NCT05533671

Brief Summary

There is no consensus regarding whether rehabilitation or surgical management is best for the management of a primary patellar dislocation. Consequently this prospective randomized controlled aims to compare the incidence of recurrent knee dislocations and patient reported outcomes of patients with primary patellar dislocations managed with surgery (medial patellofemoral ligament reconstruction) compared to non-operative management (a standardized rehabilitation protocol, control group).

Outcome Measures

Primary Outcomes (9)

  • Change in Kujala Questionnaire Score at 2 weeks

    The Kujala questionnaire assess symptoms and limitations that a patient may experience as a result of a knee injury. Scores range from 0-100 with a higher score indicating less limitation. Scores will be reported at each time point.

    Baseline and 2 weeks

  • Change in Kujala Questionnaire Score at 6 weeks

    The Kujala questionnaire assess symptoms and limitations that a patient may experience as a result of a knee injury. Scores range from 0-100 with a higher score indicating less limitation. Scores will be reported at each time point.

    Baseline and 6 weeks

  • Change in Kujala Questionnaire Score at 3 months

    The Kujala questionnaire assess symptoms and limitations that a patient may experience as a result of a knee injury. Scores range from 0-100 with a higher score indicating less limitation. Scores will be reported at each time point.

Study Arms (2)

Operative Group

EXPERIMENTAL

This group will have surgical procedure called a medial patellofemoral reconstruction where the kneecap is anchored back into its correct position)

Procedure: medial patellofemoral reconstruction

Non-operative group

ACTIVE COMPARATOR

This group will have physical therapy for their knee dislocation by following a specific rehabilitation plan.

Procedure: Non-operative group

Interventions

Surgery to correct dislocated (knocked out of place) knee cap. This surgery anchors the kneecap back into the correct position and supports the kneecap.

Operative Group

Physical therapy by following a specific regimen.

Non-operative group

Model Details: This study will be a prospective randomized controlled trial investigating outcomes (recurrent dislocation rates and participant reported outcomes) in two groups of participants following a primary patella dislocation. Half of the participants will be randomized to operative intervention with a standard medial patellofemoral ligament (MPFL) reconstruction and the other half will be randomized to conservative management with a standardized rehabilitation protocol (non-operative group).
