The adductor muscles are a group of muscles in the medial compartment of the thigh, which are primarily used for bringing the thighs together. There are four primary muscles in this group: the adductor longus, adductor brevis, adductor magnus, and gracilis. These muscles are highly susceptible to strain or injury, especially in athletes who participate in sports such as soccer, basketball, or martial arts. Adductor tenotomy, which involves cutting the origin tendons of the adductor muscles of the thigh, is sometimes performed on children with spastic quadriparesis or cerebral palsy.

The adductor longus is the most proximal tendon among the adductors of the hip joint
The adductor muscles of the hip are a group of muscles in the medial compartment of the thigh. These muscles are responsible for bringing the thighs together, a movement known as adduction. There are four primary muscles in this group: adductor longus, adductor brevis, adductor magnus, and gracilis.
The adductor longus, in particular, is a large, flat muscle that partially covers the adductor brevis and magnus. It forms the medial border of the femoral triangle and provides some medial rotation. The adductor longus originates from the pubis bone of the pelvis and expands into a fan shape, attaching broadly to the linea aspera of the femur. This insertion point is proximal among the adductors, located between the insertion of the adductor magnus and the origin of the vastus medialis muscle, and inferior to the adductor brevis insertion.
The adductor brevis, on the other hand, is a short muscle that lies underneath the adductor longus. The gracilis is the most superficial and medial of the hip adductors, crossing at both the hip and knee joints. It originates from the inferior rami of the pubis and the body of the pubis, attaching to the proximal medial tibia as part of the pes anserine group.
The adductor magnus is the largest muscle in the medial compartment of the thigh and is comprised of two parts: an adductor component and a hamstring component. The adductor portion of the adductor magnus has a similar structure, proximal attachment, and innervation to the hamstring muscles. It runs from the ischial tuberosity to the adductor tubercle on the medial femoral condyle, with fibrous attachments to the femur's supracondylar line.

The gracilis is the most medial of the hip adductors
The gracilis muscle is the most medial and superficial of the hip adductors. It is a long, slender muscle located in the medial (adductor) compartment of the thigh. It is also the weakest of the adductors. The gracilis is the only hip adductor that crosses and acts on two joints: the hip and the knee. It extends from the coxal bone to the tibia, allowing for thigh adduction and flexion, as well as leg flexion and medial (internal) rotation. This movement helps to balance the trunk during activities such as walking.
The gracilis muscle is thin and flat, with a broad top that tapers off as it approaches its insertion point. It arises from the anterior margins of the lower half of the symphysis pubis and the upper half of the pubic arch. Its fibres run vertically downward, ending in a rounded tendon. This tendon passes behind the medial condyle of the femur and curves around the medial condyle of the tibia, inserting into the upper part of the medial surface of the tibia, below the condyle.
The gracilis muscle plays an important role in medial rotation of the leg. When the foot is planted on the ground, the gracilis helps to laterally rotate the femur and pelvis around the tibia, which acts as a fulcrum. This action is crucial for maintaining balance. The gracilis is also involved in thigh adduction, which is particularly evident during horse riding, when it helps the rider to grip the horse.
The gracilis muscle receives most of its vascular supply from the 'artery to the adductors', a branch of the deep femoral artery. This artery enters the gracilis via its lateral surface, approximately one-third away from its origin. The gracilis muscle is commonly used in microsurgery and reconstructive surgery, either as a pedicled flap or as a free microsurgical flap.

