A lateral parapatellar approach with iliotibial band dissection from the Gerdy tubercle for total knee arthroplasty of the valgus knee

Gerdy’s tubercle as a novel anatomical landmark for the proximal tibial cut in total knee arthroplasty

“…Our research on the effectiveness of using GT as a landmark in TKA is supported by a study that investigated the clinical efficacy of a lateral parapatellar approach with iliotibial band dissection from the GT for TKA in valgus knees. [ 15 ] This approach showed significant improvements in pain and function without deviation of the lower limb mechanical axis or prosthesis position, underscoring the practical utility of focusing on GT in TKA procedures.…”

Valgus deformiteli dizde total diz protezi

“…Valgus artritik diz sıklıkla hipoplastik lateral kondil, lateral tibial platoda kemik kaybı, tibianın dış rotasyon deformitesi, femoral ve tibial metafiziyel valgus açılanması ve patellar dizilim bozukluğu ile karakterize karmaşık bir deformitedir. [4,8,9] Ayrıca iliotibial bant (İTB), dış yan bağ (DYB), posterolateral kapsül (PLK), arka çapraz bağ (AÇB) ve popliteus tendonu (POP) gibi lateral yumuşak doku yapılarının kontraktürü ile eşlik eden instabilite bulunabilir. [4,6,8] Nadiren gastroknemiusun lateral başı (GLB) ve biseps femorisin uzun başı da etkilenir.…”

Common peroneal nerve palsy after TKA in valgus deformities; a systematic review

“…The selection of ligaments to be released depend mainly on the tightness of the ligaments in extension and/or flexion. Ligaments can be released through pie-crusting [7,13,20,[22][23][24][25], a subperiosteal release [13,23,[26][27][28] or in a transverse manner. Also, shifting the insertion of a ligament by use of an osteotomy (OT), like a lateral femoral epicondyle osteotomy (LFEO) [29][30][31][32][33][34][35][36][37] or medial femoral epicondyle osteotomy (MFEO) [30,33] is used.…”
