Complications After Medial Opening Wedge High Tibial Osteotomy

Complicações da osteotomia em cunha de abertura medial do joelho: estudo retrospectivo

“…Miller and Downie (9) reported a complication rate of 36.9%, of which 15.2% was loss of correction; 4.3% fracturing of the lateral cortex during the operation; 4.3% fracturing of the lateral cortex after the operation; 4.3% DVT; 4.3% delayed consolidation; and 4.3% pain due to the implant. Spahn (3) reviewed 85 osteotomies, of which 55 were fixed with a medial Puddu plate, and found that 43.6% presented complications (two with hematomas, four with infection, nine with synthesis material failure, eight with lateral cortex fractures and one with DVT).…”

Opening Wedge High Tibial Osteotomy

“…Few complications of HTO are described in the literature Waugh, 1974, Rinonapoli et al, 1998;Song et al, 2007;Gebhard et al, 2011, Hart et al, 2007, Ribeiro et al, 2009, Miller et al, 2009, Meidinger et al, 2011, Gaasbeek et al, 2010. However, due to the continuous development of the technique and of new synthesis materials, new studies should be undertaken in order to evaluate the complication rates according to each modality of HTO.…”

“…Pseudoarthrosis is a rare complication that occurs in up to 5% of cases (Miller et al, 2009, Meidinger et al,2011, Valkering et al, 2009. It mainly occurs when no stability is added at the osteotomy site, or in the absence of bone graft in the opening wedge (Noyes et al, 2000).…”

Complete rupture of the popliteal artery complicating high tibial osteotomy

“…4 The most relevant complications of the medial openingwedge technique are infection, deep vein thrombosis, secondary loss of reduction, fracture of the lateral tibial plateau and delayed-or non-union of the tibial osteotomy. 5,6 Rare but severe complications that have been reported only as case reports include the compartment syndrome, 7 necrosis of the tibial head 8 and injuries of the popliteal neurovascular bundle.…”
