Abstract. Objective. Meta-analysis of clinical trials highlights that non-operative management of degenerative knee meniscal tears is as effective as surgical management. Surgical guidelines though support arthroscopic partial meniscectomy which remains common in NHS practice. Physiotherapists are playing an increasing role in triage of such patients though it is unclear how this influences clinical management and patient outcomes. Methods. A 1-year cohort (July 2019–June 2020) of patients presenting with MRI confirmed degenerative meniscal tears to a regional orthopaedic referral centre (3× ESP physiotherapists) was identified. Initial clinical management was obtained from medical records alongside subsequent secondary care management and routinely collected outcome scores in the following 2-years. Management options included referral for surgery, conservative (steroid injection and rehabilitation), and no active treatment. Outcome scores collected at 1- and 2-years included the Forgotten Joint Score-12 (FJS-12) questionnaire and 0–10 numerical rating scales for worst and average pain. Treatment allocation is presented as absolute and proportional figures. Change in outcomes across the cohort was evaluated with repeated measures ANOVA, with Bonferroni correction for multiple testing, and post-hoc Tukey pair-wise comparisons. As treatment decision is discrete, no direct contrast is made between outcomes of differing interventions but additional explorative outcome change over time evaluated by group. Significance was accepted at p=0.05 and effect size as per Cohen's values. Results. 81 patients, 50 (61.7%) male, mean age 46.5 years (SD13.13) presented in the study timeframe. 32 (40.3%) received conservative management and 49 (59.7%) were listed for surgery. Six (18.8%) of the 32 underwent subsequent surgery and nine of the 49 (18.4%) patients switched from planned surgery to receiving non-operative care. Two post-operative complications were noted, one cerebrovascular accident and one deep vein thrombosis. The cohort improved over the course of 2-years in all outcome measures with improved mean FJS-12 (34.36 points), mean worst pain (3.74 points) average pain (2.42 points) scores. Overall change (all patients) was statistically significant for all outcomes (p<0.001), with sequential year-on-year change also significant (p<0.001). Effect size of these changes were large with all Cohen-d values over 1. Controlling for age and BMI, males reported superior change in FJS-12 (p=0.04) but worse pain outcomes (p<0.03). Further explorative analysis highlighted positive outcomes across all surgical, conservative and no active treatment groups (p<0.05). The 15 (18%) patients that switched between surgical and non-surgical management also reported positive outcome scores (p<0.05). Conclusion(s). In a regional specialist physiotherapy-led soft tissue knee clinic around 60% of degenerative meniscal tears assessed were referred for surgery. Over 2-years, surgical, non-operative and no treatment management approaches in this cohort all resulted in clinical improvement suggesting that no single strategy is effective in directly treating the meniscal pathology, and that perhaps none do. Clinical intervention rather is directed at individual symptom management based on clinical preferences. Declaration of Interest.

Introduction The 2002 NCEPOD report recommended that autopsies should be the subject of a formal external audit process. It is thought that a post mortem would improve the understanding of the pathological events leading up to the death of a patient. The aims of this study were to find out the number of post mortems requested for patients with hip fracture and to establish the cause of death of all hip fracture patients as documented on the death certificate by medical practitioners and the coroner. Patients and Methods A retrospective review of all hip fracture deaths in the year 2000 was performed. The number of cases referred to the coroner for a post mortem and the given verdict was documented. Data regarding the cause of death (as per part 1a on the death certificate) recorded by the medical practitioner and the coroner was established. Results 83 patients with a hip fracture died in hospital in 2000 (mean age 83.6 years, range 58–97 years). There were 30 male and 53 female deaths. 37 patients (44.6%) were referred to the coroner for a post mortem examination. The common causes of death documented by the medical practitioner were: Bronchopneumonia; 27.9%, Congestive cardiac failure; 11.6%, Left ventricular failure; 9.3%, Cerebrovascular accident; 14%, and Carcinomatosis; 4.6%. The common causes of death documented by the coroner were: Bronchopneumonia; 35.1%, Congestive cardiac failure; 16.2%, Left ventricular failure; 10.8%, Cerebrovascular accident; 2.7%, carcinomatosis; 8.1%, and Pulmonary embolism; 8.1%. Conclusion Approximately 45% of hip fracture deaths are referred to the coroner. Apart from PE, the cause of death documented by medical practitioners and the coroner was no different in terms of frequency and spectrum. Cardiac and respiratory causes account for nearly 2/3 of hospital hip fracture deaths. Resources need to be targeted accordingly in an attempt to improve in hospital morbidity and mortality

