I think this is similar to what NBA players have done with meniscus injuries. The second Rose knee injury they opted to repair the meniscus and he missed the rest of the season. When he happened again, I'm pretty sure he opted to have it removed and was back shortly after. The tradeoff is that it can shorten your career and/or cause flair ups in the future. Boyd is 35 so maybe isn't as concerned about the long term ramifications.
