Knee flexion contractures are common in osteo arthritic patients, having been estimated to occur in up to 60% of patients undergoing total knee arthroplasty (TKA). The definition of a knee flexion contracture is a knee that is unable to fully extend to 0°, either actively or passively.

Contracture of muscle, unspecified site The 2022 edition of ICD-10-CM M62. 40 became effective on October 1, 2021. This is the American ICD-10-CM version of M62.
Flexion contracture deformities, as well as severe varus and valgus deformities of the knee joint, accompany osteoarthritis (OA) or rheumatoid arthritis (RA). Various factors can cause flexion contracture in arthritic knee joints, such as deformities of the ligament, joint capsule, and bone.
A flexion contracture is a bent (flexed) joint that cannot be straightened actively or passively. It is thus a chronic loss of joint motion due to structural changes in muscle, tendons, ligaments, or skin that prevents normal movement of joints. [
(kun-TRAK-cher) A permanent tightening of the muscles, tendons, skin, and nearby tissues that causes the joints to shorten and become very stiff. This prevents normal movement of a joint or other body part. Contractures may be caused by injury, scarring, and nerve damage, or by not using the muscles.
The most common causes of contracture are inactivity and scarring from an injury or burn. People who have other conditions that keep them from moving around are also at higher risk for contracture deformity. For example, people with severe osteoarthritis (OA) or rheumatoid arthritis (RA) often develop contractures.

A contracture occurs when your muscles, tendons, joints, or other tissues tighten or shorten causing a deformity. Contracture symptoms include pain and loss of movement in the joint. If this occurs, you should seek treatment right away. Doctors can treat contractures with medicine, casts, and physical therapy.
Documenting Knee Range of MotionIf a person has 10 degrees of knee hyperextension and 130 degrees of knee flexion, it would be documented as 10-0-130.If a person has a 10 degree contracture and loss of full knee extension with 130 degrees of knee flexion, it would be documented as 0-10-130.
concentricBarre Training Tip: Flexion typically is concentric in the anterior muscles and extension is concetric for the posterior. One exception is in the knee: the quadriceps concentrically contract to extend the knee, while the hamstrings concentircally contract to flex the knee.
The most common contractures observed in dystrophinopathies in the order of frequency are ankle plantar flexion, knee flexion, hip flexion, hip abduction, elbow flexion, and wrist flexion contractures.
