Which of the Following Is True About Managing a Tear $\circ$

Which of the following is true about managing a tear of the medial or lateral meniscus?

A) A tear of the peripheral portion (outer zone) of a meniscus does not lend itself well to surgical repair because this portion of the meniscus is avascular and does not heal well.
B) A potential complication of a medial meniscus repair is intraoperative damage to or postoperative entrapment of the saphenous nerve.
C) After meniscus repair,initially avoid knee flexion beyond 60 ^$\circ$ to 70 ^$\circ$ during weight-bearing exercises for about 2 months because flexion beyond this range can displace the repaired meniscus in a posterior direction.
D) After meniscus repair,the knee is immobilized in approximately 45 ^$\circ$ of flexion.
