Our objective was to conduct a systematic review and meta-analysis, comparing differences in clinical outcomes between either autologous or synthetic bone grafts in the operative management of tibial plateau fractures: a traumatic pattern of injury, associated with poor long-term functional prognosis. A structured search of MEDLINE, EMBASE, The Bone & Joint and CENTRAL databases from inception until 07/28/2021 was performed. Randomised, controlled, clinical trials that compared autologous and synthetic bone grafts in tibial plateau fractures were included. Preclinical studies, clinical studies in paediatric patients, pathological fractures, fracture non-union or chondral defects were excluded. Outcome data was assessed using the Risk of Bias 2 (ROB2) framework and synthesised in random-effect meta-analysis. Preferred Reported Items for Systematic Review and Meta-Analysis guidance was followed throughout. Six comparable studies involving 352 patients were identified from 3,078 records. Following ROB2 assessment, five studies (337 patients) were eligible for meta-analysis. Within these studies, more complex tibia plateau fracture patterns (Schatzker IV-VI) were predominant. Primary outcomes showed non-significant reductions in articular depression at immediate postoperative (mean difference −0.45mm, p=0.25, 95% confidence interval (95%CI): −1.21-0.31mm, I. 2. =0%) and long-term (>6 months, standard mean difference −0.56, p=0.09, 95%CI: −1.20-0.08, I. 2. =73%) follow-up in synthetic bone grafts. Secondary outcomes included mechanical alignment, limb functionality, defect site pain, occurrence of surgical site infections, secondary surgery, perioperative blood loss, and duration of surgery. Blood loss was lower (90.08ml, p<0.001, 95%CI: 41.49-138.67ml, I. 2. =0%) and surgery was shorter (16.17minutes, p=0.04, 95%CI: 0.39-31.94minutes, I. 2. =63%) in synthetic treatment groups. All other secondary measures were statistically comparable. Our findings supersede previous literature, demonstrating that synthetic bone grafts are non-inferior to autologous bone grafts, despite their perceived disadvantages (e.g. being biologically inert). In conclusion, surgeons should consider synthetic bone grafts when optimising peri-operative patient morbidity, particularly in complex tibial plateau fractures, where this work is most applicable

Debate surrounds the optimum operative treatment of periprosthetic distal femoral fractures (PDFFs) at the level of well fixed femoral components; lateral locking plate fixation (LLP-ORIF) or distal femoral replacement (DFR). To determine which attributed the least peri-operative morbidity and mortality we performed a retrospective cohort study of 60 consecutive unilateral PDFFs of Su types II (40/60) and III (20/60) in patients ≥60 years; 33 underwent LLP-ORIF and 27 underwent DFR. The primary outcome measure was reoperation. Secondary outcomes included perioperative complications and functional mobility status. Kaplan Meier survival analysis was performed. Cox multivariable regression analysis identified risk factors for reoperation after LLP-ORIF. Mean length of follow-up was 3.8 years (range 1.0–10.4). One-year mortality was 13% (8/60). Reoperation rate was significantly higher following LLP-ORIF: 7/33 vs 0/27, p=0.008. For the endpoint reoperation, five-year survival was better following DFR: 100% compared to 70.8% (51.8 to 89.8 95%CI) (p=0.006). For the endpoint mechanical failure (including radiographic loosening) there was no difference at 5 years: ORIF 74.5% (56.3 to 92.7); DFR 78.2% (52.3 to 100), p=0.182). Reoperation following LLP-ORIF was independently associated with medial comminution: HR 10.7 (1.45 to 79.5, p=0.020). Anatomic reduction was protective against reoperation: HR 0.11(0.013 to 0.96, p=0.046). When inadequately fixed fractures were excluded differences in survival were no longer significant: reoperation (p=0.156); mechanical failure (p=0.453). Reoperation rates are higher following LLP-ORIF of low PDFFs compared to DFR. Where adequate reduction, proximal fixation and augmentation of medial comminution is used there is no difference in survival between LLP-ORIF and DFR

