosis for full functional recovery in cases of patellofemoral syndrome is very good. In general, this syndrome is successfully treated with conservative measures. Because the prognosis is so good, refractory cases should be closely reviewed with regard to compliance and understanding of treatment recommendations.

Patient Education

  • Educate the patient so that he/she understands which activities aggravate patellofemoral syndrome. In addition, emphasize the need for extended adherence to the exercise regimen. The patient's physical therapist should educate the patient about a home exercise program, making sure the patient has a good understanding of the exercises.
  • For excellent patient education resources, visit eMedicine's Foot, Ankle, Knee, and Hip Center, Arthritis Center, and Osteoporosis and Bone Health Center. Also, see eMedicine's patient education article Knee Pain.

Miscellaneous

Medicolegal Pitfalls

  • The most common medical/legal aspects related to patellofemoral syndrome are defining the nature of the syndrome, its effect on usual activities, and the prognosis in cases in which onset has occurred as a result of trauma (eg, a work-related injury, an automobile-related injury). More specifically, cases in which a direct blow has resulted in an impairment of the cartilage surface may not respond in the same manner as tracking problems. Contusion secondary to dashboard contact, termed dashboard knee, remains a common cause of ongoing knee pain after trauma resulting from a motor vehicle accident.

Special Concerns

  • The primary significant concern associated with patellofemoral syndrome is that the patient remain active and continue to interact with peers. This goal can be accomplished by making sure the affected youth understands the aggravating and alleviating factors associated with participation in sports and other physical activities. If some athletic activities must be curtailed, ideally there should be an attempt to engage the patient in alternative activities to maintain conditioning (eg, swimming). Long-term goals should include resumption of the patient's preferred activities when this is feasible.
