The patients will then be divided into two control groups: one group will undergo reconditioning through the Delos system and one group will undergo standard rehabilitation treatment.~Primary outcome: improvement of joint stability and postoperative proprioception after reconditioning with the Delos system.~Secondary outcomes: improvement of performance indicators and reduction of disability and satisfaction and assessment of long-term ankle stability after reconditioning with Delos system.
The objective of the study is to evaluate post-operatively the postural control through the Delos system with the Riva method of patients already treated surgically of external capsulo-ligament reconstruction due to ankle instability.
