underwent successful core muscle surgery last week and is now on the team¡¯s injured reserve list. What does that mean https://www.thechiefsfanshop.com , exactly? For that, we bring in our in-house injury expert, Aaron Borgmann.We found out last week that a player for the Kansas City Chiefs had surgery to repair something known as a core muscle injury. Since that term is somewhat new in the sports injury world, let¡¯s break it down a bit and describe the situation for those who may not know much about it.When I first started my sports medicine career, this injury was known by the terms, ¡°sports hernia,¡± ¡°goalie groin,¡± and sometimes, ¡°athletic pubalgia.¡± These names have gone by the wayside due to their lack of specificity and inaccuracy. At its most basic explanation Kansas City Chiefs Customized Jerseys , this condition is defined by tearing or multiple small tears of structures that attach to your pubic bone. Think of a suspension bridge ¨C the bones are the steel or concrete girders and the muscles are the tension cables. If one cable is fraying, the whole system is going to not support correctly. (area of discussion is focused to yellow portion of bone highlighted)It is important to note that due to the various structures that attach here (groin muscles from below, as well as abdominal muscles from above) that symptoms for this condition as well as onset can vary quite a bit. It can be chronic or acute, sharp or dull, debilitating or something people can play through. It really does all depend on the amount of damage that the athlete has sustained. Since there are over a dozen variants of how this condition may present itself, accurate diagnosis of what structures need to be repaired is key. Specific MRI images or ¡°cuts¡± can assist with this.It should also be noted that some athletes discover that they have this condition and elect not to have surgery and instead rehab through it. There are many successful cases of this as well. As with anything else, this is very athlete and specific condition dependent.Due to the fact that we were told this athlete suffered from the groin variant we can break that down a bit and tease out what the most likely intervention was. With the groin (adductor) muscles being involved the most likely intervention was either an adductor release (where the muscle is completely cut and allowed to scar down on its own) or a full-on repair (where it is sutured together). The release of a muscle sounds like it would be a bad thing, but there are enough other supporting structures to help pick up the slack and return to function and pain relief are the goals here. Rehab here is interesting and unique. Many surgeries call for a rest period, but not here. Within the first couple of days Kansas City Chiefs T-Shirts , post operation, the first thing you do is walk a mile on the treadmill. Doesn¡¯t matter how long it takes or how fast you go, you walk a mile. Sounds crazy, but this is done to help the repair scar in. I have seen it take 80 minutes, I have seen people do it in 25 (again, this is very dependent upon the patient what structures had to be repaired). Specific soft tissue work over the repaired structures and a lot of ice assists in pain relief early on. Rehab continues with a lot of specific sequential muscle firing and how to learn to use your true core muscles (things like multifidus and transverse abdominus ¨C NOT ABS) to help support your pelvis. There is additional work done including lots of resistance in key positions to stress the supporting structures is beneficial here. Think of lunges and squats with rubber-band resistance while firing your pelvic floor muscles. It¡¯s not easy!Athletes generally feel pretty good within a matter of weeks and some surgeons will tell you that they can return to play at this point. This has not been my experience and have always thought to avoid re-injury here that it was better to give the athlete more time and truly get the rehab portion of this injury correct.No matter the variance, these repairs all have good outcomes in my experience. The surgery is quick, as well as minimally invasive. The rehab generally goes smoothly. No matter when this athlete returns you can probably assume that he will be 100 percent when back on the field.Aaron Borgmann is the founder of Borgmann Rehab Solutions.

This is part two of a three-part weekly film analysis on the performance of Patrick Mahomes. Part one here.This wasn¡¯t the flashiest week we¡¯ve seen from Patrick Mahomes to date. In fact, it might be the least exciting of all the games we¡¯ve seen from him. Regardless of that https://www.thechiefsfanshop.com/hats , this was a fantastic performance for a multitude of new and consistently prevalent reasons. To add to that, there isn¡¯t obvious regression in any area. It¡¯s all moving forward.Something smartThis is a savvy play for such a young quarterback.There¡¯s less than a minute remaining in the first half and the Chiefs are looking to add to their 14-point lead. The Chiefs run a Four Verticals concept against 2-man coverage, a split-safety look with man coverage underneath.Against 2-man coverage, the quarterback isn¡¯t accounted for. With defenders blanketing all routes in man coverage, defenders don¡¯t have eyes on the quarterback. It¡¯s a run alert for quarterbacks. On this play, Mahomes identifies the coverage and knows he can beat it with his legs. As the routes get down the field, Mahomes elects to break for yards. Mahomes is able to outrun the pass rushing Sam Hubbard out of the pocket. Linebacker Vontaze Burfict, in man coverage on running back Damien Williams, falls off to pursue Mahomes as he races by.Mahomes is able to gain 20 yards on the run Kansas City Chiefs Hoodie , but does something additionally smart to end the play. Knowing the time situation, he runs out of bounds after a big gain to stop the clock. The Chiefs eventually end this drive with a field goal. It was a smart play to run based on coverage and even smarter to quit while he was ahead to conserve time.Something specialThere weren¡¯t too many big plays downfield, but being able to finish this one isn¡¯t normal.Receiving the ball to start the second half, the Chiefs elect to take a shot on the first play. They have a variation of the Mills concept (curl with a post over the top of it) with Kelce running the curl, hoping to pull the safety down to hit the post. With inside leverage on the cornerback running with Watkins, Mahomes elects to take the shot. As he sets up to throw, defensive end Carlos Dunlap reaches and forces Mahomes to hitch up further into the pocket. Dunlap actually gets a hand on Mahomes and forces another slight step up. Some of the momentum Mahomes was trying to generate was lost in the evasion of Dunlap. The throw won¡¯t have as much behind it as Mahomes intended. He wanted to allow Watkins the chance to run underneath it. Lesser arm talent would not be able to get the ball 52 yards in the air the way Mahomes was able to on this play. Watkins does a great job adjusting his route to get to the ball and finishes the play for a gain of 50 yards. Everything wasn¡¯t perfect and Mahomes wasn¡¯t able to get all he wanted behind the ball, but it didn¡¯t matter. The arm talent still shines when things don¡¯t go as planned. It¡¯s hard to beat this kid.
