“…Early studies on the outcomes of this implant have reported a high failure rate, particularly due to aseptic loosening. [86][87][88] Changes were made in the design of hinged implants to allow for a 20 degree of rotation of the tibial bearing around a yoke on the tibial platform. This resulted in a more congruent articulation and decreased wear and stress shielding.…”

Modes of Failure of Total Knee Arthroplasty: Registries and Realities

2014

Revision knee arthroplasty places a major strain on the health care system and is associated with high rates of complications, readmissions, and reoperations. Determining the modes of failure of total knee arthroplasty (TKA) preoperatively is essential for a successful revision procedure. Nationwide arthroplasty registries have served as reliable quality control instruments and as data sources of clinical studies that can potentially help guide the investigation of a failed TKA. Modes of failure vary according to the setting of the procedure (primary vs revision arthroplasty) and the prosthesis level of constraint. This article reviews the most prevalent modes of failure of primary and revision TKA, and further quantifies rates and specific modes of failure of bicruciate retaining, posterior cruciate retaining, posterior stabilizing, varus-valgus constrained, and hinged implants.

“…The poor results lead to several developments including a rotational axis that additionally allowed 20° of internal and external rotation. However, the outcomes of these second-generation implants remained disappointing [ 11 , 12 ]. Further enhancements, including a new design of the trochlear groove to improve patella tracking and patella kinematics, advancements in the stem design that facilitate osteointegration, improvement of biomaterials, and addition of second rotational axis to decrease torsional stresses on the bone implant interface, were introduced [ 8 , 13 – 15 ].…”

Background In the current study, we investigated midterm results of a new rotating hinge total knee arthroplasty (EnduRo prosthesis), which uses a new bearing material (CFR PEEK). Methods We prospectively analysed data of 50 patients with a minimum follow-up of 5 years. In 24 (48%) patients, a primary implantation was performed and 26 (52%) were revision cases. Clinical and radiographic examinations were performed preoperatively as well as postoperatively after 3 and 12 months and annually thereafter. The Knee Society Score (KSS), WOMAC, Oxford Knee Score (OKS), and range of motion (ROM) were used for clinical assessment. Results KSS, WOMAC, OKS, and ROM significantly improved between the preoperative and the follow-up investigations. The overall survival rate with revision for any reason as an endpoint was 77.9% after five years. The number of complications was significantly higher in the revision group (p = 0.003). Conclusion The EnduRo prosthesis provides highly satisfying clinical and functional results in severe primary as well as in revision cases. Implant-associated complications were rare. However, in cases of revision surgery, the risk for complications was considerably high, mostly related to previous joint infections and poor soft tissue quality.

“…This complication is present in all series and it also appears in ours. Kester et al [11] studied one type of device, which was removed because of implant loosening with pain, while two prostheses also produced a late infection. Radiographically, all the devices showed signs of progressive radiolucencies.…”

“…However, these models have been improved with modular designs and a wider availability of sizes and different rotational systems, thus reducing the risk of aseptic loosening. Older generations of rotating-hinge designs were associated with suboptimal outcomes [11,18,19], but there have been improvements in the design of these prostheses in recent years, the most important of which are the ability of the implant to rotate and the introduction of metal wedge augmentation and modular fluted stems with variable offset, which improve the alignment and allow press-fit fixation [5-8, 20, 21, 23].…”

Background Rotating-hinge total knee prostheses may be used for the treatment of global instability about the knee. The designs of previous generations were associated with suboptimal outcomes. Questions/purposes We evaluated the clinical and radiographic outcomes of salvage knee reconstructions using modern-generation, modular, kinematic rotating-hinge total knee prostheses. Methods We retrospectively reviewed 26 rotating-hinge arthroplasty devices to examine whether acceptable results were obtainable using a single arthroplasty design. The average age of the patients was 77 years (SD, 9 years); the minimum followup was 24 months (mean, 46 months; range, 24-107 months). The indication was revision surgery in 21 patients and complex primary surgery in five.
