Patient-Reported Outcomes Are Similar in the First 2 Years After Staged Versus Combined Hip Arthroscopy and Periacetabular Osteotomy for Hip Dysplasia.

PURPOSE: To compare early patient-reported outcomes after staged versus combined hip arthroscopy and periacetabular osteotomy for hip dysplasia. METHODS: A prospective database was retrospectively reviewed to identify patients that underwent combined or staged hip arthroscopy and periacetabular osteotomy (PAO) from 2012 to 2020. Patients were excluded if they were >40 years of age, had prior ipsilateral hip surgery, or did not have at least 12-24 months of postoperative patient-reported outcome (PRO) data. PROs included the Hip Outcomes Score (HOS) Activities of Daily Living (ADL) and Sports Subscale (SS), Non-Arthritic Hip Score (NAHS), and the Modified Harris Hip Score (mHHS). Paired t-tests were used to compare preoperative to postoperative scores for both groups. Outcomes were compared using linear regression adjusted for baseline characteristics, including age, obesity, cartilage damage, acetabular index, and procedure timing (early vs late practice). RESULTS: Sixty-two hips were included in this analysis (39 combined, 23 staged). The average length of follow-up was similar between the combined and staged groups (20.8 vs 19.6 months; P = .192). Both groups reported significant improvements in PROs at final follow up compared to preoperative scores (P < .05 for all). There were no significant differences in HOS-ADL, HOS-SS, NAHS, or mHHS scores between groups preoperatively or at 3, 6, or 12 months postoperatively (P > .05 for all). There was no significant difference in PROs between the combined and staged groups at the final postoperative time point: HOS-ADL (84.5 vs 84.3; P = .77), HOS-SS (76.0 vs 79.2; P = .68), NAHS (82.2 vs 84.5; P = .79), and mHHS (71.0 vs 71.0, P = .75), respectively. CONCLUSIONS: Staged hip arthroscopy and PAO for hip dysplasia leads to similar PROs at 12-24 months compared to combined procedures. This suggests that with careful and informed patient selection, staging these procedures is an acceptable option for these patients and does not change early outcomes. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Congenital Absence of the Patellar Tendon: A Report of 2 Cases.

CASE: Isolated unilateral congenital patellar tendon absence is a rare condition that has not been well described. We report on 2 patients with congenital patellar tendon absence that underwent soft-tissue reconstruction of their patellar tendon. We present the clinical and radiographic features, surgical management with both single-stage and multistage approaches, and postoperative outcomes for the treatment of this condition. CONCLUSION: Soft-tissue reconstruction of the patellar tendon led to satisfactory outcomes, providing active knee extension and improved ambulation in both cases. In cases of significant superior migration, multiple procedures may be required to mobilize the patella to an appropriate position.

What patient factors and Patient-Reported Outcomes Measurement Information System domains are associated with worse pain coping in pediatric orthopaedic patients in the United States?

We sought to better understand the relationship between Patient-Reported Outcomes Measurement Information System (PROMIS) mobility, pain interference (PI) and depressive symptoms scores, as well as determine what patient factors and PROMIS domains were associated with worse pain coping (PROMIS PI), in a pediatric orthopaedic population. Between 27 August 2015 and 30 April 2019, new pediatric orthopaedic patients 18 years or younger (or their guardians as a proxy) were asked to complete PROMIS mobility, PI and depressive symptoms domains at an academic medical center pediatric orthopaedic clinic. Pearson correlation coefficients (r) were calculated between each PROMIS domain. Linear multivariate regression analysis was used to determine patient characteristics and PROMIS domains associated with presenting PROMIS PI scores. There was a strong-moderate correlation between PROMIS mobility and PI (r = -0.66, P < 0.001), while the correlation between PROMIS mobility and depressive symptoms was moderate-poor (r = -0.38, P < 0.001). There was a moderate correlation between PROMIS depressive symptoms and PI (r = 0.54, P < 0.001). In multivariate linear regression analysis, female gender (ß = 0.82, P < 0.001), self-reported black race (ß = 0.94, P < 0.001), Medicaid insurance (ß = 0.82, P < 0.001) and worsening depressive symptoms (ß = 0.33, P < 0.001) were associated with worse pain coping mechanisms, while increasing mobility (ß = -0.47, P < 0.001) was associated with better pain coping mechanisms. Poor mobility and worse depressive symptoms are associated with worse pain coping mechanisms. Additionally, Medicaid insurance status, black race and female gender are also associated with worse physical limitations secondary to pain.

Incidence and Complications of Open Hip Preservation Surgery: An ABOS Database Review.

