Hybrid Component Fixation in Total Knee Arthroplasty

Cemented versus cementless fixation in total knee arthroplasty

“…In a randomized controlled study, Gao et al (14), using RSA, found similar results in terms of migration, clinical outcomes, and survival rates of 41 TKAs in young patients (<60 years) undergoing knee replacement (NexGen, Zimmer, Warsaw, USA): 22 with fully cemented implants and 19 with hybrid fixated implants. Yang et al (18), following up 235 TKAs, performed with a hybrid fixation technique and using five different knee systems, reported a survival rate of 95% at ten years, and then of 92% at fifteen years. Cementation of the patellar component is crucial: it is now clear that cementless patellas are associated with a high risk of failure due to early loosening of the component.…”

Aseptic loosening of femoral components – A review of current and future trends in materials used

“…Thus, aseptic loosening of this component appears to be more challenging as it is involved with all three main leading causes. Clinical studies and follow-up investigations have provided evidence about TKR aseptic loosening including femoral component [9,[13][14][15]. The following sections explain about the main causes of aseptic loosening in details.…”

Effect of a single injection of tranexamic acid on blood loss after primary hybrid TKA

“…Recently, two studies that both had a minimum of 10 year follow-up [26,27] reported good clinical results with hybrid TKA, and suggested that the outcome after the hybrid procedure is comparable to the outcome after cemented TKA. We have also performed hybrid TKA (uncemented femur, cemented tibia) over a ten year period with a postoperative autologous blood reinfusion system …”
