Survival of Bicompartmental Knee Arthroplasty at 5 to 23 Years

Abstract

Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Patellofemoral arthroplasty, where are we today?

“…Some recent publications suggest that this option yields favourable long-term results and would thus extend indications for patellofemoral prosthesis, especially for young, active patients [54].…”

“…1 Intraoperative view of the anterior femoral cut of a secondgeneration patellofemoral prosthesis that completely replaces the anterior compartment of the knee medial or lateral tibiofemoral compartments [41]. To extend indications, some authors have proposed to combine the PFP with cartilage restoration procedures in cases of a defect in the load-bearing portions of the femoral condyles [39] or unicompartmental knee arthroplasty in cases of significant degenerative disease in an additional compartment [54]. Inflammatory joint disease remains an absolute contraindication because of global involvement of the knee joint.…”

Bicompartmental Versus Total Knee Arthroplasty for Medio-patellofemoral Osteoarthritis: A Comparison of Early Clinical and Functional Outcomes

“…2,10 However, little is known about how it fares when compared with a TKA, which is still the most commonly performed arthroplasty procedure for MPFOA. In a prospective cohort comparison of nonmodular BKA (Journey-Deuce implant, Smith and Nephew) and CR-TKA, Morrison et al 9 reported a complication rate of 28.6 and 6.1% (p ¼ 0.045) in the respective groups at short term.…”

“…Although TKA is a reliable solution for MPFOA, it might be too radical for a bicompartmental disease because it sacrifices the intact cruciate ligaments and resurfaces the healthy lateral compartment. 1,2 Alternatively, bicompartmental knee arthroplasty (BKA) can offer a conservative and kinematicspreserving solution to the problem. [1][2][3] Limited bone resection and preservation of the cruciate ligaments may result in greater stability, better knee flexion, more normal gait pattern and knee mechanics after unicompartmental knee arthroplasty (UKA) or BKA.…”

[4][5][6][7][8] To verify the advantages of BKA, it is crucial to compare its functional results with TKA, which is presently considered the standard of care for severe MPFOA.…”
