What Is a Torn Groin? Causes, Symptoms, and Treatment

A torn groin is a partial or complete tear of one of the muscles or tendons on the inner thigh, the group collectively known as the adductors. These muscles pull your leg inward and stabilize your pelvis during movement, and tearing one produces sharp pain near the crease where your thigh meets your torso. The injury ranges from a mild strain that heals in a couple of weeks to a full rupture that can sideline you for months, and it accounts for a meaningful slice of all sports injuries. The story behind it, from why certain athletes are more vulnerable to what actually works for recovery, is more layered than the “rest and ice” advice most people hear.

The Muscles Involved

Your groin region contains six adductor muscles that fan from the pelvis down to the inner thigh and knee. Any one of these can be injured, though the adductor longus is by far the most common culprit.¹ The adductor longus is a relatively thin structure at its origin. Where it attaches to the pubic bone, it is a blend of about 38% tendon and 62% muscle tissue, and the tendon cross-section narrows rapidly within the first couple of centimeters from that attachment point.² That narrow origin is part of why it tears so easily: a relatively small structure is absorbing forces generated by your entire leg during explosive movements.

The other adductors, including the adductor brevis, adductor magnus, gracilis, pectineus, and obturator externus, can also be strained, though isolated tears of these muscles are less frequently reported. The adductor longus gets the most attention in the medical literature because it is the most commonly torn and, when fully ruptured, can require surgical repair.

How Groin Tears Happen

Most groin tears happen during explosive movements that force the leg outward while the adductor muscles are contracting to pull it inward. Think of a soccer player planting one foot and kicking with the other, a hockey player pushing off in a lateral stride, or a sprinter suddenly changing direction. The injury is most common in sports involving repeated accelerations, decelerations, kicking, and sharp changes of direction.³

The forces involved are substantial. During something as routine as jogging, loads up to eight times your body weight pass through the hip joint; during competitive play those loads can be even greater.⁴ When a sudden eccentric contraction, where the muscle is lengthening while trying to contract, exceeds what the tendon or muscle fibers can tolerate, something gives. Often that is the tendon at its narrow origin on the pubic bone, or the junction where tendon transitions into muscle.

Not all groin tears are acute, dramatic events. Some develop gradually, starting as low-grade irritation that worsens over weeks of continued training. Chronic adductor tendinopathy can eventually progress to a partial tear if a player keeps competing through the pain. These chronic cases tend to be harder to treat than a clean acute tear, partly because the tissue has already undergone degenerative changes by the time the athlete seeks help.

What a Torn Groin Feels Like

With an acute tear, you typically know the exact moment it happens. There is a sudden, sharp pain in the inner thigh or near the pubic bone, sometimes accompanied by an audible pop. Swelling and bruising can develop within the first day or two, and squeezing your legs together against resistance will reproduce the pain. Walking may be uncomfortable, and trying to sprint or kick is often impossible.

Milder strains are more subtle. You might feel a vague tightness or ache in the inner thigh during activity that fades with rest. It is easy to dismiss this as soreness, which is one reason athletes often continue playing and convert a minor strain into something worse. A hallmark sign worth watching for: pain that gets better during warm-up but returns afterward, or pain that worsens specifically with resisted adduction (pushing your knees together against an object). If you notice either pattern, it is worth getting evaluated before pushing through another practice.

Grading the Severity

Groin strains are typically classified on a scale from 0 to 3 based on imaging findings and clinical presentation. The grading matters because it directly dictates how long recovery will take and how aggressively the injury needs to be managed.

• Grade 0–1: Mild strain with minimal fiber disruption. Pain is present but function is mostly preserved. These injuries often heal within two to three weeks with structured rehabilitation.
• Grade 2: A partial tear with clear disruption of some fibers on imaging. More pain, more functional limitation, and a longer recovery of several weeks.
• Grade 3: A complete or near-complete tear. This is the injury that produces severe pain, significant bruising, and an inability to use the leg normally. Recovery stretches into months.

A prospective study tracking male athletes with acute adductor injuries found that those with grade 0–2 tears became pain-free in a median of about 13 days and returned to full training in roughly 18 days. Grade 3 injuries were a different story: pain-free status took a median of 55 days, and full return to team training took about 78 days.⁵ The gap between mild and severe is dramatic, which is why getting an accurate grade early on saves time in the long run.

