Predictors of Outcomes After Hip Arthroscopic Surgery for Femoroacetabular Impingement

Hip arthroscopy for femoroacetabular impingement (FAI) is a surgical procedure aimed at correcting the structural abnormalities of the hip joint that can cause pain and limited motion.

The benefits of hip arthroscopy for FAI have been well established. However, the outcomes of this procedure can vary, and several factors have been identified as potential predictors. These include:

  • Age: Younger patients often have better outcomes due to higher potential for recovery and less advanced joint degeneration.
  • Sex: Some studies report that males have better outcomes than females. Others found female se to be a positive predictor.
  • Body Mass Index (BMI): Higher BMI can be associated with poorer outcomes, possibly due to increased stress on the joint and surgical complications.
  • Preoperative Intra-articular hip injections: Greater reductions in pain with preoperative intra-articular anesthetic injections were found to be associated to better outcomes after FAI surgery, but all available studies contain a high risk of bias.
  • Severity and Duration of Symptoms: Patients with severe or long-standing symptoms might have more advanced joint damage, potentially leading to less favorable outcomes. Patients with chronic pain predicts inferior outcomes from hip arthroscopy for FAI. Patients with back pain negatively influence outcomes.
  • Athletes: Athletes undergoing hip arthroscopy for FAI, predict significant improvement and a high rate of return to sport at the same or greater competition level when compared to preinjury level.
  • Presence of Osteoarthritis: The presence and degree of osteoarthritis in the hip can negatively impact the outcomes of the surgery.
  • Presence of Hip Dysplasia: The presence of hip dysplasia can impact outcomes depending on the severity of the dysplasia. Studies report that patients with borderline hip dysplasia can acheive significant improvement.
  • Hip Joint Morphology: Specific structural characteristics of the hip joint, as identified through imaging studies, can influence surgical outcomes.

  • Extent of Surgical Correction: The amount and type of bone and soft tissue correction performed can impact outcomes.
  • Surgical Technique and Experience of Surgeon: The expertise of the surgeon and the specific techniques used can influence the success of the procedure.

  • Rehabilitation and Physical Therapy Compliance: Effective and consistent postoperative rehabilitation is crucial for successful recovery.
  • Patient’s General Health and Comorbidities: Overall health status and the presence of other medical conditions can affect recovery.

  • Patient Expectations and Mental Health: A patient’s expectations and mental well-being can play a significant role in their perception of the surgery’s success and their postoperative recovery.

It’s important to note that the relationship between these factors and surgical outcomes can be complex. They often interact with each other, and their individual impact can vary from patient to patient. Regular follow-up and personalized management strategies are essential for optimizing outcomes in patients undergoing hip arthroscopy for FAI.
