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.

Introduction. Despite the fact that instability of the patella is a common pathology within the structure of knee joint diseases and injuries in children, currently there is no complete information on the basis of which one could judge the effectiveness and preference of a particular method of treating instability of the patella in children. Purpose of study: to evaluate the efficacy of surgical treatment techniques in children with post-traumatic instability of the patella. Patients and methods. The study was performed on the basis of examination and treatment data on 127 patients aged from 8 to 17 years with post-traumatic instability of the patella. Arthroscopic stabilization by Yamamoto technique, modified at our department, was performed in 49 patients, patella stabilization with transposition of the tibial tuberosity - in 67 patients, with the medial patellofemoral ligament autoplasty - 9, corrective osteotomy - in 2. Treatment efficacy was assessed using AKPS and 2000 IKDC knee joint assessment scores. The questionnaires were carried out at admission, in 1, 2-4 and 4-7 years after surgery. Results. At early terms after operation (up to 2 years) in the group of children after stabilization of the patella by modified Yamamoto technique good and excellent results were observed in 77.8% of cases, after transposition of the tibial tuberosity - in 73.3%, after stabilization of the patella with medial patellofemoral ligament autoplasty - in 88.9%. Long-term follow up (5-7 years) showed 90.9 and 86.5% of cases from the 1st and 2nd groups, respectively. Conclusion. The proposed algorithm for examination and treatment provides the most effective treatment and enables to obtain good and excellent results in the majority children with post-traumatic instability of the patella.

Robust preclinical test methods involving tribological simulations are required to investigate and understand the tribological function of osteochondral repair interventions in natural knee tissues. The aim of this study was to investigate the effects of osteochondral allograft implantation on the local tribology (friction, surface damage, wear and deformation) of the tissues in the natural knee joint using a simple geometry, reciprocating pin-on-plate friction simulator. In addition, the study aimed to assess the ability of osteochondral grafts to restore a low surface damage, deformation and wear articulation when compared to the native state. A method was developed to characterise and quantify surface damage wear and deformation of the opposing cartilage-bone pin surface using a non-contacting optical profiler (Alicona Infinite Focus). Porcine 12 mm diameter cartilage-bone pins were reciprocated against bovine cartilage-bone plates that had 6 mm diameter osteochondral allografts, cartilage defects or stainless steel pins (positive controls) inserted centrally. Increased levels of surface damage with changes in geometry were not associated with significant increases in the coefficient of dynamic friction. Significant damage to the opposing cartilage surface was observed in the positive control groups. Cartilage damage, deformation and wear (as measured by change in geometry) in the xenograft (2.4 mm3) and cartilage defect (0.99 mm3) groups were low and not significantly different (p > 0.05) compared to the negative control in either group. The study demonstrated the potential of osteochondral grafts to restore the congruent articular surface and biphasic tribology of the natural joint. An optical method has been developed to characterise cartilage wear, damage and deformation that can be applied to the tribological assessment of osteochondral grafts in a whole natural knee joint simulation model.

Background: the main goal of the study was to investigate the prevalence of the articular cartilage defects (ACD) in the patellofemoral (PF) region of the knee joint based on the anatomical shapes of patella and its impact on the level of physical activity in the population needing arthroscopic procedures for all types of pathologies in the knee. Methods: The articular cartilage status of the PF region was obtained from 1098 arthroscopic procedures of the knee joint. The ACD were correlated to Wiberg’s shape of the patella and classified according to the degree, size and depth of the ACD in the PF region using the ICRS (International Cartilage Repair Society) system: group I consisting of patients with Wiberg type I shape (W1), group II—patients with Wiberg type II shape (W2) and group III—patients with Wiberg type III shape (W3). The Tegner physical activity scale was used to evaluate the physical activity of the patients. Results: The mean of ACD size (PF region) in the W3 group was 3.10 ± 0.99 cm2, which was a statistically significantly larger area in comparison with the W1 (1.90 ± 0.63 cm2; p < 0.0000) and W2 (1.95 ± 0.71 cm2; p < 0.0000). The patients from the W3 group (mean 3.10 ± 0.99) were less physically active (<4 Tegner) compared to the W2 group (mean of 4.48 ± 0.88; p = 0.004) and W1 group (mean of 4.55 ± 0.72; p = 0.002). Conclusions: The patients with the Wiberg type III patella shape had a higher incidence and larger size of ACD in the PF of the knee compared to the groups of Wiberg type I and II. Wiberg III patients with a lower level of physical activity had a larger size of ACD in the PF joint.
