2018年1月24日 · Based on the initial success of porous tantalum metaphyseal cones and acetabular components [29 – 34], there has been an explosion of investigation and development of alternative porous metal constructs, primarily using titanium rather than tantalum [35 – 38].

2017年3月29日 · Two different types of implants were used: 10 constrained condylar knee (CCK Zimmer) and 18 TC3 (DePuy Johnson & Johnson). All patients were over 75 years old (mean 81.75) with a severe deformity and clinical evaluations at 2-, 6-, …

Primary Cruciate-Substituting TKR incorporates a central polyethylene eminence in the tibial insert to perform the function of an absent PCL. The corresponding femoral compo-nent uses A/P cuts and chamfers identical to those of the PCL-retaining component, allowing ready transition without revision of the pre-pared implantation site. Revision TKR

2023年8月3日 · This study aims to retrospectively evaluate the clinical and radiological results of patients undergoing rTKA with press-fit condylar (PFC) Sigma TC3-mobile bearing system and porous metaphyseal sleeves in AORSI type II and III bone defects.

2015年1月1日 · The Sigma TC3 system has only a limited offset available in both the tibial and femoral components. It requires a relatively large femoral box cut and has shown increased risk of patella clunk. It has a symmetric tibial tray which is unpolished and uses one of the larger number of surgical instrument trays.

2020年4月16日 · TKR is an established treatment option in knee osteoarthritis, with excellent results and reproducibility (Meding et al. ). Issues begin to arise for the general orthopaedic surgeon when the affected knee has significant bone loss, extreme varus/valgus deformity, contractures or ligamentous instability (Baldini et al. [ 4 ]), rather than ...

A press-fit condylar Sigma TC3 Knee System (DePuy Synthes/Johnson & Johnson, Warsaw, IN) was implanted, consisting of a size-4 femoral component with a 31-mm sleeve and a 16 × 115-mm stem. The tibial component was a size-3 mobile bearing tibia with a 45-mm sleeve and a 14 × 75-mm stem (DePuy Synthes/Johnson & Johnson).

Aim: To assess the functional results of revision TKR with the PFC/TC3 system, and to correlate this with the reasons for revision and restoration of joint height. Method: 153 patients underwent revision TKR using the PFC/TC3 system.

2019年8月4日 · Addressing bone loss and securing implant fixation can be challenging in revision total knee arthroplasty (TKA). We present the results of a large series of revision TKAs using a metaphyseal sleeve.

Revision and Sigma TC3 RP inserts • Accepts rotating platform hinged insert from the Orthogenesis LPS™ (Limb Preservation System), which is compatible with the S-ROM® Noiles™ Rotating Hinge (NRH) femoral component and LPS femoral component • Cortical rim intact • Central or peripheral metaphysis loss
