From: Outcomes of the rotating hinge knee in revision total knee arthroplasty with a median follow-up of 6.2 years

Revisions Failure Time to failure Treatment
1 Periprosthetic femoral fracture 6.2 years Osteosynthesis combined with exchange of the femoral component and the polyethylene insert
2 Aseptic loosening (femur) 7.2 years Exchange of the femoral component and the tibial insert
3 Prosthetic joint infection 0.17 years DAIR
4 Arthrofibrosis 5.8 years Open lysis of adhesions through medial parapatellar arthrotomy
5 Mechanical hinge-related complication (without trauma); fracture of the tibial cone and the anterior part of the femoral hinge-post 3.0 years Exchange of the tibial insert and the hinge mechanism
6 Patellar dislocation (traumatic) 0.2 years Secondary patellar resurfacing
7 Rupture of the quadriceps tendon and the MPFLa 5.1 years Knee arthrodesis
8–15 Prosthetic joint infection 9 days–8.7 years 2-stage revision arthroplasty
  1. a Patient had multiple complications, see Additional file 1
  2. MPFL The medial patellofemoral ligament
  3. DAIR Debridement and implant retention
