Article : The challenges of total knee arthroplasty in posttraumatic osteoarthritis: A cook book approach By Friedrich Boettner
Trauma can initiate the deterioration of cartilage inside the knee and result in end-stage osteoarthritis requiring a total knee arthroplasty. However, intra- and extraarticular deformities as result of trauma trigger osteoarthritis through different mechanisms and pose different challenges at the time of knee replacement surgery.
Article : Adjusted mechanical alignment to achieve a well-balanced knee with less soft tissue releases: Surgical tips and tricks for a modified “extension gap first technique” in TKA By Hagen Hommel (1,2), Peter Fennema (3)
In total knee arthroplasty (TKA), one of the primary goals has been a well-balanced stable knee with a neutrally aligned lower limb because this has been considered to be necessary for positive clinical outcomes and implant survivorship.
Article : Cup-cage reconstruction for severe acetabular bone loss and pelvic discontinuity By C. HIPFL(1), C. PERKA(1), G.I. WASSILEW(2)
The management of severe acetabular bone loss in revision total hip arthroplasty (THA) is technically demanding. In cases of major column defects with less than 50% host bone contact, adequate implant fixation with a hemispherical cup and screws alone is not feasible.
Article : A new approach for Paprosky 3 acetabular defects with patient matched 3D printed implants based on bone quality assessment By S.N van Laarhoven, M. Baauw, G.G van Hellemondt, M. Spruit
Major acetabular defects are most complex and difficult to reconstruct especially if pelvic dissociation is present. Many techniques have been proposed such as bone impaction grafting, structural allografts, anti-protrusio or reconstruction cages, tantalum augments and cup-cage reconstruction.
