Abstract Background: The supercapsularpercutaneously-assisted total hip (SuperPATH) approach is a micro-invasive approach that was developed to minimize surgical disruption of soft-tissue during routine total hip arthroplasty (THA). This study aimed to assess early outcomes and learning curves of the SuperPATHapproachin one Chinese hospital’s experience.Methods: Early outcomes of the first consecutive 78SuperPATH cases (80 hips) performed by same surgeon were evaluated. The patients were divided into 4 groups according to the surgical order. The incision, intraoperative blood loss, hospital stay, Harris hip score and complications occurrence in each group were evaluated. Learning curves were assessed using operative time and intraoperative blood loss as surrogates.Results:The operation time and intraoperative blood loss of group A and B was more than that of group C and D, and the difference was statistically significant (P<0.05), however there was no statistically significant difference between the two groups (group A vs. group B, P=0.426; group A vs. group B, P=0.426).There was no statistically significant difference in terms of incision length and hospital stay and Harris hip score at the last follow-up was increased with statistically significant difference when compared with that of preoperative among the 4 groups. One case of periprosthetic fracture occurred in group A. No other complication, such as joint dislocation, sciatic nerve injury, prosthesis loosening, periprosthetic infection and deep vein thromboembolism, occurred in 4 groups.Conclusion:In summary, for surgeons who familiar with the standard posterolateral approach, they could achieve more familiar with SuperPATH after 40 case of surgery.

Abstract Background Whether using tissue adhesive alone after subcutaneous suture can close the skin incision with safety as well as cosmetic appearance after total hip arthroplasty was not clear. Methods A prospective study was conducted. The same surgical methods were consistent throughout the entire study. After implanting prosthesis, the joint capsule was reconstructed. Fascial and subcutaneous layer were respectively closed by continuous running barbed suture. Patients were randomized allocated to group A with octyl-2-cyanoacrylate tissue adhesive alone, to group B with tissue adhesive after continuous subcuticular suture, or to group C with skin staples. Time of closure, drainage, pain, wound complications, and cosmesis were compared. All data were analyzed statistically. Results There was no significant difference in drainage, Visual Analog Scale score or early wound complications between the three groups. However, there was significant difference in time of closure (P = 0.013). In pairwise comparison, time of closure in groups A and B was significantly longer than those in group C (P = 0.001 and P = 0.023, respectively); time of closure in group A was significantly shorter than those in group B (P = 0.003). Patient and Observer Scar Assessment Scale total scores were not significantly different at 6 weeks and 3 months postoperatively (P = 0.078 and P = 0.284, respectively). Conclusion Tissue adhesive without subcuticular suture was similar with a combination of subcuticular suture and tissue adhesive as well skin staples in terms of safety and cosmetic appearance after total hip arthroplasty.

Abstract Background: High hip center technique is still controversial about the survivorship of prothesis and postoperative complications. We aimed to show the utility of high hip center technique used in patients with Crowe II-III developmental dysplasia of the hip at the midterm follow-up and evaluated the clinical and radiographic results between different heights of hip center.Methods: We retrospectively evaluated 69 patients (85 hips) with Crowe II-III dysplasia who underwent a high hip center cementless total hip arthroplasty at a mean follow up of 8.9 years (range, 6.0-14.1years). The patients were divided into two groups according to the height of hip center, respectively group A (≥22mm and <28mm) and group B (≥28mm). Radiographic, functional and survivorship outcomes were evaluated.Results: There were no statistically significant differences between two groups in horizontal distance, offset, abductor lever arm, leg length discrepancy and cup inclination. At the final follow up, the mean WOMAC and Harris hip score were significantly improved in both groups. Of the 85 hips, 7 hips (8.2%) showed a positive Trendelenburg sign. Besides, 6 patients (8.7%) presented with a limp. No significant differences were shown regarding the Harris hip score, WOMAC score, Trendelenburg sign and limp between two groups. The Kaplan-Meier implants survivorship rates at the final follow-up for all-causes revisions in group A and group B were similar (96.7% [95% confidence interval, 90.5%-100%] and 96.2% [95% confidence interval, 89.0%-100%], respectively).Conclusions: The high hip center technique is a valuable alternative to achieve excellent midterm results for Crowe II-III developmental dysplasia of the hip.

