About this study
Official title: Comparison of the Open Kinetic Chain and Closed Kinetic Chain Strengthening Exercises on Pain, Function, and Health-related Quality of Life in Degenerative Meniscus Tears
This randomized-controlled trial aims to compare the effect of open kinetic chain and closed kinetic chain strengthening exercises on pain, function, and health-related quality of life in degenerative meniscus tears.
Read the detailed description
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).

- Degenerative Disease, Meniscus Tear, Knee Pain Swelling

What is being measured
The primary outcome is the main question the study is designed to answer.
Knee Injury and Osteoarthritis Outcome Score (KOOS)
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.
Measured: Baseline

Measured: At the end of 8-week intervention
Visual Analogue Scale (VAS)
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.

Lysholm Score
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.

Short Form-12 (SF-12)
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.

Questions about this trial
What is this clinical trial studying?
A study testing Open kinetic chain strengthening exercise and Closed kinetic chain strengthening exercise in people with Degenerative Disease and Meniscus Tear, run by Istanbul University - Cerrahpasa at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Knee Injury and Osteoarthritis Outcome Score (KOOS) (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jun 2025.
