How to Use This Calculator

Select the Graft type used in surgery: 0 = bone-patellar tendon-bone (BPTB), 1 = hamstring autograft, 2 = quadriceps tendon, 3 = allograft.
Indicate whether a Meniscus repair was performed simultaneously (0 = No, 1 = Yes) — this extends early restrictions.
Enter the patient's Age in years and Sport demand level (0 = sedentary to 4 = elite/competitive).
Set the Pre-injury Tegner score (0–10) and whether this is a Revision surgery (0 = primary, 1 = revision).
Review the milestone timeline including jogging clearance (weeks), return-to-sport (weeks and months), and estimated graft re-tear risk (%).
