Abstract
Chronic inner-thigh pain that radiates toward the knee is often blamed on the hip, the back, or a vague groin strain. In many of the patients I examine, the pain generator is the adductor complex: the inner-thigh muscles and the tendons that anchor them to the pubic bone. This educational post explains what those muscles do, what changes when their tendons stop adapting to load, and how chiropractic care helps by restoring pelvic, hip, and lumbar mechanics. Hence, the tendon is no longer asked to do work it cannot tolerate. A familiar clinical pattern, an adult with years of medial thigh pain and no single remembered injury, shows how examination and staged care fit together. At Injury Medical Clinic PA, chiropractic assessment and treatment are combined with massage therapy, physical therapy loading, functional wellness, and internal medicine oversight from Dr. Maria Guadalupe Cardenas, MD. The goal is not one technique. It is a plan that reduces painful overload, rebuilds tendon capacity, and lowers the chance that the same pattern returns.
What the Adductor Muscles Do
The adductors are the inner-thigh muscle group. Their shared action is hip adduction: they draw the thigh toward the midline. That textbook action understates what they do in everyday life. They also steady the pelvis on the stance leg, help control the trunk over the hip, and absorb force when a person cuts, kicks, skates, climbs stairs, or shifts weight from one foot to the other (Jeno & Schindler, 2023; Thorborg, 2023).
Five muscles make up the usual group:
- Adductor longus is the long, fan-shaped muscle most often involved in groin pain. It arises from the body of the pubis and runs to the middle third of the femur. It adducts the thigh and assists flexion.
- Adductor brevis lies deeper and is shorter, also arising from the pubis and inserting on the femur, and it contributes to adduction and stabilization.
- Adductor magnus is the largest. Its adductor portion comes from the inferior pubic and ischial rami. Its hamstring portion comes from the ischial tuberosity and extends the hip. Although it is a large muscle, its value lies in the range and control it gives the thigh, not bulk alone (Jeno & Schindler, 2023).
- Pectineus is a flat muscle at the top of the inner thigh that flexes, adducts, and medially rotates the hip.
- Gracilis is the long strap from the pubis that crosses the knee. It adducts the thigh and helps flex and medially rotate the leg, which is why gracilis-related pain can be felt toward the knee.
All of these muscles, except the hamstring portion of adductor magnus, originate from the pubic region. Their tendons crowd onto a small bony footprint. That shared insertion is a high-stress zone. In the Doha agreement on groin pain in athletes, adductor-related groin pain is a defined clinical entity: pain in the adductor region, tenderness at the adductor insertion, and pain reproduced by resisted adduction (Weir et al., 2015).
In clinic, I describe the adductors as midline stabilizers as much as “pulling” muscles. On Health Coach Clinic, I have written that they provide torque that brings the lower limb inward during walking and help keep the trunk steady (Jimenez, 2024). If the gluteals, deep hip rotators, or abdominal wall are not sharing load, the adductors are recruited as backup stabilizers. They are built for short, powerful work. They are not built to hold a tilted pelvis together for hours.
Adductor forces in change-of-direction sport are often higher than people expect. In young soccer players, planted-foot cutting can load the adductors more than a short pass (Thorborg, 2023). The same principle shows up outside sport. A worker who repeatedly steps sideways, a runner who increases mileage, or a person who sits most of the day and then trains hard on the weekend can exceed tendon capacity without a single dramatic tear.
What Happens When Tendinopathy Affects the Adductors
An acute adductor strain is a muscle or musculotendinous tear, often during a strong contraction while the muscle is lengthening. Adductor tendinopathy is different. It is a load-related tendon problem. Pain may build over weeks or years. There may be no pop, no bruise, and no day the person can point to.
