Participants: male athletes (average age - 24.52 ± 3.36 years) from team sports (group 1 (G-1) - n = 13) and martial arts (group 2 (G-2) - n = 13). All participants (n = 26) were questioned about complaints associated with knee injury. Biopsy materials were obtained during arthroscopic interventions. The quantitative ratio of collagen fibers in the fibrous layer of hyaline cartilage was evaluated. For the purpose of morphometry and data evaluation the van Gieson method was used along with observational microscopy and microphotography. Results. There was a significant (p