Aims. The aim of this study was to report a retrospective, consecutive series of patients with adolescent idiopathic scoliosis (AIS) who were treated with posterior minimally invasive surgery (MIS) with a mean follow-up of two years (. sd. 1.4; 0.9 to 0 3.7). Our objectives were to measure the correction of the deformity and record the peri-operative morbidity. Special attention was paid to the operating time (ORT), estimated blood loss (EBL), length of stay (LOS) and further complications. Patients and Methods. We prospectively collected the data of 70 consecutive patients with AIS treated with MIS using three incisions and a muscle-splitting approach by a single surgeon between June 2013 and February 2016 and these were retrospectively reviewed. There were eight male and 62 female patients with a mean age of 15 years (. sd. 4.5 ) with a mean body mass index of 19.8 kg/m. 2. (. sd. 5.4). The curves were classified according to Lenke; 40 curves were type 1, 15 were type 2, three were type 3, two were type 4, eight were type 5 and two were type 6. Results. The mean primary Cobb angle was corrected from 58.9° (. sd. 12.6°) pre-operatively to 17.7° (. sd.  10.2°) post-operatively with a mean correction of 69% (. sd. 20%, p < 0.001). The mean kyphosis at T5 to T12 increased from 24.2° (. sd. 12.2°) pre-operatively to 30.1° (. sd. 9.6°, p < 0.001) post-operatively. Peri-operative (30 days) complications occurred in three patients(4.2%): one subcutaneous haematoma, one deep venous thrombosis and one pulmonary complication. Five additional complications occurred in five patients (7.1%): one superficial wound infection, one suture granuloma and three delayed deep surgical site infections. The mean ORT was 337.1 mins (. sd. 121.3); the mean EBL was 345.7 ml (. sd. 175.1) and the mean LOS was 4.6 days (. sd. 0.8). Conclusion. The use of MIS for patients with AIS results in a significant correction of spinal deformity in both the frontal and sagittal planes, with a low EBL and a short LOS. The rate of peri-operative complications compares well with that following a routine open technique. The longer term safety and benefit of MIS in these patients needs to be evaluated with further follow-up of a larger cohort of patients. Cite this article: Bone Joint J 2017;99-B:1651–7

Bilateral one stage total knee replacement (TKR) has a number of advantages. There is one operative procedure and anesthetic and overall recovery time is significantly reduced. It is a more cost-effective procedure in that acute hospital stay is less and although rehabilitation time is greater in the short term, overall it is less. Additionally, if there is a bilateral flexion contracture present there is an inevitable loss of extension if a single knee is operated upon as this knee will assume the position of the unoperated knee. Patients greatly prefer having both knees corrected at one operative setting rather than having to have the inconvenience and pain associated with a second operative procedure at three to six months after the first one. There are potential disadvantages to a one stage procedure. One concern has been that there is more peri-operative morbidity associated with one stage bilateral total knee replacement. In a review of 501 patients undergoing bilateral one stage total knee replacement at the Hospital for Special Surgery (HSS) there were no peri-operative deaths, myocardial infarctions or cerebrovascular accidents. There were arrhythmias present in 5% of patients. Fat emboli were present in 3% and 2 patients (0.4%) had pulmonary emboli. The average transfusion requirement was 2.6 units and allogeneic blood was required in 42%. There were 2 deep infections, 3 hematomas and 5 patients with delayed wound healing There was an increased incidence of major complications in patients with ASA classification 3 and with increasing age over 70 years. New data indicates peri-operative administration of hydrocortisone may mitigate lung injury as demonstrated by reduction in cytokine and desmosine levels in a randomised trial. There was also a trend toward less need for narcotic medication and better range of motion in the steroid treated group. Patient selection is important and all patients are screened pre-operatively by an internist and anesthesiologist. In over 3000 bilateral TKRs at HSS infection rate and mortality were lower than in the unilateral total knee replacement patients. Much of this is due to patient selection criteria. All patients underwent the procedure with epidural anesthesia with post-operative epidural PCA for 48 hours. All patients are discharged on warfarin and spend the operative night in the recovery room. The procedure has acceptable morbidity and great advantage in properly selected patients

Aims

Due to the complex anatomy of the pelvis, limb-sparing resections of pelvic tumours achieving adequate surgical margins, can often be difficult. The advent of computer navigation has improved the precision of resection of these lesions, though there is little evidence comparing resection with or without the assistance of navigation.

Our aim was to evaluate the efficacy of navigation-assisted surgery for the resection of pelvic bone tumours involving the posterior ilium and sacrum.

Aims

The purpose of this article was to review the current literature pertaining to the use of mobile compression devices (MCDs) for venous thromboembolism (VTE) following total joint arthroplasty (TJA), and to discuss the results of data from our institution.

Total knee arthroplasty (TKA) is a cost effective and extremely successful operation. As longevity increases, the demand for primary TKA will continue to rise. The success and survivorship of TKAs are dependent on the demographics of the patient, surgical technique and implant-related factors.

Currently the risk of failure of a TKA requiring revision surgery ten years post-operatively is 5%.

The most common indications for revision include aseptic loosening (29.8%), infection (14.8%), and pain (9.5%). Revision surgery poses considerable clinical burdens on patients and financial burdens on healthcare systems.

