The knee index is an evaluation developed to assess patients with a knee pathology or who have had surgery.
Using the knee index, therapists are able to plan a personalized rehabilitation program to meet a patient’s specific and individual needs.
The knee index is a solution created to combine evaluation and rehabilitation in a simple and automatic way for the therapist, while providing the ability to modify individual rehabilitation parameters unique to each patient.
The knee index allows for an evaluation of the patient through tests that determine:
- Proprioceptive deficits in the operated limb
- Load distribution
- Motor Control
- The patient’s progress during the rehabilitation process
- Return to full function by comparing the test indicators of the operated limb with those of the healthy limb
The knee index is the first functional evaluation that is included in the clinical examination carried out by the orthopedic surgeon, that allows to obtain a complete evaluation of the knee.
The knee index provides objective data to help the orthopedic surgeon to support the monitoring of the patient’s progress through the evaluation and rehabilitation process, and a communication tool with the team of physical therapists and physiatrists.
This path, determined by a facility’s workflow and the patient’s need, may consist of an initial assessment (1), followed by a pre-surgery rehabilitation phase (2) and its evaluation, joint replacement and post-surgery phase (3) with further treatment and final evaluation (4). This path is completely modular. The phases may be planned independently of one another depending on the specific needs of the patient and the organization of the facility.
The knee index may also be used within the rehabilitation center for the evaluation and treatment of non-surgical conditions to support the physical therapist throughout the patient’s clinical course of rehabilitation.
Knee index for knee surgery
The goal of knee surgery is to optimize the biomechanics of the knee, improve function and remove pain. Rehabilitation following knee surgery is an essential and fundamental part of its success 1,2/3,4.
Rehabilitation programs focus on range of motion (ROM) recovery and improving stability 5.
Some of the most common problems faced by patients following knee replacement is poor motion control, reduced proprioception and balance 6,7, conditions also common to other knee disorders.
These deficits affect patients’ ability to perform activities such as twisting, swinging, walking on irregular surfaces and changing direction. Various studies have shown that balance training can be helpful in post-surgery functional recovery and rehabilitation 7,8.
These improvements are due to the recovery of joint proprioception and postural control.

Our “Multi-sensors” solution, to be used exclusively with hunova and huno devices, extends the normal use of a single position sensor to three multi-function sensors. This allows the knee index application to have more evaluations and an improved digital recording of ROM, all within dedicated and integrated reports.
