Aims

It is well described that patients with bone and joint infections (BJIs) commonly experience significant functional impairment and disability. Published literature is lacking on the impact of BJIs on mental health. Therefore, the aim of this study was to assess health-related quality of life (HRQoL) and the impact on mental health in patients with BJIs.

Introduction. This study reports on minimum 2 year follow up outcomes on functional and quality of life of patients after undergoing bilateral osseointegration in comparison to traditional socket prosthesis. Materials & Methods. This is a prospective pilot study of 35 patients, consisting of 30 males and 5 females, aged 22–66 (mean 36) years at surgery, with minimum two-year follow-up. Selection criteria were age over 18 years, bilateral amputees who had socket-related problems or were wheelchair-bound with short stumps and non-reconstructable limb pathology. Principle outcome measures included the Questionnaire for persons with a Trans-Femoral Amputation (Q-TFA), Short Form Health Survey 36 (SF-36), Six Minute Walk Test (6MWT), Timed Up and Go (TUG), and K-levels. Adverse events were recorded including infection, revision surgery, fractures, and implant failures. Results. Comparisons were made using differences between the mean pre-operative and mean post-operative values for each outcome measure. Significant improvements in all validated outcome measures were observed. All patient who were wheelchair bound prior to the surgery were able to mobilise post operatively. The occurrence levels of adverse events, including the infection rate and revision rate within this patient cohort, were similar to other established trans-femoral osseointegration studies. Conclusions. These preliminary results indicate that osseointegration surgery is a safe and effective alternative treatment for bilateral amputees experiencing socket-related discomfort. Compared to the suboptimal outcomes of socket prostheses, osseointegration currently provides one of the best chances for any bilateral amputee to walk again and regain the ability to perform daily activities

Traditional socket prosthesis (TSP) rehabilitation for amputees is associated with substantial dissatisfaction due to poor mobility and pain from soft tissue squeezing. Osseointegration (OI), eliminates skin compression and prosthesis fit issues, providing superior mobility and quality of life (QOL) for most amputees. The potential for OI to benefit patients with exceptionally poor mobility is understudied. To address this knowledge gap, this project investigated the mobility and QOL changes. A retrospective review was performed to identify transfemoral amputees who presented with wheelchair-bound mobility (K0) and had at least five years of post-osseointegration follow-up. Outcome measures included changes in mobility (K-level, daily prosthesis wear hours, Timed Up and Go (TUG), 6 minute walk test (6MWT)) and QOL (Questionnaire for persons with a Transfemoral Amputation (QTFA); Short Form Health Survey 36 (SF36). Adverse events recorded included debridement for infection, implant revision surgery, fractures, and implant failures. 9 patients with mean age 48.2±7.7 (range 34-59) years were included. The proportion of patients achieving K-level >2 improved from 0/9=0% to [9/9=100%], p<0.001. The 6MWT improved from 0±0 to 320.65±57 meters (p<0.001). The TUG improved from incapable to 10.68±2.7 seconds (p<0.001). Statistically significant QOL metrics included QTFA global score (33.33±31 vs 68.52±21, p=0.039), SF36 physical component score (30.03±6.3 vs 42.34±12, p=0.023) and the SF36 mental component score (47.89±8.8 vs 51.95±10.4, p=0.332). Six patients required operative intervention to address complications. Five developed infections: three had debridement, and 2 required implant removal and reimplantation. Osseointegration does confer significant sustained mobility and quality of life improvement for wheelchair bound transfemoral amputees. All 9 K0 patients had statistically improved mobility and QOL after osseointegrated reconstruction. This supports osseointegration as an effective rapid and long-term rehabilitation alternative for patients who have the neurologic and muscular capacity to walk but are unable due to issues related to their TSP

Introduction. Functional outcomes of mechanically aligned (MA) total knee arthroplasty have plateaued. The aim of this study is to find an alternative technique for implant positioning that improves functional outcomes of TKA. Methods. We prospectively randomized 100 consecutive patients undergoing TKA into two groups: in the group A an intramedullary femoral guide and an extramedullary tibial guide were used with aim to obtain a neutral traditional mechanical alignment; in the group B an extramedullary femoral guide set on distal femoral condyles and an extramedullary tibial guide neutrally aligned were used to obtain an adaptation of the conventional MA technique. Patients were followed-up clinically with the Short Form Health Survey (SF-12), Oxford Knee Score (OKS) and Visual Analogue Score (VAS) questionnaires pre-operatively and then at 1 year post-operatively. Mechanical alignment was calculated on standing weight bearing Xray pre- and post-operatively. T-test was used to compare the results between groups. Results. Both groups showed an improvement of clinical scores. At 1 year of follow-up OKS and SF-12 were significantly higher in group B: 47,6 ±0.75 and 46.5 ±0.76 respectively; VAS was similar in both groups. Values of mechanical alignment changed from 6.45 ±8.45 to 0.25 ±0.91 for group A and from 6.8 ±7.94 to 2.5 ±4.7 for group B. Conclusion. This study shows that adjusted mechanical alignment (AMA) with a small under-correction of frontal deformity lead to improved functional scores following total knee replacement compared to conventional technique of neutral alignment. These results are satisfactory at short follow-up but long-term studies are needed to evaluate the difference in the rate of wear of the prosthetic components

