Kinematic and Kinetic analysis of Lower Limb Before and After Total Knee Arthroplasty (TKA) in a Chinese Population
No full textTo acquire a better understanding of how individuals adapt to knee osteoarthritis (KOA) and assess the effect of TKA, 3D gait analysis was conducted 17 pre-TKA KOA patients, 10 post-TKA KOA patients and 12 age-matched control subjects. Principle component analysis was used to extract waveform characteristics. Improved function was observed after TKA, but the overall lower limb capacity of post-TKA patients at 4 month post-surgery was still far below that of the control subjects. Post-TKA patients were characterized by reduced knee flexion, delayed joint motion and more gentle moments and ground reaction curves compared to controls.Nature Science Foundation of China [51275267]CPCI-S(ISTP)1701-170

Muscle loaded stability reflects ligament-based stability in TKA: a cadaveric study
No full textPurpose This paper aims at evaluating the effects of muscle load on knee kinematics and stability after TKA and second at evaluating the effect of TKA surgery on knee kinematics and stability; and third, at correlating the stability in passive conditions and the stability in active, muscle loaded conditions. Methods Fourteen fresh frozen cadaveric knee specimens were tested under passive and active condition with and without external loads involving a varus/valgus and internal/external rotational torque before and after TKA surgery using two in-house developed and previously validated test setups. Results Introduction of muscle force resulted in increased valgus (0.98 degrees) and internal rotation of the femur (4.64 degrees). TKA surgery also affected the neutral path kinematics, resulting in more varus (1.25 degrees) and external rotation of the femur (5.22 degrees). All laxities were significantly reduced by the introduction of the muscle load and after implantation of the TKA. The presence of the implant significantly affects the active varus/valgus laxity. This contrasts with the rotational laxity, in which case the passive laxity is the main determinant for the active laxity. For the varus/valgus laxity, the passive laxity is also a significant predictor of the active laxity. Conclusion Knee stability is clearly affected by the presence of muscle load. This points to the relevance of appropriate rehabilitation with focus on avoiding muscular atrophy. At the same time, the functional, muscle loaded stability strongly relates to the passive, ligament-based stability. It remains therefore important to assess knee stability at the time of surgery, since the passive laxity is the only predictor for functional stability in the operating theatre.The institution (department of orthopaedics, University hospital Ghent) has received funding from Smith and Nephew (research grant).

Kata Kunci : Komunikasi Dakwah Da’I Dalam Pembentukan Karakter
Mad’u. ABSTRACT
Communication is the most important part of everyday life.
Communication has several forms, including intrapersonal
communication, interpersonal communication, group communication
and mass communication. It is necessary to realize that the role of
communication is very important in social life, even in teaching and
learning activities.
The direct and indirect communication patterns used by Da'I
(Religious Teachers) in character building towards Mad'u (Students)
are very important communications in conveying their messages to
these students. There are many phenomena that occur in the Al�Qur'an Kindergarten regarding children thinking and behaving
differently from what is taught by their teachers. That the goal of
teachers in teaching and learning activities is to be able to educate
and improve the quality of their students. So this is a problem in the
communication process conveyed by teachers to their students. As a
Da'I who conveys Islamic teachings, the problem formulation used is
(1) How does Da'I (teacher) preach communication in forming the
character of Mad'u (students) at TKA/TPA BABUL JANNAH
Jagabaya III, Bandar Lampung? (2) The communication process of
Da'I (teacher) preaching in forming the character of Mad'u (student)
at TKA/TPA BABUL JANNAH Jagabaya III, Bandar Lampung? (3)
The effectiveness of da'wah communication carried out by Da'I
(teachers) in forming the character of Mad'u (students) at TKA/TPA
BABUL JANNAH Jagabaya III, Bandar Lampung?
The objectives of this research include, (1) To find out how
Da'I (teacher) preaching communication in forming the character of
Mad'u (students) at TKA/TPA BABUL JANNAH Jagabaya III, Bandar
Lampung. (2) To find out the communication process of Da'I (teacher)
preaching in forming the character of Mad'u (student) at TKA/TPA
BABUL JANNAH Jagabaya III, Bandar Lampung. (3) To determine
the effectiveness of da'wah communication carried out by Da'I
(teachers) in forming the character of Mad'u (students) at TKA/TPA
BABUL JANNAH Jagabaya III, Bandar Lampung. This research is
field research(field research) it is descriptive qualitative, namely
research carried out systematically by taking what is in the field. The data collection methods that the author uses are interview methods,
observation methods, and documentation methods for data analysis.
The author uses qualitative analysis.
From the results of research conducted, the da'wah
communication used by Da'I (Teachers) in developing children's
character at TKA/TPA Babul Jannah is two-way communication. This
indication is seen from the teacher conveying it to the students and
listening carefully to the message conveyed by the teacher. In this
case, feedback arises from students. In the implementation of the
delivery there is an effective communication pattern, this can be seen
from a teacher who has prepared a learning activity plan in
accordance with the goals that a teacher (Da'i) wants to achieve for
his students (Mad'u).
From the research results it can be concluded that the da'wah
communication used by Da'I (Teachers) in developing the character of
Mad'u (Students), has been created well and effectively because it can
be seen from the level of discipline and responsibility of those who
have implemented good character in surrounding environment. And it
is also supported by activities that support character development.

