VKBblessures

VKBblessures refers to injuries of the voorste kruisband (VKB), the anterior cruciate ligament in the knee. These injuries are common in athletes and occur when the knee is twisted or hyperextended, often with a rapid change in direction, landing from a jump, or direct contact. The VKB stabilizes anterior movement of the tibia relative to the femur and contributes to rotational stability.

Clinical presentation typically includes a sudden pop or crack, rapid swelling within hours, knee instability or a feeling of the knee giving way, and reduced range of motion. Diagnosis relies on history and physical examination, including tests such as Lachman, anterior drawer, and pivot shift. Magnetic resonance imaging (MRI) confirms a tear and assesses associated injuries; radiographs may detect bone avulsions.

Treatment decisions depend on tear severity, patient activity, and associated injuries. Nonoperative management with structured rehabilitation can be suitable for some partial tears or low-demand individuals. Complete tears or high-demand athletes commonly undergo surgical reconstruction using grafts from the patellar tendon or hamstring. Rehabilitation after surgery involves progressive loading, range-of-motion work, strength training, and neuromuscular exercises. Return to competitive sports is commonly considered around 9 to 12 months postoperatively, depending on recovery milestones and functional testing.

Prognosis is favorable with comprehensive rehabilitation, but risks include graft failure, concomitant meniscal or cartilage injuries, and a longer-term risk of osteoarthritis. Preventive programs focusing on neuromuscular training, proper landing mechanics, and strength conditioning can reduce initial injury risk and improve outcomes.
