The progression of gonarthrosis results in reduction of physical activity. One of the factors that increase the risk of osteoarthrosis may be joint overload related to the malalignment of the mechanical axis of the lower extremity. The medial compartment (MC) of the knee is particularly susceptible to overload due to the external knee adduction mom...

Abstract
Background:
Osteoarthritis (OA) is a leading cause of disability in the elderly population. Gait analysis is a widely used tool to measure functional outcomes after total knee arthroplasty (TKA). This study aimed to assess the gait pattern and influence of TKA in patients with osteoarthritic knees.
Materials and Methods:
Preoperative and postoperative gait analysis was carried out on patients with grade 4 OA knee undergoing TKA. Sequential 33 adults (45 knees) with a mean age of 68.4 ± 5.8 years were studied. Gait analysis was carried out in Jupiter gait lab with 9 Qualisys Oqus cameras system and Qualisys track manager. Kinematic data were processed using Visual 3D C-Motion Software during a minimum of 6 walks across the walkway.
Results:
A significant difference in temporospatial parameters (gait speed, Cadence, step time, step length, stride width, stride length), joint kinematics in the sagittal plane (pelvis, hip, knee, ankle), coronal plane (pelvis, hip, knee, ankle), transverse plane (hip, knee) and motion analysis profile of knee (flexion/extension), ankle (dorsiflexion/plantarflexion), and hip (adduction/abduction). A significant difference was observed in the oxford knee score (OKS), Short Form 12, and knee society score.
Conclusion:
3D gait analysis is a good tool to document and compare gait changes in patients undergoing TKA. Recent advances in surgical techniques and improvements in prosthesis design are important factors for better functional outcomes. Our results may be used by clinicians, physiotherapists, or researchers as a reference for integrated aspects for the development of TKA implant designs and improving functional outcomes.

Purpose: The aim of this study was to establish the reference values of: spatiotemporal parameters, joint angles, ground reaction forces and plantar pressure distribution collected simultaneously on the same measurement path during normal gait in a homogenous group of young, healthy women. Methods: The studied group consisted of 28 healthy women aged 21 years on average. The motion capture system BTS Smart-D, 2 AMTI force platforms and Footscan pedobarographic
platform were used in this research. The 14-metre measurement path and the 6-metre distance that examined women had to walk through before entering the measurement area ensured that a natural gait pattern was recorded. Statistical analysis was performed to evaluate differences between right and left lower extremities. Results: The applied methodology enabled collecting several parameters regarding normal female gait biomechanics such as: spatiotemporal parameters, angle-time characteristics as well as range of motion of pelvis, hip, knee and ankle joints in gait cycle, force-time characteristics and peaks of ground reaction force components in stance phase, peak pressure and time of loading of defined foot regions in stance phase. Conclusions: The results may be used by clinicians, physiotherapists or researchers as a reference in diagnosing gait disorders or evaluating patient’s walking pattern. In actual literature there are some disparities in gait parameters reference values even regarding similar research groups. These differences may arise from distinct methodology, slower or faster gait,
other laboratory environment etc. This should be considered and more than one source of normative values should be checked when searching for reference data.
Background
This study employs 3D gait analysis to investigate normal gait patterns in individuals afflicted with knee Osteoarthritis (OA). Focusing on the adult osteoarthritic population, the research aims to establish reference values for joint angles, temporospatial parameters, Gait Profile Score (GPS), and Movement Analysis Profile (MAP) collected concurrently along a standardized walking path. Furthermore, the study delves into potential variations linked to gender and OA severity, comparing gait parameters between male and female participants and among individuals with grade 3 and grade 4 OA.
Method
The study involved 34 adults with a mean age of 68.6 ± 5.75 years, all experiencing OA knees and awaiting Total Knee Arthroplasty (TKA). Utilizing Qualisys Motion capture system, 3D gait analysis was conducted. Data were processed through Visual 3D C-Motion Software.
Results
Gait analysis revealed noteworthy differences between genders for various parameters, including stance time, GPS, MAP of the hip, and joint angle for the sagittal plane (ankle), coronal plane (knee), and transverse plane (hip and knee). Moreover, significant differences were observed between grade 3 and grade 4 OA knees in MAP and for the transverse plane joint angle (ankle).
Conclusion
This gait analysis study sheds light on distinctive gait patterns in the adult osteoarthritic population. The identified variations in temporospatial parameters, joint angles, GPS, and MAP provide valuable reference values for individuals suffering from knee OA. The observed differences between genders and across different OA severity grades emphasize the need for personalized approaches in managing knee OA and planning interventions like TKA.
Introduction :
Biomechanics plays a crucial function in osteoarthritis. Changes in the biomechanical parameters of the contralateral knee following total knee arthroplasty (TKA) may result in pain in the contralateral knee. The objective of this study was to examine preoperative and postoperative gait measurements on the contralateral leg following a TKA for a variety of gait measures at a self-selected normal gait pace in a similar speed population.
Method :
There were 11 patients included in the study, and their average age was 68 (7 females and 4 males). Gait analysis was performed at a sampling frequency of 120 Hz using nine cameras Qualisys motion capture systems (Qualisys AB, Sweden). To process the kinematic data, Visual 3D C-Motion Software was used.
Results :
Ankle plantar flexion (0.01), knee abduction during the terminal stance (0.002), and knee adduction during the initial swing (0.01) all showed a significant difference. In spatiotemporal data, walking speed (0.01), stance time (0.01), step length (0.005), and stride length (0.001) all showed significant differences. There were significant differences in knee flexion-extension (0.04) values.
Conclusion :
A change in the contralateral knee's biomechanics as a result of TKA is strongly suggested by significant alterations in the knee's stance phase, joint angle, and MAP. The research may help to modify the stride of the contralateral leg to decrease the advancement of osteoarthritis.
Background
Mechanical forces and joint misalignment are considered risk factors for the development of knee osteoarthritis (KOA). Early detection of KOA and distinction between lateral and medial compartment overloading (CO), might be important to inform appropriate preventative interventions. This study evaluated reliability and validity of a test battery consisting of ten clinical tests to predict knee CO.
Methods
Independent observers examined 30 participants with symptoms of KOA. Inter-rater reliability of the ten tests, as well as the anticipated CO based on the whole test battery, was determined. All participants received a SPECT-CT, which served as reference standard for CO. The agreement for CO between SPECT-CT and clinical examination was assessed to determine criterion validity.
Results
The Kappa coefficients (k) for the ten individual clinical tests ranged from 0.19 to 0.80. The k for determining CO was 0.52 (95% CI = 0.28 - 0.76). The agreement for CO between SPECT-CT and clinical examination (i.e. criterion validity) yielded a k of 0.26 (95% CI = -0.06 - 0.58). Logistic regression indicated that valgus alignment was strongly related with lateral CO. No other relationships were found between individual tests and CO.
Conclusion
Accurate measurement of frontal plane knee angle is important to determine CO. This particular test yielded good reliability, but low validity. Reliability of the nine remaining clinical tests was fair to moderate. Criterion validity of the clinical examination to predict CO was low. Therefore, this test battery in its current form cannot be used in practice to determine CO.
