NCT06843980

Brief Summary

Prospective, multicenter, two-arm, 2:1 randomized controlled trial (RCT) comparing the benefits in subjects with medial knee osteoarthritis who are treated with either the MISHA Knee System or with non-surgical treatment. This is the first randomized head-to-head study comparing outcomes from subjects treated with the MISHA Knee System.

Outcome Measures

Primary Outcomes (1)

  • WOMAC Pain at 6 Months

    Improvement in WOMAC Pain in the MISHA arm compared to the non-surgical arm measured on the initial cohort who complete the 6-month follow-up visit

    6 Months

Secondary Outcomes (1)

  • WOMAC Function at 6 Months

    6 Months

Study Arms (2)

MISHA Knee System

EXPERIMENTAL

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.

Device: MISHA Knee System

Non-Surgical Treatment

ACTIVE COMPARATOR

The non-surgical arm includes assist devices, physical conditioning, prescription or nonprescription medications, creams, vitamins, or supplements, intra-articular Injections, physical therapy and weight loss.

Other: Non-Surgical Treatment

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Activity exacerbated knee pain isolated to the medial compartment and not global in nature
  • WOMAC pain ≥ 40
  • Failed to find relief in non-surgical treatment modalities

You may not qualify if:

  • Large medial osteophyte(s) or considerable extruded meniscus that may interfere with the placement or function of the device
  • Poor bone quality (e.g., bony erosion, osteopenia, osteoporosis)
  • Ligamentous instability
  • Active or recent knee infection
  • Inflammatory joint disease, including sequelae of viral infections
  • Suspected or documented allergy or hypersensitivity to cobalt, chromium, nickel or other metals
  • History of keloid, hypertrophic or contracture scaring
  • Propensity for restrictive scar formation or adhesions with prior procedures
