About

Osteoarthritis (OA) is a condition that causes pain and stiffness in the joints, often due to injuries like torn ligaments. Even after surgery, these injuries can lead to long-term joint problems. Current treatments don't fully prevent OA from developing. This study is testing a new 12-week exercise program designed to improve how the knee moves, using a special sensor-based system. The goal is to reduce joint inflammation and prevent the development of OA in patients who have had knee surgery.

Enrollment: 60 estimated patients

Sex: All

Ages: 18 to 50 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Signed written informed consent
• Underwent anterior cruciate ligament reconstruction (ACLR) due to an acute knee injury in the past 12 months
• ACLR patients with aberrant gait profiles who exhibit all three aberrant characteristics (knee flexion angle, knee flexion moment, and knee adduction moment)

Exclusion criteria

• Previous trauma or surgery (other than ACLR) to any weight-bearing joint,
• Signs of knee OA as defined by the OARSI-Joint Space Narrowing (JSN) Score of two or more (standing AP x-ray)
• Body mass index ≥ 30 kg/m2;
• Inflammatory arthropathies;
• Immunosuppression due to illness or medication;
• Sepsis or hemostasis disorders;
• Severe uncontrolled inflammatory disease or autoimmune disease (e.g., ulcerative colitis, Crohn's disease, etc.);
• Having malignancy and undergoing treatment including chemotherapy, radiotherapy, or immunotherapy;
• Unable to freely give their informed consent (e.g., individuals under legal guardianship).
• Currently enrolled in or has not yet completed a period of at least 5 times as the half-life time of the drug used in the previous trial since ending other investigational device or drug trial(s)
• Patients who are dependent on the sponsor, investigator, or study site;
• Pregnant or breast-feeding women or women of childbearing potential not protected by an effective contraceptive method of birth control (defined as pearl index < 1);
• Any form of substance abuse, psychiatric disorder, or other condition that, in the opinion of the Investigator, may invalidate communication with the Investigator and/or designated study personnel;
• Patients who are committed to an institution by virtue of an order issued by either the judicial or the administrative authorities;

60 participants in 2 patient groups

The treatment group

Experimental group

Description:

In addition to the standard-of-care physiotherapy program, the treatment group will additionally receive a training intervention utilizing sensor-based technology that provides 3D avatar training, supported by an accompanying app, to deliver personalized exercise regimens. This intervention aims to correct the pathological knee movement and loading patterns that exacerbate joint inflammation and contribute to the development of knee OA.

Behavioral: Training intervention
