TM Rotaglide+ Total Knee System Product overview

Open the catalog to page 1

TM Rotaglide+ Originality | Stability | History Originally implanted in 1988, Rotaglide+ was the first total knee design to adopt a true mobile bearing philosophy. The implant features a rotating and translating tibial insert providing enhanced joint stability and minimal polyethylene wear. 2|

TM Rotaglide+ Originality The first true mobile bearing design, Rotaglide+ features spherical posterior femoral condyles and highly conforming tibial inserts. The insert mobility and high conformity allow the Rotaglide+ to maintain large contact areas throughout the range of motion, resulting in low volumetric wear rates and improved implant longevity. 180 160 Volume (mm3) 140 Fixed Mobile 120 100 Figure 1.

Inspired by motion Recent kinematic studies have suggested that the natural femur may pivot medially or laterally during gait and non-ambulatory activities2,3. The symmetrical design of the Rotaglide+ insert allows up to 5mm translation and ±20° rotation, accommodating varying centres of rotation about both the medial and lateral femoral condyles. Rotaglide bearing mobility allows selfalignment of the tibial insert in vivo which has been shown to reduce patellofemoral stresses4 and minimize anterior knee pain5. |5

TM Rotaglide+ Stability Featuring spherical posterior femoral condyles the Rotaglide+ allows for a single flexion-extension axis reducing mid-flexion instability and maintaining ligament isometry6,7. A posteriorly located centre of rotation lengthens the quadriceps moment arm, reducing quadriceps effort required post total knee arthroplasty and accelerating patient rehabilitation6,7. 6|

With the patient in mind A 10° posterior slope built into the distal femoral and tibial implant design allows for proximal bone conservation. The anatomic tibial slope directs forces through the tibial baseplate during heel-strike, minimising the risk of bearing dislocation. 10° 10° |7
