The Unstable Kneecap - the Impact of Anatomy on Function

NCT02569931 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

No results posted yet for this study

Summary

The principal objective of the study is to find out which everyday activities make the kneecap unstable in people with patellofemoral instability.

Analysing how a patient with an unstable kneecap walks will help us to determine if surgery is successful in these patients by seeing if better scores on patient questionnaires are found in patients following surgery and whether these patients also have a better pattern of walking.

The investigators aim to use cameras and pressure pads to see how patients walk before and after surgery and see how this compares to patient scores on the questionnaires.

If the investigators find that patients walk better after surgery they can justify that surgery is worthwhile for the patient and cost effective for the NHS.

Conditions

  • Patellar Dislocation

Interventions

OTHER

Gait analysis

Participants will be asked to walk on an instrumented treadmill. The study group will undergo gait analysis before surgery and 6 months after surgery. The control group will undergo gait analysis at one visit only.

OTHER

Electromyography

Participants in the study group will undergo electromyography before and 6 months after surgery. Participants in the control group will undergo electromyography at one visit only

PROCEDURE

Intra-operative tracking and pressure measurements

Participants in the study group will undergo intra-operative tracking and pressure measurements to see if corrective surgery to stabilise the patella improves tracking and pressure measurements
