Brief summary

The aim of this multicenter non-controlled study is to develop a multivariable prediction model of pain/disability improvements in patients with meniscal tears, after a physical therapy treatment based on therapeutic exercise and education.

Detailed description

A multivariable prediction model for the improvement in shoulder pain and disability will be developed based on the following predictors: * Body mass index \[kg/m2, Fractional polynomials FP2\]. * Smoking \[Years, linear relationship\]. * Employment status \[3 categories\]. * Maximum education degree \[4 categories\]. * Previous performance of physical exercise \[2 categories\]. * Baseline disability (measured with the Knee Injury and Ostoarthritis Outcome Score) \[Fractional polynomials FP2\]. * Baseline pain intensity (measured with a numeric pain rating scale) \[Fractional polynomials FP2\]. * Pain duration \[Weeks, linear relationship\] * Pain catastrophizing (measured with the Pain Catastrophizing Scale) \[Linear relationship\]. * Patient's expectations (measured with the Musculoskeletal Outcomes Data Evaluation and Management System) \[Linear relationship\].

Interventions

Therapeutic exercise program based on individualized progressive resistance exercises performed during 3 months at home, with a frequency of 1-3 sessions per week at the hospital.

OTHEREducation

Education applied during all the therapeutic process, focusing on diverting the patient's attention away from the structural lesion, explaining the relationship between pain/disability and tissue injury, explaining the meaning of pain during exercises, and explaining the objectives of the implemented treatments.

Inclusion criteria

* Degenerative meniscal tears (medial and/or lateral), diagnosed by magnetic resonance imaging. * Traumatic meniscal tears (medial and/or lateral), diagnosed by magnetic resonance imaging, originated 6 months ago or more. * Pain intensity equal or greater to 3 points in a numeric pain rating scale, or a degree of disability in the KOOS questionnaire greater or equal to 15%. * Pain lasting 3 months ore more. * Adequate comprehension of written and spoken Spanish

Exclusion criteria

* Knee ligament injuries at the moment of recruitment. * Presence of hip or ankle pathology that makes it impossible to peform knee therapeutic exercises. * History of fracture in the lower limb within the last year. * History of surgery in the lower lim within the last year. * Presence of cancer, fibromyalgia, neurological and/or other systemic diseases. * Cognitive impairment that makes it impossible to perform therapeutic exercise.

Design outcomes

Primary

MeasureTime frameDescription
Knee disabilityBaseline, change from baseline to 3-month, change from baseline to 6-month, and change from baseline to 1-year.Knee disability measured with the Knee Injury and Osteoarthritis Outcome Score, which ranges from 0 (no disability) to 100 (maximum degree of disability).

Secondary

MeasureTime frameDescription
Knee pain intensityBaseline, change from baseline to 3-month, change from baseline to 6-month, and change from baseline to 1-year.Knee pain intensity measured with a numeric pain rating scale, which ranges from 0 (no pain) to 10 (worst imaginable pain).
Need for surgery3-month, 6-month, and 1-year.Need for surgery for the rotator cuff tear registered as a dichotomous variable (YES/NO).

Other

MeasureTime frameDescription
Pain CatastrophizingBaselinePain catastrophizing measured with the Pain Catastrophizing Scale, which ranges from 0 (minimum degree of catastrophizing) to 100 (maximum degree of catastrophizing).
Patient's expectationsBaselinePatient's expectations of improvement with therapeutic exercise measured with the Musculoskeletal Outcomes Data Evaluation and Management System, which ranges from 0 (minimum degree of expectations) to 100 (maximum degree of expectations).
