The device "Patello" was designed to passively mobilize the Patella in cranial-caudal direction. Its application field lays in the rehabilitation of any knee pathology where knee range of motion may be restricted due to the Patella mobility.
The effectiveness of the device Patello has not been tested so far. This clinical study aims to assess and proof the effectiveness of this device. The aim is to objectify the movement of the Patella induced by the device Patello in cranial / caudal direction. As outcome parameter serve ultrasound measurements of a bony reference point of the femur and the Patella and its displacement / distance after mobilization.

| Patellofemoral Translation | Patellar cranial-caudal translation (in centimeters) is assessed repeatedly within a single passive continuous mobilization session. A total of 50 repetitions are performed at a constant mobilization speed. Ultrasound video sequences are recorded, and patellar translation is analyzed immediately after 1, 10, 20, 30, and 50 repetitions during the same session. | Assessed after 1, 10, 20, 30 and 50 mobilization repetitions during a single continous passieve patellar moblizitaion session of 50 repetitions (total duration approximately 5-10 minutes) |
