Injury Outlook: Allen Robinson’s ACL

The people of Twitter have spoken:















Allen Robinson went down early in 2017 with an anterior cruciate ligament (ACL) tear ending his season before it even started. The injury occurred in early September. What does this mean for his 2018 season? How is he progressing based on what has been made available to the public? Let’s take a look.

Returning to Form

Most NFL athletes who tear their ACLs can return in 9 – 12 months post-surgery. This puts A-Rob on track for training camp and the start of the 2018 season. However, most skill position players don’t fully return to form until 1.5 – 2 years post-operatively (post-op) in terms of productivity. For a full deep dive on ACL information valuable to fantasy owners, check out my previous article.

Now back to Robinson. The Jaguars official Twitter account shared this video 4 days ago.

Therapy & Treadmills

Based on everything we know right now, Robinson is progressing as expected. Most running programs post-op start anywhere from 12-weeks to 4-months. The earlier window running programs are typically performed on specialized treadmills to decrease weight bearing and impact or running to the joints. The above video shows Robinson running on two common forms, an Alter G, and a HydroWorx Therapy treadmill.

Alter G Treadmill

This uses some pretty cool technology to unweight the athlete’s body. This can allow an athlete to start running when they may not be ready to do so on a standard treadmill or the ground.

HydroWorx Therapy Pool

The sweet thing about this bad boy is that the floor of the pool is actually a treadmill. It can be raised or lowered to the desired height. There are cameras so the athlete can see their running mechanics on the TV screens. There are also jets that can be turned on to increase the difficulty of running or jogging. We are getting one of these at our clinic and I am super pumped.

Professional athletes typically start with these unweighted treadmills to help them build confidence or to aid them in running when there is still some weakness present. The most encouraging part of the entire video is that Robinson is shown running on solid ground in straight lines without cutting. Everything points to him progressing right on schedule, and I would expect nothing less from a professional athlete of his caliber and the world-class rehab staff and clinicians that NFL organizations employ. The video also shows him working on jumping and landing, which is a staple of rehabilitation for this injury and is particularly important for a WR that excels in ”Randy Mossing” DBs. For those interested in a deeper dive and explanation on hop testing and return-to-play criteria, I previously covered it in an article on Carson Wentz.

Bottom Line

All things considered, A-Rob should be good to go Week-1 of 2018, but don’t be surprised if it takes him a week or two to get acclimated.
