AbstractThe survivorship of contemporary total hip arthroplasty has improved substantially as a result of the success of highly cross-linked polyethylene. Nevertheless, there is limited information on its performance in extremely young patients. The purpose of this study is to evaluate the (1) clinical and radiographic outcomes, (2) polyethylene wear rates, and (3) mid-term survivorship of total hip arthroplasty in patients 21 years or younger using highly cross-linked polyethylene. After Institutional Review Board approval, the authors identified 45 patients aged 21 years or younger (56 hips) who underwent primary total hip arthroplasty with highly cross-linked polyethylene at their institution by the senior author between 2000 and 2009. Patients were followed for a minimum of 2 years, or until revision. At a mean follow-up of 57 months, modified Harris Hip Scores, Western Ontario McMaster Universities Arthritis Index scores, Short Form-12 physical function scores, and University of California, Los Angeles activity scores improved significantly in all patients. There was no radiographic evidence of osteolysis in any patient. The mean linear polyethylene wear rate was 0.02 mm per year. Survivorship was 98% with one revision for acetabular loosening at 71 months. Total hip arthroplasty in patients 21 years or younger with highly cross-linked polyethylene had excellent clinical and radiographic outcomes at mid-term follow-up. Longer-term data are needed in this patient population to confirm continued survivorship in the extremely young. The level of evidence used for this study was level III.

Abstract BackgroundThe increase rate seen in Total Hip Arthroplasty (THA) for younger patients has implications for future rehabilitation demands for primary and revision THA surgery. This study aims to determine the impact of a 6-week post-operative rehabilitation program designed for THA patients ≤ 60 years on physical activity (PA) and function compared to age- and a sex-matched control group received usual postoperative care at 12-week post-THA. MethodsIn this quasi-experimental study, a cohort of THA candidates was recruited during their 6-week postoperative visit to their surgeons. The out-patient rehabilitation program consisted of 12 structured exercise classes (2 hrs/class) over 6 weeks. Physical activity was assessed using Sense Wear Pro ArmbandTM [SWA]. Participants completed the Hip Osteoarthritis Outcome Score (HOOS), and THA satisfaction questionnaire before and immediately after the intervention. ResultsThe intervention group took significantly more steps/day at the follow-up compared to baseline. The intervention group had a higher mean change in the number of weekly PA bouts than the control group. Within the intervention groups, all HOOS subscales were significantly higher at the follow-up compared to baseline. ConclusionThe augmented rehabilitation program may have immediate effects on pain relief and symptom reduction for patients (≤60 years) following THA.

ABSTRACT Concerns remain about total hip arthroplasty (THA) performed in very young patients, especially those with complex medical history such as allogeneic bone marrow transplantation (ABMT). This study retrospectively reviews the perioperative courses and functional outcomes of ABMT patients <21 years old undergoing primary uncemented THA. Nine THAs were performed in five ABMT patients at an average age of 19.7 years. The interval between ABMT and THA was 73.0 months with clinical follow-up of 25.8 months. Harris Hip Scores (HHS) increased dramatically from preoperatively 44.5 (31.1-53.4) to postoperatively 85.2 (72.0-96.0) and all patients subjectively reported a good (4 hips) to excellent (5 hips) overall outcome. There was one reoperation for periprosthetic fracture fixation but there were no infections or revisions performed. Despite the history of severe hematopoietic conditions requiring ABMT, these very young patients do appear to have improved pain and function following primary THA with short-term follow-up. These results are comparable to prior studies of adult ABMT patients undergoing THA and are encouraging given the complexity of the decision to perform hip arthroplasty in the medically complicated very young patient.

Background: The management of degenerative hip diseases in young patients remains a challenge. Despite the improvement of hip-preserving procedures, total hip arthroplasty (THA) may be required in some instances. In addition, young patients undergoing THA have high expectations concerning their postoperative level of activity. Purpose: (1) to define the sports activity level and the return to sports after THA, (2) to describe the modification or initiation of new sports disciplines, and (3) to report the clinically meaningful outcomes after THA in patients younger than 40 years. Methods: A total of 36 patients (40 hips) were prospectively analyzed at a midterm follow-up of 3.9 years. The modified Harris Hip Score (mHHS); the Visual Analog Scale (VAS) for pain; the University of California, Los Angeles (UCLA) activity scale; and sports and recreational activity levels were assessed via questionnaire. The minimal clinically important difference (MCID) was determined by calculating half of the standard deviation, and the substantial clinical benefit (SCB) as well as patient acceptable symptomatic state (PASS), were calculated by the anchor method for the mHHS. Results: At the final follow-up, there was a significant improvement in mHHS (34.1 to 92.6; p < 0.0001), UCLA (3.2 to 7.6; p < 0.0001), and VAS for pain (8 to 1; p < 0.0001). More patients were active in sports at follow-up than before surgery (44% to 92%, p < 0.0001). In addition, the duration and frequency of sports activities showed a significant increase (p < 0.0001). The MCID, SCB and PASS for mHHS were 89% and 58%, respectively. No revision surgery had to be performed. Conclusion: This study showed that a large proportion of patients under 40 years of age who underwent THA increased their physical activity. Eighty-six percent of the patients were highly active, with a UCLA score ≥ 7. Furthermore, the reported MCID, SCB, and PASS for mHHS were achieved by more than 80% of patients.