Aim. Left sided hip fractures are more common but no obvious cause has been identified. Left handedness has previously been associated with an increased risk of fracture for a number of sites but to the best of our knowledge no association between handedness and hip fracture has previously been reported. Methods. 2 separate 6-month prospective reviews of hip fracture patients aged over 65 years-of-age were conducted at 2 different hospitals. Handedness was dete2rmined at the time of admission. The second review focused on the use of walking aids. Patients with a previous cerebrovascular accident, neurological condition or contralateral hip prosthesis were excluded due to increased balance problems and falls risk. Results. Hand dominance was recorded for 339 patients; 304 right and 35 left. 91 patients were excluded. Of the remaining 248 patients more than twice as many (2.06 times) fractured their hip on the side of their non-dominant hand. For left handed individuals this increased to 4.6 times. Walking aid use was recorded for 102 patients. For patients using no walking aids, a Zimmer frame or 2 walking sticks; equal numbers of patients sustained right and left hip fractures. While 97.7% of patients using 1 walking stick did so in their dominant hand, sustaining 84% contralateral hip fractures. Conclusions. The direction in which people fall and the causes of hip fractures are clearly multi-factorial. However there is a clear association between hand dominance and the side of hip fracture, particularly in left handed individuals. Walking aids also play a role with 97.7% of patients using a walking stick in their dominant hand resulting in 84% contralateral hip fractures. By being aware of this association it may be possible to target both patient education and physiotherapy potentially reducing the number of patient falls and associated hip fractures

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

Hip fractures are among the most common orthopaedic injuries and represent a growing burden on healthcare as our population ages. Despite improvements in preoperative optimisation, surgical technique and postoperative care, complication rates remain high. Time to surgery is one of the few variables that may be influenced by the medical team. The aim of the present study was to evaluate the impact of time to surgery on mortality and major complications following surgical fixation of hip fractures. Utilising the American College of Surgeons' National Quality Improvement Program (NSQIP) database, we analysed all hip fractures (femoral neck, inter-trochanteric, and sub-trochanteric) treated from 2011 to 2013 inclusively. We divided patients into three groups based on time to surgery: less than one day (<24h), one to two days (24–48h), and two to five days (48–120h). Baseline characteristics were compared between groups and a multivariate analysis performed to compare 30-day mortality and major complications (return to surgery, deep wound infection, pneumonia, pulmonary embolus, acute renal failure, cerebrovascular accident, cardiac arrest, myocardial infarction, or coma) between groups. A total of 14,730 patients underwent surgical fixation of a hip fracture and were included in our analysis. There were 3,475 (24%) treated <24h, 9,960 (67%) treated 24–48h, and 1,295 (9%) treated 48–120h. Thirty-day mortality and major complication rates were 5.0% and 6.2% for the <24h group, 5.3% and 7.0% for the 24–48h group, 7.9% and 9.7% for the 48–120h group respectively. After controlling for baseline demographic differences between groups (age, sex, race) as well as pertinent comorbidities (diabetes, dyspnea, chronic obstructive pulmonary disease, chronic steroid use, hypertension, cancer, bleeding disorders, and renal failure), time to surgery beyond 48h resulted in greater odds of both mortality (1.45, 95%CI 1.10–1.91) and major complications (1.45, 95%CI 1.12–1.84). Time to surgery is one of the few variables that can be influenced by timely medical assessment and access to the operation room. Expediting surgery within 48h of hip fracture is of paramount importance as it may significantly reduce the risk of mortality as well as major complications

