“…Despite the effectiveness of total knee arthroplasty (TKA), [1][2][3] up to 20% of all patients report dissatisfaction in the postoperative period. [4][5][6] Dissatisfied patients often report receiving suboptimal quality of care, 7 which may negatively impact patient follow-up and long-term outcomes.…”

Does Age Influence How Patients Rate Their Experience of Care after Total Knee Arthroplasty?

The Centers for Medicare and Medicaid Services (CMS) have recently modified models for physician compensation with the use of patient administered surveys, such as the Press Ganey (PG). Currently, it is not well understood how the age of total knee arthroplasty (TKA) patients influences PG scores and hospital ratings. Therefore, we asked: (1) is there a difference in how patients rate PG survey elements between patients < 50 years of age, 50 to 80 years of age, and > 80 years of age and (2) what factors influence PG overall hospital rating in the various age groups? The PG database from our institution was queried from November 2009 to January 2015, yielding 728 patients who received a primary TKA. Patients were stratified by age at the time of surgery, based on those < 50 years (n = 43), 50 to 80 years (n = 639), and > 80 years of age (n = 46). The means for each domain was calculated and multiple regression analyses were performed separately for the three cohorts, to assess the influence (β-weight) of each domain on overall hospital ratings. Chi-square tests and Student's t-tests were performed appropriately to assess differences in categorical and continuous data between the three cohorts. No significant difference in mean scores was observed in any individual domain category between the three age groups. Communication with nurses had a significant influence on overall hospital rating in all three age groups. In addition, perception of pain demonstrated a significant influence on overall hospital rating for patients < 50 years of age (β = 0.807, p = 0.011) and those 50 to 80 years of age (β = 0.248, p = 0.014). For patients who were < 50 years of age, communication regarding medication had a significantly negative influence on overall hospital ratings (β = − 0.387, p = 0.025). For patients who were > 80 years of age, staff responsiveness (β = 0.403, p = 0.002) also significantly influenced overall hospital ratings. With physician reimbursement partially dependent on patient-reported experiences of care, orthopaedists must recognize and improve on the factors that affect patient satisfaction to avoid financial penalties. Although age was found to not have a global effect on PG scores after TKA, the factors that patients consider most important during their experience of care may vary by age group.

“…Thus far, there are no available interventions-5 treatments to restore degraded structures or decelerate disease development. During OA progression, the entire joint organ is affected, including cartilage, bone, synovial tissues, ligaments, and meniscus (37). In an advanced stage, TKA is considered as the most suggested surgical procedure to restore mechanical axes, correct alignment, and soft-tissue balance.…”

BackgroundEvery year, 3DP provides more alternatives and solutions in the medical field. Applications such as custom-made prosthetics and implants, platforms for pharmaceutical research, and PSAMs are the immediate emerging trends. Certainly, 3DP advancement is the convergence of multiple factors including improvements in medical software, 3D printer evolution, availability of new printing materials, improved industry support, and increasing commitment from medical societies and regulators. The overarching theme of this study is centered on exploring possible PSAMs and 3DP applications for improving surgical outcomes in orthopedics, particularly in ACL-R as well as providing functional models for TKA.Methods3-Matic, Rhinoceros, and SolidWorks were used to create three 3D computer-generated PSAMs: (1) Knee Joint model, wherein collagen fibers matrix structure is mimicked, (2) ACL-R model using a BPTB graft, incorporating key surgical outcomes such as orientations-architecture and positions-dimensions of the tunnels, as well as a custom-made SG based on patella anatomy (3) TKA model considering custom-made CS implants with symmetric tibial bearing design. Before printing, mechanical uni-axial tensile tests of materials were conducted using an Instron S3300, following the ASTM designation D412-C. The printing materials selection process and matching with anatomical structures were based on the analysis of the mechanical pattern of the strain-stress curves from different combinations of Agilus30™. The Stratasys J750™ printer was used to manufacture the ACL-R model (previous study), the ACL-R model with SG, and the TKA model. ResultsThe combinations No. 1-4 were chosen for 3DP with elastic modules of 1.8-0.7 MPa and Pearson coefficients of 0.980-0.991 respectively. The PSAMs were tested manually simulating 50 flexo-extension cycles without presenting ruptures, custom-made SG matches perfectly with PT anatomy. ConclusionFunctional PSAMs were printed with high fidelity, considerable cost, and short duration from planning to manufacturing. These coincided completely with 3D computer-generated PSAMs replicating fibers and features of the Knee Joint anatomy. The proposed PSAMs can be considered as an alternative to replacing cadaver specimens for medical training, pre-operative planning, education purposes, and validation of predictive models. We highlight the potential of PolyJet manufacturing combined with specialized medical software as a path to change the way specialists and researchers plan, execute, and validate complex procedures.

“…According to Liddle et al [4], 89 % of OA patients are present in the elderly or over 50 yr, while RA can be infected at all ages, but the most common are at age 40 yr and older in women [1,5]. In contrast to the damage to the OA, RA can affect the lining of the joints that causes painful swelling and can ultimately result in bone erosion and deformation of the joints, making it difficult to do the replacement with prostheses [1,6].…”

Total Hip Joint Replacement Surgery is the procedure of surgical removal of cartilage in the hip joints damaged by disease osteoarthritis to replaced with artificial components. Total Hip Joint Replacement has been indicated to relieve pain in the pelvis due to degenerative joint disease. In Indonesia, this procedure has been practised, but due to the cost of expensive products resulting in limited only to upper classify patients. The high prices caused by importing prostheses products, the technological capabilities and the difficulty to meet the standards of medical devices. The regulation of the Minister of Health of the Republic of Indonesia Number 52, 2016 for standard rates in organising health services Health Assurance Program, explained that the action of these operations entered into the insurance claims BPJS program, but not for the prostheses. This paper discusses the introduction of the development of the hip joint prostheses made from a local material that’s SS 316L, PEEK and Ceramic Dental Stone. The result of this development is the product of the hip joint prostheses has a reasonable price with good quality so that it can become affordable for middle to lower patients.
