None = no involvement or nonsurgical management of a small, stable tear; partial = partial meniscectomy; and repair = meniscal repair.
The values are given as the number of participants. Level-I sports involve jumping, pivoting, and hard cutting (e.g., basketball, football, soccer), and Level-II sports involve lateral motion but less jumping or hard cutting than Level-I sports (e.g., baseball/softball, racket sports, skiing). BPTB = bone-patellar tendon-bone autograft.
The values are given as the mean and the standard deviation. Body mass index (BMI) was higher in both the partial (post-hoc p = 0.049) and repair (post-hoc p = 0.031) groups compared with none but did not differ between the partial and repair groups (post-hoc p = 0.872). ACLR = anterior cruciate ligament reconstruction.