In practice, the pattern is recognizable. Patients report groin or medial-thigh tenderness, pain when the legs are pressed together, stiffness after sitting, and trouble with stretching that gives only temporary relief. They often think the problem is the hip. Palpation and resisted adduction show that the adductors are the painful structure (Jimenez, 2022; Jimenez, 2024). Pain is often sharpest where the tendon meets the pubic bone and can travel down the medial thigh toward the knee, especially when gracilis is involved.
Modern tendon research moved the label from “tendinitis” to “tendinopathy” because chronic tendon pain is not mainly an inflammatory disease. Cook and Purdam described a continuum: a reactive tendon that thickens after sudden overload, a tendon in disrepair with matrix breakdown, and a degenerative tendon with disorganized collagen, fewer healthy tenocytes, and neovascular ingrowth (Cook & Purdam, 2009). Pain is linked to local chemical signals and nerve ingrowth, not simply to swelling (Millar et al., 2021; Scott et al., 2015).
When that process affects the adductors, several things happen at once.
- The tendon loses load capacity. The same step, cut, or sit-to-stand that used to be routine now exceeds what the insertion can tolerate.
- The muscle guards. Patients often cannot fully contract or lengthen the adductors without pain, so strength drops and the opposite hip and the lumbar spine compensate.
- The pubic enthesis becomes a pain generator. Direct pressure on the tendon as it meets the pubic bone reproduces the familiar ache.
- Trigger points and referred pain muddy the picture. Active myofascial trigger points in adductor longus and adductor magnus commonly refer into the groin and medial thigh. Patients then describe “groin pain” when the irritable tissue is in the inner thigh (Jimenez, 2022).
- Nearby structures get blamed. Because the pain sits in the groin and can travel down the thigh, it is sometimes treated as sciatica. Obturator-nerve irritation and lumbar referral can coexist with adductor pain, but they are not the same diagnosis.
Risk factors I look for match what the literature and the clinic both show: a sudden jump in training, repeated change of direction, incomplete warm-up, fatigue, strength imbalance between adductors and abductors, a pelvic asymmetry that changes gait, weak abdominal control, and age-related tendon change (Kiel & Kaiser, 2024; McHugh et al., 2023; Thorborg, 2023). Complete rest is not the answer. An unloaded tendon loses structure, and the surrounding muscle weakens, so the next return to activity loads a less capable tendon.
A Familiar Clinical Pattern
A 35-year-old man sat across from me with eight years of intermittent aching over the medial right thigh. The ache radiated toward the knee. He could not recall a fall, a tackle, or a single sports injury. That history usually points to accumulated microtrauma rather than one tear.
Palpation told the local story. Tenderness increased as I traced the adductor longus from the muscle belly to the tendon and was sharpest where the tendon anchors on the pubic bone. Pressure along the superior pubic ramus worsened it. Resisted adduction, asking him to pull the leg inward against my hand, reproduced the same pain. That combination- adductor-region pain, insertion tenderness, and pain on resisted adduction- is the clinical definition of adductor-related groin pain (Weir et al., 2015).
The exam does not stop at the tendon. I also screen the lumbar spine, sacroiliac joints, hip rotation, abdominal wall, and gait, because pubic, inguinal, iliopsoas, and hip-joint problems can mimic or travel with adductor pain (Weir et al., 2015). Imaging, under medical oversight, is added when the history suggests a tear, a bony stress injury, or a hip-joint source. Most long-standing adductor-related pain can be classified at the bedside.
How Chiropractic Care Helps
Chiropractic care does not “heal collagen” by itself. The tendon remodels when it is loaded in a way it can tolerate. Chiropractic care changes the mechanical environment that keeps overloading the tendon, the protective muscle tone that blocks a clean contraction, and the movement options at the hip and pelvis so rehabilitation can actually be performed.
Pelvic and sacroiliac mechanics
An asymmetrically rotated or tilted pelvis changes the resting length of the adductors. If one innominate sits in a position that lengthens the adductor origin relative to its insertion, the tendon sees a constant low-grade stretch plus every step of gait. Restoring sacroiliac motion, and checking whether an apparent leg-length difference comes from the pelvis rather than the bones, removes a driver I see repeatedly in chronic cases. Adjustments here are specific and comfortable. The goal is symmetrical load, not forcing a painful groin.
