During knee rehabilitation, isokinetic strength testing can lead to unexpected injuries. An acute patellar dislocation occurred in a patient

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Rehabilitation Science

Background:

  • Isokinetic training and torque measurements are standard in knee ligament injury rehabilitation.
  • Maximal muscle strength tests monitor rehabilitation progress, evaluating concentric and eccentric muscle power.

Observation:

  • This case report details an unusual event during rehabilitation assessment.
  • An acute patellar dislocation occurred during eccentric testing of the uninvolved leg.

Findings:

  • The injury happened on a Biodex isokinetic dynamometer, a common device for muscle strength evaluation.
  • This highlights a potential risk associated with isokinetic testing, even on the non-injured limb.

Implications:

Related Experiment Videos

  • Clinicians should be aware of potential risks during isokinetic dynamometry.
  • Further investigation may be needed to understand the mechanisms and prevalence of such injuries during rehabilitation.
