Summary

Lateral unicondylar knee arthroplasty (UKA) shows good long-term function and durability for isolated knee joint disease. This study evaluated longer-term outcomes, finding it a reasonable surgical alternative.

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Knee Arthroplasty

Background:

  • Short- and medium-term functional improvements with lateral unicondylar knee arthroplasty (UKA) are documented.
  • Longer-term functional outcomes and durability of lateral UKA require further investigation.

Purpose of the Study:

  • To assess longer-term Knee Society scores and return to activity levels after lateral UKA.
  • To identify any concerning longer-term radiographic findings post-lateral UKA.
  • To evaluate the durability of lateral UKA through survivorship to revision at 10 and 16 years.

Main Methods:

  • Retrospective review of 39 patients (40 lateral cemented metal-backed UKA).
  • Clinical and radiographic evaluations with a minimum 3-year follow-up (mean 12.6 years).

Treatment of Ankle Osteoarthritis with Total Ankle Replacement Through a Lateral Transfibular Approach

Published on: January 24, 2018

  • Analysis of patient demographics, etiologies (osteoarthritis, posttraumatic, osteonecrosis), and survivorship data.

    • Main Results:

    • Prostheses survivorship was 92% at 10 years and 84% at 16 years.
    • The study assessed longer-term functional scores and radiographic findings, though specific results are not detailed in the abstract.
    • Mean patient age at surgery was 61 years.

    Conclusions:

    • Lateral UKA demonstrates reasonable durability and functional outcomes for isolated lateral femorotibial compartment disease.
    • Despite limited indications, lateral UKA is a viable alternative for specific patient populations.
    • Further research may explore optimal patient selection and long-term performance.
