The purpose was to assess knee function outcomes between early arthroscopic partial meniscectomy(APM) and delayed APM for patients with degenerative meniscus lesions(DMLs)
Whether early APM surgery or delayed APM surgery will more benefit for patients with DMLs. The study was to determine the early APM vs delayed APM effect on knee function outcomes for patients with DMLs for 1 year follow-up.

the Knee Injury and Osteoarthritis Outcome Score (KOOS) change
The Knee injury and Osteoarthritis Outcome Score (KOOS) holds five subscales including: Pain (9 items); other Symptoms (7 items); Activities of Daily Living (ADL, 17 items); Sport and Recreation function (Sport/Rec, 5 items); and knee-related Quality of Life (QoL, 4 items). Each subscale is scored separately from zero (extreme knee problems) to 100 (no knee problems)
Time frame: change from baseline up to 12 months
International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC Score) change
The International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC) score questionnaire contains 18 items (7 items for symptoms, 1 item for sport activity, 9 items for daily activities, and 1 item for current knee function.) The total score is transformed to a value on a scale of 0 to 100, with 100 representing the highest knee function and 0 is the worst.
Time frame: change from baseline up to 12 months
Kellgren-Lawrence (K/L) grade change
Kellgren-Lawrence (K/L) grade via X ray
Time frame: change from baseline up to 12 months
the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) change
Te WOMAC is a self assessed health status scale for patients consisting of 24 items in three subscales of pain (5 items), stiffness (2 items), and physical function (17 items). All items are scored from 0 (asymptomatic) to 4 (very severe), and the total score ranges from 0 to 96, with higher scores indicating more severe symptoms
Time frame: change from baseline up to 12 months
KOOS pain score change
The minimum is 0 points, the maximum is 4 points, from extreme knee problems to no knee problems. After the score of each part is calculated separately, it is converted into a percentage score by the conversion formula.
