A Year in Review-26

Day 4 already! If you missed Day 1, Day 2 or Day 3 of my 12 hip days of Christmas series featuring 12 top hip papers, you might like to read these also. In the first 2 days we covered a couple of important FAIS papers and yesterday an excellent paper on acetabular dysplasia. Today we continue a theme of joint instability to take a look at one of the first papers to really highlight the issue of instability after hip arthroscopy. Gross instability is likely under-reported in the literature and micro-instability likely under-recognized following hip arthroscopy. Below you'll find an infographic and some key learnings from this paper.

PAPER 4: Gross Instability After Hip Arthroscopy: An Analysis of Case Reports Evaluating Surgical and Patient Factors

Iatrogenic hip instability is increasingly recognised as a cause of persistent pain and disability following hip arthroscopy. Physiotherapists and other rehab professionals often underestimate the potential risk of instability and even frank dislocation following hip arthroscopy, even months after surgery. It concerns me how many patients are prescribed standing or prone through-range hip extension exercises in the early post operative period. The innocuously small portals visible at skin level belie the often dramatic insult that has been imparted on the anterior stability mechanisms of the hip joint.

I have added this paper to my 12 top papers series as it was one of the first that drew together the disparate case studies published (likely the tip of a much large iceberg) and started ringing alarm bells for surgeons. The implications for those providing post-operative care were equally profound. Since this paper was published it seems that the floodgates have begun to open, and a number of recent papers have reported poorer outcomes following surgery with unrepaired versus repaired capsulotomy. The role of post-operative microinstability has now been recognised in many with persistent pain and disability following hip arthroscopy.

Key learnings about instability after hip arthroscopy:

  1. Gross instability (dislocation – most commonly anteriorly) may occur even months after hip arthroscopy.
  2. The risk is likely to be multifactorial including patient, surgical and post operative factors.
  3. Patient risk factors include female gender, acetabular dysplasia and ligamentous laxity.
  4. The strongest surgical factors appear to be an unrepaired capsulotomy and iliopsoas. release, but debridement of the labrum (rather than repair) and acetabular rim trimming may also reduce stability post operatively.
  5. Early and/or excessive hip extension and/or external rotation will increase risk of anterior dislocation.

Like to learn more about assessment and treatment of patients with anterior hip instability?

In this course, you can find detailed information on pathoaetiology, assessment and management of anterior hip pain associated with anterior instability and many other conditions.

Interested in a live workshop on this topic? 

Workshop registration is now open for 2022. If you are in Australia, you might like to attend my face-to-face Brisbane workshops in July 2022. If Brisbane is too far, you might like to join us for an action packed 6 hours (2 x 3 hour blocks) interactive zoom online workshop in May 2022. Both workshops include 3 months access to the online learning course, and the online workshop includes 6 weeks access to recordings. 

I hope you enjoyed the infographic and key learnings from Day 4 of my 12 Top Hip Papers. There are 8 more papers to come, so stay tuned and return to the blog page each day to see what other top papers and infographics I have for you!
