An observational study in Valgus Malalignment of the Knee, sponsored by University Hospital, Basel, Switzerland. Completed at 1 site in Switzerland. Per ClinicalTrials.gov, last updated 2022-03-15.
Sponsored by University Hospital, Basel, Switzerland · Observational
This study is to analyze the indications of the two most popular techniques of distal femoral osteotomy (DFO) performed in patients with valgus malalignment and symptomatic degenerative changes in the lateral compartment of the knee and to evaluate the clinical and radiological outcome of a case series of patients who have received this operation at the Department of Orthopaedics and Traumatology and the Department of Surgery of the University Hospital Basel.
University Hospital, Basel, Switzerland is the lead sponsor of 968 studies on the registry; 191 are open to participants now.
Counted across the registry records on this site, refreshed daily.
All patients who received a DFO for valgus knee arthritis at the Clinic of Orthopaedics and Traumatology at the University Hospital Basel between 1.1.2013 and 31.12.2017 will be included in this study.
Exclusion Criteria:
Other: Data collection from routine medical records
Other: Data collection from routine medical records
Data collection from routine medical records (clinical and radiological data)
Accuracy of the correction of the deformity
The mechanical axis of the femur and the tibia and hence the mechanical tibiofemoral angle (MFTA) will be measured pre- and postoperatively. (the goal of the operation is a neutral alignment, MFTA angle of 0°)
Time frame: at Baseline
incidence of disruptive hardware
Information regarding the incidence of disruptive hardware and of hardware removal operations because of this, time needed until bony union is achieved, complications, delayed and non-union rates and need of conversion to arthroplasty
Time frame: at Baseline
pain level
Information regarding pain levels measured with visual analog scale score (VAS). The visual analogue scale (VAS) is a scale used to determine the pain intensity experienced by individuals. It consists of a line, approximately 10-15 cm in length, with the left side signifying no pain with a smiling face image and the right side signifying the worst pain.
Time frame: at Baseline
