The main mechanisms of action thought to play a role in enhancing wound healing and preventing surgical site infection are macrodeformation and microdeformation of the wound bed, fluid removal, and stabilization of the wound environment. Due to the devastating consequences of infection in the setting of joint arthroplasty, there has been some interest in the use of NPWT following total hip arthroplasty and total knee arthroplasty. However, there is still a scarcity of data reporting on the use of NPWT within this field and most studies are limited by small sample sizes, high variability of clinical settings and end-points. There is little evidence to support the use of NPWT as an adjunctive treatment for surgical wound drainage, and for this reason surgical intervention should not be delayed when indicated. The prophylactic use of NPWT after arthroplasty in patients that are at high risk for postoperative wound drainage appears to have the strongest clinical evidence. Several clinical trialsincluding single-use NPWT devices for this purpose are currently in progress and this may soon be incorporated in clinical guidelines as a mean to prevent periprosthetic joint infections.展开更多

Methods 40 patients,45 hips with various diseases were treated by total hip joint replacement from Jan 2000 to Sep 2001.Before operation, the perpendicular length from center of femoral head to the summit of great tuberosity and the tip of less tuberosity to the line of bilateral ischial tuberosity were measured; the length from anterior superior iliac spine to medial malleolus were measured at same time.Leg length was decided and corrected according to these lines. Results Before operation, shortening of limbs were presented in 39 hips, 1 to 4 cm, average 2.4 cm.After operation, discrepancy of both legs was 0～0.8 cm.Apparent limps were not observed in all patients. Conclusion This measurement is a useful method to maintain and recover leg length in total hip joint replacement.展开更多

Ceramic-On-Ceramic (COC) interface allowed the use of larger head with reduced wear debris generation and adverse tissue reactions. This study was conducted to analyze 6-year clinical-radiological outcome with large head fourth generation DeltaMotion®ceramic-on-ceramic (COC) hip articulation, with special emphasis on postoperative ROM, ability to sit cross-legged, stability, hip noise and revision surgery. Material and Methods: 150 consecutive hips were operated for primary cementless Total Hip Replacement (THR) using DeltaMotion®at a tertiary care center in Mumbai, India, between January 2010 and January 2015. Clinico-radiological outcome was assessed using the Harris Hip Score (HHS) and radiographs at 6 weeks, 6 months, and annually thereafter. Results: 108 (74.5%) patients were males and 37 (25.5%) were females with an average age of 50.87 years. Mean follow-up was 54 months (range: 37 - 86 months). The mean ROM was 120° in flexion, 10° in extension, 30° in adduction, 45° in abduction, 25° in internal rotation and 25° in external rotation. The mean HHS showed a statistically significant improvement of 64.5% (from 54.66 ± 6.42 pre-operatively to 89.95 ± 4.32 post operatively) (p-value: 0.001). 92% of patients were able to sit in squatting position and 92% were able to sit cross-legged on the floor at last follow-up. 0.7% joints (1 hip) had squeaking. Considering no revision surgery as the end point, 6-year prosthesis survivorship was 100%. Complications (superficial infection) occurred in three hips (2%). All patients reported to be satisfied with their outcome after surgery. Conclusion: We infer that DeltaMotion large head COC bearing allows scope for using larger head size in relatively smaller Indian hips due to factory fitted ceramic lining. At 6-year follow-up, high activity level was observed with excellent clinical-radiological outcomes and component longevity in relatively young Indian population.展开更多

Methods: For the functional improvement of the patients, we relied on the scores of Devane, Harris and that of Postel Merle d’Aubeigné. The radiological analysis was based on the coxometry. Results: The study confirms the notable functional gain and consequently the improvement of the quality of life of the patients. However, the longevity of the implants remains difficult to envisage due to our limited and insufficient hindsight. Conclusion: The total hip arthroplasty transforms the life of the young patients’ carriers of the disabling coxitis on the stiffening spondylarthritis, by getting them the laziness and the mobility wished for.展开更多

Patients were followed-up from 13 to 76 months (mean: 44.5 months) and assessed using the Harris Hip Score-HHS, the Hip Disability and Osteoarthritis Outcome Score-HOOS and radiographs. <strong>Results:</strong> All stems were radiologically stable. Mean Harris Hip Score was 89.8 and the HOOS was 80.4. No statistical differences were observed among patients with different diagnoses. <strong>Conclusions:</strong> The short-term results revealed satisfactory clinical outcomes and radiological signs of implant stability in all cases. Using two functional scores was useful in detecting biases and a low to moderate agreement was found between the scores.展开更多

METHODS: We hypothesized that obese patients were treated for later stage of osteoarthritis, that more conservative implants were used, and the intraand perioperative complications increased for such patients. We evaluated all patients with body mass index(BMI) ≥ 25 who were treated in our institution from January 2011 to September 2013 for a primary total hip arthroplasty(THA) or total knee arthroplasty(TKA). Patients were split up by the levels of obesity according to the classification of the World Health Organization. Average age at the time of primary arthroplasty, preoperative Harris Hip Score(HHS), Hospital for Special Surgery score(HSS), gender, type of implanted prosthesis, and intra-and postoperative complications were evaluated.RESULTS: Six thousand and seventy-eight patients with a BMI ≥ 25 were treated with a primary THA or TKA. Age decreased significantly(P < 0.001) by increasing obesity in both the THA and TKA. HHS and HSS were at significantly lower levels at the time of treatment in the super-obese population(P < 0.001). Distribution patterns of the type of endoprostheses used changed with an increasing BMI. Peri- and postoperative complications were similar in form and quantity to those of the normal population. CONCLUSION: Higher BMI leads to endoprosthetic treatment in younger age, which is carried out at significantly lower levels of preoperative joint function.展开更多
