“…Many types of prosthesis have been used for knee arthroplasty. The evolution of knee arthroplasty involves repeated cycles of failure and development for almost 40 years (Song et al, 2013). During the early stages from 1970 to 1974, instruments of the unicondylar, duocondylar, or hinged types were used, but these were eventually abandoned due to low success rates.…”

“…However, the femoral resection required to make a femoral housing can become a problem for smaller knees. From a biomechanical perspective, neither PCL preservation nor substitution designs can totally replace the biomechanics of the normal knee joint (Song, Seon, Moon and Ji-Hyoun, 2013).…”

“…Patients may experience suboptimal functional outcomes in TKA, with a previous study reporting that <25% of patients were satisfied with their ability to squat or kneel (Song, Seon, Moon and Ji-Hyoun, 2013). This dissatisfaction may be explained by the abnormal kinematics affecting the muscle movement arms and proprioceptive instability with removal of the ACL in TKA.…”

Computational models have been widely used for more than four decades to evaluate the mechanical behavior of knee joint arthroplasty. Validated computational models provide a virtual platform to develop optimal articular surfaces which achieve desired implant characteristics. This review paper provides a comprehensive overview of the computational models available to represent knee joint arthroplasty. A brief overview of knee joint anatomy and arthroplasty is provided, followed by computational model development techniques. Use of the computational models in development of knee joint arthroplasty and pre-or post-clinical evaluation is summarized. This review paper presents current modeling capabilities for implant design and stability, with further suggestions for studying the performance of implants on a population level. However, simulations must include closely corroborated multi-domain analysis in order to account for real-life variability.

“…Many types of prostheses have been used for TKA and TKR during the last 40 years, e.g., fixed or mobile knee prostheses, a total or unicondylar femoral component, cemented or cementless, etc. [ 2 ]. Anyway, this operation remains one of the most expensive prosthetic surgeries, constituting a significant burden for healthcare systems [ 3 ].…”

Wear Behavior Characterization of Hydrogels Constructs for Cartilage Tissue Replacement

This paper aims to characterize the wear behavior of hydrogel constructs designed for human articular cartilage replacement. To this purpose, poly (ethylene glycol) diacrylate (PEGDA) 10% w/v and gellan gum (GG) 1.5% w/v were used to reproduce the superior (SUP) cartilage layer and PEGDA 15% w/v and GG 1.5% w/v were used to reproduce the deep (DEEP) cartilage layer, with or without graphene oxide (GO). These materials (SUP and DEEP) were analyzed alone and in combination to mimic the zonal architecture of human articular cartilage. The developed constructs were tested using a four-station displacement control knee joint simulator under bovine calf serum. Roughness and micro-computer tomography (µ-CT) measurements evidenced that the hydrogels with 10% w/v of PEGDA showed a worse behavior both in terms of roughness increase and loss of uniformly distributed density than 15% w/v of PEGDA. The simultaneous presence of GO and 15% w/v PEGDA contributed to keeping the hydrogel construct’s characteristics. The Raman spectra of the control samples showed the presence of unreacted C=C bonds in all the hydrogels. The degree of crosslinking increased along the series SUP < DEEP + SUP < DEEP without GO. The Raman spectra of the tested hydrogels showed the loss of diacrylate groups in all the samples, due to the washout of unreacted PEGDA in bovine calf serum aqueous environment. The loss decreased along the series SUP > DEEP + SUP > DEEP, further confirming that the degree of photo-crosslinking of the starting materials plays a key role in determining their wear behavior. μ-CT and Raman spectroscopy proved to be suitable techniques to characterize the structure and composition of hydrogels.

“…Although the design of knee implants and the surgical techniques have evolved tremendously [13], there is still a failure rate of 60.2% during the first five years after which a revision surgery is needed, increasing the economic impact even more [14], [15]. Besides infection, the two major reasons for failure are aseptic loosening of the components, accounting for 31.2% of all failures, and instability, accounting for 18.7% of all failures [14].…”

Abstract-This paper presents the design and implementation of a new control strategy for Ghent University, Ghent, Belgium (UGent) knee rig, which is capable of imposing bicycle motions on cadaver knee specimens in order to investigate knee biomechanics and the impact of newly designed knee implants. An electromechanical description of the system with its instrumentation and limitations is given. Via system identification, a dynamical model of the multipleinput/multiple-output system is obtained on which the control strategy design is based. This control strategy combines position control and force control. Dynamical analysis of the system suggests the need for a Proportional-IntegralDerivative (PID) control strategy with gain adaptation. In order to fulfill the performance specifications, a feed-forward action and decouplers are added to the control strategy, and their advantages are shown via simulations and experiments. The complete strategy is implemented on the real system and the output signals are measured for analysis. The results indicate that the identified model fits well to the measured data and that the designed control strategy is able to accurately control the system. The measurements show that the predefined performance specifications have been achieved for a bicycle motion with a period of 10 s; the error on the position is smaller than 2 mm and the error on the force is smaller than 10 N.