Hip preservation surgery encompasses various surgical procedures that have the goal of decreasing the progression of osteoarthritis, preserving normal hip function, and delaying the need for arthroplasty. These procedures can encompass arthroscopic, open, and combined techniques. This study investigated the trends and complications associated with open hip preservation surgery performed by candidates undergoing Part II of the American Board of Orthopaedic Surgery examination. The American Board of Orthopaedic Surgery Part II surgeon case database was queried from the years 2003 to 2013 for Current Procedural Terminology (CPT) codes related to open hip preservation surgery in patients 10 years and older. Patient demographics, fellowship training, geographic location, and complications were extracted from the database. These data were analyzed to determine the incidence by year of individual procedures and complications. During the study period, 644 cases (352 male, 292 female; mean age, 29.7 years) and 730 CPT codes were reported. The most commonly reported fellowship was pediatric orthopedics. No trend was observed in the overall incidence of these surgeries, but there was an increase in the number of cases performed in the Midwest. There were 212 reported complications, with a rate of 33% per case, or 29% per CPT code (range, 12.5%-100% per CPT code). Complications reported ranged from infection to death. The incidence of complications over time showed no discernible trend. Based on the results of this study, the yearly incidence and complications associated with open hip preservation surgery performed by surgeons undergoing board certification should continue at a predictable rate.

Current Concepts in Hip Preservation Surgery: Part II--Rehabilitation.

CONTEXT: Successful treatment of nonarthritic hip pain in young athletic individuals remains a challenge. A growing fund of clinical knowledge has paralleled technical innovations that have enabled hip preservation surgeons to address a multitude of structural variations of the proximal femur and acetabulum and concomitant intra-articular joint pathology. Often, a combination of open and arthroscopic techniques are necessary to treat more complex pathomorphologies. Peri- and postoperative recovery after such procedures can pose a substantial challenge to the patient, and a dedicated, thoughtful approach may reduce setbacks, limit morbidity, and help optimize functional outcomes. EVIDENCE ACQUISITION: PubMed and CINAHL databases were searched to identify relevant scientific and review articles through December 2014 using the search terms hip preservation, labrum, surgical dislocation, femoroacetabular impingement, postoperative rehabilitation, peri-acetabular osteotomy, and rotational osteotomy. Reference lists of included articles were reviewed to locate additional references of interest. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 4. RESULTS: Hip preservation procedures and appropriate rehabilitation have allowed individuals to return to a physically active lifestyle. CONCLUSION: Effective postoperative rehabilitation must consider modifications and precautions specific to the particular surgical techniques used. Proper postoperative rehabilitation after hip preservation surgery may help optimize functional recovery and maximize clinical success and patient satisfaction.

Current Concepts in Hip Preservation Surgery: Part I.

CONTEXT: An evolution in conceptual understanding, coupled with technical innovations, has enabled hip preservation surgeons to address complex pathomorphologies about the hip joint to reduce pain, optimize function, and potentially increase the longevity of the native hip joint. Technical aspects of hip preservation surgeries are diverse and range from isolated arthroscopic or open procedures to hybrid procedures that combine the advantages of arthroscopy with open surgical dislocation, pelvic and/or proximal femoral osteotomy, and biologic treatments for cartilage restoration. EVIDENCE ACQUISITION: PubMed and CINAHL databases were searched to identify relevant scientific and review articles from January 1920 to January 2015 using the search terms hip preservation, labrum, surgical dislocation, femoroacetabular impingement, peri-acetabular osteotomy, and rotational osteotomy. Reference lists of included articles were reviewed to locate additional references of interest. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 4. RESULTS: Thoughtful individualized surgical procedures are available to optimize the femoroacetabular joint in the presence of hip dysfunction. CONCLUSION: A comprehensive understanding of the relationship between femoral and pelvic orientation, morphology, and the development of intra-articular abnormalities is necessary to formulate a patient-specific approach to treatment with potential for a successful long-term result.

Transient synovitis, septic hip, and Legg-Calvé-Perthes disease: an approach to the correct diagnosis.

Transient synovitis, septic hip, and Legg-Calvé-Perthes disease are common conditions in children. Distinguishing between these disorders can be a diagnostic challenge. Similar presentations, in an age group difficult to examine, coupled with literature that is confusing creates difficulty. It is important to make the correct diagnosis of septic hip in a timely fashion to avoid serious and potentially crippling consequences. As there is no single test for discriminating between these conditions, knowledge of the nuances of clinical presentation, physical examination, laboratory investigations, and imaging is essential. Judicious use of clinical algorithms can complement clinical acumen.
