The study was a retrospective analysis of clinical and radiographic outcomes in a series of revision total knee arthroplasties performed with a constrained condylar knee prosthesis and press-fit modular stems. We hypothesized that the clinical and radiographic outcome of surface cementation would be inferior to that of metaphyseal cementation. Fifty-two consecutive revision cases were followed for a median of 8.2 years (range, 6 to 10 years).

Six out of the 53 revisions performed with the LCCK system were lost to follow-up. The final sample comprised 47 TKAs (23 right knees and 24 left knees in 47 patients). Mean age was 73 years (59 to 85 years), and 40 patients were women. The indication for revision was aseptic loosening in 31, deep infection in 10, ligament instability in 4, fracture in 1, and implant failure in 1 (Table ). Average preoperative and postoperative flexion, extension, ranges of motion, and knee and functional score according to the Knee Society system are shown in Table . The preoperative range of movement and Knee Society scores were worse in septic cases

Standing anteroposterior radiographs including the femoral head and ankle, as well as supine, lateral, and skyline radiographs of the patella, were obtained under fluoroscopic guidance. An independent observer, who was not involved in the procedure, assessed the radiographs for the alignment of the limb, the position of the components, and the presence and location of all radiolucent lines at the cement–bone interface (Figure ), according to the recommendations of the Knee Society [].

Total knee replacement, or total knee arthroplasty, is a surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses) ().A normal knee functions as a hinge joint between the upper leg bone (femur) and the lower
A total knee replacement replaces your diseased knee joint with man-made components, eliminating the damaged bearing surfaces that are causing pain. A diag

Total knee arthroplasty: Techniques and results - BCMJ

The increasing number of revision knee arthroplasty result in the more frequently use of a constraint implant but results from previous reports are difficult to interpret. The purpose of this study was to compare the long-term outcomes of superficial cemented versus metaphyseal cemented in revision total knee arthroplasty with a condylar constrained arthroplasty.

The first reliable TKA was Insall’s total condylar prosthesis in 1976 , which was an all cemented prosthesis

Answer:
C. An example of a hemiarthroplasty would be replacement the ball of the humerus, but not the shoulder socket. A unicompartment joint replacement would involve one part of the joint, such as the medial compartment of the knee.

Substantial improvements in range of motion and Knee Society score were achieved in all patients, although these were not significant between groups. Significantly more radiolucent lines were visible on the tibial component with surface cementation than with metaphyseal cementation, although the clinical differences were not relevant.
