Can robotics lower the technical barriers to cementless TKA?

Cemented Total Knee Arthroplasty (TKA) fixation is considered less technically challenging than cementless TKA because it is more forgiving of small defects in the bone cuts, which can be filled with cement.1 “Arguably the principle cause of poor outcomes in...

In this analysis of 842,072 primary total knee replacements (TKR) implanted for osteoarthritis between 1st April 2003 and 31st December 2016, the patella was not resurfaced in 536,228 (64%) of the procedures and resurfaced in the remaining 305,844 (36%) of cases (1)....

Good reasons to consider day case knee arthroplasty

Good reasons to consider day case knee arthroplasty

Surgeons in several countries have shown increasing interest in outpatient surgery for selected patients. While the safety of standardised outpatient Total Knee Arthroplasty (TKA) and Total Hip Arthroplasty (THA) has been well documented, there are concerns that...

Promising 5-year results for personalized total knee prosthesis

Promising 5-year results for personalized total knee prosthesis

Knee pain continues to be one of the top five reasons for revision knee replacement. Adverse knee pain has been reported in 10 to 34% of all total knee arthroplasty (TKA). Up to 20% of those patients complain of more pain post-operatively than preoperatively.1 Tibial...

Which patients will benefit most from personalized alignment?

Which patients will benefit most from personalized alignment?

Deciding upon the optimal coronal alignment for total knee arthroplasty (TKA) remains an area of debate. Mechanical alignment (MA), resulting in a horizontal joint line and neutral mechanical axis, has long been considered the ‘gold standard’ in TKA, and has...

Is it time you revisited cementless total knee arthroplasty?

Is it time you revisited cementless total knee arthroplasty?

While initial designs and techniques of cementless TKR yielded unspectacular results and high early failure rates, subsequent improvements have led to more encouraging results, and implant survival of between 96% and 100% at 10 to 15-year follow-up.1 Furthermore,...

Implant-guided motion may help patients “forget” their TKR

Implant-guided motion may help patients “forget” their TKR

More patients in the MC group were “very satisfied” (92.6% Vs 81.5%; p = 0.04) and fewer were “not at all satisfied” (1.2% Vs 9.2%; p = 0.04) compared with the CR group1. Although the MC group reported better pain scores than the posterior stabilised (PS) group at...

Anatomic tibial tray demonstrates promising two-year RSA results

Anatomic tibial tray demonstrates promising two-year RSA results

Prosthetic migration measured by radiostereometric analysis (RSA) within the first 2 years of knee arthroplasty is predictive of long-term aseptic mechanical loosening.1 This makes it a good tool for evaluating the likely performance of new implant designs.1 In this...
