What this Trial Is About
Researchers are studying ankle and hindfoot conditions caused by biomechanical changes in this area. The trial focuses on how surgical treatments aimed at improving these biomechanical problems may relate to clinical improvements. A special 3D Multisegment Foot Model has been developed and validated to assess these biomechanical changes more precisely, and it is now used routinely at the gaitlab of UZ Leuven. The study evaluates patients who have undergone ankle or hindfoot reconstruction surgery. It uses advanced biomechanical assessments combining plantar pressure measurements and detailed 3D gait analysis with the Multisegment Foot Model. This integrated approach allows researchers to examine many biomechanical parameters within the foot and ankle region before surgery and one year after surgery. Participants will have assessments before their surgery and at multiple follow-up points including 6 months and 1 year after surgery. These assessments include gaitlab measurements, foot function questionnaires, health surveys, and pain scales. The study aims to link clinical outcomes with detailed biomechanical data, helping to better understand the effects of reconstructive surgery on foot and ankle function over time.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Being routinely scheduled for reconstructive surgery for conditions such as Pes Planus, Pes Plano-valgus, or Posterior Tibial Tendon Dysfunction
- Undergoing tibio-talar arthrodesis or prosthesis
- Undergoing sub-talar, partial Chopart, or triple arthrodesis
- Undergoing pantalar arthrodesis with or without inclusion of the Chopart joint
- Age 18 years or older
You will not qualify if you...
- Age under 18 years
- Need for walking aids (e.g., walker or crutches) to walk less than 100 meters
- Inability to walk at least 100 meters
- Leg length differences exceeding 3 centimeters
- Extreme inward or outward turning of the feet (in-toeing or out-toeing)
- Body mass index (BMI) over 27.5 that may prevent accurate placement of markers for biomechanical analysis, to be judged individually
