Eligibility
Inclusion criteria
Inclusion criteria: - Symptomatic unilateral post-traumatic osteoarthritis of the upper ankle joint - Age 18 - 70 - Patient is able to understand the study procedure and has provided written informed consent
Exclusion criteria
Exclusion criteria: - Existing arthrodesis of the ipsi- and contralateral foot - Bilateral OSG arthrosis - symptomatic (subsequent) arthrosis of the ankles - Secondary gait disorder of neurological/internal or orthopedic origin (e.g. multiple sclerosis, herniated disc, coxarthrosis/gonarthrosis, knee/hip TEP, pelvic fractures, etc.) - Persons taking medication with known effects on the CNS - pregnancy - previous infection close to the joint (bony or soft tissue) - secondary arthritis (e.g. rheumatic) - primary or secondary foot deformities
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main outcome measures regarding the primary study hypothesis are the joint angles [°] at the affected leg between forefoot and hindfoot, hindfoot and tibia (definition according to Oxford Foot Model) and at the knee joint. In addition, the external ankle joint moments [Nm/kg] are analyzed. The data are collected using marker-based gait analysis. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Postoperative satisfaction of the patient and foot function (SF-36, EQ-5D, AOFAS (modified)) - Type and extent of return-to-work (change in occupational activity after surgery, full-time/part-time activity) - Duration of incapacity for work - osseous reconstruction of the arthrodesis after 6 months (routine radiology) - Evaluation of the hindfoot angle achieved intraoperatively and its influence on outcome (preoperative and postoperative Saltzman imaging). - Detect possible predictors of healing progression from gait analysis data. - Survey of pain intensity and localization (NRS scale as part of the clinical examination in the gait laboratory). - Effect of surgical arthrodesis technique on consolidation rate. | — |
