People with a limb loss at the level of the hip or pelvis have the most difficulty returning to walking compared with those with a lower amputation. This is because their prosthesis must replace the h...
The purpose of this study was to investigate the clinical and radiographic outcomes and to determine the survivorship of a high-flexion design total knee arthroplasty (TKA) prosthesis, the LOSPA knee ...
The study included 386 patients (503 TKAs) who were treated with TKA from 2011 to 2013 (follow-up period 10-12 years).The patients were assessed clinically using range of motion (ROM) of the knee, the...
Mean ROM improved significantly from the preoperative baseline of 117.3° to 126.5° at the final follow-up (p < 0.001). The mean KSS and WOMAC scores also both showed significant improvement after surg...
The LOSPA knee system, a high-flexion design total knee prosthesis, showed excellent long-term survivorship and improvements in clinical outcomes at 10- to 12-year follow-up....
There is no consensus on the importance of the kinematics of the prosthetic joint for the clinical outcome after total knee arthroplasty. A 3-armed randomized controlled trial was done to determine an...
Thirty-nine patients with a well-functioning total knee arthroplasty one year postoperatively underwent kinematic analysis of a weight-bearing step-up movement under fluoroscopic recording. Model-base...
The cruciate-retaining and anterior-stabilized groups' medial and lateral contact-points displayed similar paradoxical posterior translations during step-up in the magnitude of 7 and 2 mm, respectivel...
The cruciate-retaining and anterior-stabilized designs displayed similar contact-point translation patterns during a step-up movement. Only the posterior-stabilized design showed a pattern comparable ...
The purpose of this historical review is to highlight the progression and development of prosthetic reconstruction with a focus on the modular distal femur with hinged total knee arthroplasty....
Scientific literature was searched for descriptions of endoprosthetic reconstruction of the extremities to provide a thorough overview of the subject, focusing the research on the evolution of limb sa...
After the first works of Gluck and Giordano, with ivory and metal and the pioneer shoulder prosthesis by Pean in the late 1890s, a great advancement was brought by reconstructions performed for injure...
Walldius in the 1950s developed a fully constrained hinge knee, offering for the first time a consistent and replicable method of substituting the joint. In 1953, Shiers' prosthesis allowed for good f...
The study of the materials and mechanical solutions that was brought to the modern distal femur resection prosthesis is a good example of a virtuous multidisciplinary teamwork between orthopaedic surg...
Voice prosthesis leakage significantly affects the quality of life of patients undergoing laryngectomy, causing insecurity and frequent unplanned hospital visits and costs. In this study, the concept ...
Retrospective cohort study....
Tertiary hospital....
This study included all patients who underwent laryngectomy between 2000 and 2012 in the Netherlands Cancer Institute. Device lifetimes and voice prosthesis replacements of a retrospective cohort were...
Patients used a median 3.4 voice prostheses per year (range, 0.1-48.1). We found high inter- and intrapatient variability in device lifetime. When prophylactic replacement is applied, this would becom...
Based on our simulations, prophylactic replacement of voice prostheses is not feasible due to high inter- and intrapatient variation in device lifetime....
Personalizing prosthesis control is often structured as human-in-the-loop optimization. However, gait performance is influenced by both human control and intelligent prosthesis control. Hence, we need...
A reinforcement learning algorithm was used to achieve prosthesis control to meet normative knee kinematics in walking. A visual FB system cued the user to control prosthesis-side stance time to facil...
(1) Human control of gait timing reduced the tuning duration in individuals without amputation, but not for individuals with TFA. (2) The change of prosthesis control did not influence users' ability ...
The study provides novel insights on human-prosthesis interaction when cooperating in walking, which may guide the future successful adoption of this paradigm in prosthesis control personalization or ...
Long-term prognosis of complicated traumatic injuries depends on precise treatment planning. Establishing a balance between a patient's age, prognosis, financial hurdles, and treatment needs is challe...
A novel powered ankle-foot prosthesis is designed. The effect of wearing the novel prosthesis and an energy-storage-and-return (ESAR) foot on lower-limb biomechanics is investigated to preliminarily e...
The literature comparing bone-anchored prosthesis (BAP) with socket prosthesis (SP) consistently reports improvement in physical health and quality of life using primarily patient-reported outcome mea...
To determine the differences in mobility and balance using performance-based outcome measures and PROMs in people with transfemoral amputations (TFAs) fitted with BAP vs. SP....
Causal comparative....
Two groups of people with TFAs were recruited: one using a BAP (N = 11; mean age ± standard deviation, 44 ± 14.9 years; mean residual limb length as a percentage of the intact femur, 68% ± 15.9) and a...
There were no statistically significant differences between the BAP and SP groups in temporal spatial gait parameters and prosthetic mobility as measured by the 10-meter walk test and component timed-...
This study found that people with TFA who use a BAP can demonstrate similar temporal spatial gait parameters and prosthetic mobility, as well as self-perceived balance confidence and prosthetic mobili...
Erectile dysfunction can cause self-withdrawal and decreased quality of life. Patients who do not respond to pharmacological therapy and other conservative treatments are urged to undergo penile prost...
This meta-analysis followed Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) protocols. Five eligible studies were included from Pubmed, Scopus, ScienceDirect, and SemanticSc...
In this study, patient and partner satisfaction are significantly better (OR 3.39, 95% CI 1.66-6.93, p = 0.0008) (OR 2.32, 95% CI 1.75-3.08, p < 0.00001). Mechanical failure is also significantly high...
This study concluded that inflatable penile prosthesis is better in terms of patient and partner satisfaction, but mechanical failures occur more frequently in this type of prosthesis....
