BACKGROUND AND PURPOSE Tibial tubercle osteotomy (TTO) is an established surgical technique for exposing the stiff kneein revision total knee arthroplasty (RTKA). The osteotomy is usually performed through the anterior metaphyseal cancellous bone of the tibia but it can be extended into the intramedullary canal if tibial stem and cement removal are necessary. Furthermore, repeat osteotomy may b...

There are several theoretic advantages of using intramedullary rod fixation for tibial osteotomy fixation. We performed a retrospective review of patients who were treated with a mid-diaphyseal osteotomy of the tibia fixed with an intramedullary rod for isolated, symptomatic tibial torsion. Forty patients (59 tibias) were included in the study and were followed for a minimum of 12 months or unt...

OBJECTIVE To compare the plateau-patella angle method to the methods already established for patellar height measurement in patients undergoing high tibial osteotomy. METHODS This is a retrospective study of 13 patients undergoing medial opening tibial osteotomy. The patellar height was measured in pre and post-operative radiographs by the methods from Insall-Salvati, Caton-Deschamps, Blackbu...

BACKGROUND Varus deformity increases the risk of progression of medial compartment knee osteoarthritis. The aim of this study was to investigate the clinical and radiographic mid-term results of closing-wedge and opening-wedge high tibial osteotomy when used to treat this condition. METHODS From January 2001 to April 2004, ninety-two patients were randomized to receive either a closing-wedge ...

To assess migration of the tibial component we used roentgen stereophotogrammetric analysis in 40 patients who had had a total knee arthroplasty after failure of a closing wedge osteotomy and compared them with 40 matched patients after primary total knee arthroplasty. We found no difference in migration over time or in the tendency for continuous migration between the two groups. There were no...

BACKGROUND Superior dislocation of the patella is an uncommon condition that mainly occurs in knees with a high patella and medial femorotibial degenerative arthritis. There are no previous reports of this condition occurring in association with tibial valgus osteotomy. CASE REPORT We report the case of a patient in whom vertical dislocation recurred twice at 4 months after tibial valgus oste...

Symptomatic patellofemoral chondral lesions are a challenging clinical entity, as these defects may result from persistent lateral patellar maltracking or repetitive microtrauma. Anteromedializing tibial tubercle osteotomy has been shown to be an effective strategy for primary and adjunctive treatment of focal or diffuse patellofemoral disease to improve the biomechanical loading environment. S...

BACKGROUND Medial opening wedge high tibial osteotomy (HTO) is a well-described treatment in early medial compartmental osteoarthritis of the knee. However, two undesirable sequelae may follow -patella baja and changes in the posterior tibial slope (TS). MATERIALS AND METHODS We conducted a retrospective study in patients who underwent HTO in our center between September 2009 and February 201...

BACKGROUND AND PURPOSE Most studies on high tibial osteotomies (HTOs) have been hospital-based and have included a limited number of patients. We evaluated the use and outcome-expressed as rate of revision to knee arthroplasty-of HTO performed in Sweden with 9 million inhabitants, 1998-2007. PATIENTS AND METHODS 3, 161 HTO procedures on patients 30 years or older (69% men) who were operated o...
