Post-Market Evaluation of the MISHA® Knee System for Symptom Relief in Subjects With Medial Knee Osteoarthritis
Moximed
Summary
Prospective evaluation of the safety and effectiveness of the MISHA Knee System. The study will collect data on the procedural and long-term adverse events, WOMAC pain and function scores, KSS satisfaction, subsequent surgical interventions, BMI levels, range of motion, UCLA activity level of the subjects, and perform radiographic/x-ray evaluations at clinical visits through 5 years post-procedure. The primary analysis of this study is freedom from device- and procedure-related SSIs at five (5) years post-implantation. This study will also assess device performance in subjects with intact and retained devices and subjects with devices removed prior to study termination and freedom from conversion to arthroplasty through 5 years. Study subjects will be followed over a five-year post-implant period.

Interventions
- DeviceMISHA Knee System
The MISHA Knee System is an extra-capsular knee implant intended to reduce loads on the medial knee. The implant consists of an absorber located between bases fixed with locking screws to the medial cortices of the distal femur and proximal tibia. The implant shares the load with the medial knee joint and articulating ball-and-sockets allow the device to accommodate the natural motions of the knee.
