“…In our investigation no significant influence of tibial component rotation on patellofemoral kinematics could be found. Therefore, we cannot support the findings of Berger et al [12] and Figgie et al [23], who attached great importance to the tibial component rotation. Also Heinert et al [1] could not find any difference between mobilebearing and fixed-bearing tibial component in matters of patellar kinematics in their investigation using computer navigation.…”

“…Also Heinert et al [1] could not find any difference between mobilebearing and fixed-bearing tibial component in matters of patellar kinematics in their investigation using computer navigation. In a prospective randomised study, Pagnano et al [24] showed that a rotating platform knee design did not decrease the prevalence of lateral retinacular release, patellar tilt or subluxation in comparison to a posterior-stabilised, fixedbearing knee [23]. A few radiological studies ascribe altered patellofemoral kinematics and the appearance of anterior knee pain to combined femoral and tibial component internal rotation [2,5].…”

“…Patellofemoral failures have been noted in other investigations [3,24,28,32,33,46]. These failures have been associated with poorly designed metal-backed components, patellar complications such as fracture or subluxation, and more subtle problems such as patellar "clunk."…”

We retrospectively reviewed the experience of a large international multi-centre study of primary total knee arthroplasty with mobile bearing design and modifications of the tibial component to allow for bicruciate preservation, posterior cruciate retention, or sacrifice. Twenty-seven surgeons performed 4,743 total knee replacements between 1981 and 1997. Implants inserted were 324 that retained both cruciate ligaments, 2,165 that retained the posterior cruciate, and 2,254 that sacrificed both cruciates. The patella was resurfaced in 2,838 and unresurfaced in 1,905. With failure defined as revision or reoperation for any reason, the overall survivorship was 79% at 16 years' follow-up. Revision occurred in 259 (5.4%) knees out of the entire cohort. The risk adjusted rates of failure were higher in females, younger patients, osteoarthritis, posttraumatic arthritis, and in patients who had a meniscal bearing prosthesis or patellar resurfacing. The most common cause of revision was bearing-related issues including chronic instability, bearing subluxation, bearing dislocation, or bearing wear in 2.3%.Résumé Nous avons revu rétrospectivement une série multicentrique de prothèses totales primaires de genoux avec plateaux mobiles et pièce tibiale permettant le sacrifice ou la conservation d'un ou des deux ligaments croisés. Entre 1981Entre et 1997 prothèses ont été faite par 27 chirugiens. Les implants utilisés étaient pour 2254 sans ligaments croisés, pour 2165 avec croisé postérieur et pour 324 avec conservation des 2 croisés. La rotule a été resurfacée 2838 fois. Avec l'échec défini par la reprise chirurgicale, la survie était de 79% à 16 ans de recul. Une reprise a été faite 259 fois (5,4%). Le risque d'échec était plus grand chez les femmes, les patients jeunes, en cas d'arthrose primaire ou post traumatique et chez les patients avec une prothèse à ménisques mobiles ou avec une rotule prothèsée. Les causes les plus fréquentes de révision étaient l'instabilité chronique, la subluxation ou la luxation des plateaux mobiles et leur usure.

Two hundred and three patients with 219 Miller Galante type I knee arthroplasties have been reviewed in a multicentre study at an average of 3.5 years after operation. Three groups are compared: 83 patients were treated with a full polyethylene patellar component; 68 with a metal backed component, and 68 with patellar debridement without resurfacing. We found no differences between the 3 groups in relation to pain, range of movement, stability, flexion or extension deficit, extension lag, alignment, walking distance, ability to climb stairs or the use of walking aids. There was also no difference in the incidence of patellofemoral complications. The number of revision operations was the same in patellar-resurfaced and non-resurfaced knees. Lateral release was accompanied by more complications in every subgroup.
