Functional Outcome Comparison of Implant-Free Bone-Patellar Tendon Autografts Using Press-Fit Fixation Technique and Hamstring Autografts Using Implant in Arthroscopic Anterior Cruciate Ligament Reconstruction: A Prospective Study

Functional outcome score Tegner-Lysholm

时间窗: At 1 month after surgery.

Tegner-Lysholm Score subjectively evaluate to how the knee pain has affected the ability to manage in everyday life. Number of items: 8 items, each scored differently Subscales: 1. limp (0, 3, 5) 2. support (0, 2, 5) 3. locking (0, 2, 6, 10, 15) 4. instability (0, 5, 10, 15, 20, 25) 5. pain (0, 5, 10, 15, 20, 25) 6. swelling (0, 2, 6, 10) 7. stair climbing (0, 2, 6, 10) 8. squatting (0, 2, 4, 5) Total score is given as "excellent" for 95 to 100 points; "good" for 84 to 94 points, "fair" for 65 to 83 points, or "poor" for less than 65 points.

Anterior knee laxity

时间窗: At 6 months after surgery.

Anterior knee laxity (in centimetres) was assessed by measuring anterior translation at 30° of flexion with a rolimeter and comparing it with the contralateral knee.

Functional outcome score International Knee Documentation committee (IKDC)

时间窗: At 6 months after surgery.

International Knee Documentation committee (IKDC) score evaluate improvement or deterioration in symptoms, function, and sports activities. Number of items: 18 subscales: * symptoms: pain, stiffness, swelling, locking/catching and giving-way of the knee. * sports activities: functions such as going up and down the stairs, rising from a chair, squatting and jumping * function and activity of daily living: knee condition prior to injury Response options vary for each item. Item 6 dichotomizes response into yes/no; items 1, 4, 5, 7, 8, and 9 use 5-point Likert scales; and items 2, 3, and 10 use 11-point numerical rating scales. The total score is calculated as (sum of items)/(maximum possible score) × 100. Possible score range 0-100, where 100 = no limitation with daily or sporting activities and the absence of symptoms. Higher values represent a better outcome.

Functional outcome score Knee Injury and Osteoarthritis Outcome (KOOS)

时间窗: At 6 months after surgery.

Knee Injury and Osteoarthritis Outcome (KOOS) measure patients' opinions about their knee and associated problems over short- and long-term followup (1 week to decades). Number of items: 42 items rated on a 5-point Likert scale (0-4) across 5 subscales: * pain frequency and severity during functional activities (subscale score range: 0-36) * symptoms such as the severity of knee stiffness and the presence of swelling, grinding or clicking, catching, and range of motion restriction (subscale score range: 0-28) * difficulty experienced during activities of daily living (ADL) (subscale score range: 0-68) * difficulty experienced with sport and recreational activities (subscale score range: 0-20) * knee-related quality of life (QOL) (subscale score range: 0-16) The 5 dimensions are scored separately as the sum of all corresponding items, and then converted into percentage (score range 0-100). Score of 0 means extreme knee problems and score of 100 means no knee problems.
