Are Proud Tibial Cone Constructs an Effective Alternative to Those That are Fully Seated in Revision Total Knee Arthroplasty?

Background: This study compared the clinical, radiographic, and patient-reported outcomes between patients treated with the traditional fully seated tibial cone construct and those with the novel proud tibial cone construct in revision total knee arthroplasty (rTKA).

Methods: This was a retrospective study of 56 adult patients who had a minimum 2-year follow-up and underwent rTKA with either the fully seated (n = 18 knees) or proud (n = 42 knees) tibial cone construct between 2010 and 2020. The electronic medical record was reviewed for demographic, clinical, and radiographic data.

Superficial Femoral Artery Pseudoaneurysm After Intra-articular Adductor Canal Pain Catheter Placement for Total Knee Arthroplasty.

Vascular injury following total knee arthroplasty (TKA) is a rare complication. The authors present a case of superficial femoral artery aneurysm in a 60-year-old man following elective TKA in the setting of intra-articular On-Q* (Avanos Medical) pain catheter placement into the adductor canal for postoperative pain control. This is the second reported case of pseudoaneurysm secondary to adductor canal block.