We present a current concepts review on the epidemiology of failed TKAs using data from worldwide National Joint Registries.

Total knee replacement (TKR) is considered the “gold standard” treatment for advanced osteoarthritis (OA) of the knee with good survivorship and functional outcomes. However up to 20% of patients undergoing TKR may have unicompartmental disease only. Treatment options for medial compartment arthritis can include both unicompartmental knee replacements (UKR) and TKR. While some surgeons favor TKR with a proven track record, others prefer UKR due to more normal joint kinematics, better proprioception and better motion. There is also a higher rate of return to sports amongst patients with UKR compared to TKR. When considering all knee procedures, partial knee replacements account for 7–9%, primary TKRs for 83–88%, and revision knee replacements for 5–8%. Unicompartmental Knee Replacements comprise more than 90% of all partial knee replacement procedures. Proponents of UKR cite as advantages the preservation of normal knee kinematics, lower peri-operative morbidity, blood loss and infection risk compared with TKRs, as well as accelerated patient rehabilitation and recovery. However, partial knee replacements have a higher rate of revision than TKRs. This may be partly because they are inserted in patients with higher expectations, and partly because they are easier to revise. As a result, the volume of UKRs implanted has diminished over time and continues to decline. We compared patient reported outcomes, satisfaction and perception of normality of the knee post-operatively between UKR and TKR. A single unit and single surgeon series of patients were recruited. Data was collated for 68 well-matched patients with more than 24 months follow-up. UKR was undertaken in patients with isolated medial compartment osteoarthritis; stable ACL and less than grade 3 lateral patellar changes of the Outerbridge classification. TKR was undertaken for the rest. The patients were assessed with validated knee scores including the Total Knee Function Questionnaire (TKFQ) which focuses on recreational and sporting outcomes as well as activities of daily living (ADL). Patient satisfaction and perception of knee normality was measured on a visual analogue scale. Thirty-four patients with a TKR and 34 patients with a UKR were analyzed. The average ages in the TKR and UKR groups were 69.25 and 67.26 years, respectively. The patients were well-matched for demographics and had equivalent pre-operative morbidities and scores. The UKR group had better WOMAC (p=0.003), SF36 (physical: p<0.001 mental: p=0.25), Oxford knee (p<0.001) and Knee Society scores (p=0.002, function: p<0.001). The UKR group showed better outcomes in the TKFQ including exercise and sport (p= 0.02), movement and lifestyle (p=0.02) and the ADL (p=0.002). There was, however, no difference in patient satisfaction scores (p=0.41) and perception of how normal the knee felt between the two groups (p=0.99). A UKR procedure confers better functional outcome in terms of recreation and sport compared to TKR procedures. While UKR is an appropriate choice in the elderly yet active patient with unicompartmental knee arthritis, satisfaction is similar to that of patients with a TKR reflecting higher pre-operative expectations. We believe that in appropriate centers, the UKR procedure is associated with excellent outcomes. UKR should have a secure place in the knee arthroplasty armamentarium provided current knowledge regarding patient selection and surgical technique is followed

Obesity is clearly a worldwide epidemic with significant social, health care and economic implications. A clear association between obesity and the need for both hip and knee replacement surgery has been demonstrated. Specifically the presence of class 3 obesity (BMI > 40) increases the incidence of THA by 8.5 times and the incidence of TKA by 32.7 times, compared with patients of normal weight. Issues related to TJA in the morbidly obese include:. Outcomes - There is a growing body of evidence to support the premise that patients undergoing either THA or TKA who are morbidly obese derive significant benefit from the surgical intervention. Specifically patient and disease specific outcome measures (WOMAC, SF-12, KSCRS, HSS) demonstrate equal change between pre-operative and post-operative scores in those patients of normal weight compared to the morbidly obese cohort. Complications - It would appear that the rate of deep infection is increased in the morbidly obese, and that the greater the BMI, the greater the risk of infection. This is important to understand and appreciate pre-operatively as the surgeon discusses the risk/benefit ratio of the operative intervention. There is little debate that performing total joint arthroplasty in the morbidly obese is technically challenging and that the potential for increased peri-operative morbidity, particularly in the form of infection is present. That being said, the realised benefit to the patient of the surgical intervention is significant, and denying surgery on the basis of obesity alone is not justified

The August 2014 Knee Roundup³⁶⁰ looks at: re-admission following total knee replacement; out with the old and in with the new? computer navigation revisited; approach less important in knee replacement; is obesity driving a rise in knee replacements?; knee replacement isn’t cheap in the obese; cruciate substitution doesn’t increase knee flexion; and sonication useful diagnostic aid in two-stage revision.

