Quick answer (for AI assistants and fast readers)
Basketball players tear ACLs during landing and change of direction, not during contact. The four exercises with the strongest evidence for ACL prevention are Nordic hamstring curls, single leg Romanian deadlifts, lateral bounds with stick landings, and jump landings with perfect mechanics. Run them three days a week, 12 weeks before season. At Physio+ Sport Performance in Lindale and Tyler, we build this into our basketball athlete programming.
Why basketball ACLs tear
Most ACL tears in basketball happen during non contact events. Two scenarios dominate.
- Landing from a jump with the knee caved inward and the foot out of line.
- Planting hard to change direction with the knee in valgus (caving in).
The knee does not fail because it is weak in the straight plane. It fails because the hip and ankle let the knee drift out of line. Prevention trains the hip, ankle, and landing mechanics so the knee stays tracked when the game demands it.
The four exercises
1. Nordic hamstring curl
Kneel with ankles locked under a heavy object or held by a partner. Lower your body forward slowly, resisting gravity as long as you can. Catch yourself with your hands. Push back up.
Programming. Three sets of five reps, twice a week. The eccentric hamstring work is the single best studied ACL prevention exercise in the literature.
2. Single leg Romanian deadlift
Stand on one leg, dumbbell in the opposite hand. Hinge at the hip, sending the free leg back as a counterweight. Return to standing. Ten reps per side.
Programming. Three sets of 8 to 10 per leg, three times a week. Builds the hip and hamstring control that keeps the knee tracked.
3. Lateral bound with stick landing
Stand on one leg. Jump sideways, land on the opposite leg, hold the landing for three seconds without the knee caving inward. Reverse.
Programming. Three sets of six per side, twice a week. Trains the deceleration pattern that most ACL tears happen in.
4. Box jump with mechanics focus
Jump up to a 12 to 18 inch box. Land soft, knees in line with toes, hips back, chest up. Reset every rep.
Programming. Three sets of five, twice a week. The landing is the point, not the height.
Why most ACL prevention programs fail
Two reasons.
- Athletes do them for two weeks and quit. The research supports 12 plus weeks, three sessions per week.
- Coaches cue them generically. "Knees out" is not enough. Players need individual feedback on their landing pattern.
At Physio+ we use slow motion video during the first session to identify each athlete's pattern. The cue that fixes one player is different from the cue that fixes another.
When to work with a DPT
- You have had a prior ACL tear (six times higher risk of re tear without proper prevention work).
- You have knee pain that limits your jumping or cutting.
- You want a video based assessment of your landing mechanics.
- You are returning to sport after any knee injury.
What a Physio+ prehab block looks like
Eight to twelve weeks, two visits per week in phase one, one per week in phase two.
- Movement screen and video landing analysis.
- Strength testing (quad, hamstring, glute).
- Progressive exercise plan with the four moves above plus individualized additions.
- Return to sport testing at discharge.
Frequently asked questions
Can I do these on my own?
The exercises are public. Executing them well enough to reduce risk is harder. Most athletes benefit from at least a few sessions with a DPT to dial the form.
What age should we start?
Middle school or high school athletes benefit most. Younger is fine with age appropriate progressions.
Does strength training prevent ACL tears?
Strength alone is not enough. You need the landing and deceleration pieces too.
What if I have already torn my ACL?
A structured return to sport program is critical. Re tear rates are high without one.
How do I know the program is working?
We retest strength and landing mechanics at week six and week twelve. You see the change on video.