To progress to a same day surgery program for arthroplasty, it is important that we examine and resolve the issues of why patients stay in the hospital. The number one reason is fear and anxiety of the unknown and of surgical pain. The need for hospital stay is also related to risk arising from comorbidities and medical complications. Patients also need an extended stay to manage the side effects of our treatment, including after effects of narcotics and anaesthesia, blood loss, and surgical trauma. The process begins pre-operatively with an appropriate orthopaedic assessment of the patient and determination of the need for surgery. The orthopaedic team must motivate the patient, and ensure that the expectations of the patient, family and surgeon are aligned. In conjunction with our affiliated hospitalist group that performs almost all pre-admission testing, we have established guidelines for patient selection for outpatient arthroplasty. The outpatient surgical candidate must have failed conservative measures, must have appropriate insurance coverage, and must be functionally independent. Previous or ongoing comorbidities that cannot be optimised for safe outpatient care may include: congestive heart failure, or valve disease; chronic obstructive pulmonary disease, or home use of supplemental oxygen; untreated obstructive sleep apnea with a BMI >40 kg/m2; hemodialysis or severely elevated serum creatinine; anemia with hemoglobin <13.0 g/dl; cerebrovascular accident or history of delirium or dementia; and solid organ transplant. Pre-arthroplasty rehabilitation prepares the patient for peri-operative protocols. Patients meet with a physical therapist and are provided with extensive educational materials before surgery to learn the exercises they will need for functional recovery. Enhancement of our peri-operative pain management protocols has resulted in accelerated rehabilitation. The operative intervention must be smooth and efficient, but not hurried. Less invasive approaches and techniques have been shown to decrease pain, reduce length of stay, and improve outcomes, especially in the short term. Between June 2013 and December 2015, 1957 primary knee arthroplasty procedures (1010 total, 947 partial) were performed by the author and his 3 associates at an outpatient surgery center. Seven percent of patients required an overnight stay, with a majority for reasons of convenience related to travel distance or later operative time. Importantly, no one has required overnight stay for pain management. Outpatient arthroplasty is safe, it's better for us and our patients, and it is here now. In an outpatient environment the surgeon actually spends more time with the patients and family in a friendly environment. Patients feel safe and well cared for, and are highly satisfied with their arthroplasty experience

Bilateral one-stage total knee replacement 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.

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 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. 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.

Arthritis of the hip is a relatively common problem in patients with neuromuscular disorders due to muscle imbalance around the hip from weakness, paralysis, contractures and spasticity. Neuromuscular disorders such as cerebral palsy, Parkinson's disease, poliomyelitis, previous cerebrovascular accident (CVA) and Charcot arthropathy have been considered by many to be contraindications to total hip arthroplasty (THA). The presence of certain anatomic abnormalities (excessive femoral anteversion, acetabular dysplasia, leg length discrepancy (LLD) and coax valga) and significant soft tissue contractures, muscle imbalance, and muscular weakness make THA a challenging surgical procedure in this patient population, and can predispose to dislocation and poor functional outcome following surgery. THA can, however, result in substantial pain relief and functional improvement, and can be safely performed, provided certain technical considerations are addressed. The patient's motor strength and functional status (ambulatory vs. “sitter”) should be carefully assessed preoperatively, since both of these factors may affect the choice of surgical approach and component position. Significant soft tissue contractures should be released at the time of surgery. Although these can be frequently performed “open”, percutaneous adductor tenotomy is occasionally necessary for patients with significant adduction contractures. Patients requiring significant soft tissue releases may benefit from 6 weeks of bracing to allow soft tissues to heal in appropriately and minimise risk of dislocation during this period of time. Use of modular femoral components that allow for correction of excessive femoral anteversion, should be considered in patients with coexistent dysplasia and neuromuscular disease (i.e., CP or polio). Large femoral head components should also be considered in patients with increased risk factors for dislocation. Despite their obvious theoretical advantages, the use of large head metal on metal THAs should be used with extreme caution in view of growing concerns about these devices. Although constrained acetabular liners are associated with an increased risk of mechanical failure, their use should be strongly considered in patients with significant motor weakness or major soft tissue deficiencies. Meticulous soft tissue closure of the capsule of the hip is recommended, especially when performing THA through a posterior approach. Patients with neuromuscular disorders associated with spasticity and involuntary movements need to be optimally treated medically prior to and indefinitely after THA. There are limited reports of outcomes following THA in patients with neuromuscular disorders, however, some generalizations based on underlying diagnosis can be made. Patients with cerebral palsy and polio frequently have acetabular dysplasia, excessive femoral anteversion and LLD, and although durability does not seem to be a major concern, dislocation and instability is relatively common and needs to be addressed. Durability and instability do not appear to be major concerns in patients with Parkinson's disease, however, these patients have frequent medical complications perioperatively and have deterioration in function over time due to the progressive nature of their underlying disorder. Patients with previous CVA also appear to have acceptable durability and dislocation risk, but are at high risk of developing heterotopic ossification postoperatively. Patients with Charcot arthropathy or myelodysplasia are at high risk of instability and appear to have limited functional improvement following THA. As a result, the consensus of opinion is that THA is contraindicated in these patients

