Patellar Tendinopathy - Effect of Training and Enhancement of the Collagen Synthesis by Insulin-like Growth Factor-I (IGF-I)

July 28, 2020 updated by: Mette Hansen, Bispebjerg Hospital

Effect of Training and Local Infusion of Insulin-like Growth Factor-I and Training on Tendon Structure in Patients With Patellar Tendinopathy

The purpose of the study is to test the hypothesis that stimulation of the synthesis of new structural tendon proteins combined with training improve the tendon structure in patients with chronic knee tendon pain.
