About this study

Patients with degenerative meniscus tears between the ages of 35 and 65 will be randomly divided into two groups: Group 1 (open kinetic chain strengthening exercises) and Group 2 (closed kinetic chain strengthening exercises). Interventions will be applied for 16 sessions (twice a week for 8 weeks). The patients will be assessed at baseline and at the end of the 8-week intervention. The pain during activity, at rest, and at night will be assessed with the Visual Analog Scale (VAS). Active range of motion will be assessed with a digital goniometer. Isometric muscle strength will be measured with a handheld dynamometer. The functional status and symptoms will be evaluated by the Knee Injury and Osteoarthritis Outcome Score (KOOS) and Lysholm Knee Scoring Scale. Health-related quality of life will be assessed with the Short Form-12 (SF-12).

  • Have received steroid injections in the last 6 months
  • Accompanying conditions such as injury to the surrounding ligaments, congenital anomaly in the affected knee, coxarthrosis and spinal stenosis
  • Presence of any systemic disorder that may affect assessment parameters

  • Failure to cooperate with assessments

Treatment and study plan

Open kinetic chain strengthening exercise

Other

A web-based 8-week exercise program consisting of stretching exercises, open kinetic chain strengthening exercises, and functional exercises for the knee and hip will be performed.

Closed kinetic chain strengthening exercise

Other

A web-based 8-week exercise program consisting of stretching exercises, closed kinetic chain strengthening exercises, and functional exercises for the knee and hip will be performed.

Primary outcomes

  1. Knee Injury and Osteoarthritis Outcome Score (KOOS)

    Time frame: Baseline

    Short-term and long-term symptoms and function will be assessed with the Knee injury and Osteoarthritis Outcome Score (KOOS) that is developed as an extension of the WOMAC Osteoarthritis Index. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

Secondary outcomes

  1. Knee Injury and Osteoarthritis Outcome Score (KOOS)

    Time frame: At the end of 8-week intervention

    Short-term and long-term symptoms and function will be assessed with the Knee injury and Osteoarthritis Outcome Score (KOOS) that is developed as an extension of the WOMAC Osteoarthritis Index. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

  2. Visual Analogue Scale (VAS)

    Time frame: Baseline

    Pain intensity will be measured using the visual analogue scale (VAS). The participants will be asked to indicate their perceived pain at rest, during activity and at night on the 10 cm line between no pain and terrible pain. The score will be determined by measuring the distance on 10 cm line using a ruler. The higher scores indicate an higher level of pain.

  3. Visual Analogue Scale (VAS)

    Time frame: At the end of 8-week intervention

    Pain intensity will be measured using the visual analogue scale (VAS). The participants will be asked to indicate their perceived pain at rest, during activity and at night on the 10 cm line between no pain and terrible pain. The score will be determined by measuring the distance on 10 cm line using a ruler. The higher scores indicate an higher level of pain.

  4. Active Range of Motion

    Time frame: Baseline

    Active knee range of motion including flexion and extension will be measured described by the American Academy of Orthopaedic Surgeons (AAOS) using a digital goniometer.

  5. Active Range of Motion

    Time frame: At the end of 8-week intervention

    Active knee range of motion including flexion and extension will be measured described by the American Academy of Orthopaedic Surgeons (AAOS) using a digital goniometer.

  6. Muscle Strength

    Time frame: Baseline

    Isometric muscle strength will be measured with a handheld dynamometer for knee flexors and extensors. The process will be repeated three times in each direction, with the average value recorded.

  7. Muscle Strength

    Time frame: At the end of the 8-week intervention

    Isometric muscle strength will be measured with a handheld dynamometer for knee flexors and extensors. The process will be repeated three times in each direction, with the average value recorded.

  8. Lysholm Score

    Time frame: Baseline

    Functional limitations related to degenerative meniscal tear will be used with the Lysholm Score that is one of the most frequently used functional questionnaires. The total score is the sum of each response to the eight questions, and may range from 0-100. Higher scores indicate a better outcome with fewer symptoms or disability.

  9. Lysholm Score

    Time frame: At the end of the 8-week intervention

    Functional limitations related to degenerative meniscal tear will be used with the Lysholm Score that is one of the most frequently used functional questionnaires. The total score is the sum of each response to the eight questions, and may range from 0-100. Higher scores indicate a better outcome with fewer symptoms or disability.

  10. Short Form-12 (SF-12)

    Time frame: Baseline

    Short Form-12 (SF-12), which is developed based on Short Form-36, consists of 12 items: 7 items dealing with the physical components scores (PCS-12) and 5 items related to the mental components scores (MCS-12) of SF-12. Range of both scores is 0 to 100, where the higher scores indicate better health related quality of life.

  11. Short Form-12 (SF-12)

    Time frame: At the end of the 8-week intervention

    Short Form-12 (SF-12), which is developed based on Short Form-36, consists of 12 items: 7 items dealing with the physical components scores (PCS-12) and 5 items related to the mental components scores (MCS-12) of SF-12. Range of both scores is 0 to 100, where the higher scores indicate better health related quality of life.
