Background:
Anterior knee pain (AKP) is a common knee problem seen in ado-
lescents and young adults characterized by non- specific knee pain, pain when
climbing stairs, riding a bike, walking and running. This leads to an impairment of
both recreative and activities of daily living.
Purpose / Aim of Study:
The purpose of the present study is to investigate
the effect of a 3 months multimodal intervention including AKP- education,
exercise program, footwear adjustment and foot orthoses in AKP patients.
Materials and Methods:
42 patients (Age 19 (10-32)) with the diagnosis
AKP were included in a consecutive prospective cohort. The patients were edu-
cated in AKP and were instructed in a 3 months exercise program focusing on
hip abduction, hip external rotation and normal movement pattern. Footwear
was adjusted (for patients with angle valgus) and foot orthoses were recom-
mended to patients with too much foot roll (pronation). Kujala score and Pain
numeric rating scale (NRS) were used to evaluate the effects of intervention.
Intraarticular knee pathology was excluded by MRI and clinical examination.
Findings / Results:
The Kujala score improve from 71 to 86 months after 3
months. The NRS- rest and NRS-Walk improve from 3.0 to 1.3 and 6.4 to 3.0
respectively. All improvement are statically significant (p<0.01). 55% of the pa-
tients have at clinical improvement (>10 points on the Kujala score) and 57%
and 74% had a clinical improvement on the NRS-rest and NRS-walk, respec-
tively (≥ 2 points improvement). None of the patients have a decrease in out-
come scores after 3 months.
Conclusions:
An AKP multimodal treatment strategy focusing at footwear, or-
thoses and simple hip muscle exercise the patient significantly improve func-
tional outcome and reduce pain. Further investigation is needed to evaluate the
long time follow up.
