  • Heart-warming hip preservation

    • Authors: Villar R.
      Abstract: There is something incredibly heart-warming about attending the annual ISHA meeting, this year in Chile’s Santiago. It happens to me each time. I was trying to work out why that might be, being heart-warmed, that is. Was it the coming together of like-minded colleagues—well, friends actually—from around the world, bound by a common interest' Was it the realization that younger blood is now shining through and the field of hip preservation is, at long last, secure' Or, was it the astonishment I felt when I visited a brilliant poster section that had more than 100 papers displayed, each with a message that would improve patient care, each from a unit of considerable professional standing'

  • What the papers say

    • Authors: Malviya A.
      Abstract: The Journal of Hip Preservation Surgery (JHPS) is not the only place where work in the field of hip preservation may be published. Although our aim is to offer the best of the best, we continue to be fascinated by work that finds its way into journals other than our own. There is much to learn from it so JHPS has selected six recent and topical subjects for those who seek a summary of what is taking place in our ever-fascinating world of hip preservation. What you see here are the mildly edited abstracts of the original articles, to give them what JHPS hopes is a more readable feel. If you are pushed for time, what follows should take you no more than 10 min to read. So here goes …

  • Preoperative planning for redirective, periacetabular osteotomies

    • Authors: Albers C; Rogers P, Wambeek N, et al.
      Abstract: Redirective, periacetabular osteotomies (PAO) represent a group of surgical procedures for treatment of developmental dysplasia of the hip (DDH) in skeletally mature and immature patients. The ultimate goal of all procedures is to reduce symptoms, improve function and delay or prevent progression of osteoarthritis. During the last two decades, the understanding of the underlying pathomechanisms has continuously evolved. This is mainly attributable to the development of the femoroacetabular impingement concept that has increased the awareness of the underlying three-dimensional complexity associated with DDH. With increasing knowledge about the pathobiomechanics of dysplastic hips, diagnostic tools have improved allowing for sophisticated preoperative analyses of the morphological and pathobiomechanical features, and early recognition of degenerative changes, which may alter the long-term outcome. As redirective, PAO are technically demanding procedures, preoperative planning is crucial to avoid intraoperative obstacles and to sufficiently address the patient-specific deformity. Although conventional radiography has been used for decades, it has not lost its primary role in the diagnostic work-up of patients with DDH. Furthermore, an increasing number of modern imaging techniques exists allowing for assessment of early cartilage degeneration (biochemical magnetic resonance imaging) as well as 3D planning and computer-based virtual treatment simulation of PAO. This article reviews the literature with regard to the current concepts of imaging of DDH, preoperative planning and treatment recommendations for redirective, PAO.

  • Results of hip arthroscopy in patients with MRI diagnosis of subchondral
           cysts—a case series

    • Authors: Hartigan D; Perets I, Yuen L, et al.
      Abstract: The aim of this article is to examine the results of arthroscopic management of patients with labral pathology who have preoperative magnetic resonance images (MRIs) demonstrating subchondral cysts. This institution’s database was searched for patients who underwent hip arthroscopy and had subchondral cysts on MRI and >2-year follow-up. Exclusion criteria included previous hip surgery, Tönnis grade >1, inflammatory arthritis, Perthes, slipped capital femoral epiphysis or abductor repair. Patient-reported outcome (PRO) scores including visual analog scale, modified Harris hip score (mHHS), non-arthritic hip score and hip outcome score sports-specific subscale (HOS-SSS) were gathered preoperatively, at 3 months, and annually thereafter. The change in PRO scores was compared with the minimally clinical important difference (MCID) to quantify improvement. Sixty-nine patients were eligible for this study, of which 65 (94%) had >2-year follow-up. All PROs were significantly improved at latest follow-up (P < 0.001). Mean patient satisfaction was 7.2. There was no correlation between Outerbridge grade III or IV cartilage damage noted during arthroscopy and subchondral femoral and acetabular cysts noted on MRI. Seventeen patients required reoperation [13 total hip arthroplasty (THAs) and 4 revision arthroscopies]. Patients with femoral subchondral cysts converted to THA 36% of the time. MCIDs for mHHS and HOS-SSS were surpassed by 63% and 68% of patients, respectively. Hip arthroscopies performed on patients with subchondral cysts present on preoperative MRI should be approached with caution. The rate of conversion to hip arthroplasty appears to be higher than that reported in the literature for patients who undergo arthroscopy without preoperative subchondral cysts. For patients who did not require hip arthroplasty or revision arthroscopy, patients demonstrated significant improvement in symptoms compared with the preoperative state.