Chronic joint and soft-tissue conditions around the pelvis often predate the acute groin complaint. The adductors, abdominal wall, and iliopsoas share load across the pubic region. When one group is stiff or weak, the others take extra work (Jimenez, 2023).
Lumbar motion and adductor nerve supply
The obturator nerve supplies the adductor muscles mainly from the L2, L3, and L4 roots, with the femoral nerve often supplying the pectineus. Restricted lumbar segments and protective paraspinal tone can change how those muscles fire. Patients describe the thigh as “not listening,” or as aching after sitting. Lumbar chiropractic adjustment and mobilization restore segmental motion and reduce guarding so the adductors can be trained instead of only stretched. This is also why I don’t accept a sciatica label until I’ve completed both the lumbar and adductor exams.
Hip mobility without compressing the tendon
Restricted hip rotation makes the adductors compensate during gait and squatting. Mobilization of the hip, when the joint itself is the stiff segment, reduces that compensation. Aggressive adductor stretching is different. In a painful insertional tendon, long end-range stretches can irritate the enthesis. Early on I prefer gentle capsular mobility and, later, controlled lengthening under load, rather than hanging in a groin stretch.
Muscle-energy technique and soft-tissue work
Muscle-energy technique uses a gentle patient contraction against a controlled barrier, then a short relaxation, to improve muscle length and joint motion. In adductor strain and chronic groin guarding, I use it to reduce tension, improve flexibility, and make the hip easier to move before strengthening starts (Jimenez, 2024). A systematic review of muscle-energy techniques found improvements in pain and range in symptomatic musculoskeletal conditions. However, the trials are heterogeneous, and this is an adjunct, not a stand-alone cure (Thomas et al., 2019).
Instrument-assisted soft-tissue work and myofascial release address the muscle belly and the musculotendinous junction, where strain and trigger points concentrate (Jimenez, 2022). The aim is to reduce hypertonicity and improve sliding between the adductor longus, gracilis, and medial hamstrings so a stuck muscle doesn’t yank the tendon. Soft-tissue work is paired with activation. Releasing a muscle and sending the person home without a strength plan tends to fade within days.
Making the rehabilitation load possible
The treatment with the best evidence for long-standing adductor-related groin pain is active exercise, not passive care alone. In a randomized trial, athletes who did supervised active training returned to sport more often than athletes treated with passive modalities (Hölmich et al., 1999). Current clinical guidance keeps that principle: progressive strength training and sport-specific loading, moving from structural isolation of the adductors to functional integration with the trunk and the rest of the hip (Thorborg, 2023).
Chiropractic care fits in front of and beside that loading. A patient who cannot stand evenly, who cannot rotate the hip without lumbar substitution, or who flinches at the first isometric squeeze will not complete a loading program. Restoring motion and reducing protective tone creates the window in which you can dose exercise.

How Chiropractic Care Combines With Other Nonsurgical Treatment
I do not treat adductor tendinopathy with adjustments alone. The tendon needs load. The muscle needs both release and strength. The person needs a recovery environment that supports remodeling. Those jobs belong to different parts of the same plan.
Physical therapy and graded loading
Physical therapy carries the tendon-capacity work. A typical sequence, matched to pain and function rather than to a fixed calendar, looks like this.
- Early phase: pain-limited isometrics, such as a ball or pillow squeeze between the knees, held long enough to settle symptoms. Isometric loading can reduce tendon pain and serves as a useful bridge to heavier work (Rio et al., 2015).
- Strength phase: slow concentric and eccentric adduction, side-lying adduction, band or cable adduction, and Copenhagen adduction progressions. Eight weeks of Copenhagen adduction training increased eccentric hip-adduction strength by about 36 percent in sub-elite soccer players (Ishøi et al., 2016). A simple adductor strengthening program also reduced groin problems in male football players (Harøy et al., 2019).