Introduction. A fractured hip is the commonest cause of injury related death in the UK. Prompt surgery has been found to improve pain scores and reduce the length of hospital stay, risk of decubitus ulcer formation and mortality rates. The hip fracture Best Practice Tariff (BPT) aims to improve these outcomes by financially compensating services, which deliver hip fracture surgery within 36 hours of admission. Ensuring that delays are reserved for patients with conditions which compromise survival, but are responsive to medical optimisation, would facilitate enhanced outcomes and help to achieve the 36-hour target. We aimed to identify medical conditions associated with patients failing to achieve the 36-hour cut off, and evaluated whether these were justified by calculating their associated mortality risk. Methods. Prospectively collected data from the National Hip Fracture Database (NHFD) and inpatient hospital records and blood results from a single major trauma centre were obtained. Complete data sets from 1361 patients were available for analysis. Medical conditions contributing to surgical delay beyond the BPPT (Best Practice Tariff Target) 36-hour cut off, were identified and analysed using univariate and multivariate regression analyses, whilst adjusting for covariates. The mortality risk associated with each factor contributing to surgical delay was then calculated using univariate and hierarchical regression techniques. Results. A total 1,361 patients underwent hip fracture surgery, of which 537 patients (39.5%) received surgery within 36- hours of admission. The overall median time to surgery from presentation was 23 hours (range 3–36) in patients who did (group 1) and 72 hours (range 36–774) in those who did not (group 2) receive timely surgery. There was no difference between the two groups with respect to age, gender, walking ability, fracture pattern and ASA grade. Following univariate analysis, seven variables including admission source, history of dementia, ischaemic heart disease, MI, cerebrovascular accidents (CVA), urinary tract infections and hyponatraemia met criteria for inclusion into the Cox regression model. The model thereafter revealed only hyponatraemia to be a significant determinant of delay to surgery beyond 36 hours with a covariate adjusted relative risk (RR) 1.24 (95% CI 1.06 – 1.44, p=0.006). The overall 30- day mortality in our cohort of hip fracture patients was 9.0%. The commonest cause of death was pneumonia (37%). A second stage hierarchical cox model failed to demonstrate hyponatraemia as being a predictor of 30- day mortality after adjusting for significant co-variants (RR=0.944, CI 95% 0.616–1.447, p=0.793). Conclusions. Hip fracture surgery should not be delayed in the presence of non-severe and isolated hyponatraemia. Instead surgical delay should be reserved for medical conditions, which contribute to mortality and are optimisable

To progress to a same day surgery program for arthroplasty, it is important that we examine and resolve the issues of why patients stay in the hospital. The number one reason is fear and anxiety for the unknown and for surgical pain. The need for hospital stay is also related to risk arising from comorbidities and medical complications. Patients also need an extended stay to manage the side effects of our treatment, including after-effects of narcotics and anesthesia, blood loss, and surgical trauma. The process begins pre-operatively with an appropriate orthopaedic assessment of the patient and determination of the need for surgery.

