Durant’s Five-sport standout Kendall Dierickx fighting her way back from devastating knee injury with the help of Rock Valley Physical Therapy

In a small school setting – and a great place like Durant (Iowa) High School falls under that kind of umbrella – losing a gifted, five-sport athlete and tremendous teammate, leaves an enormous void.
That’s right, FIVE sports. Volleyball, softball, track, basketball, and golf without an important piece to their respective puzzle.
In the fall of 2025, Kendall Dierickx, a starter in all 33 games as a freshman on a Durant softball program that made it to the state finals, who played a solid role on the varsity volleyball squad as a freshman, and was a valuable contributor to the basketball, golf and track teams, suffered a major knee injury.
Beyond modest, the ultra-talented Dierickx – while playing against rival Mid-Prairie and taking a set near the referee’s stand at the side of the net – went up for a kill. When Dierickx landed, her left knee came apart, tearing the ACL (anterior cruciate ligament), MCL (medial collateral ligament), and the meniscus (the c-shaped pad of rubbery cartilage in the knee that acts as a shock absorber between the thighbone (femur) and shinbone (tibia).
In an instant, five Wildcat teams were without a consummate teammate and an important piece to their respective successes.
“I knew when I landed, I was in trouble,’’ Dierickx said. “I felt a rip, I heard a rip, and I heard the pop in my knee. I was struggling, upset, emotional.’’
In November of 2025, three days after a successful surgery performed by Dr. Andrew Bries, the hard-working 16-year-old was under the watchful and gifted eyes of Rock Valley Physical Therapy's Jennifer Jasper, PT, DPT, CCVR.
Soon, Kelly Kersten, PT, DPT, SCS, ATC/L, Clinic manager at Rock Valley’s Blue Grass, Iowa, location (413 S Mississippi St. (563) 381-8793), would join in the bettering the life of a hardworking teenager looking to return to her busy athletic life.
“She’s been incredible in the effort she has given to get to where she is today,’’ Kersten said, noting that Dierickx – once she completes her physical therapy – will work with a strength and conditioning expert, and then will be asked to pass a strength and agility mandate from Dr. Bries before returning to action. “There is some work still to be done, but if she continues give the great effort she has for all these months, she will get back to competing.’’
What competition will look like is up to Dierickx, who also starred for Iowa Select (volleyball) before excelling on the high-school level in volleyball.
“It’s going to be all five,’’ Dierickx said of the sports she is looking forward to competing in, noting that summer (2026) softball is not in the plan, but returning for volleyball when school starts is a goal. “I feel great, but I’m waiting to see it (the light at the end of the tunnel). I know it’s coming, but it’s simply hard to know when I will see it.’’
While paying tribute to all who have helped her get this far following her injury, Dierickx, was straightforward on how hard it was – after being so involved – to watch her teammates move on without her.
“I wanted to be there for them. The hardest thing is watching my favorite people do my favorite things and not being able to contribute,’’ said Dierickx, who said her mother Tessa’s positive and first-hand rehabilitation experience with Rock Valley Physical Therapy led to her family’s decision to choose Rock Valley/Blue Grass for her rehabilitation. “My coaches and teammates were always there for me – they were great – but it can be hard because they didn’t experience what I was going through.’’
Kersten says Dierickx has shown a mixture of determination, grit, and amazing maturity to get where she is today.
“It’s hard, what Kendall has been dealing with,’’ Kersten said while running the junior-to-be through a bevy of agility and strengthening exercises inside the Rock Valley’s Blue Grass clinic.
A slew of exercises, it must be noted; Dierickx executed with great determination and skill.
“She had something – lots of things actually – taken from her, yet Kendall has been diligent in her rehabilitation and done everything we have asked of her,’’ added Kersten, who has been the clinic manager in Blue Grass – a wonderful town he has come to enjoy – since January of 2026. “Her family has been great in support of what she has been through, and she says her teammates and coaches have been great, but it’s just Kendall going through all the strengthening and agility exercises to get where she is. There is lots of support, but in the end it’s just her doing the work to reach her goals. That can be tough and can be lonely. Her desire to get back to play shows in her effort.’’
A standout athlete in his own right and one who still competes in triathlons and distance-running events, Kersten has won the praise of Dierickx.
"He’s great; he listens and will always talk me through something,’’ Dierickx said of Kersten. “He knows what he is doing and is always pushing me in a good way. It helps when he tells me that nothing is wrong; it’s just that something is going to be sore along the way. You can let that be an obstacle, but Kelly helps ease your mind.’’
For Dierickx – who holds a summer job at the famous 5th Ave. Creamery in Durant – the door is open to continuing her athletic career – in volleyball – at the collegiate level. Her wish to someday become an anesthesiologist, however, tops her goal-reaching priority list.
“I had plans from my freshman year into my sophomore season – before the injury – of playing volleyball in college,’’ Dierickx said. “But that changed with the injury. I’d love to have a career in medicine and that would be quite challenging and comes with a lot of schooling, so I have thought about just going to college and not playing. We will see how things go.’’
And thanks to her dogged determination and the work of two great therapists from Rock Valley Physical Therapy, things today are going in the right direction for the five-sport standout.