Primary Total Hip Arthroplasty

Introduction: Total hip arthroplasty (THA) is a well-established procedure for advanced arthritis of the hip joint. It significantly improves the quality of life by relieving pain and improving functional disability. The objective of this study was to evaluate the clinical and functional outcome of primary total hip arthroplasty using the Harris Hip Score. Method: Prospective study was conducted in Civil Service Hospital. Out of 145 THA performed from Jan 2014 to Dec 2018, the first 100 cases that fulfilled the inclusion criteria were analyzed.  Patient demographic and site, operative indication, and pre-operative Harris Hip Score was documented. Operative time, total intraoperative blood loss, and complications were noted. Patients were followed in 3 weeks, 6 weeks, 3 months, 6 months, and yearly. In each visit, clinical evaluation using Harris Hip Score and radiological evaluation was done and documented. The duration of follow up ranged from 12 months to 4.5 years. Results: Age varied from 21 to 75 years, 59% were male and 41% female, right side involvement was seen in 55% and left side in 45%. The major indication for surgery was avascular necrosis 46% and primary osteoarthritis in 24%. The average operative time was 65 minutes and the average intraoperative blood loss was 655 ml. Pre-operative Harris Hip Score ranged from 25 to 59 with a mean of 45.5. The mean Harris hip score in last follow up increased to 90.5 with a minimum of 76 and a maximum of 97. Our study found that 85% had excellent, 9% had good and 6% had fair results. Complications include 2% dislocation, 1% infection, 1% greater trochanter avulsion and 1% screw irritation. Conclusion: Primary THA is a safe and effective procedure. It improves pain and function hence improving the activity of daily living and has fewer complications.

Abstract Background The direct anterior approach for total hip arthroplasty (THA) has specific advantages, but injury to the tensor fasciae lata muscle (TFLM) remains a concern. This injury in part negates some of the advantages of the intermuscular approach, because injury of the muscle fibers of the TFLM can lead to less satisfactory clinical results. Thus, in this study, we propose an intraoperative method to protect the TFLM and demonstrate its feasibility. Methods Fifty-six patients undergoing THA by the direct anterior approach were divided randomly into two groups. In group A, the TFLM was protected by an autogenous tissue “pad” created from the anterior capsule of the joint which protect the TFLM from direct contact with the retractors. In group B, the operation was carried out with no protection of the TFLM except the attempt by the surgeons to consciously avoid injury of the TFLM. We evaluated magnitude of changes in the muscle cross-sectional area (MSCA) and fatty atrophy (FA) by magnetic resonance imaging. The differences in blood hemoglobin and serum levels of myoglobin, lactate dehydrogenase (LDH), and creatine phosphokinase (CPK) were compared at different time, postoperatively. The Harris hip score, postoperative drainage volume and visual analogue scores (VAS) were compared between the two groups. Results LDH, CPK and myoglobin in group B were significantly higher than group A at 8, 24, and 48 h after the surgery. (p < 0.05) Compared to the group A, the decrease of hemoglobin in group B displayed significantly at 24 and 48 h after surgery. (P < 0.05) The significantly increased MSCA and FA of TFLM were demonstrated in group B. The PDV and VAS in group B were significantly higher than group A. (P < 0.05) The Harris score in group A was significantly higher than group B (P < 0.05) one month after surgery, but there was no significant difference six months later. Conclusions Using the anterior capsule of the hip joint as an autogenous, protective capsular tissue pad to limit the trauma to the TFLM during a direct anterior approach to THA is an effective method to protect the TFLM and improve the clinical effect.

Thrust Plate Prosthesis

Introduction: The thrust plate prosthesis (TPP) was introduced to preserve bone in patients undergoing total hip arthroplasty. We assessed the long-term results of hip arthroplasty in patients who received the TPP compared to a traditional intramedullary stem (Bi-Metric). Methods: In this prospective observational cohort study, we evaluated bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA), radiological imaging and clinical outcome using Harris Hip Score (HHS). Twenty patients received the TPP (group A) and 18 patients received the Bi-Metric stem (group B). Baseline was the 1st postoperative day, and subsequent follow-up was performed at 6 months, 1, 2, 8, 12 and 15 years after surgery. A four regions of interest (ROI) protocol was developed to assess BMD. Results: In ROI1, bone resorption was significantly higher for group A at 6 months with a mean difference of 10% (95% confidence interval [CI], 4–16; p = 0.003) and 8% (95% CI, 1–15; p = 0.03) at 8 years. Regarding ROI4, group A had a lesser decrease in general compared to group B. The radiological findings did not reveal any subsidence or detectable implant migration. HHS improved from 53 (23–69) to 93 (55–100) in group A and from 51 (24–72) to 94 (78–100) in group B. Conclusion: The TPP was not found to be inferior to the Bi-Metric stem regarding bone preservation. The decrease in BMD in ROI4 was greater in group B. Clinical and radiological results also revealed that the TPP was not inferior to the Bi-Metric stem.

