Hip

Hip pain in active patients is often mislocated and under-diagnosed. Evaluation is methodical, and treatment is matched to the source of the symptoms.

Approach to care

Pain felt at the hip can originate in the joint itself, in the surrounding soft tissue, or elsewhere in the kinetic chain. A careful examination distinguishes these before treatment begins.

Non-operative management, including structured rehabilitation, is often the first step. Where surgery is indicated, minimally invasive techniques are used when they suit the diagnosis and the patient.

Recovery planning accounts for the demands the hip has to meet, whether that is a return to sport, to work, or to unrestricted daily activity.

Areas of focus

  • Hip impingement (FAI)
  • Labral injury
  • Hip pain in athletes
  • Soft tissue injury around the hip
  • Hamstring tendon repair
  • Gluteal tendon repair
  • Hip arthritis

Finding the true source of hip pain

Hip pain is one of the more commonly misattributed complaints in orthopedics. Pain in the groin usually reflects the joint itself. Pain on the outside of the hip is more often gluteal tendon or bursal in origin. Pain at the back of the hip may come from the hamstring origin, the pelvis or the lumbar spine.

The evaluation works through those possibilities in order — history, gait, range of motion, provocative testing of the joint and the surrounding tendons, and an assessment of the spine when the pattern suggests it. Radiographs are obtained for nearly everyone; MRI is added when a labral tear, tendon tear or stress injury is suspected and would change management.

  • Groin pain and limited internal rotation — intra-articular hip
  • Lateral pain and difficulty side-lying — gluteal tendon or bursa
  • Deep posterior or sit-bone pain — hamstring origin
  • Radiating or belt-line pain — lumbar spine referral

Non-operative treatment

Most hip conditions are treated first without surgery. Femoroacetabular impingement, gluteal tendinopathy and early arthritis all respond to a well-designed rehabilitation program that restores hip and core strength and changes how the hip is loaded during sport and daily activity.

Injections are used selectively — both to relieve symptoms and, in some cases, diagnostically, since a response to an intra-articular injection helps confirm that the joint itself is the pain generator.

Surgical treatment

When structural injury persists despite appropriate rehabilitation, surgery is discussed. Labral injury with impingement, full-thickness gluteal tendon tears and proximal hamstring tendon tears are the conditions most likely to benefit from operative treatment.

Hamstring and gluteal tendon repair restore the attachment of tendons that rehabilitation alone cannot reattach, and they are procedures often overlooked in patients told their pain is simply bursitis or a chronic strain. Each is planned around the tear pattern, tissue quality and the patient's functional goals.

  • Hip arthroscopy for labral injury and impingement
  • Gluteal tendon repair
  • Proximal hamstring tendon repair
  • Management of hip arthritis and referral when replacement is the right answer

Recovery

Tendon repairs around the hip involve a protected period, often with crutches and defined restrictions, followed by progressive loading. Arthroscopic procedures follow a staged protocol focused on restoring motion before strength.

Protocols are written out and shared with the treating therapist, and return to running or sport is based on strength and control testing rather than time alone.

Common questions

Is my lateral hip pain just bursitis?

Often it is not. Persistent pain on the outside of the hip, especially with weakness or difficulty side-lying, is frequently gluteal tendinopathy or a tendon tear, which is treated differently than bursitis.

Who is a candidate for hip arthroscopy?

Typically a younger, active patient with impingement and labral injury, preserved joint space, and symptoms that persist after a genuine course of rehabilitation.

Can hip pain come from the back?

Yes. Lumbar spine pathology commonly refers to the buttock and posterior hip, which is why the spine is assessed as part of the evaluation.

Do I need to stop running?

Not necessarily. Load is often modified rather than eliminated, and the plan is built to get you back to running with better mechanics.
