The prevalence of lumbar disc degeneration in symptomatic younger patients: A study of MRI scans.

Study Design: Retrospective Cohort Study.

Objective: Low back pain (LBP) and radiculopathy present a significant burden to patients and healthcare systems. Lumbar disc degeneration (LDD) is associated with LBP.

The use of MRI in the investigation of lateral meniscal tear post medial unicompartmental knee replacement.

The evaluation of lateral knee pain in patients with a medial unicompartmental knee replacement (UKR) is complex. The native lateral compartment structures are prone to the same injuries as patients with normal knees. Historical reports of lateral meniscal injury post medial UKR have argued MRI evaluation is obsolete due to artefact caused by the prosthesis.
