Introduction: In the society of the 21st century, osteoarthritis is considered one of the primary causes of the occurrence of pain and disability. Arthroplasty is the treatment of choice for advanced degenerative changes. The aim of the study was to carry out a functional assessment of patients at early stages of rehabilitation after total knee replacement.
Material and methods: The research material included 35 individuals qualified for the total knee replacement. The group consisted of 26 females with an average age of 68.6 ± 7.0 and 9 males with an average age of 70.8 ± 9.1. To assess their functional status, the following tools were used: 100-point Lysholm-Gillquist scale, the VAS scale, the Timed Up and Go test, the Lovett scale and the range of motion measurement made with a goniometer. The level of significance was set at p<0.05.
Results: The research revealed statistically significant differences in the measurements of active and passive ranges of flexion and active extension in the knee joint, knee flexors and extensors muscle strength, the VAS scale and the 100-point Lysholm-Gillquist scale.
Conclusions: 1 After applying the treatment in the form of a total knee replacement, the functional state of the patients improved at early stages of rehabilitation. 2 The study proved the effectiveness of treating advanced degenerative changes through total knee replacement and the patients’ functional improvement at early stages of rehabilitation.
This study evaluates changes in the knee following anterior cruciate ligament (ACL) injuries by presenting the kinematic characteristics of the ankle and hip joints and the pelvis, and assessing the dynamic forces applied by knee joint muscles under isokinetic conditions to identify compensatory mechanisms. Seventeen ACL-deficient males, 16-47 years of age, participated in the study, and measurements were taken an average of 24.4 months after their injuries occurred. Vicon, a three-dimensional motion analysis system, was used to examine the participants' locomotive characteristics. Isokinetic tests were carried out using Easytech Genu 3 at two velocities 60 and 180°/s. We found that deviations from normal gait were most common in the ACL-deficient knee, and that there was also a noticeable impact on the functioning of other joints in the same limb. However, even chronic knee joint laxity did not result in a considerable change in a participant's gait stereotype. Measurements showed a reduction in muscular strength in knee joint extensors and flexors in isokinetic contraction in the developed joint moments of the muscle groups under research compared with the healthy limb.
The aim of the study was the attempt to determine the specifics of injuries suffered by people who do snowboarding recreationally. On account of the low number of cases one should determine the work as descriptive study. Methods. The research material was a group of 40 persons aged 18-30 practicing snowboarding. The research tool was a questionnaire prepared by the research authors. Results and Conclusions. The most frequent type of injury suffered by the questioned snowboarders was contusion (67,5%) and dislocation (50%) of joints. Injuries concerned the upper limb mainly (injures of the wrist/palm-50% of all) and the basic form of physical therapy applied in the examined group was criotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
