Introduction. To investigate the clinical results of arthroscopic management for the unstable inferior leaf of the lateral meniscus anterior horn and associated cysts through an inframeniscal portal. Methods. From March 2005 to October 2014, 64 patients with an unstable inferior leaf of the lateral meniscus anterior horn and associated cysts underwent arthroscopic management with an inframeniscal portal. The mean age of the patients was 36.9 years (range, 18 to 49 years). The mean follow-up period was 28 months (range, 24 to 44 months). Clinical results were assessed using physical examination, the Lysholm knee score, and postoperative magnetic resonance scanning. Results. The median Lysholm score improved significantly at 1 year after surgery and at final follow-up. Magnetic resonance scanning at least one year after the operation revealed no recurrent meniscal tears or cysts. No reoperations were required after an average follow-up of 28 months. All patients reported significant symptomatic relief after the operation. They had full range of motion at three months and returned to normal activities and sports one year after surgery. Conclusion. The direct inframeniscal portal can provide an effective approach to manage lesions in the anterior horn of the lateral meniscus with predictable clinical outcomes.

AbstractThe study evaluates the meniscal tissue after primary meniscal suturing using 7-Tesla (T) magnetic resonance imaging with T2* mapping at 6 and 12 months after surgery to investigate the differences between repaired meniscal tissue and healthy meniscal tissue in the medial and lateral compartment. This prospective study included 11 patients (9m/2f) with a mean age of 30.6 years (standard deviation 9.0). Patients with a meniscal tear that was treated arthroscopically with meniscus suturing, using an all-inside technique, were included. All patients and seven healthy volunteers were imaged on a 7-T whole-body system. T2* mapping of the meniscus was applied on sagittal slices. Regions-of-interest were defined manually in the red and white zone of each medial and lateral meniscus to measure T2*-values. In the medial posterior and medial anterior horn similar T2*-values were measured in the red and white zone at 6- and 12-month follow-up. Compared with the control group higher T2*-values were found in the repaired medial meniscus. After 12-months T2*-values decreased to normal values in the anterior horn and remained elevated in the posterior horn. In the red zone of the lateral posterior horn a significant decrease in the T2*-values (from 8.2 milliseconds to 5.9 milliseconds) (p = 0.04), indicates successful repair; a tendency toward a decrease in the white zone between the 6 and 12 months follow-up was observed. In the red zone of the lateral anterior horn the T2*-values decreased significantly during follow-up and in the white zone of the lateral anterior horn T2*-values were comparable. In comparison to the control group higher T2*-values were measured at 6-months; however, the T2*-values showed comparable values in the repaired lateral meniscus after 12 months. The T2* mapping results of the current study indicated a better healing response of the red zone of the lateral posterior horn compared with the medial posterior horn.

Annotation. Among the large joints, the knee joint is most often injured, which is due to the peculiarities of its structure and functional loads in the process of human life. The most common injuries are meniscus damages of the knee joint, that is the evidence of steady increase in the number of partial arthroscopic meniscectomies, which have become the most common orthopedic procedure. Diagnosis of meniscus damage is based on the results of clinical examination, sonography and MRI. Increasing the resolution of MRI machines, improving the technique of their implementation allows to improve the quality of diagnosis of meniscus ruptures and improve the results of surgical arthroscopic interventions on the knee joint. The aim of the study – to demonstrate the capabilities of high-intensity 1.5 Tesla MRI and to study the reliability of MRI signs of meniscus damage in comparison with the results of arthroscopic interventions in acute and chronic knee joint injury. The work is based on the results of MRI examinations and arthroscopic interventions of 247 patients with acute and chronic knee joint injuries aged 14 to 59 years. Medial meniscus damage was diagnosed in 206 (83.41%) patients. Lateral meniscus ruptures were diagnosed in 34 patients (13.76%). Simultaneous damage of both menisci was found in 7 (2.83%) patients. It was found that ruptures of the medial meniscus by location were: the root of the posterior horn of the medial meniscus in 4 (1.94%) patients, ruptures of the posterior horn in 82 (39.81%) patients. Injury of the posterior horn with the transition to the body of the meniscus was diagnosed in 117 (56.79%) patients. Anterior horn ruptures were detected in 3 (1.46%) patients. With ruptures of the lateral meniscus: damage of the root of the posterior horn of the lateral meniscus was found in 2 (5.88%) patients, damage of the posterior horn in 9 (26.47%) patients. Posterior horn rupture with transition to the body of the meniscus was diagnosed in 19 (55.89%) patients. Isolated ruptures of the anterior horn were found in 4 (11.76%) patients. Simultaneous damage to both menisci was found in 7 (2.83%) patients. 206 (83.40%) partial meniscectomies were performed during arthroscopic interventions and meniscus suturings were performed over 41 (16.60%) patients. In order to identify meniscus damage and their location during MRI knee joint investigations 21 pseudo-positive and 18 pseudo-negative cases of diagnosis were revealed. The sensitivity of MRI for defining damage and localization of meniscus rupture was 91,7%, specificity 92,6%, diagnostic accuracy 94,8%. Discrepancies in the evaluation of meniscal damage most often occurred in cases of their combined ruptures and degenerative changes in the menisci.