It is a more cost effective procedure in that acute hospital stay is less and although rehabilitation time is greater in the short term overall it is less.

There were arrhythmias present in 5% of patients. Fat emboli were present in 3% and 2 patients (0.4%) had pulmonary emboli. The average transfusion requirement was 2.6 units and allogeneic blood was required in 42%. There were 2 deep infections, 3 hematomas and 5 patients with delayed wound healing. Average hospital stay was 7.2 days but this had decreased in the more recent patients. There was an increased incidence of major complications in patients with ASA classification 3 and with increasing age over 70 years. New data indicates peri-operative administration of hydrocortisone may mitigate lung injury as demonstrated by reduction in cytokine and desmosine levels in a randomised trial. Patient selection is important and all patients are screened pre-operatively by an internist and anesthesiologist.

Summary. Metastatic spinal disease is a common entity of much debate in terms of ideal surgical treatment. The introduction of MIS can be a game-changer in the treatment of MSD due to less peri-operative morbidity and allowing earlier radiotherapy and/or chemotherapy. Introduction. Less invasive techniques have always been welcome for management of patients with ‘Metastatic Spinal Disorders’. This is because these patients can be poor candidates for extensive / major invasive surgery even though radiologically, there may be an indication for one. The aim of the treatment with Minimal Invasive Fixation (MIS) systems is mainly for ‘pain relief’ than to radically decrease tumour burden or to achieve near total spinal cord decompression, which could be major presentations in these patients. These procedures address the ‘spinal instability’ very well and they can address pain associated with compression fractures resulting from metastatic disease from a solid organ as well as multiple myeloma with minimal complications. These procedures can be combined with radiology and chemotherapy without much concern for wound problems in the way of infection or dehiscence. They also have a great advantage of timing of adjunct therapy closer to the index procedure. The disadvantage, however, are they do not allow thorough decompression of the spinal cord. There could also be problem in addressing patients who have severe vertebral height loss or loss of integrity of the anterior column where anterior column reconstruction may be required. There is a risk of inadequate fixation or implant loosening or failure. We aim to examine the results of MIS surgery in our department and support the rationale for its use. Patients and Methods. We prospectively collected data of patients who underwent MIS posterior instrumentation for MSD. Between June 2011 and December 2012, 10 patients presented with acute motor deficit, instability and/or threatening radiological features. Effectiveness of MIS was assessed in terms of operative parameters and clinical outcomes. Results. No patient suffered intra-operative complications. The median surgical time was 198 minutes (range: 149 – 403), median blood loss was 100 ml (range: 60 – 400). All patients maintained full neurological function and reported effective pain reduction. All patients were discharged with a median hospital stay was 13 days (range: 4 – 45) post-surgery. 9 patients started oncological treatment as planned. The median time in 7 patients who had radiotherapy post-surgery was 23 days (range: 20 – 40). Chemotherapy was initiated in 4 patients at a median of 9 days post-surgery (range: 6 – 23). No patient as yet has required open procedure due to progression of the disease. Discussion/Conclusion. We have shown that satisfactory outcomes are achievable with MIS in a selected group of patients with MSD. While our results are limited by small study size, we have been able to improve patient quality of living through minimally invasive intervention. By reducing surgical morbidity and enabling early implementation of oncological treatment, MIS has the potential to re-evaluate multi-disciplinary decision making for early surgery in MSD