The outpatient surgical candidate must have failed conservative measures, must have appropriate insurance coverage, and must be functionally independent. Previous or ongoing comorbidities that contraindicate the outpatient setting include: cardiac – prior revascularization, congestive heart failure, or valve disease; pulmonary – chronic obstructive pulmonary disease, or home use of supplemental oxygen; untreated obstructive sleep apnea – BMI >40 kg/m2; renal disease – hemodialysis or severely elevated serum creatinine; gastrointestinal – history or post-operative ileus or chronic hepatic disease; genitourinary – history of urinary retention or severe benign prostatic hyperplasia; hematologic – chronic Coumadin use, coagulopathy, anemia with hemoglobin <13.0 g/dl, or thrombophilia; neurological – history of cerebrovascular accident or history of delirium or dementia; solid organ transplant. Pre-arthroplasty rehabilitation prepares the patient for peri-operative protocols. Patients meet with a physical therapist and are provided with extensive educational materials before surgery to learn the exercises they will need for functional recovery. Enhancement of our peri-operative pain management protocols has resulted in accelerated rehabilitation. The operative intervention must be smooth and efficient, but not hurried. Less invasive approaches and techniques have been shown to decrease pain, reduce length of stay, and improve outcomes, especially in the short term. In 2014, 385 primary partial knee arthroplasty procedures (7 patellofemoral replacement, 13 lateral, and 365 medial) were performed by the author and his 3 associates at an outpatient surgery center. Of those, 348 (95%) went home the same day while 17 (5%) required an overnight stay, with 11 for convenience related to travel distance or later operative time and 6 for medical issues. Outpatient arthroplasty is safe, it's better for us and our patients, and it is here now. In an outpatient environment the surgeon actually spends more time with the patients and family in a friendly environment. Patients feel safe and well cared for, and are highly satisfied with their arthroplasty experience

Fractures of the femoral neck in the elderly are associated with significant morbidity and mortality. In the UK, patients with these fractures occupy 20% of orthopaedic beds. Between September 1999 and August 2000 a prospective study was conducted to evaluate the outcome in 36 patients, 24 of them women, with femoral neck fractures treated by uncemented Thompson’s hemi-arthroplasty. The mean age of patients was 71.6 years. All patients had sustained a Garden type-III or IV fracture, and 89% were due to low velocity trauma. Associated conditions were hypertension (66%), diabetes mellitus (27%), dementia (22%), ischaemic heart diseases (16%), cerebrovascular accident (16%), asthma (16%), alcoholism, epilepsy and malignancies (5% each). Before the injury, 55% of patients walked normally, while 19% had a limp and 28% were using a walking aid. At the time of injury 67% were living with family, 22% independently and 11% in a nursing home. Surgery was performed under spinal anaesthetic at a mean of 12.5 days (3 to 30) after injury. None of the patients received prophylactic treatment for deep vein thrombosis. Postoperative mobilisation was commenced at 48 hours, and patients were discharged a mean of 5.5 days (2 to 28) postoperatively to nursing homes (27.5%), family (27.5%) or independent living (16.5%). In the first month after surgery 27.5% of patients died. At six months 14% of patients had normal mobility, while 25% had a limp, 30% used a walking aid and 3% were wheelchair-bound. The overall results in this study are comparable with those in the literature. The delay in surgery did not affect morbidity or mortality

Arthritis of the hip is a relatively common problem in patients with neuromuscular disorders due to muscle imbalance around the hip from weakness, paralysis, contractures and spasticity.

As a result, the consensus of opinion is that THA is contraindicated in patients with Charcot arthropathy and myelodysplasia

