The goal of this trial is to test if functional proprioceptive stimulations combined with continuous passive movement is more efficient than continuous passive movement alone to recover knee joint mobility after anterior cruciate ligament reconstruction in adults. It will also learn about the influence of functional proprioceptive stimulations on pain and pain medication. The main questions it aims to answer are:

• Does functional proprioceptive stimulations combined with continuous passive movement increase knee joint mobility more than continuous passive movement alone?
• Does functional proprioceptive stimulations combined with continuous passive movement reduce perceived pain and pain medication use more than continuous passive movement alone? Researchers will compare functional proprioceptive stimulations combined with continuous passive movement to continuous passive movement alone to see if functional proprioceptive stimulations combined with continuous passive movement is more efficient than continuous passive movement alone.

Participants will:

• Follow a supervised rehabilitation intervention comprising functional proprioceptive stimulations combined with continuous passive movement or continuous passive movement alone during five days a week for 2 weeks
• Attend the clinic five days a week for 2 weeks for rehabilitation, checkups and assessments

Inclusion Criteria:

• participants with isolated ACL rupture
• ACL reconstructed with a four-stranded semitendinosus or ex-tra-articular tenodesis autograft
• enrollment in the rehabilitation program between the fourth and seventh postoperative day

Exclusion Criteria:

• previous ligament reconstruction of the involved knee, reconstruction using quadriceps or patellar tendon autograft
• presence of major neurological or musculoskeletal disorders (e.g., multiple trauma, Parkinson's disease, cerebral palsy, stroke, Alzheimer's disease, dementia…)
• presence of cognitive impairment (i.e., Mini Mental State Examination score < 18)
• body mass index greater than 35 kg/m².