Abstract Background: The increase rate seen in total hip arthroplasty (THA) for younger patients (< 60) has implications for future rehabilitation demands for primary and revision THA surgery. The primary objective is to examine the feasibility of a study comparing a 6-week post-operative rehabilitation program to usual care in patients ≤ 60 years undergoing elective unilateral THA. The secondary objectives are: 1) to explore the effect of a 6-week post-operative rehabilitation program designed for THA patients ≤ 60 years on physical activity (PA), function and participants’ satisfaction compared to age- and sex-matched control group received usual postoperative care at 12-week post-THA. 2) to examine the correlation between physical activity and self-reported pain and function.Methods: In this study, a cohort of THA candidates were recruited during their 6-week postoperative visit to their surgeons at a central intake clinic. The out-patient rehabilitation program, which was designed to improve function and increase activity, consisted of 12 structured exercise classes (2 hrs/class) on land and water over 6 weeks. Physical activity was assessed using Sense Wear Pro ArmbandTM [SWA]. Participants completed the Hip Osteoarthritis Outcome Score (HOOS), and THA satisfaction questionnaire before and immediately after the intervention.Results: Of the 24 participants recruited, 14 participants received the augmented rehabilitation, and 10 participants were in the control group. All the study participants in the control and intervention groups completed the baseline and follow-up assessments without adverse events. Thirteen out of the fourteen intervention group participants completed at least 80% of the intervention sessions. The intervention group took significantly more steps/day (mean difference = 2,440 steps/day, 95% CI= 1678, 4712) (p<0.05), at the follow-up compared to baseline. The intervention group had a higher mean change of number of weekly PA bouts than the control group. Within the intervention group, all HOOS subscales were significantly higher at the follow-up compared to baseline. However, the ADL subscale was the only significant difference seen with the control group.Conclusion: The study intervention and assessments were feasible and safe in patients ≤ 60 years undergoing elective unilateral THA.

AbstractThe emergence of highly cross-linked polyethylene (HCLPE) has drastically improved survivorship of implants used in total hip arthroplasty (THA), as demonstrated by midterm outcomes. However, there is limited data evaluating long-term outcomes and wear rates of these liners. Therefore, the aim of this study is to evaluate the longest-to-date follow-up of a specific second-generation HCLPE liner, the progression of wear rate, and its relation to acetabular cup positioning. A retrospective study was conducted on patients who underwent THA between January 2001 and December 2005 using a specific second-generation HCLPE liner. Annual liner wear rate (mm/year) was calculated in this group as well as acetabular positioning through abduction angle (degrees). Failures and reason for failures such as periprosthetic fracture, dislocation, and osteolysis were noted when applicable. Forty hips of 35 patients were included in this study with a clinical and radiographic follow-up of 13.4 ± 2.2 years (range: 10.0–16.7 years). Linear and volumetric wear rates were calculated to be 0.037 ± 0.020 mm/year and 22.94 ± 12.07 mm3/year, respectively. No radiographic femoral or acetabular osteolysis was observed in any of the cases. One patient required revision due to complications unrelated to the liner. No significant relationship could be established for acetabular component abduction angle and linear wear rate (p = 0.690, Spearman's rho = 0.03). Our study demonstrates comparable liner wear rates to that of other second-generation HCLPE liners in long-term follow-up. The XLPE liner continues to exhibit minimal progression of linear wear when compared with previous midterm studies and maintains a low rate of postoperative complications requiring revision THA surgery. Further studies are warranted to assess long-term wear and survivorship between this specific liner and comparable HCLPE models.

Introduction Total hip arthroplasty (THA) in the young is challenging. The purpose of this study was to retrospectively determine the clinical, radiographic, and polyethylene wear rate of relatively young patients. Methods We evaluated the outcome of consecutive patients receiving primary THA who were under 40 years of age with a minimum 10-year follow-up. Indications for THA in these patients were osteoarthritis due to developmental dysplasia of the hip joint (9 hips), osteonecrosis of the femoral head (7 hips), juvenile idiopathic arthritis (2 hips), and osteoarthritis due to Perthes disease (1 hip). All THA were performed with a cross-linked ultra-high-molecular-weight polyethylene (XLPE) liner against zirconium heads with cementless implants. Results The average Japanese Orthopaedic Association hip score significantly improved from 42 to 93 points at the latest follow-up. The mean steady wear was 0.015 mm/year (maximum 0.033 mm/year), and the mean creep wear was 0.111 mm (maximum 0.4 mm). Osteolysis was observed around 1 acetabular component and 2 stems. 1 femoral component had subsidence over 5 mm. All of the femoral components achieved fixation with an optimal interface with spot welds at the latest follow-up. Stress shielding was observed in all hips. Conclusions THA using an XLPE liner against zirconium heads appeared to have improved THA longevity. However, the imaging findings in some cases were suggestive of wear debris. A rigorous continual follow-up is required for relatively young patients undergoing THA.