Despite advances in Locking Plate (LP) design, distal femoral fractures remain challenging injuries to treat especially in the elderly where approximately 15–30% develop nonunions secondary to failure of fixation. Aim: To establish the mechanisms of nonunion in our patient population using two different LP systems. Methods: Between December 2002-May 2008, we prospectively collected data on all 67 patients with distal femoral fractures who were treated using a suitable distal femoral LP (LISS, 35 cases, or Periloc, 32 cases). 72% of the patients were female; ages ranged from 25–94 years (ave. 67 years). Many of our patients had a number of significant co-morbidities. Results: The presence of significant co-morbities e.g. Rheumatoid arthritis, long term systemic steroid use, cerebrovascular accidents resulting in ambulatory problems, previous major joint arthroplasty including ipsilateral knee replacements, paralysis, and severe dementia, did not appear to influence fracture union significantly. However, old age was strongly correlated with nonunion with all failed cases (7 patients - 10% of the study group) presenting with failure of fixation. 2 of the LP system failures resulted in malunion and the 5 other cases required revision surgery. Of note, all 7 patients were elderly, 6 being over 80 years of age. The mechanism of fixation failure was specific to each of the LP systems. All 4 of the failures treated with LISS, resulted from poor proximal stability as a consequence of unicortical screw fixation. Two patients required to have the proximal fixation revised through the insertion of bicortical screws which subsequently resulted in successful union. The other two patients were treated in long leg casts as the varus deformities were considered acceptable given each patient’s needs. All 3 of the failures who had been treated with a Periloc LP, resulted from fracturing of the plate at the metaphyseo-diaphyseal junction at the level of the main extra-articular component of the fracture. The plates all fractured through the unfilled screw holes, and all 3 patients required revision of fixation to bring about union. Discussion: The LISS failures can all be attributed to poor proximal fixation that is associated with the use of unicortical screws in osteoporotic bone and confirms the need for bicortical screw fixation. However, modern LP systems manufactured from stainless steel offer increased implant stability that may in turn stress any fracture bridging segments of the LP. Conclusion: Although we are aware of the importance of bicortical screws in osteoporotic patients, it is also seems likely that excessive plate rigidity should be avoided, by using long plates with well spaced out screws

Objective: To assess the safety and outcome of laminectomy in patients with spinal stenosis operated at the age of 65 years or older. The relation between the duration of the symptoms and results was investigated. Study Design: A retrospective chart analysis with up to 10 years follow-up. Setting: The Spinal Care Unit, Meir Medical Center, Kfar Saba, Israel. Material and Methods: The medical records of all patients who had laminectomy for spinal stenosis at the age of 65 or more in a 10 years period were reviewed. Assessment of pain, ability to perform the basic activities of daily living, transferring dressing and basing before and after the operation was done by a telephone interview. Patient’s self-estimation of the final result of the surgery was also recorded. Results: Two hundred eight-three patients were eligible to participate in the study. They were allocated into 3 groups according to the duration of symptoms before surgery. Group A with symptoms lasting up to 24 months, B with 25–48 months and C with symptoms lasting for more than 48 months. The average age at the time of the operation was 68.9, 72.6 and 71.3 years, respectively. Forty-eight patients died and 18 refused or were not able to participate in the study. The average time of follow-up was 43.3 months, 42.2 in group A, 47.4 in B and 42.8 in C. No significant differences were noticed in the demographic, anesthetic and surgical parameters among the 3 groups. There were no mortality cases in the immediate postoperative period. The overall complication rate was 43.5%, nearly identical in all 3 groups. Two patients had cerebrovascular accident and 5 had myocardial ischemia but no one turned into infarction. Mild complications included 11 urinary retention, 24 urinary tract infections and 11 patients with superficial wound infection. Twenty-two patients were re-operated along the follow-up period. There was remarkable improvement in the perception of pain, walking distances and in the ability to perform basic activities of daily living in all 3 groups. Self-assessment of the final results disclosed 70% satisfied patients in group A, 67% in B and 67% in C. Conclusion: Surgery for spinal stenosis in elderly patients is safe and often lead to significant relief of pain and improvement in the quality of life. Delaying surgery had no deleterious effect on the operative results