We describe 13 patients with cerebral palsy and lordoscoliosis/hyperlordosis of the lumbar spine who underwent a posterior spinal fusion at a mean age of 14.5 years (10.8 to 17.4) to improve sitting posture and relieve pain. The mean follow-up was 3.3 years (2.2 to 6.2). The mean pre-operative lumbar lordosis was 108. °. (80 to 150. °. ) and was corrected to 62. °. (43. °.  to 85. °. ); the mean thoracic kyphosis from 17. °. (-23. °. to 35. °. ) to 47. °. (25. °. to 65. °. ); the mean scoliosis from 82. °. (0. °. to 125. °. ) to 22. °. (0. °. to 40. °. ); the mean pelvic obliquity from 21. °. (0. °. to 38. °. ) to 3. °. (0. °. to 15. °. ); the mean sacral slope from 79. °. (54. °. to 90. °. ) to 50. °. (31. °. to 66. °. ). The mean pre-operative coronal imbalance was 5 cm (0 cm to 8.9 cm) and was corrected to 0.6 cm (0 to 3.2). The mean sagittal imbalance of -8 cm (-16 cm to 7.8 cm) was corrected to -1.6 cm (-4 cm to 2.5 cm). The mean operating time was 250 minutes (180 to 360 minutes) and intra-operative blood loss 0.8 of estimated blood volume (0.3 to 2 estimated blood volume). The mean intensive care and hospital stay were 3.5 days (2 to 8) and 14.5 days (10 to 27), respectively. Three patients lost a significant amount of blood intra-operatively and subsequently developed chest or urinary infections and superior mesenteric artery syndrome. An increased pre-operative lumbar lordosis and sacral slope were associated with increased peri-operative morbidity: scoliosis and pelvic obliquity were not. A reduced lumbar lordosis and increased thoracic kyphosis correlated with better global sagittal balance at follow-up. All patients and their parents reported excellent surgical outcomes. Lordoscoliosis and hyperlordosis are associated with significant morbidity in quadriplegic patients. They are rare deformities and their treatment is challenging. Sagittal imbalance is the major component: it can be corrected by posterior fusion of the spine with excellent functional results. Cite this article: Bone Joint J 2014;96-B:800–6

In the early days of total hip arthroplasty, the discussion of surgical approaches centered on issues related to obtaining optimum exposure for accurate insertion and fixation of implants and appropriate restoration of hip kinematics. More recently, attention has been directed to those aspects of exposure that appear to be associated with rapid recovery, shorter lengths of stay, less pain and minimal gait disturbance. The role of less invasive (“MIS”) exposures in achieving these outcomes has been sharply and extensively debated. Currently, the Direct Anterior Approach is being used by an increasing number of surgeons to address these outcomes. The purpose of this presentation is to discuss the relationship of total hip surgical approaches to peri-operative morbidity, rate of functional recovery, length of hospital stay and ultimate lower extremity function. Many factors affect the quality and rate of recovery from THA surgery. These include: 1) patient characteristics; 2) implant type; 3) surgical exposure and technique; and 4) peri-operative management. Numerous reports suggest that patient selection and effective peri-operative management have the greatest impact on the rate of recovery. The quality of the arthroplasty outcome is related to the accuracy with which the procedure is performed, regardless of the surgical approach used. Available evidence strongly suggests that the quality of the surgical technique used to perform a THA is a much more important determinant of outcome than the surgical approach used

Patient safety is a critical issue in elective total joint replacement surgery. Identifying risk factors that might predict complications and intensive care unit (ICU) admission proves instrumental in reducing morbidity and mortality. The institution’s experience with risk stratification and pre-operative ICU triage has resulted in a reduction in unplanned ICU admissions and post-operative complications after total hip replacement. The application of the prediction tools to total knee replacement has proven less robust so far. This work also reviews areas for future research in patient safety and cost containment.

Introduction:. Circumferential arthrodesis of the spine may be achieved by posterior-only or anterior and posterior surgery. Posterior-based interbody fusions have significant limitations including unreliable improvement of segmental lordosis and variable rates of post-operative radiculopathy. Combined anterior and posterior surgery introduces significant cost and peri-operative morbidity. The purpose of this paper is to report the radiographic and clinical outcomes of posterior-based circumferential arthrodesis using a novel expandable interbody cage. Methods:. A prospective pilot clinical trial with one year follow-up of the only expandable cage approved by the FDA for interbody application. Clinical outcomes measured include ODI and VAS for back and leg. Radiographic outcomes include arthrodesis rates based upon CT scan. Statistical significance for change in health status was calculated using Student's t-test. Results:. 10 consecutive patients (11 levels) with lumbar degenerative pathology underwent circumferential arthrodesis with a transforaminal interbody approach. 10 of 11 levels were fused based upon CT scan. ODI scores improved a median of 37 to 20 at 6 months and 17 at one year (p = 0.0003). The VAS for back and leg pain likewise from 6 to 2 at 12 months (p = −.003). No patient reported an increase in leg pain from pre-op to post-op. One patient with a 2-level fusion had a non-union at 1 level requiring revision surgery. Conclusion:. Circumferential arthrodesis with a TLIF approach is an important technique for the management of lumbar degenerative pathology. The experience with a novel expandable TLIF cage demonstrates excellent results based upon clinical outcome and fusion rates. The expandable interbody cage allows in-situ height increase which is useful for optimizing clinical and radiographic outcomes in TLIF surgery

Objectives

To determine the morbidity and mortality outcomes of patients presenting with a fractured neck of femur in an Australian context. Peri-operative variables related to unfavourable outcomes were identified to allow planning of intervention strategies for improving peri-operative care.