  • How to address ischiofemoral impingement' Treatment algorithm and
           review of the literature

    • Authors: Gollwitzer H; Banke I, Schauwecker J, et al.
      Abstract: Ischiofemoral impingement (IFI) is a rare cause of hip pain defined by a narrowing of the space between the lateral aspect of the os ischium and the lesser trochanter of the femur. Several underlying anatomic, functional and iatrogenic pathologies have been identified for symptomatic IFI in native hip joints and after total hip arthroplasty. Clinical symptoms vary but most commonly consist of pain of the lower buttock and groin including the inner thigh, and a snapping or clunking phenomenon is often reported. Symptoms may be provoked by a combined extension, adduction and external rotation during physical examination and during long-stride walking. Radiographs of the pelvis and an axial or false-profile-view of the hip as well as magnetic resonance imaging (MRI)-scans should be obtained to strengthen the diagnosis. On MRI, the quadratus femoris muscle signal and the space confined by the anatomic structures surrounding the muscle, the quadratus femoris space, are to be assessed. Targeted infiltration of the muscle can be helpful both diagnostically and therapeutically. The literature on differential diagnoses and treatment options for IFI is limited; therapeutic suggestions are offered only in case reports and series. With this work, we aim to give a systematic approach to the non-surgical and surgical treatment options for IFI based upon the current literature and the authors’ personal experience.

  • Technical particularities of joint preserving hip surgery in osteopetrosis

    • Authors: Ganz R; Grappiolo G, Mast J, et al.
      Abstract: Proximal femoral fracture and coxarthrosis are the most common orthopaedic problems of osteopetrosis. Fracture fixation is difficult and one-third fail, with total hip replacement as the final solution. There is little reported experience about how to deal with this particular type of bone and what has been published to date is surprisingly non-specific. Corrective osteotomies are mainly undertaken in children for non-union of a fractured femoral neck and/or for coxa vara. However, any information about technical problems and solutions is scarce and barely instructive. Osteotomy experience for osteopetrosis in youngsters and young adults has not been reported. Osteopetrosis bone is characterized by a small tolerance for displacement and by the high friction experienced when penetrating instruments and implants are used. This article describes the risks of hip surgery in the presence of osteopetrosis and also discusses osteotomies around the hip and how to limit any related complications. Four patients, who underwent different types of hip preservation procedure, have been used to illustrate the difficulties that can be encountered. The article also suggests ways to make osteotomies feasible in osteopetrosis bone, even in adults.

  • Hip dysplasia in wrestlers: three lessons learned

    • Authors: Byrd J; Clohisy J, Kim Y, et al.
      Abstract: Hip problems due to dysplasia are commonly associated with female athletes in sports demanding supraphysiologic motion, such as ballet, gymnastics and figure skating. However, hip problems are rarely mentioned among wrestlers, a male sport in which flexibility is advantageous. Dysplasia may have a mostly unrecognized prevalence among wrestlers that can lead to problems and benefit from reorientation periacetabular osteotomy (PAO). Study design in this research is Level 4 evidence case reports. Three consecutive intercollegiate wrestlers ages 20, 21 and 22 years underwent PAO for dysplasia and are reported. Two underwent concomitant arthroscopy. Each returned successfully to intercollegiate wrestling at 6, 8 and 11 months. There were no complications. This work concludes that dysplasia has an unknown but mostly unrecognized prevalence among wrestlers. With proper recognition and treatment with PAO, there is a reasonable expectation that they could return to wrestling.

  • Early recovery after hip arthroscopy for femoroacetabular impingement
           syndrome: a prospective, observational study

