Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All patients in the retrospective cohort are contacted at least 2 years after surgery (or 1 year after removal) via phone call or letter, informed about the study and asked to participate. In case of informed consent, they are invited to the study site. They are asked to complete the questionnaires and they undergo X-Ray of the affected and the non-affected ankle.
All patients in the prospective cohort are informed about the study and asked to participate in the outpatient clinic. In case of informed consent, they are invited to the study site at least 2 years after surgery. They are asked to complete the questionnaires and they undergo na X-Ray of the affected and non-affected ankle.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control Group
Young and healthy Group of People (18-50 years) without any pathology of the lower limb
Specific provocation test
To compare the results the investigators invite a healthy control group matching in age and gender with the intervention cohort. The control group is informed about the study and asked to participate in the outpatient clinic. In case of informed consent, the participants are invited to the study site. The participants undergo the same provocation test of the ankle, and are asked to complete the specific provocation test. In case of substantial underachievement in the provocation test (\<60% of maximum) an X-Ray of both ankles in a.p. and lateral projection is performed. The aim is to radiologically analyse the ankles, and to rule out any morphological reasons for the above mentioned underperformance.
Ankle Fracture Type Weber B
Young and healthy patients with an operative treated fracture of the ankle (type Weber B)
Specific provocation test
To compare the results the investigators invite a healthy control group matching in age and gender with the intervention cohort. The control group is informed about the study and asked to participate in the outpatient clinic. In case of informed consent, the participants are invited to the study site. The participants undergo the same provocation test of the ankle, and are asked to complete the specific provocation test. In case of substantial underachievement in the provocation test (\<60% of maximum) an X-Ray of both ankles in a.p. and lateral projection is performed. The aim is to radiologically analyse the ankles, and to rule out any morphological reasons for the above mentioned underperformance.
Ankle Fracture Weber C and complex
Young and healthy patients with an operative treated fracture of the ankle (type Weber C or complex fracture)
Specific provocation test
To compare the results the investigators invite a healthy control group matching in age and gender with the intervention cohort. The control group is informed about the study and asked to participate in the outpatient clinic. In case of informed consent, the participants are invited to the study site. The participants undergo the same provocation test of the ankle, and are asked to complete the specific provocation test. In case of substantial underachievement in the provocation test (\<60% of maximum) an X-Ray of both ankles in a.p. and lateral projection is performed. The aim is to radiologically analyse the ankles, and to rule out any morphological reasons for the above mentioned underperformance.
