Summary of all friction coefficients (mean ± standard deviation) obtained during the three different test scenarios: FT-I (FN = const., v acc. to gait cycle), -II (FN acc. to gait cycle, v = const.) and –III (FN and v acc. to gait cycle) for the friction pairings: tibial cartilage (TC), meniscus (M) and the silk fibroin scaffold (S) each against a flat, femoral cartilage sample (FC).
