Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Regenerative Medicine

Background:

  • End-stage elbow arthritis in young, active patients presents unique challenges due to limitations with traditional total elbow arthroplasty (TEA).
  • Existing alternatives for failed TEA or as primary treatment are often unsatisfactory and may involve weight-bearing restrictions.
  • Current interposition arthroplasty materials lack durability, leading to potential failure.

Purpose of the Study:

  • To evaluate the efficacy of meniscus allograft interposition arthroplasty for painful, end-stage elbow arthritis in young, active patients.
  • To assess pain relief, restoration of motion, and functional improvement using this novel technique.
  • To investigate the potential of meniscus allografts as a durable and anatomically suitable interposition material.

Main Methods:

  • A series of 5 patients with end-stage elbow arthritis underwent meniscus allograft interposition arthroplasty.
  • The procedure involved resurfacing the joint with meniscus allografts and supplemental stabilization using a double internal joint stabilizer.
  • Patients were treated at a single institution between 2021 and 2023.

Main Results:

  • All 5 patients demonstrated improvement in pain.
  • All patients experienced an enhanced ulnohumeral range of motion post-procedure.
  • The technique showed good short-term pain relief and functional improvement.

Conclusions:

  • Meniscus allograft interposition arthroplasty is a viable option for managing end-stage elbow arthritis in young, active individuals.
  • This approach offers significant pain reduction and functional gains, avoiding the limitations of traditional arthroplasty.
  • Further long-term studies are necessary to confirm the durability and sustained efficacy of meniscus allograft interposition.
