The knee works like a strong but flexible hinge connecting the thigh bone (femur) to the shin bone (tibia).
It also includes the fibula (smaller bone on the side of the leg) and the kneecap (patella), which protects the front of the joint.
Cartilage inside the knee acts as a cushion, allowing smooth movement and preventing the bones from rubbing together.
Ligaments are strong bands of tissue that hold the bones together and keep the knee stable.
Tendons connect the muscles to the bones, enabling the knee to bend, straighten, and move.
Together, these structures make the knee a powerful and stable joint that supports your weight and allows you to walk, run, jump, and move with ease.
Sudden stops or changes in direction (e.g., football, basketball, badminton).
Landing awkwardly from a jump.
Pivoting or twisting the knee while the foot is firmly planted.
Direct impact to the knee, such as a collision or tackle.
-The ligament may stretch, partially tear, or completely rupture, causing pain, swelling, and instability.
-Many injuries are non-contact, meaning they happen without physical collision, often due to body mechanics or poor landing technique.
Purpose: ACL surgery repairs a torn anterior cruciate ligament, which helps keep the knee stable.
Procedure: The damaged ACL is removed and replaced with a new tendon (graft).
Graft Source: The graft is usually taken from the patient’s own hamstring or kneecap tendon, or sometimes from a donor.
The surgeon makes small incisions and uses a camera (arthroscope) to guide the procedure.
Bone tunnels are drilled to position the new tendon correctly.
The graft is then fixed in place to allow healing and transformation into a new ligament.
Post-surgery rehabilitation is essential for full recovery.
Patients undergo physiotherapy for several months to regain strength, movement, and confidence before returning to daily or sports activities. Rehabilitation After ACL Surgery
Most ACL rehabilitation focuses mainly on strength and physical recovery.
However, many patients still struggle with fear of reinjury, fear of movement, and loss of confidence even after regaining strength.
The Structured Psychoeducation for ACLR Rehabilitation program was created to bridge this gap by addressing both the mind and body.
Through simple education, self-reflection, and guided techniques, Structured Psychoeducation for ACLR Rehabilitation helps patients understand their recovery, manage fear, and build confidence step by step.
Knee stiffness or limited motion – difficulty fully bending or straightening the knee.
Persistent pain or swelling – may continue for weeks or months after surgery.
Infection – rare, but possible at the surgical site.
Graft failure or re-tear – the new ligament may stretch or rupture again.
Blood clots (deep vein thrombosis) – can occur in the leg veins after surgery.
Weakness or muscle imbalance – especially in the thigh (quadriceps) or hamstrings.
Numbness around the incision area – due to small nerve irritation.
Arthrofibrosis – excessive scar tissue formation causing stiffness.
Early joint degeneration (osteoarthritis) – possible in long-term cases.
Fear of reinjury and loss of confidence – psychological barriers that can delay full recovery.
