Dear Daud, ACL tear = anterior cruciate ligament, normally if your ACL has tear or damage then there is chance of damage in you MENISCUS Also. So consult with your doctor with your MRI Scan. ACL operation doctors will "reconstruct your ACL" it can not be repaired. if you feel more pain and swelling, it is better to go for ACL Reconstruction operation, because if you remain untreated, after age of 50+ you will get more pain and selling in your knee, so better go for "laparoscopic surgery", and the healing period will be 2X3 weeks you need minimum 2 month rest for best result,
