Non-operative treatments

Introduction:

In many cases, surgery is not the default first step for femoroacetabular impingement syndrome or labral pathology. Current guidance consistently recommends a structured trial of conservative management before arthroscopy is considered, with a good portion of patients, particularly adolescents, improve enough to avoid surgery altogether.

Activity Modification1:

The first step is relative rest and modification of activities of daily living or sport-specific movements that provoke impingement, particularly deep hip flexion combined with adduction and internal rotation. Patients are counseled to identify and stay within a “safe” rang of motion that avoids symptoms provoking positions while acute symptoms settle typically over the intil 6 weeks.

Pharmacologic Management

Oral analgesia and short courses of NSAIDs are used to control pain during the acute phase, allowing the patient to participate more effectively in physical therapy. This is a symptom-control bridge, not a disease-modifying treatment.

Structured Physical Therapy2-3:

This is the most evidence-supported non-operative intervention and should be delivered as a supervised, progressive program. Recommendations usually suggest 6-12 weeks of physiotherapist-led treatment before surgery is considered, built around several core components:

• Hip- and functional lower-limb strengthening, with particular attention to the deep hip external rotators, abductors, and flexors, since weakness in these muscles is thought to reduce dynamic joint stability.
• Core and lumbo-pelvic stability training, given the close mechanical relationship between pelvic control and hip loading during functional movement.
• Manual therapy techniques, including joint mobilization.
• Movement-pattern retraining, teaching patients to perform daily and athletic movements while minimizing provocative positions.

Randomized trial evidence shows this type of prescribed physiotherapy produces a small-to-medium improvement compared with passive modalities, stretching, or advice alone, though the certainty of this evidence remains low to very low2-3. Importantly, physiotherapy has been shown to be inferior to hip arthroscopy for symptom and functional improvement, but it remains the appropriate first-line approach given its low risk and the meaningful proportion of patients who improve without ever needing surgery4.

Intra-Articular Injections

Image-guided intra-articular hip injections serve a dual diagnostic and therapeutic role:

Diagnostic value. Significant pain relief following an intra-articular injection supports an intra-articular source of pain and helps confirm that imaging findings correlate with the patient's symptoms5. A poor or absent response to a preoperative injection is a recognized predictor of worse surgical outcomes and should prompt reconsideration of the presumed diagnosis before proceeding to arthroscopy6.

Therapeutic value. Evidence for sustained benefit is mixed. Corticosteroid injections can provide short-term relief, but one study found only 37% of patients had significant pain reduction at two weeks and just 6% maintained relief at six weeks meaningfully lower durability than corticosteroid injection for hip osteoarthritis, where the evidence is considerably stronger8. Hyaluronic acid injections have shown more promising therapeutic relief at twelve months in some series, though overall evidence quality remains limited6.
