Hip and Knee Surgery

The Oxford Stress System for Knee Arthroplasty Radiographs (OSSKAR) is a medical device for positioning the lower limbs for stress imaging of the knee. The device optimally:
– positions the lower limbs for valgus and varus stress imaging of the knee.
– applies a set and reproducible force to the knee.
– protects the radiographers from x-rays.
– provides better comfort to the patient.

Indications

• Assessment of the pattern and severity of arthritis within the medial and lateral compartments of the adult knee.
• Assessment of the state of the lateral tendons.
