Revision total knee arthroplasty (TKA) often requires long diaphyseal supporting stems. Pain at the end of the cemented revision stem has been reported, but no study has been published regarding the incidence in cementless revision TKA. This study reviewed 120 cementless revision TKAs with a diaphyseal slotted stem to compare the incidence of stem pain to that in a control cohort of 100 primary TKA patients with a metaphyseal stem. In the revision cohort, 20 out of 120 patients reported pain at… 
Modified hybrid cementing technique reduces stem tip pain and improves patient’s satisfaction after revision total knee arthroplasty
TLDR
The modified hybrid cementing technique for fixation of long-stem in revision TKAs reduced the end-of-stem tip pain in the shin, leading to significantly higher satisfaction compared with the hybrid cemented technique after revision TKA.
Is There a Difference between Cemented and Uncemented Femoral Stem Extensions in Revision Knee Arthroplasty?
TLDR
A large multicenter study will be needed to determine the optimal method of fixation of the femoral stem in revision TKA after a clinical and radiographic evaluation of 84 knee revisions in which a femoral component stem extension was implanted.
Comparing Revision Total Knee Arthroplasty Stems at a High-Volume Revision Center
TLDR
Hybrid and fully cemented rTKA techniques have similar survival rates at a minimum followup of 2 years and did not observe differences in LOS or change in hemoglobin suggesting early postoperative complications may not differ between cemented and hybrid stemmed groups.
Bone Defects in Revision Total Knee Arthroplasty and Management
TLDR
The overall outcome of RTKA is not as satisfactory as for primary TKA due to the uncertainty regarding the actual success rate and the risk factors for failure.
No Difference in Implant Micromotion Between Hybrid Fixation and Fully Cemented Revision Total Knee Arthroplasty: A Randomized Controlled Trial with Radiostereometric Analysis of Patients with Mild-to-Moderate Bone Loss.
TLDR
At 24 months after revision TKAs, cemented and hybrid-fixation replacements were equally stable and whether these findings indicate the possibility of loosening with longer follow-up remains to be investigated.
The Proximal and Distal Femoral Canal Geometry Influences Cementless Stem Anchorage and Revision Hip and Knee Implant Stability.
TLDR
In the investigated osseous defect model, the stem design (conical vs cylindrical), not the geometry of the femoral canal (proximal vs distal), was decisive regarding the circumferential anchorage length.
A shortened uncemented stem offers comparable positioning and increased metaphyseal fill compared to a standard uncemented stem
TLDR
It is suggested that shortened stems could provide adequate metaphyseal fixation and correct alignment and further studies remain necessary to evaluate how shortened stems perform in terms of osseointegration, clinical outcomes and survival.