BACKGROUND:. Few studies have evaluated at a medium-term follow-up the use of semiconstrained reverse shoulder arthroplasty (RSA) for primary glenohumeral osteoarthritis, massive rotator cuff tear, or cuff tear arthropathy excluding any other shoulder disease. Moreover, data on patients' quality of life after this surgery are lacking. METHODS:. In this prospective cohort study, 80 patients were evaluated after an RSA for either primary osteoarthritis, massive rotator cuff tear, or cuff tear arthropathy with the Constant-Murley score (CMS), ROM, and Short Form Health Survey (SF-36). A radiologic assessment was performed pre- and postoperatively. RESULTS:. At a mean 5-year follow-up, the cumulative survival rate was 97.3% and significant improvements in the CMS and ROM were observed when compared with the baseline values. The CMS was 93.2% of the sex- and age-matched normal values. The postoperative SF-36 scores showed no significant differences compared with normative data. Younger patients and subjects with worse preoperative conditions achieved the greatest benefit after RSA. A 70% scapular notching rate was noted and the length of follow-up was found to be associated with the severity of scapular notching. CONCLUSIONS:. This study introduces new predictors for surgical outcomes, and it shows that patients who had undergone RSA a mean of 5 years earlier exhibit similar functionality and health-related quality of life with respect to healthy controls

Aim. Very limited information is available regarding health-related quality of life (HRQOL) and patient reported hip function following treatment for chronic periprosthetic hip joint infection (PJI). Several reviews have not found any clear differences in clinical outcome parameters comparing the most commonly applied treatment strategies for chronic hip PJI. Studies describing patients HRQOL of one-stage and two-stage revision could provide important information regarding patient counselling. The purpose of this study was to investigate HRQOL and patient reported hip function after one-stage revision and two-stage revision in chronic hip PJI. Method. The one-stage group was identified in a prospective clinical study on one-stage revision in chronic hip PJI. Fifty-one patients were followed for two years on an outpatient basis and completed three questionnaires; EuroQol-5D (EQ-5D), Short Form Health Survey 36 (SF-36) and Oxford Hip Score (OHS) at 3, 6, 12 and 24 months follow-up. The two-stage group was identified retrospectively in the National Patient Register and 45 patients completed EQ-5D and OHS. The observed results were compared to normative population data for SF-36 and EQ-5D. Results. In the one-stage group the improvement in HRQOL appeared in the first 6 months after surgery, reached a plateau, and decreased slightly again. The largest improvements at 2 years were OHS with an effect size (ES): 1.3 and SF-36's physical role limitation and bodily pain with ES: 1.1. The one-stage group reached the matched population norm on all parameters at 12 months, but two scores declined from 12 to 24 months: physical functioning (66 to 50 (out of 100, population norm 71) and physical role limitation (58 to 40, population norm 63). Neither the one-stage nor the two-stage group reached the EQ-5D population norm. When comparing the two groups, the mean scores (CI 95%) for one-stage revision were significantly higher compared to the two-stage revision group on EQ-5D. VAS. 12.9 (2.4;23.3 p=0.02) and OHS 5.9 (0.5;11.2 p=0.03), but not on EQ-5D. index. 0.065 (−0.04;0.17 p= 0.22). Conclusions. Two years after receiving one-stage revision the patients experienced a significant increase in HRQOL and reported hip function, and matched the population norm on most parameters. The decrease in physical scores at 24 months could be attributed to co-morbidities. Neither group reached the EQ-5D population norm. Patients receiving one-stage revision obtained higher HRQOL and hip function compared to two-stage revision. However, a direct comparison of the two groups cannot be performed due to difference in study design