This study examines patient characteristics, indications for conversion, surgical and anaesthetic technique, peri-operative management and complications of surgery in this small and challenging group of patients. In the six years from 1994 to 1999, 33 conversion arthroplasties were performed for failed femoral hemiarthroplasty. The average age at conversion surgery was 75.5 years (range 65–90). The female to male ratio was 6:1. Primary hemiarthroplasties comprised 24 Austin-Moore, 6 Thompson & 3 Bipolar prostheses. The average interval from primary to conversion surgery was 50 months (6 months to 17 years). The average age at primary surgery was 71.2 years (62–88) – AMP:71.4 years, Thompson’s: 74.2 years, Bipolar: 63.5 years. All hemiarthroplasties were performed for fractured femoral necks. 62% of patients came from the Eastern Health Board area, while 38% were tertiary are referrals from other Health Boards. The average length of stay was 17.5 days (3–24). Indications for conversion included gross loosening/acetabular erosion in 9 cases, suspected infection in 4 cases and abscess/septicaemia in 1 case. All but 3 patients had significant pain (night pain etc.) and/or severely impaired mobility. We also looked at anaesthetic and analgesic practice, surgical technique and prostheses used. Post-operatively, mean total blood loss was 1430 ml (420–2280) with an average of 1.4 units of blood transfused (0–5). Intraoperative complications included acetabular & femoral perforation, periprosthetic fracture and cement reactions. Complications post-op (in hospital) included cardiac arrhythmia’s, cerebrovascular accidents, pulmonary embolus, myocardial infarct, respiratory & urinary tract infections, constipation, nausea & vomiting. The elderly nature of these patients and the physiological stress of what is major surgery allied with multiple co-morbidities make their care especially challenging. A conversion arthroplasty is a procedure with a significant risk of considerable morbidity. Primary total hip replacement or bipolar hemiarthroplasty are options which, therefore, should be seriously considered in the case of fractured femoral necks to minimise the need for further surgery in the future, with all its attendant risks

Arthritis of the hip is a relatively common problem in patients with neuromuscular disorders due to muscle imbalance around the hip from weakness, paralysis, contractures and spasticity. Neuromuscular disorders such as cerebral palsy, Parkinson's disease, poliomyelitis, previous cerebrovascular accident (CVA) and Charcot arthropathy have been considered by many to be relative contraindications to total hip arthroplasty (THA). The presence of certain anatomic abnormalities (excessive femoral anteversion, acetabular dysplasia, leg length discrepancy (LLD) and coax valga) and significant soft tissue contractures, muscle imbalance, and muscular weakness make THA a challenging surgical procedure in this patient population, and can predispose to dislocation and poor functional outcome following surgery. THA can, however, result in substantial pain relief and functional improvement in patients with significant hip arthritis and neuromuscular disorders, and can be safely performed, provided certain technical considerations are addressed. The patient's motor strength and functional status (ambulatory vs. “sitter”) should be carefully assessed pre-operatively, since both of these factors may affect the choice of surgical approach and component position. Significant soft tissue contractures should be released at the time of surgery. Although these can be frequently performed “open,” percutaneous adductor tenotomy is occasionally necessary for patients with significant adduction contractures. Patients requiring significant soft tissue releases may benefit from 6 weeks of bracing to allow soft tissues to heal in appropriately and minimize risk of dislocation during this period of time. Use of modular femoral components that allow for correction of excessive femoral anteversion, should be considered in patients with coexistent dysplasia and neuromuscular disease (i.e. CP or polio). Large femoral head components should also be considered in patients with increased risk factors for dislocation. Despite their obvious theoretical advantages, the use of large head metal on metal THAs should be used with extreme caution in view of growing concerns about these devices. Although constrained acetabular liners are associated with an increased risk of mechanical failure, their use should be strongly considered in patients with significant motor weakness or major soft tissue deficiencies. Meticulous soft tissue closure of the capsule of the hip is recommended, especially when performing THA through a posterior approach. Patients with neuromuscular disorders associated with spasticity and involuntary movements need to be optimally treated medically prior to and indefinitely after THA. There are limited reports of outcomes following THA in patients with neuromuscular disorders, however some generalisations based on underlying diagnosis can be made. Patients with cerebral palsy and polio frequently have acetabular dysplasia, excessive femoral anteversion and LLD, and although durability does not seem to be a major concern, dislocation and instability is relatively common and needs to be addressed. Durability and instability do not appear to be major concerns in patients with Parkinsons disease, however, these patients have frequent medical complications perioperatively and have deterioration in function over time due to the progressive nature of their underlying disorder. Patients with previous CVA also appear to have acceptable durability and dislocation risk, but are at high risk of developing heterotopic ossification post-operatively. Patients with Charcot arthropathy or myelodysplasia are at high risk of instability and appear to have limited functional improvement following THA. As a result, the consensus of opinion is that THA is contraindicated in patients with Charcot arthropathy and myelodysplasia

Aims

To map literature on prognostic factors related to outcomes of revision total knee arthroplasty (rTKA), to identify extensively studied factors and to guide future research into what domains need further exploration.