- Integration phase: squats, lateral lunges, trunk control, single-leg balance, and then the actual task that hurt, whether that is cutting, kicking, or a work movement.
In this phase, chiropractic visits check that the pelvis and lumbar spine aren’t reintroducing the asymmetry the exercises are trying to correct. If pain spikes, we change dose, not the diagnosis, unless a new exam finding appears.
Massage therapy
Massage therapy is most useful on the muscle and fascia around the tendon, not as deep pressure directly on an irritable pubic insertion. In this condition, I use it to reduce adductor and medial-hamstring guarding, improve tissue glide, and settle trigger points that refer into the groin (Jimenez, 2022). Massage after a loading session can limit next-day stiffness. Massage alone does not rebuild the tendon. The two are scheduled together so the tissue is calmer when the patient practices the exercise.
Functional wellness
Tendon remodeling is a mechanical process with a metabolic cost. Sleep loss, low protein intake, low vitamin D, and poor glycemic control do not cause adductor tendinopathy on their own, but they narrow the margin for repair. At Health Coach Clinic, functional medicine looks past the isolated symptom: history, lifestyle, and, when indicated, laboratory work to show whether recovery inputs are in place (Health Coach Clinic, n.d.). This diagnosis usually means protein distribution across the day, vitamin C as a cofactor for collagen synthesis, vitamin D repletion if deficient, and attention to body mass and training load. These are supports for the loading program, not substitutes for it.
Medical oversight and selective procedures
Dr. Maria Guadalupe Cardenas, MD, board-certified in internal medicine (NPI 1164426749, Texas license J2933), provides medical oversight for differential diagnosis, imaging decisions, comorbidity management, and any procedure covered by medical protocols. Ultrasound can show tendon thickening, cortical irregularity, and neovascularity, and can guide an injection if one is chosen. MRI is reserved for suspected partial tear, osteitis pubis, or hip-joint disease.
When used, a tendon-sheath or peritendinous injection is a pain-modulating tool. It does not remodel collagen. In a selected patient with years of focal insertional pain, it can open a short window for isometrics and pelvic retraining. It is not the plan. Discuss shockwave therapy and platelet-rich plasma only after a real trial of combined loading and manual care, with shared decision-making about the mixed evidence.
What I Watch for in Follow-Up
Chronic adductor cases often hide an upstream driver. Pelvic asymmetry, limited hip rotation, or lumbar stiffness keeps reloading the tendon until you address those. Patients do better when the stages are explicit: settle pain, restore motion, load the tendon, then return to the task that failed.
Education changes adherence. Once a patient understands that pain in a chronic tendon is sensitivity more than new damage, and that load is the medicine, they stop oscillating between total rest and a weekend of overdoing it. I recheck resisted adduction, insertion tenderness, single-leg control, and the movement that originally hurt. Return toward activity is based on those findings, not on a calendar promise. Many athletic cases improve across 6 to 12 weeks when loading is consistent. Eight-year histories take longer, and some need a maintenance plan rather than a cure date.
Closing
Adductor tendinopathy is a capacity problem at a small pubic attachment, made worse when the pelvis, hip, and lumbar spine ask that attachment to stabilize a movement it cannot tolerate. Chiropractic care helps by restoring that mechanical environment, reducing guarding with adjustments, muscle-energy techniques, and soft-tissue work, and enabling a real loading program. Massage therapy calms the muscle around the tendon. Physical therapy rebuilds strength, with Copenhagen-style adduction and heavy-slow work carrying the best evidence. Functional wellness supports the recovery inputs the tendon needs to remodel. Under Dr. Cardenas’s medical oversight, imaging and procedures stay selective.
That is the model we use at Injury Medical Clinic PA in El Paso: chiropractic care as part of a staged, nonsurgical plan, specific to the person in front of us, and honest about what each piece can and cannot do.