Functional alignment in robotic-assisted total knee arthroplasty: a systematic review.
No full textThe present study systematically reviewed current evidence on functional alignment (FA) in robotic total knee arthroplasty (TKA), discussing advantages and limitations, possible pitfalls, and prospects. This study was conducted according to the 2020 PRISMA statement. In August 2023, the following databases were accessed: PubMed, Web of Science, Google Scholar, and Embase with no additional filters or time constraints. All the clinical studies investigating functional alignment in robotic TKA were accessed. Only studies published in peer-reviewed journals were considered. The risk of bias was evaluated following the guidelines in the Cochrane Handbook for Systematic Reviews of Interventions. Non-randomized controlled trials (non-RCTs) were evaluated using the Risk of Bias in Nonrandomised Studies of Interventions (NRSI) (ROBINS-I) tool. Data from 1198 patients (seven studies) were retrieved. The mean length of the follow-up was 17.1 ± 6.4 months. The mean age was 67.2 ± 5.4 years, and the mean BMI was 30.9 ± 2.7 kg/m . FA might improve resection accuracy, implant alignment, and gap balancing in TKA, and additional high-quality clinical trials are necessary to properly establish the superiority of FA to other alignment techniques in TKA. Long-term clinical trials are needed to investigate the impact of FA on implant survivorship. Level IV, systematic review and meta-analysis. [Abstract copyright: © 2024.

Elucidation of the association between additional distal femoral resection and extension angle improvement following the actual surgical steps with the Robot-TKA system
No full textBackground: This study investigates the association between additional distal femoral resection and improved flexion contracture in total knee arthroplasty (TKA) with a robot-assisted system. Flexion contracture is a common issue in patients with knee osteoarthritis, which causes postoperative complications and functional limitations. This study aims to evaluate the effectiveness of additional bone resection in flexion contracture correction and knee extension angle improvement after the actual surgical steps. Methods: The study included 11 patients who underwent posterior-stabilized (PS)-type TKA with a robot-assisted system. The surgical technique consisted of precise bone resection and range of motion evaluation using a navigation system. A precut technique was used to facilitate posterior access and remove osteophytes that cause the contracture. The amount of additional distal femoral resection was determined based on the thickness of the insert trial required for achieving full extension. Results: The flexion contracture correction angle and the amount of additional distal femoral resection demonstrated a linear relationship. An average of 2.0 degrees with the standard error (SE) of 0.6 degrees improvement in flexion contracture was observed per 1.0 mm of additional bone resection. The postoperative evaluation demonstrated a significant improvement in knee extension angle, thereby reducing the contracture degree. Conclusion: This study was the first to perform the additional distal femoral resection on the living knee, which closely replicates the actual surgical steps. The current study revealed that an additional 1.0 mm of distal femoral resection in PS-type TKA improves knee extension angle by 2.0 degrees (SE 0.6 degrees) within an additional resection range of 1.0 mm to 3.3 mm.

