Eligibility
Age
16 Years to 40 Years
Inclusion criteria
Inclusion criteria: Inclusion criteria: individuals aged 16 years or older, of both genders, with a history of at least one episode of atraumatic, unilateral or bilateral patellar dislocation. Participants should present at the physical examination a signal of apprehension positive to the lateralization of the patella, pain upon palpation along the medial retinaculum, and increase of the patella inclination or abnormal excursion of the patella (J-sign) to flexion-extension of the knee.
Exclusion criteria
Exclusion criteria: Exclusion criteria: Individuals aged under 16 years and over 40 years, with loss of knee range of motion, with knee immobilized, in use of crutches or cane, with a history of traumatic patellar dislocation, with a history of meniscal injuries or anterior cruciate ligament, posterior cruciate ligament, medial collateral and lateral collateral ligaments injuries. Individuals who have undergone any surgical intervention on the hips, knees, and ankles of any lower limbs will also not be included.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome will be the Lysholm Knee Scoring Scale, with 10.1 points difference considered for establishing clinical significance (difference between groups at the end of treatment and follow-up). The Lysholm questionnaire will be applied at baseline, four weeks after baseline, at the end of treatment (8 weeks) and 12 weeks after the baseline (follow-up). | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcomes will be the Norwich Patellar Instability questionnaire (NPI), Anterior Knee Pain Scale Kujala, LEFS questionnaire (Lower Extremity Functional Scale), and WHOQOL-bref quality of life questionnaire, as well as the Numerical Pain Rating Scale (NPRS) at rest and effort, the number of recurrent patellar dislocation requiring emergency care in the period between assessments and hip and quadriceps muscle strength assessed by isometric dynamometer. The questionnaires, Numerical Pain Rating Scale at rest and effort and the number of recurrent patellar dislocation requiring emergency care will be collected at baseline, four weeks after baseline, at the end of treatment (8 weeks), and 12 weeks after the baseline (follow- up). The assessment of muscle strength using isometric dynamometer will be collected at the baseline and at the end of treatment (8 weeks). | — |
