 A video abstract is available with the new study by Hannon et al. in JBJS: 

 Cementless Versus Cemented Total Knee Arthroplasty: Concise Midterm Results of a Prospective Randomized Controlled Trial 

The investigators previously reported the 2-year results of a prospective randomized controlled trial of cementless vs. cemented total knee arthroplasty (TKA). The implants were of the same design. Those results can be found in the 2019 JBJS report by Nam et al. Of the 141 patients included in the original study, 127 were in the new analysis.  

 Play the video abstract:  

 As concluded by the authors, “At 6 years, there were no differences between cementless and cemented TKA implants of the same design in terms of survivorship, clinical, or radiographic outcomes.” 

 Access the study by Hannon et al. at JBJS.org.

  1. Well-done video but I must say it gave me information I could have read in half the time. Nice to see a good video, however!

  2. Probably a few caveats needs to be presented in this video (and the abstracts)
    1. The knee implants in involved (Stryker, Triathlon) are cruciate retaining only
    2. No Patella resurfacing is involved
    3. The average age of the study population is 63 years, which is distinctly younger than most national joint registries (Australia: 68.5, UK 69, Sweden 69, American AJRR 67), it is unknown if having younger patients may affect the cementless prosthesis performance in the study.
    4. The design differs significantly in my opinion particular with respect to tibial baseplate in keel design and additional pegs for cementless component, hence it is not simply comparing one design with cementless coating with one without. The idea this is a comparative study “between cementless and
    cemented TKA implants of the same design” is misleading to say the least.
