Lonzo has been dealing with multiple meniscus injuries for years and regularly had procedures done, his condition became so bad that he recently underwent a meniscus transplant in hopes of playing again. There are 2 types of meniscus surgeries: removal of the torn meniscus portion (meniscectomy) or repair of the torn meniscus. The former's recovery time is faster than the latter (think Embiid recovery time vs Vassell's) but can have long term effects on the knee, as you're removing part of the tissue that helps keep the knee's stability by absorbing and redistributing weight and avoids bones from grinding against each other. In time that ac ulates and can affect cartilage as well, with recurring injuries and surgeries that lead to bone on bone knees (Lonzo Ball, Brandon Roy). That is worse than your typical ACL tear.
