BACKGROUND: The treatment of traumatic and degenerative cartilage damage is one of the largest areas in orthopedic practice, and the therapy success remains limited. AIM: To analyze the results of surgical treatment of patients with traumatic and degenerative injuries of the knee joint hyaline cartilage using debridement and osteoperforative techniques, taking into account the time from the surgical intervention. MATERIALS AND METHODS: A statistical analysis was conducted on the treatment outcomes of servicemen with traumatic and degenerative damage in the knee joint articular hyaline cartilage. Patients underwent surgical treatment using osteoperforative techniques (abrasive chondroplasty, tunneling, and microfracturing) at the Clinic of Military Traumatology and Orthopedics of the S.M. Kirov Military Medical Academy from 2009 to 2019. The study relied on the data obtained from questioning the patients using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and LKSS questionnaires. RESULTS: The result analyses using the KOOS and LKSS scales revealed significantly higher good results in the observed group in the postoperative period from 1 to 4 years than in the groups from 4 to 8 and more than 8 years (p = 0.004). No significant differences were determined in the treatment outcomes of the groups with resection and different osteoperforative methods. CONCLUSIONS: Treatment methods for hyaline cartilage defects, such as resection and osteoperforative, are technically simple with good treatment outcomes in patients with articular cartilage injuries from 1 to 4 years postoperative. Treatment outcome deterioration was noted in 48 years postoperative, regardless of the treatment method used, which is more significant in patients in 8 years postoperative.
