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.

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.

The long-term results of conservative and surgical treatment of 200 patients with closed uncomplicated fractures of the thoracic spine were analyzed and tables of the frequency of signs that characterize this group of patients were compiled. Based on the data obtained, tables were compiled for the computational prediction of the outcomes of closed uncomplicated fractures of the thoracic spine with conservative and surgical treatment. The use of computational prediction tables in the practice of medical institutions will make it possible to objectively assess the condition of the victim, determine the effectiveness of a particular treatment method and recommend the most appropriate one.

Background: Sticker sarcoma, also called venereal sarcoma or venereal lymphosarcomatosis, is a tumor of the external genital organs in females and males. In male animals the penis and foreskin (prepuce) are affected, in the female, it happens in vagina (vagina) and labia (vulva). The diagnosis of sticker sarcoma is based on the chronic discharge, the typical locations and the characteristic appearance of the tumor. Methods: We have relied on the treatment method on the complete surgical removal of all cancer cells that we can access. Results: After surgery, we notice recurrent tumors about six months after surgical treatment, indicating the need for other treatments in addition to surgery. Conclusion: Although spontaneous regressions of sticker sarcoma are documented (with permanent immunity), chemotherapy is the treatment of choice today. Irradiation should also be effective. If the tumor is only removed surgically, there is a high rate of recurrence, and this is what happened with the case that we treated, as the tumor reappeared after less than six months.

Multiple traumatic hematomas (MG) account for 0.74% of all traumatic brain injuries. A comprehensive diagnostic approach to multiple traumatic intracranial hematomas allows to establish a diagnosis in the early stages of traumatic brain injury and to determine treatment tactics. A differentiated approach to the choice of surgical treatment of multiple hematomas allows to achieve satisfactory results and treatment outcomes, which accordingly contributes to the early activation of the patient, a reduction in hospital stay, a decrease in mortality and disabilityin patients with traumatic brain injury

Objective Focal cartilage injuries are debilitating and difficult to treat. Biological cartilage repair procedures are used for patients younger than 40 years, and knee arthroplasties are generally reserved for patients older than 60 years. Resurfacing implants are well suited for patients in this treatment gap. The objective was to investigate the 10-year survival of resurfacing implants in the Danish Knee Arthroplasty Registry. Design In this retrospective cohort study, patients treated with resurfacing implants were followed longitudinally in the Danish Knee Arthroplasty Registry from 1997 to 2020. The primary endpoint was revision surgery. The survival of the resurfacing implants was analyzed by Kaplan-Meier method. Results A total of 379 resurfacing implant procedures were retrieved from the Danish Knee Arthroplasty Registry. The mean age and weight of patients were 50 years (SD = 11) and 84 kg (SD = 17), respectively. The indications for surgery were as follows: secondary osteoarthritis (42%), primary osteoarthritis (32%), and osteochondral lesions (20%). Within the follow-up period, 70 (19%) of the implants were revised to arthroplasties. The 1-, 5-, and 10-year revision-free survival estimation was 0.95 (95% CI 0.93-0.97), 0.84 (95% CI 0.80-0.88), and 0.80 (95% CI 0.75-0.84), respectively. The median time to revision was 2 years. Conclusion The 10-year revision-free survival rate for resurfacing implants was 80%. Based on the revision rates, this treatment offers a viable alternative to biological cartilage repair methods in patients aged 40 to 60 years with focal cartilage pathology. Improved patient selection could further improve the implant survival rate. Further studies are needed to investigate this treatment method.