Who Is Most at Risk

Previous injury is the single most consistent risk factor. In a prospective study of male soccer players, those with a history of prior groin injury had roughly 67% greater odds of sustaining another one.⁶ This is not surprising: scar tissue is less elastic than healthy muscle, and many athletes return to sport before they have fully restored strength and flexibility in the injured area.

Strength imbalances also play a significant role. The same study found that the ratio of adductor to abductor strength in the non-dominant leg was a meaningful predictor; players with a more balanced ratio were less likely to get hurt.⁶ Beyond measurable strength, other risk factors include inadequate warm-up, training volume spikes, and limited hip range of motion. Sports that demand lateral movement and kicking, like soccer, ice hockey, and rugby, carry the highest incidence.

Getting the Right Diagnosis

The groin is one of the trickiest regions in sports medicine to diagnose accurately, because several different structures can produce overlapping pain patterns. A physical exam is the starting point: your clinician will test resisted adduction, palpate the adductor tendons, and assess hip range of motion. But clinical tests alone often cannot distinguish between a pure adductor tear and other sources of groin pain.

MRI is the standard imaging tool for groin injuries. It can distinguish an isolated adductor tendon tear from a partial-thickness tear, injury to the pubic plate, or problems at the shared attachment point where the adductor longus and the rectus abdominis meet.⁷ Ultrasound is sometimes used as a quicker, cheaper alternative and can identify tendon tears in real time, but MRI provides a more complete picture, especially when multiple structures might be involved.

Conditions That Look Like a Groin Tear

One reason groin pain has a reputation for being stubborn is that the initial diagnosis is sometimes wrong. Several conditions can mimic or coexist with an adductor strain, and missing them means treatment targets the wrong problem.

• Athletic pubalgia (sports hernia): Pain at the pubic attachment of the abdominal wall, often called “inguinal-related groin pain” under current terminology.⁸ This is not a true hernia with a visible bulge but a weakness or tear in the lower abdominal muscles or the inguinal canal floor. It shares a lot of real estate with adductor injuries and the two commonly occur together.
• Osteitis pubis: Inflammation of the pubic symphysis, the joint where the two halves of the pelvis meet at the front. MRI studies in soccer players suggest that adductor dysfunction often precedes the development of osteitis pubis, meaning the two conditions are mechanically related rather than independent.⁹
• Hip joint pathology: Labral tears, femoroacetabular impingement, and even femoral neck stress fractures can refer pain to the groin. These are intra-articular problems rather than muscle injuries, and they require different treatment entirely.¹⁰

The overlap between these conditions is so common that many athletes presenting with chronic groin pain turn out to have more than one contributing problem. A thorough workup matters because treating an adductor strain with rest and strengthening will not resolve an underlying labral tear, and vice versa.

Conservative Treatment and Rehabilitation

Most groin tears, especially grade 0–2 injuries, heal without surgery. The initial phase focuses on reducing pain and inflammation: rest from aggravating activities, ice, and sometimes anti-inflammatory medication. Complete immobilization is rarely recommended because early gentle movement helps the healing tissue organize properly.

Once the acute pain settles, rehabilitation shifts to progressive strengthening. The goal is not just to heal the torn fibers but to restore the adductor-to-abductor strength ratio that, when imbalanced, contributed to the injury in the first place. One exercise that has gained strong support in recent years is the Copenhagen adductor exercise, a partner-based or bench-based side plank that loads the adductors eccentrically. A systematic review found that groups using this exercise consistently showed significant increases in eccentric hip adduction strength and in the adductor-to-abductor strength ratio.¹¹

The rehabilitation timeline depends heavily on meeting clinical milestones rather than on counting calendar days. In the prospective cohort mentioned earlier, athletes who met a “clinically pain-free” criteria before returning to sport had a reinjury rate of just 5%, compared to 21% for those who returned before meeting that threshold.⁵ The lesson is straightforward: rushing back before you’ve checked the boxes costs more time than it saves.

Injections and Emerging Therapies

For athletes whose groin pain becomes chronic but who want to avoid surgery, injectable treatments are sometimes considered. Corticosteroid injections have a mixed track record here. Evidence on their effectiveness for adductor-related groin pain is inconclusive, and the relief they provide tends to be temporary, sometimes simply delaying an eventual surgical intervention.¹²

Platelet-rich plasma (PRP) injections have attracted more interest. PRP concentrates growth factors from your own blood and is injected directly into the injured tendon under ultrasound guidance. It has been described in the literature as a treatment for adductor longus tendinopathy among other hip and pelvic conditions.¹³ The evidence is still thin, limited mostly to case reports and small series rather than large randomized trials. PRP is reasonable to discuss with a sports medicine physician if conservative rehab has stalled, but it is not a proven first-line treatment.

