The iWALK crutch is intended for use with below-the-knee-injuries only. An uninjured knee and upper leg are required to provide strength, mobility, and support while using the device. For this reason, we cannot recommend the iWALK crutch for your recovery if your injury is the knee or above.
See below for more information:
iWALK crutch works for these common lower leg injuries
Foot fracture, sprained ankle, broken ankle, Achilles tendon rupture, Achilles tendon injuries, bunions, tibia fracture, fibula fracture, Jones fracture, plantar fasciitis, stress fractures (lower leg), below knee amputation, foot and ankle dislocations, foot ulcers, calf muscle tear, calf muscle strain, gastrocnemius tear, almost any lower leg injury is indicated for use with iWALK crutch. iWALK is also a great way to keep your foot elevated after surgery or significant injury while still having mobility.
iWALK crutch does NOT work for these leg injuries
Any injury to the knee or above. So common conditions like ACL tears, MCL tears, patella conditions, dislocations, and other knee injuries, hamstring tears and strains, groin injuries, piriformis injuries, IT band issues, illiopsoas (hip flexor) conditions, diabetic ulcers where proprioception issues adversely affect balance or any other knee or above upper leg injury will all require another form of crutches or mobility aid.