Adductor tendinopathy is a common cause of groin pain and injury
The adductor muscles are a group of muscles in the medial compartment of the thigh. They are primarily used for bringing the thighs together, a movement known as adduction. There are four primary muscles in this group: the adductor longus, adductor brevis, adductor magnus, and gracilis. These muscles also function to move the thigh or lower extremity closer to the body's central axis.
Groin pain due to adductor tendinopathy usually develops gradually, making it challenging to pinpoint the exact time of injury. It often starts as a slight discomfort that worsens over time. Physiotherapy is recommended for treating adductor tendinopathy, with active therapy through an exercise programme being superior to a passive treatment approach. Treatment focuses on rest, recovery, and gentle stretching exercises. Strengthening the abdominal core muscles is also advised to support the adductors during activity, along with hip flexor exercises. It is important to tailor the exercises to the athlete's specific sport to avoid recurrence. The recovery timeline can vary, with acute cases resolving within a few weeks, while more chronic cases may take several months before returning to normal, pain-free activities.
To prevent adductor tendinopathy, athletes should engage in a strength and conditioning programme to address factors such as improving muscle strength and coordination while allowing adequate recovery between training sessions. Developing muscular strength and stability around the groin and pelvic areas is crucial, along with muscular flexibility. Regular stretching is recommended, and products like mobility and muscular supports can help alleviate high impacts.

Adductor tenotomy is sometimes performed on children with cerebral palsy
Adductor muscles are a group of muscles in the medial compartment of the thigh that are mostly used for bringing the thighs together. There are four primary muscles in this group: adductor longus, adductor brevis, adductor magnus, and gracilis. These muscles are innervated by the obturator nerve, with the exception of a small part of the adductor magnus, which is innervated by the tibial nerve.
Adductor tenotomy is a surgical procedure that involves cutting the origin tendons of the adductor muscles of the thigh. This procedure is sometimes performed on children with spastic cerebral palsy to prevent hip dislocation and reduce the trend towards lateral displacement of the hip joints. Children with cerebral palsy may present with subluxation or dislocation due to spasticity, which can cause an increased risk of hip dysplasia and dislocation.
The decision to perform adductor tenotomy is based on the migration percentage (MP) measured on preoperative radiographs. The procedure is considered successful if the MP at follow-up is reduced or has increased by less than 10%. The operation has been found to have favourable outcomes in approximately two-thirds of patients.
Adductor tenotomy is often performed as a prophylactic measure to prevent hip dislocation and improve walking ability, posture control, and hip symmetry. It can also facilitate hygiene and provide pain relief for children with cerebral palsy. The procedure is typically performed before the MP reaches 50% and is followed by a period of immobilization and physiotherapy.

The adductor group of muscles generally originates from the pelvis and inserts on the femur
The adductor muscles of the hip are a group of muscles in the medial compartment of the thigh. The adductor group of muscles generally originates from the pelvis and inserts on the femur. The adductors originate on the pubis and ischium bones and insert mainly on the medial posterior surface of the femur. The pectineus is the only adductor muscle that is innervated by the femoral nerve. The obturator nerve innervates the other adductor muscles, except for a small part of the adductor magnus, which is innervated by the tibial nerve.
The adductor muscles of the hip include the adductor longus, adductor brevis, adductor magnus, and gracilis. The adductor longus is a large, flat muscle that partially covers the adductor brevis and magnus. It forms the medial border of the femoral triangle and provides medial rotation. The adductor brevis is a short muscle that lies underneath the adductor longus. The gracilis is the most superficial and medial of the hip adductors. It crosses at both the hip and knee joints and adducts the thigh at the hip, flexing the leg at the knee.
The adductor magnus is the largest and most posterior of the medial thigh compartment muscles. It is also considered the most powerful and complex of the adductor group. The adductor magnus has two portions: the adductor (pubofemoral) and hamstring (ischiocondylar). The adductor segment comprises approximately 70% of the adductor magnus muscle. The adductor and hamstring portions work together to control the pelvis during the gait cycle. The adductor portion also flexes the thigh, while the hamstring portion extends it.
The adductor minimus is often considered a part of the adductor magnus. In about 33% of people, a supernumerary muscle is found between the adductor brevis and adductor minimus. This muscle originates from the upper part of the inferior ramus of the pubis and inserts into the anterior surface of the insertion aponeurosis of the adductor minimus in half of cases.
