Fixed-bearing versus mobile-bearing total knee arthroplasty: A prospective randomised, clinical and radiological study with mid-term results at 7 years

Functional outcome of PFC Sigma fixed and rotating-platform total knee arthroplasty. A prospective randomised controlled trial

“…the PFC Sigma total knee replacement system [12][13][14][15][16][17]. All of these studies, however, differ with regards to PCL status, implantation techniques (cemented or hybrid) and resurfacing of the patella (Table 3).…”

“…A further randomised controlled trial was carried out by Laedermann et al [16] including 90 patients with osteoarthritis who underwent a unilateral TKA. In all patients a posterior-stabilised implant was used and the patella resurfaced.…”

“…In recent years a number of studies have investigated the functional outcome of the PFC Sigma fixed-bearing and PFC Sigma rotating-platform total knee replacement systems [12][13][14][15][16][17]. Only three of these are randomised controlled trials [15][16][17].…”

“…Only three of these are randomised controlled trials [15][16][17]. In two of these studies [15,16] the patella was routinely resurfaced; in the third study the resurfacing status of the patella was not reported.…”

International Comparative Evaluation of Knee Replacement with Fixed or Mobile-Bearing Posterior-Stabilized Prostheses

“…It has also been argued that mobile bearings have the potential to enhance patellar tracking, reduce pain, enhance function, and reduce patellofemoral-related revision 8 . Many studies have compared clinical and radiographic outcomes of mobile and fixed-bearing total knee prostheses 4,5,7,[9][10][11][12] . One meta-analysis demonstrated an early reduction in anterior knee pain for patients with mobile-bearing total knee prostheses 7 .…”
