Abstract

OBJECTIVES:

To investigate pain level and function limitation in adolescent athletes and physically active non-athletes with PFP.

DESIGN:

Cross-sectional study.

SETTING:

Adolescent athletes were recruited at a sport center complex. Adolescent non-athletes were recruited from upper secondary schools.

PARTICIPANTS:

108 adolescents diagnosed with PFP: 42 adolescent athletes and 66 adolescent non-athletes.

MAIN OUTCOME MEASURES:

To evaluate the level of pain, a visual analog scale (VAS) was used and to evaluate the overall function, the Knee Outcome in Osteoarthritis Survey (KOOS) was used.

RESULTS:

The adolescent athletes scored significantly higher in the VAS (Mean difference = 0.97 (95% CI = 0.35; 1.60) p = 0.003) compared to adolescent non-athletes. Adolescent athletes scored lower in the KOOS - Symptoms, Pain, Knee-related quality of life and Sport and recreation dimensions - than the non-athletes, however, the minimally clinically important difference was not achieved in Pain dimension. There was no significant difference in the Activities of daily living dimension of the KOOS.

CONCLUSIONS:

Adolescent athletes presented higher levels of pain and lower physical function status compared with physically active non-athletes. This provides an important insight to the management of PFP in adolescent athletes as worst functional status is linked with poor prognosis in patients with PFP.