Delayed union and non-union are complications of fracture healing associated with pain and with functional and psychosocial disability. This study compares the effect on self-reported health outcomes of delayed union or non-union of femoral and tibial shaft fractures treated at two major metropolitan trauma centres in Victoria. Patients admitted to the Royal Melbourne Hospital and The Alfred with extra- articular femoral and tibial shaft fractures during 2003-2004 and 2005-2006, and followed up by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) were included. Hospital medical records were reviewed to identify the outcome of each fracture. Fracture healing was assessed by the need for unplanned revision surgery for delayed union or nonunion, and clinical and radiological evidence of union. Prospectively-gathered VOTOR health outcome measurements included the Short Form 12-Item Health Survey (SF-12), and return to work and pain status at 6 and 12 months post injury. Of the 520 patients, 260 femoral and 282 tibial shaft fractures were included. In total, 285 fractures progressed to union, 138 fractures developed delayed union or non-union and 119 fractures had an unknown outcome. Factors that were significantly different between the union and delayed union or non-union groups included: fund source, mechanism of injury, other injuries, wound and Gustilo type, and fixation method. On linear regression modelling, an inverse relationship was demonstrated between delayed union or nonunion and the Physical and Mental Component Summary scores of the SF-12. This was statistically significant at both 6 and 12 months post injury unadjusted and adjusted for age, gender and other injuries. On logistic regression modelling, patients with delayed union or non-union showed unadjusted and adjusted risk ratios of 0.85 and 0.82, respectively at 6 months, and 0.82 and 0.76, respectively at 12 months to return to work. Similarly, patients with delayed union or nonunion had unadjusted and adjusted risk ratios of 1.09 and 1.11, respectively at 6 months, and 1.33 and 1.37, respectively at 12 months to have pain. Both were statistically significant at 12 months post injury unadjusted and adjusted for age, gender and other injuries. Patients with delayed union or non-union of femoral and tibial shaft fractures have poorer physical and mental health at 6 and 12 months post injury. In addition, they are less likely to have returned to work and more likely to still have pain at 12 months post injury

Introduction:. Total hip arthroplasty (THA) is extremely effective in treating debilitating arthritic conditions of the hip. With the many modular prosthetic designs available, surgeons can now precisely construct mechanical parameters such as femoral offset (FO). Although several studies have investigated relationships between offset choice and hip abductor strength, hip range of motion, and prosthetic wear rate, there is scarce data on the effect of FO on pain and functional outcomes following THA. The objective of this study was to assess the effect of restoring FO (within varying degrees compared to the contralateral non-diseased hip [CL]) on physical function, mental well-being, pain, and stiffness outcomes as measured by the Short Form 12 Health Survey (SF-12) and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) at post-operative follow-up. Methods:. We prospectively collected data on 249 patients that underwent unilateral THA with no or minimal disease of the contralateral hip. Baseline data collection included: age, gender, diagnosis, femoral head size, type of stem, and pre-operative SF-12 and WOMAC scores. Post-operative SF-12 and WOMAC scores were recorded during annual follow-up visits. Post-operative FO was retrospectively measured on standard anteroposterior (AP) pelvis radiographs and compared to FO of CL. FO was measured as the perpendicular distance from the femoral head center of rotation to the anatomic axis of the femur with appropriate adjustments made for image magnification. Patients were categorized into one of three groups: decreased femoral offset (dFO, less than −5 mm compared to CL), normal femoral offset (nFO, between −5 and +5 mm of CL), and increased femoral offset (iFO, greater than +5 mm compared to CL). Results:. In all, 31 patients were categorized into dFO, 163 categorized into nFO, and 55 categorized into iFO. At baseline, the groups differed in categorical diagnoses (p = 0.01). Further analysis revealed a higher percentage of posttraumatic arthritis in dFO as compared to nFO and iFO (12.9%, 1.2%, and 1.8%, respectively). Moreover, a higher percentage of hip dysplasia was present in iFO as compared to nFO and dFO (14.5%, 3.6%, and 6.5%, respectively). Pre-operatively, dFO had lower WOMAC Pain scores than nFO and iFO (29.68, 43.39, and 43.63, respectively; p < 0.005). (Please see Table 1 for comparison of baseline characteristics between groups.) All other pre-operative demographic and survey characteristics were similar. At most recent post-operative follow-up, dFO had lower WOMAC Physical Function scores than nFO and iFO (72.03, 83.23, and 79.51, respectively; p < 0.02) (see Table 2). Discussion:. Reduction of patients' native FOs by greater than 5 mm during THA can lead to inferior levels of physical function. Furthermore, increasing FO by greater than 5 mm did not lead to increased levels of pain nor decreased levels of function

Aims

Patients undergoing limb reconstruction surgery often face a challenging and lengthy process to complete their treatment journey. The majority of existing outcome measures do not adequately capture the patient-reported outcomes relevant to this patient group in a single measure. Following a previous systematic review, the Stanmore Limb Reconstruction Score (SLRS) was designed with the intent to address this need for an effective instrument to measure patient-reported outcomes in limb reconstruction patients. We aim to assess the face validity of this score in a pilot study.
