Cementless Highly Porous Titanium Tibial Base Plate in Total Knee Arthroplasty – Midterm Outcomes.

Introduction & Aims
 TKA in more active and young patients has prompted the interest durable biological methods of Osteo-integration with cementless components. With emergence improved biomaterials like porous titanium success, search for a long-term durability survivorship may have ended. This is retrospective study 492 consecutive TKAs using Cementless tibial fixation, reporting on early 4 years clinical radiological outcomes.
 Method
 We studied performed consecutively by single surgeon between 1stJan. 2010 31stDec. 2015 cementless, fixed bearing tray (porous–Regenerex, Vanguard, Zimmer-Biomet) femoral component (Vanguard) no exclusion criteria. Clinical follow-up was done these addition comprehensive joint registry review whole cohort (Level II evidence).
 Results
 The average Knee Society Score at final 89.33, pre-op being 42.06. Average post-op WOMAC score 43.45 77.78. On examination, had osteolysis around base plate. In our series 9 were revised, out which only revised 5 patella resurfacing or liner exchange. Overall excellent 99.4% 5.9 based AOANJRR data.
 Conclusions
 fixation construct can provide stable bone ingrowth side predictable to year outcomes.