When Surgery Is Needed

Surgery is generally reserved for chronic groin pain that has not responded to months of structured rehabilitation, or for complete ruptures in competitive athletes. The most common surgical procedure is adductor tenotomy, which involves releasing the tendon from its attachment to the pubic bone and sometimes reattaching or debriding damaged tissue.

Outcomes from surgical series are generally favorable for athletes willing to commit to post-operative rehabilitation. In one study of chronic groin pain patients who underwent surgery after failing conservative treatment, those who had an adductor tenotomy returned to sport in an average of about 12 weeks.¹⁴ A separate series focusing specifically on adductor tenotomy found that roughly 60% of patients regained or surpassed their pre-injury activity levels, with about 73% rating their outcome as excellent or very satisfactory. Mean improvement in pain was about 87%, and disability scores dropped significantly after the procedure.¹⁵

When the problem involves both the adductors and the lower abdominal wall, surgeons may combine an adductor release with a sports hernia repair. A study of elite athletes who underwent this combined approach found that 97% returned to their previous sport, and 94% returned at their previous level of play, with a mean return-to-play timeline of 12 weeks from surgery. No patient reported weakness or a decrease in running speed or power afterward.¹⁶ Those are impressive numbers, though it is worth noting these were elite athletes with access to intensive post-surgical rehabilitation. Recreational athletes may see a longer timeline.

Can You Prevent Groin Tears?

Prevention programs exist, and the logic behind them is sound: strengthen the adductors, improve hip mobility, correct imbalances, and warm up properly. In practice, the evidence is encouraging but not conclusive. A systematic review with meta-analysis of randomized trials found that groin injury prevention programs did not produce a statistically significant reduction in injuries overall, though the pooled estimate suggested a clinically meaningful reduction of about 19%.¹⁷

The gap between statistical significance and clinical relevance here is likely a sample size issue. Groin injuries are common enough to matter but not so common that prevention trials can easily recruit the thousands of participants needed to detect a modest protective effect. What the data do suggest is that adductor strengthening, and in particular eccentric strengthening exercises like the Copenhagen adductor, is probably beneficial. Many professional soccer and ice hockey teams now incorporate these exercises into their preseason and in-season routines. Even if the evidence does not yet prove the effect definitively, there is very little downside to stronger adductors and better muscle balance.

Groin Injuries in Young Athletes

The picture changes in adolescents and teenagers. Before skeletal maturity, the growth plates (apophyses) where tendons attach to bone are the weakest link in the chain. Instead of tearing a muscle or tendon, a young athlete is more likely to suffer an avulsion fracture, where the tendon pulls a piece of bone away from the pelvis. A review of pelvic avulsion fractures found that the mean age was around 14.5 years, about 77% of patients were male, and the most common injury sites were the anterior inferior iliac spine and the anterior superior iliac spine rather than the adductor origin itself.¹⁸ Most of these injuries heal with conservative management; only a small minority require surgery.

The practical takeaway for parents and coaches is that groin pain in a teenage athlete should not automatically be dismissed as a simple muscle pull. If a young athlete describes a sudden pop during sprinting or kicking, an X-ray or MRI to rule out an avulsion fracture is worthwhile. The treatment is usually rest and gradual return to activity, but failing to identify the fracture can lead to complications or prolonged symptoms.

Sex Differences in Groin Pain

Groin injuries are reported far more frequently in male athletes, and most of the research reflects that skew. But women do tear their adductors, and there is growing recognition that the biomechanics differ between sexes. A study comparing men and women with hip-related groin pain found that the two groups displayed different lower-limb movement patterns during both low-impact and high-impact functional tasks, suggesting that sex may modify how groin pain develops and presents.¹⁹ The authors called for sex-specific analyses in future research, which hints at a broader gap: most groin injury prevention and rehabilitation protocols were designed around male athletes, and it is not clear they transfer directly to female athletes without modification.

For women experiencing persistent groin pain, the differential diagnosis is wider and can include gynecological causes that would not apply to men. A thorough evaluation that considers both musculoskeletal and non-musculoskeletal sources is especially important in this population, because the default assumption of “adductor strain” may be less reliable when the typical risk profile does not fit.