Total knee arthroplasty improves gait adaptability in osteoarthritis patients; a pilot study
No full textBackground: Gait adaptability is of utmost importance for keeping balance during gait in patients with knee osteoarthritis, also after total knee arthroplasty (TKA). The aims of this explorative study are: (1) assess the effect of age, knee osteoarthritis and TKA on gait adaptability; (2) assess changes in gait adaptability pre-to post-TKA and (3) their relation to functional outcomes. Methods: Gait adaptability was measured using a Target Stepping Test (TST) in knee osteoarthritis patients before (preTKA) and 12 months after TKA (postTKA) and compared to asymptomatic old (AsOld) and young adults (AsYng). TST imposed an asymmetrical gait pattern with projected stepping targets at high walking speed. Gait adaptability was determined through stepping accuracy on the targets. The Oxford Knee Score (OKS) and Timed-Up-and-Go test (TUG) measured patients’ physical function. Results: 12 preTKA, 8 postTKA, 18 AsYng, 21 AsOld were tested. Age showed no effect on TST-stepping accuracy. PreTKA showed worse TST-stepping accuracy compared to AsYng and AsOld (7.7; 6.2 cm difference). PostTKA showed an improvement of 52% in TST-stepping accuracy compared to preTKA (3.2 cm). Higher stepping accuracy preTKA predicted higher stepping accuracy post-TKA. In addition, low preTKA stepping accuracy predicted more improvement postTKA. Pre-to post-TKA improvement of stepping accuracy was related to improvement on the TUG (Beta = 0.17, p = 0.024), but not to OKS. Conclusions: Gait adaptability is improved following TKA in knee osteoarthritis patients and no longer significantly worse than asymptomatic adults. The relation of gait adaptability to function is shown by its relation to the TUG and shows to have predictive value pre-to post-TKA.Biomechatronics & Human-Machine Contro
Loss of Tibial Bone Density in Patients with Rotating- or Fixed-platform TKA
No full textLittle is known about tibial bone remodeling with TKA and its clinical relevance. We performed a randomized clinical trial to compare tibial bone density changes in cemented components with different bearing designs. Bone density changes were assessed using quantitative computed tomography (qCT)-assisted osteodensitometry. Twenty-eight rotating-platform and 26 fixed-platform cemented TKAs were included. The nonoperated contralateral side was used as a control. CT scans were performed postoperatively and 1 year and 2 years after the index operation. Cancellous bone density loss (up to 12.6% at 2 years) was observed in all proximal tibial regions in both cohorts. In contrast, we found lower cortical bone density loss (up to 3.6% at 2 years). We found no differences in bone loss between fixed- and rotating-platform implants. The decrease of cancellous bone density after TKA suggests stress transfer to the cortical bone.

CSRP-TKAにおける術後屈曲可動域に対する影響について
No full textBackground: Various factors affect the improvement of range of motion (ROM) after total knee arthroplasty (TKA). However, there are few reports specific to cruciate-sacrificing rotating platform (CSRP) TKA. In this study, factors affecting postoperative ROM improvement of CSRP TKA were investigated. Methods: The study included 79 patients with knee osteoarthritis who underwent unilateral CSRP TKA at our institution. The group with an improvement of 5° or more (Δflexion angle) than the preoperative was defined as the good Δflexion group (38 knees), and that with less than 5° was defined as the poor Δflexion group (41 knees). The assessments were performed one day before and one year after surgery. Factors including rest and walking pain, knee flexion and extension angle, isometric knee extension strength, the five subscales of Knee injury and Osteoarthritis Outcome Score (KOOS), α, β, γ and δ angles, femoro-tibial angle (FTA), and condylar twist angle were assessed. Unpaired t-test, Mann-Whitney U test, and Chi-square test were used to test differences between the good and poor Δflexion groups. Multiple logistic regression examined the association between each factor and the dependent variables (good Δflexion or poor Δflexion). Results: Significant differences in the preoperative knee flexion, postoperative knee flexion, preoperative knee extension, and postoperative knee extension angles, postoperative KOOS pain and activity of daily living, β, ɤ angles were observed between the good and poor Δflexion groups. The model Chi-squared test revealed that the ɤ angle was significantly affected by the Δflexion angle. Conclusions: With the CSRP TKA, flexion insertion of the femoral component was associated with postoperative flexion ROM improvement.権利情報：© Copyright 2024. Matsuoka et al.
