This study is a multicenter non-randomized single-blind controlled trial, aimed at investigating the feasibility and efficacy of hydrotherapy based on IVR, for the patients with TKR(Total Knee Replacement), on the function, gait performance, postural balance control, and knee edema reduction. The protocol was draft according to the Consolidated Standards of Reporting Trials (CONSORT ) checklists. A total of 96patients with total knee prosthesis will be recruited and divided into three groups, to receive a traditional rehabilitation (TR) program, traditional hydrotherapy (TH)or hydrotherapy through immersive virtual reality (HIVR) using Bts-Nirvana. Assessments will be performed at baseline and at the end of treatment.
For the study, inpatients will be taken into consideration. A maximum of 17 treatment sessions will be conducted, divided from 3 to 5 training sessions per week. The treatments will be carried out in groups consisting of 3 patients. All patients included in the study will perform 45 minutes of traditional rehabilitation treatments, consisted in: * passive mobilization for the recovery of the complete articular range; * active work on cycle ergometer; * muscle strengthening with isometric and isotonic exercises; * proprioceptive exercises in standing position for load balancing and balance control; * step training with progressive reduction of walking aids; * recovery of autonomy in the ascent and descent from the stairs; * recovery of autonomy in daily life activities. In addition to this common program, specific knee therapy will be performed as provided in the three groups. Traditional Rehabilitation (TR): the TR group exercises will be performed in the gym with a physiotherapist. In particular, patients will perform: * exercises with a patient sitting on a chair (3 minutes per exercise): * flexion-extension of the knee; * leg and hip circling; * flexion-extension of the ankle; * triple flexion; * walking (with and without aids). Traditional Hydrotherapy (TH): the TH group exercises will be performed in a swimming pool suitable for hydrotherapy treatments. In particular, patients will perform: * exercises with patients sitting on the swimming pool edge with lower limb immersed in the water; * flexion-extension of the knee; * leg and hip circling; * flexion-extension of the ankle; * triple flexion; * water walking exercises. Hydrotherapy through Immersive Virtual Reality (HIVR): the HIVR exercises will be performed using Nirvana system, a medical device based on virtual reality specifically designed to support motor rehabilitation, by projecting aquatic scenarios on the floor that simulates the movement and the noise of the water due to the motor exercise execution by the patient. In particular, the following virtual reality scenarios will be used: * "Swimming pool": the environment represents a swimming pool (water and edge). The patient must perform exercises by moving the lower limbs while sitting on a chair. The virtual environment gives the sensation of having the lower limbs immersed in water above the knees; * "Water metal": the environment gives the feeling of being immersed in water up to the waist. The subject interacts with the virtual water performing walking exercises and receiving visual and auditory biofeedback.

Changes in Time Up & Go Test
Time Up and Go test (TUG): TUG is a test used to determine fall risk and measure the progress of balance, sit to stand and walking. The patient starts in a seated position, then stands up, walks 3 meters, turns around, walks back to the chair and sits down. If a patient took 14 seconds or longer to perform the test he was classified as high-risk for falling
Time frame: At baseline (day 1-T1) and at the end (day 21 -T2) of the treatment.
Change in 10-Metre Walking Test (10MWT)
10MWT is used to measure the time (and if required the number of steps) taken for subjects to cover a distance of ten meters from a standing start, when walking at their usual speed, as a measure of the change in aspects of their gait performance
Time frame: At baseline (day 1-T1) and at the end (day 21 -T2) of the treatment.
