Arthroscopic Surgery for Hip Impingement: It Works for Me/in Uncategorized /by mattsmedia43
By: Dean K. Matsuda, MD
In 2003, a colleague asked if I would perform arthroscopic hip surgery on his collegiate athlete daughter. Aware of the inherent technical difficulties in hip arthroscopy, I recommended that he seek the advice of a specialist. Fortunately, my colleague found Thomas G. Sampson, MD, who diagnosed a condition that I had never previously known—femoroacetabular impingement (FAI)—and successfully performed arthroscopic surgery to resolve her painful symptoms.

Realizing that this was uncharted territory for me and my group, I spent several months learning all I could about hip arthroscopy. During my first 6 weeks with Dr. Sampson and James M. Glick, MD, both wonderful mentors, I heard new terms like “cam” and “pincer” and learned much more than just how to safely place an arthroscope in a hip joint. I also learned from other specialists, including Marc J. Philippon, MD; J. W. Thomas Byrd, MD; Marc Safran, MD; and Reinhold Ganz, MD.
My first arthroscopic hip case was a patient with FAI. The patient, an attorney, returned not only to the courtroom but also to kickboxing. During the past 4 years, my practice has evolved from a sports medicine practice into a focused, hip arthroscopy practice; more than 90 percent of my surgical patients have FAI.
Hot topics, good matches
Both hip arthroscopy and FAI are hot topics in orthopaedics. Because FAI commonly occurs in young athletes, arthroscopy is a wonderful match. These patients want to get back in the game and expect minimally invasive surgery to be an option. Hip arthroscopy, at one time viewed as a procedure in need of an indication, has evolved, in great part because of the unique technical challenges presented in the surgical management of FAI.
FAI encompasses a variety of bony dysmorphisms that require individualized surgical variation. My typical patient is a young adult athlete with symptomatic focal cam-pincer FAI. My surgical goals are to treat any internal labral and chondral damage and to relieve ongoing impingement by reshaping the hip joint toward normal nonimpinging anatomy.
I usually perform supine arthroscopic acetabular rim trimming and labral refixation under intermittent traction, and femoral head-neck resection osteoplasty in a semiflexed position without traction, using a two-portal technique. My workhorse portal is a modified midanterior portal. I have developed a novel way of using intermittent fluoroscopic evaluation to obtain a more precise acetabular rim reduction. Arthroscopic dynamic testing ensures that impingement is eliminated in multiple planes.
It worked for me, too!
About 18 months ago, I had arthroscopic surgery on both hips (a month apart), giving me clinical experience from both sides of the scalpel. My surgeon found significant chondral delamination; despite rim trimming, the residual exposed subchondral bone required microfracture chondroplasty. I was pleasantly surprised at the paucity of postoperative pain; my recovery from uneventful ACL reconstructive surgery was much tougher.
Although my left hip has occasional pain, I am able to resume full court basketball, and my right hip is asymptomatic. I am happy with the outcome. I do not see the residual left hip pain as a sign of surgical failure, but as support for my position that patients with FAI should be diagnosed and treated sooner rather than later.
Compared with the classic open surgical hip dislocation procedure with greater trochanteric slide or flip osteotomy, the arthroscopic equivalent offers the following advantages:
- true outpatient surgery
- minimal blood loss
- no trochanteric osteotomy-related complications
- outstanding cosmesis (many patients have difficulty understanding how so much surgery can be done through two small incisions)
- quicker rehabilitation
Patients may begin exercise bicycling 24 hours postoperative; although I urge patients to remain on crutches for 1 to 2 weeks, many walk into my office without crutches at their 1-week visit. I tell my patients to minimize impact activities like running for 12 weeks. Although some patients notice dramatic early improvement in pain, mechanical symptoms, and range of motion, others exhibit a gradual improvement over a period of 1 or even 2 years.
An exciting time
The lay media perceives hip arthroscopy (with some justification) as an inherently glamorous topic; young athletes sidelined with hip pain now have a minimally invasive option to get them back in the game. It behooves us as orthopaedic surgeons to be ready, knowledgeable not only about FAI but also about current treatment options.
Although hip arthroscopy has been around for decades, FAI and some innovative orthopaedic surgeons have transformed this into a procedure that now has a growing list of indications. We are seeing what can technically be done with these arthroscopic procedures; we need further investigation to tell us what actually benefits our patients over the long haul.
From what I’ve seen (and felt) from both sides of the scalpel, I believe that arthroscopic management of FAI will become the treatment standard for most patients. It won’t happen overnight because the procedure is technically challenging and few training venues exist. Complications resulting from improper technique include femoral head osteonecrosis and femoral neck fractures. Underresection can leave residual impingement.
Not all FAI patients are best treated arthroscopically. An open procedure, possibly including a periacetabular osteotomy, may be more suitable for those who have severe acetabular retroversion and/or global impingement. Joint reconstructive surgery may be better for those with significant osteoarthrosis. Many unanswered questions merit future investigation.
Nevertheless, I believe Paul E. Beaule, MD, summed up the future quite well: “What you are doing (comprehensive arthroscopic management) is the future of hip impingement surgery.” My hope is that young, athletic patients will seek early help for their hip pain and will be able to choose a truly minimally invasive option—one that just may make being benched while waiting for an early hip replacement a thing of the (recent) past.

Past ISHA President, Thomas G. Sampson M.D./in News, Uncategorized /by mattsmedia43
Dr. Sampson was a founding member, and the third president of ISHA who is among those involved in the earliest development of hip arthroscopy. He, along with his associate James M. Glick MD developed the lateral approach to hip arthroscopy, devices for hip distraction, and some of the earliest instrumentation, portals and procedures used for hip arthroscopy. Later on he has developed advanced techniques, and in the year 2000 pioneered the eventual migration of hip preservation and its transition from open surgical dislocation to its treatment using hip arthroscopic methods. His latest work involves preservation of nearly all cartilage and labrum, no matter what the abnormal morphology or injury pattern presents, and the treatment of acetabular labro-chondral delamination (FAACD) using a fracture response technique.
