Walking restoration is the main request of the patients of traumatologic and orthopedic profile at the final stage of the treatment. The emergence of technologies using inertial sensors allowed to increase clinical availability of the methods of objectification of functions, including knee joint (KJ) functions. The determination of the peculiarities of walking parameters would allow to expand undertaking of functional changes, to use them in the assessment of the effectiveness of various medical technologies of treatment and rehabilitation. Objective − to study time features of walking in patients with long-standing KJ injuries. Material and methods. The study was performed in Ivanovo regional hospital for war veterans. 48 patients with long-standing KJ injuries were examined. All persons were divided into two groups: 1) with meniscus injury, 2) with anterior cruciate ligament injury (ACL). Average age of the patients was amounting to 28,1 ± 3,4 and 32,0 ± 2,81 years respectively. 18 persons without knee injuries were examined as the control group. Walking parameters were registered by «Stedis-Step» system for walking assessment with biofeedback («Neurosoft» Ltd., Ivanovo). Results and discussion. The increase in the average period of support (AS), period of double support (DS), reduction of average indicators of the period of transfer and single support (SS) was registered in both groups in comparison with control group; and the difference of the defined time parameters (asymmetry) between extremities (injured and “healthy”) in patients in the groups were statistically higher than in the control group. Despite the difference in injuries functional changes were of the same type, they reflected the mechanisms of unloading of the damaged limb. Firstly it refers to the duration of a single support (maximal load in walking in a step cycle) − SS decrease on the sick side was accompanied by compensatory increase of DS duration. Conclusion. Changes of time features of walking were of the same type in long-standing KJ injuries both in ASL injuries and in meniscus injuries and it reflected general for such injuries arising adaptive mechanism of unloading of the damaged limb by increasing the support period by increasing DS time.
