Autologous lysed platelets were injected and a clinical follow up using variables such as pain, joint mobility, muscular strength and functional scale. A database was filled for statistical processing. It were calculated statistical measures. Results: out of the 20 patients 14 were male and 6 female, age 39 to 81. 35 knees were injected.
