Question: Do complication rates differ between daily and weekly
pin-site care in patients in whom an external fixator has been used to
stabilize a high tibial osteotomy in the treatment of gonarthrosis of the
knee?Design: Randomized (unclear allocation concealment), unblinded,
controlled trial with follow-up to pin removal.Setting: A university hospital in Lund, Sweden.Patients: 50 patients (mean age, 54 y, 62% men) undergoing surgery
for gonarthrosis by the hemicallotasis technique with use of 2
hydroxyapatite-coated pins in the metaphyseal bone and 2 standard conical pins
in the diaphyseal bone. The Orthofix T-garche was used for external fixation.
Complete follow-up was achieved for all patients.
