Twins Video
Luckily, the Twins are hopeful that it isn’t as severe as the right quadriceps injury which caused Royce Lewis to miss the first two months of the season.
The adductor muscles provide breaking forces through eccentric muscle contractions (i.e. the muscle is contracting while lengthening) to help control athletic movements. So, it should come as no surprise that groin and adductor strains are among the most common muscular injuries in elite athletes.
The Grade 2 categorization essentially indicates that it is a moderate injury. From an advanced imaging standpoint, this means at least 10% but no more than 50% of Lewis’s muscle fibers were damaged. Because of the wide range of damage, outcomes for Grade 2 strains vary considerably, though most generally heal within six to eight weeks. That would be a rough estimate for Lewis’s return sometime between Aug. 14 and the end of that month.
Now, the question facing Lewis and the Twins, one that is undoubtedly on everybody’s mind: What can be done to prevent this from occurring again?
As I mentioned previously, this is the fourth significant injury Lewis has suffered to his right leg—ACL twice, quadriceps, adductor—since reaching MLB, and the sixth issue (those four, plus strains of his left oblique and left hamstring) that has landed him on the IL. Unfortunately, there aren’t any easy, straightforward answers here.
It’s often said that the best predictor of future injury is past injury, though that saying is only true as it pertains to the same muscle or location. For example, the best predictor of suffering a right ankle sprain is if you previously sprained that right ankle. All of Lewis’s injuries thus far—save for the ACL—are to unique muscles.
Muscle weakness is a common characteristic following ACL reconstruction, yet there is a surprising lack of research looking into the presence and persistence of weakness in muscle groups other than the quadriceps. However, there is evidence that muscle activation patterns (specifically the co-activation of the gluteal and adductor muscles) are impaired for up to two years following surgery. Unfortunately, research going the next step—determining if these impaired activation patterns are associated with greater injury risk—is largely absent.
It’s also important to consider that, as a professional athlete, Lewis has access to elite rehabilitation and strength and conditioning programs. The Twins have been cautious with his rehab and training, and assess his force production (strength, power, etc.) via scientific means such as force plates and dynamometry regularly.
Athletes aren’t cleared to return to play following a major injury until all of their measures have reached or exceeded their pre-injury values. (As far as imbalances go (i.e. one side is stronger than the other), there isn’t much strong evidence to suggest it is an important factor in injury risk mitigation or performance.)
Finally, the most powerful but least satisfying factor needs to be considered: Dumb luck. We don’t like to think that nothing could have been done; that Lewis’s injury was an accident, the simple flap of the butterfly’s wing throwing into motion a chain of events that were unpredictable and uncontrollable.
Suggesting so nullifies the ability to ascribe blame, leaving our frustrations and sympathies simply afloat in the ether. We can’t blame Lewis’s legs or work ethic, nor can we question Nick Paparesta’s treatment philosophy and practices. But often that is done anyway, by the talking heads and individuals with no avenue for venting their frustrations. They label the athlete as “injury-prone”—despite not fully appreciating the complexities of the human neuromusculoskeletal system and injury risk mitigation—and place blame via jumps in logic and correlation-equals-causation thinking.
Losing Royce Lewis sucks--for him, for the team, and for us. We all want to see Lewis batting in the middle of the order and playing a stout third base. But right now, he’s headed for another IL stint. It’s not his fault. It may not even be his body’s fault. It may just be Lady Luck striking yet again.