    • Authors: Cunningham D; Lewis B, Hutyra C, et al.
      Abstract: The early post-operative course after hip arthroscopy for femoroacetabular impingement syndrome has not been thoroughly characterized or correlated to factors that may influence recovery. The aim of this study was to report on early pain, function and attitudes towards rehabilitation and to determine predictors of early recovery after hip arthroscopy. Sixty-two patients reported pre-operative pain, iHOT-12 (hip functional score), psychological status and other baseline characteristics. Pain, iHOT-12, hip flexion and several other outcomes were measured through 6 weeks post-operative. Baseline characteristics were correlated with outcomes using univariate and multivariable models. Pain relief started on post-operative day 1 and consistently improved throughout the 6 weeks of follow-up. The average patient’s pain was reduced from a pre-operative level of 5/10 to 2/10 by 6 weeks post-operative. Similarly, iHOT-12 improved from 33/100 to 57/100 whereas hip flexion increased by 9° by 6 weeks post-operative. At 2 weeks post-operative, pre-operative anti-inflammatory usage was associated with greater improvement in pain and swelling; pre-operative opioid usage with poorer patient-reported helpfulness of and adherence to rehabilitation; and higher ASA (American Society of Anesthesiologists) score and lower procedure time with improvement of the pre-operative pain complaint. At 6 weeks, greater depression was associated with lower post-operative pain reduction but greater pre-operative pain complaint improvement. Continuous passive motion usage was associated with increased hip flexion. Pain improved from pre-operative by Day 1 after hip arthroscopy, and early functional improvements were seen by 6 weeks post-operative. Pre-operative anti-inflammatory and opioid usage, depression, race, ASA score, procedure time and continuous passive motion usage were significantly associated with study outcomes.

  • Does duration of symptoms affect clinical outcome after hip arthroscopy
           for labral tears' Analysis of prospectively collected outcomes with
           minimum 2-year follow-up

    • Authors: Dierckman B; Ni J, Hohn E, et al.
      Abstract: Limited research exists on the possible association between duration of symptoms and clinical outcomes following hip arthroscopy for labral tears. The purpose of this study was to evaluate whether duration of symptoms affected clinical and patient-reported outcome (PRO) scores following hip arthroscopy for labral tears. From 2008 to 2011, data were collected prospectively on all patients undergoing primary hip arthroscopy for labral tears. Workers’ compensation cases, dysplasia cases and patients with previous ipsilateral hip surgeries were excluded. A total of 738 patients were identified with a minimum of 2-year follow-up, and clinical and PRO data were available for 680 patients. Uni- and multivariate analyses were performed to determine the relationship between duration of symptoms along with other variables and PROs. Overall, patients experienced significant improvements in all clinical and PRO scores. Results of univariate analysis revealed that all PROs were negatively associated with increasing Log10 months of symptoms as were pain and satisfaction scores. During multivariate analyses, increasing Log10 months of symptoms, age, body mass index and trauma were all negatively associated with PROs (P  < 0.05). Our study demonstrates that clinical and PRO scores were negatively associated with increasing duration of symptoms prior to hip arthroscopy for treatment of labral tears. Although this implies that delay in treatment may adversely affect outcome, conservative treatment remains the gold standard first line of treatment. Surgeons should incorporate this information into their treatment algorithm to maximize patient outcomes following treatment for labral tears. Level of evidence: Level IV, prospective case series.

  • Revision hip arthroscopy: findings and outcomes

    • Authors: Gwathmey F; Jones K, Thomas Byrd J.
      Abstract: The purpose of this study is to report on the operative findings and the outcomes of revision hip arthroscopy. All hip arthroscopy cases are prospectively assessed with a modified Harris Hip Score (mHHS) preoperatively and postoperatively. This study consists of 190 consecutive hips (186 patients) who underwent revision arthroscopy with minimum 2-year follow-up. There were 69 males and 117 females with a mean age of 32.7 (14–64). The mean time from index to revision procedure was 24.5 months (3–146). Common diagnoses included labral tears (102) and unaddressed or residual femoroacetabular impingement (FAI) (49 cam, 11 pincer, and 20 combined). In addition to FAI correction, there were 82 labral debridements, 28 repairs/refixations, and 6 excisions of labral calcifications. Ninety-three underwent various amounts of synovectomy and 21 underwent iliopsoas release/debridement. At a mean follow-up of 46.9 months, 84.5% of patients reported symptomatic improvement. Twenty patients underwent subsequent surgery at mean of 51 months (11 repeat arthroscopy and 9 THA). Among 166 patients who had no further surgery, the mHHS had improved 27.1.8 points from a preoperative mean of 54.5 to 81.6. Patients who underwent treatment of FAI demonstrated a mean mHHS improvement of 25.7 points. Complications included two cases of transient pudendal neurapraxia, one case of transient quadriceps weakness, one case of retroperitoneal extravasation, and one case of perioperative myocardial infarction. In conclusion, for properly selected patients with persistent or recurrent symptoms following previous hip arthroscopy, revision surgery can result in favorable outcomes with an acceptably low complication rate.
