Total knee arthroplasty in valgus knee deformities continues to be a challenge for a surgeon.
Approximately 10% of patients who undergo total knee arthroplasty have a valgus deformity …

Purpose Knee instability is considered one of the most frequent cause of failure after primary
total knee arthroplasty (TKA). In order to address intraoperative instability, varus-valgus …

Purpose Condylar constrained knee prostheses (CCK) are increasingly used in revision
total knee arthroplasty (rTKA), but the clinical effectiveness and long-term survival remain a …

Background Constrained condylar knee (CCK) prosthesis are common used for revision
surgery but can also help surgeons to improve implant stability in primary knee arthroplasty …

Background The purpose of this study was to evaluate (1) the reoperation rates and
survivorship for septic and aseptic causes,(2) radiographic outcomes, and (3) clinical …

Methods: We conducted a case-control study using prospectively collected data on
functional outcome scores and range of motion preoperatively and at 6 months and at 2 …

Background Prostheses with varus-valgus constraint (VVC) are increasingly utilized in
primary total knee arthroplasty (TKA) to address coronal malalignment and instability though …

Objectives: This study retrospectively investigated the mid-term outcome of Legacy
constrained condylar knee (LCCK) prosthesis in patients with rheumatoid arthritis (RA) …

Purpose The optimal degree of constraint of a total knee arthroplasty for treatment of knee
osteoarthritis with ligamentous laxity is under debate. While varus valgus constrained knees …

Introduction The rate of revision TKA and thus the use of hinged implants (HI) steadily rises.
Aseptic loosening lies on the top of the failure patterns. However, no evidence exists until …
