Cohort of Lower-Extremity Sports Injuries and Degeneration(Yongjiang Cohort)

13 augustus 2026 bijgewerkt door: Ningbo No.2 Hospital

Bidirectional Cohort of Lower-Extremity Sports Injuries and Degeneration (Yongjiang Cohort)

This is an observational cohort study conducted at Ningbo No. 2 Hospital. The study will include patients with knee-related sports injuries or degenerative knee conditions who receive routine clinical care. The purpose is to build a standardized real-world clinical cohort and evaluate knee injury, degeneration, recovery, and long-term outcomes.

After informed consent, participants will undergo baseline data collection, including medical history, laboratory tests, questionnaires, X-ray and MRI imaging, and functional assessments. Patients younger than 50 years will mainly be assessed for sports injury and functional recovery, while patients aged 50 years or older will receive additional sarcopenia-related assessments such as grip strength, DXA testing, and gait evaluation.

No experimental treatment, randomization, or intervention will be assigned. Participants will be followed at about 6, 12, and 24 months after treatment or surgery to assess knee function, imaging changes, reinjury, reoperation, pain, quality of life, falls, and functional decline. The study plans to enroll about 500 participants.

Studie Bevolking

The study population will include patients with knee-related diseases or injuries who receive routine clinical care through the orthopedic and sports medicine outpatient, emergency, and inpatient services at Ningbo No. 2 Hospital. Eligible participants will include patients with sports injuries, degenerative knee conditions, or related knee disorders. Participants will be managed according to routine clinical practice and followed as part of an observational cohort.

Beschrijving

Inclusion Criteria:

  • Patients who plan to receive relevant clinical evaluation or treatment at Ningbo No. 2 Hospital and are able to complete baseline assessment.
  • Patients with a clinical diagnosis of knee-related injury or degenerative knee disease.
  • Patients who are willing to provide informed consent and participate in follow-up.

Exclusion Criteria:

  • Patients who are unable to complete the core baseline assessments or have substantial missing key clinical information.
  • Patients with severe comorbid conditions or cognitive impairment that may affect assessment of the main outcomes or prevent participation in follow-up.
  • Patients who are considered by the investigator to be unsuitable for inclusion in this cohort.

Cohorten en interventies

Groep / Cohort
Interventie / Behandeling
Sports Injury Cohort
Participants with knee-related sports injuries as the main clinical condition. This cohort will be observed for injury characteristics, treatment patterns, tissue repair, functional recovery, and subsequent degenerative changes during follow-up.
Ander: Routine Clinical Care
Participants will receive routine clinical care as determined by their treating physicians according to usual clinical practice. The study will not assign any treatment, randomization, or experimental intervention.
Degenerative Knee Disease Cohort
Participants with degenerative knee conditions, including knee osteoarthritis or related degenerative disorders, as the main clinical condition. This cohort will be observed for degeneration severity, symptom burden, imaging progression, body composition, gait changes, and clinical outcomes during follow-up.
Ander: Routine Clinical Care
Participants will receive routine clinical care as determined by their treating physicians according to usual clinical practice. The study will not assign any treatment, randomization, or experimental intervention.

Tijdsspanne: Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Progression of knee degeneration will be assessed using quantitative MRI sequences ( T1/T2 mapping).
Baseline, 6 months, 12 months, and 24 months after treatment or surgery

Maatregel Beschrijving
Tijdsspanne
Change in Knee Function Scores(KOOS)
Tijdsspanne: Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Participants younger than 50 years will be assessed using KOOS scores
Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Change in Knee Function Scores(WOMAC)
Tijdsspanne: Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Participants aged 50 years or older will be assessed using WOMAC scores
Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Change in Cartilage Morphology on 3D DESS MRI
Tijdsspanne: Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Change in cartilage morphology will be assessed using three-dimensional double-echo steady-state magnetic resonance imaging. Cartilage structural changes will be evaluated according to the study imaging protocol, with greater structural deterioration indicating more severe knee degeneration.
Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Change in Proton Density Fat Fraction on Knee MRI
Tijdsspanne: Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Change in proton density fat fraction will be assessed using magnetic resonance imaging. Proton density fat fraction values will be used to evaluate fat-related tissue changes around the knee according to the study imaging protocol.
Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Change in Kellgren-Lawrence Grade on Knee X-ray
Tijdsspanne: Baseline, 6 months, 12 months, and 24 months after treatment or surgery
Change in radiographic knee degeneration will be assessed using the Kellgren-Lawrence grading system on knee X-ray. The Kellgren-Lawrence grade ranges from 0 to 4, with higher grades indicating more severe radiographic osteoarthritis.