Abstract BackgroundLess invasive hip-preserving surgery (LIHP) is an effective treatment in delaying total hip arthroplasty (THA) for young patients with osteonecrosis of the femoral head (ONFH). But the success rate of it was not as effective as expected and were significantly reduced with the advancement of the diseases stages. Therefore, it is essential to analysis the impact of LIHP on subsequent THA.MethodsThe search language was restricted to Chinese and English, and the references of included studies were also searched. Chinese databases including CNKI, Wan-Fang databases and VIP, and English databases including PubMed, Embase and Cochrane library were searched by the computer from the inception of each database to 23rd May 2021. The outcome indicators were extracted from the included literature and analyzed by Cochrane Collaboration Review Manager software (RevMan version 5.4). The quality of the studies was scored using the Newcastle-Ottawa scale (NOS).ResultsA total of nine articles met the inclusion and were included in this meta-analysis, two of them were published in Chinese and the remaining studies were published in English. Results showed that the LIHP group has longer operative time (SMD=17.31, 95%CI=6.29 to 28.32, p=0.002), more intraoperative blood loss (SMD=79.90, 95%CI=13.92 to 145.87, p=0.02) and higher rate of varus or valgus femoral stem (OR=4.17, 95%CI=1.18 to 14.71, p=0.03) compared to primary THA group. The risk of intraoperative fracture was higher in the prior LIHP THA group compared with primary THA group but the difference was not statistically significant (OR=5.88, 95%CI=0.93 to 37.05, p=0.06). While there was no significant difference in cup anteversion angle (SMD=-0.10, 95%CI=-0.61 to 0.41, p=0.70), cup inclination angle (SMD=0.58, 95%CI=-0.05 to 1.22, p=0.07), postoperative Harris Hip Score (HHS) (SMD=-0.01, 95%CI=-0.43 to 0.46, p=0.96) and survivorship (OR=1.38, 95%CI=0.34 to 5.55, p=0.65) between THA groups with and without prior LIHP.ConclusionAlthough the prior LIHP increased the difficulty of the conversion to THA with longer operative time, more intraoperative blood loss, and higher rate of intraoperative fracture, it does not detrimentally affect the clinical results of subsequent THA in the mid-term following-up.

Purpose: Total hip arthroplasty (THA) for high-riding hips is a complex procedure and the requirement for subtrochanteric osteotomy (STO) is an important decision that needs to be taken preoperatively. STO renders this complex surgery even more complicated and there are no guidelines to determine the STO requirement. In this study, the outcomes of THA for patients with high-riding hips were evaluated and a practical classification system is proposed to predict any osteotomy requirement. Methods: A retrospective evaluation was made of 79 hips of 76 patients who underwent THA for high-riding hip dysplasia. The amount of shortening in patients with STO and in patients without STO was compared. All patients were evaluated in respect of Harris hip score, operating time, erythrocyte suspension need, and actual limb length discrepancy. Preoperative radiographs were classified into four types according to the ratio of the distance between the lesser trochanter and the ischial tuberosity with pelvic height (LT-IT/P) to grade the degree of dislocation. Results: The mean follow-up was 30 ± 6.54 months. STO was applied to 47 (60%) hips and not to 32 (40%). There was no statistically significant difference between the groups in respect of the functional scores. STO prolonged the operating time and increased the need for blood transfusion ( p = 0.026, p < 0.001, respectively). When the LT-IT/P index was <0.19 (type 1), no additional surgical approach was required for reduction, at 0.19–0.29 (type 2), the head can be safely reduced with additional reduction methods, and when >0.3 (type 3), a shortening osteotomy will most likely be required. The rate of complications is increased if LT-IT/P is >0.4 (type 4). Conclusion: STO adjunct to THA increases the rate of complications. This practical classification system may guide the surgeon in the decision of whether an STO should be added to the procedure or not. Level of evidence: Level III, clinical trial

AbstractTranexamic acid (TXA) reduces surgical blood loss and alleviates inflammatory response in total hip arthroplasty. However, studies have not identified an optimal regimen. The objective of this study was to identify the most effective regimen of multiple-dose oral TXA in achieving maximum reduction of blood loss and inflammatory response based on pharmacokinetic recommendations. We prospectively studied four multiple-dose regimens (60 patients each) with control group (group A: matching placebo). The four multiple-dose regimens included: 2-g oral TXA 2 hours pre-operatively followed by 1-g oral TXA 3 hours post-operatively (group B), 2-g oral TXA followed by 1-g oral TXA 3 and 7 hours post-operatively (group C), 2-g oral TXA followed by 1-g oral TXA 3, 7 and 11 hours post-operatively (group D) and 2-g oral TXA followed by 1-g oral TXA 3, 7, 11 and 15 hours post-operatively (group E). The primary endpoint was estimated blood loss on post-operative day (POD) 3. Secondary endpoints were thromboelastographic parameters, inflammatory components, function recovery and adverse events. Groups D and E had significantly less blood loss on POD 3, with no significant difference between the two groups. Group E had the most prolonged haemostatic effect, and all thromboelastographic parameters remained within normal ranges. Group E had the lowest levels of inflammatory cytokines and the greatest range of motion. No thromboembolic complications were observed. The post-operative four-dose regimen brings about maximum efficacy in reducing blood loss, alleviating inflammatory response and improving analgaesia and immediate recovery.