Aims

The primary aim was to assess whether preoperative health-related quality of life (HRQoL) was associated with postoperative mortality following total hip arthroplasty (THA) and knee arthroplasty (KA). Secondary aims were to assess whether patient demographics/comorbidities and/or joint-specific function were associated with postoperative mortality.

This study was designed to prospectively evaluate the efficacy of indomethacin as prophylaxis for heterotopic ossification (HO) after operatively treated acetabular fractures. An IRB approved, prospective double blind placebo controlled clinical trial was performed at two level I trauma centres to evaluate the efficacy of indomethacin as prophylaxis for heterotopic ossification after the operative treatment of acetabular fractures. Between January 1, 1999 and May 31, 2003, two hundred and thirty-two patients with acetabular fractures were treated operatively through a posterior approach. Patients with the following conditions were excluded from study participation: age < 18, spinal cord injury, ankylosing spondylitis, burns, gastrointestinal bleed, Glasgow coma scale < 12, cerebrovascular accident, pregnancy and use of other non-steroidal anti-inflammatory drugs. One hundred and fifty-seven eligible patients were identified and one hundred and twenty-five patients were enrolled in the clinical trial. One hundred and seven patients have sufficient follow up to be included in data analysis. All patients underwent operative stabilization of their ace-tabular fractures by either a combined anterior and posterior approach or an isolated posterior Kocher-Lan-genbock approach. After fixation and prior to wound closure, any necrotic gluteus minimus muscle was debrided to viable muscle. Sixty-one patients were randomized to the placebo group and forty-six patients to the indomethacin treatment group. Indomethacin 75 mg SR and the placebo were administered to the patients by the investigational drug pharmacy in a blinded fashion. The medication was taken once daily for six weeks. Patient compliance was measured by obtaining indomethacin serum levels at the first postoperative visit (2 weeks). The extent of HO was evaluated on plain radiographs (AP and Judet) at three months postoperatively. The radiographs were scored for the presence of HO using the Brooker classification as modified by Moed. The data were analyzed two ways: 1) by excluding patients with protocol deviations and 2) by using an intent-to-treat model, where all enrolled subjects with 3 month Brooker scores were included in the analysis, regardless of whether they withdrew or were dropped from the study for clinical reasons. The sample size was estimated to produce a statistical power of 80% to detect a difference of 15% between the two treatment groups with alpha = .05. There were no significant differences with regards to age, sex, body mass index (BMI), ISS (injury severity score) and complications between the two treatment groups. The overall incidence of HO (Brooker I-IV) was 52.8% and the overall incidence of significant HO (Brooker III/IV) was 19.6%. There were four patients with Brooker IV HO. There was no significant difference between the treatment groups in the incidence of HO according to Brooker class (p=0.23). Significant HO (Brooker grades III-IV) occurred in 8 cases (17%) in the indomethacin group and 13 cases (21%) in the placebo group. There was no significant difference in the presence of moderate to severe HO (Brooker III/IV) between the two treatment groups (Fisher’s exact test p=0.81). Eighty-two of one hundred and seven patients enrolled completed the protocol. Twenty-five patients did not complete the treatment protocol for the following reasons: stopped medication due to side effects, did not receive medication at discharge, lost medication, or medication stopped by another physician who did not understand the purpose of the study. Nine patients (8.4%) did not receive the full medication course, sixteen patients (15%) were dropped or withdrew from the study for adverse events or gastrointestinal symptoms. Twelve patients dropped or withdrew from the indomethacin group and three from the placebo group. Forty percent of patients in the indomethacin group had non-detectable serum levels at two weeks. Complications identified in the indomethacin treatment group included deep venous thrombosis (5), wound infection (2), nonunion (1), gastrointestinal bleed (1) and perforated ulcer (1). Complications identified in the placebo group included deep venous thrombosis (6) and wound infection (2). In this prospective randomized study, a placebo provided as effective prophylaxis against the development of heterotopic ossification as indomethacin. More patients withdrew from the indomethacin group for gastrointestinal side effects or adverse events than in the placebo group. Patient compliance with indomethacin was poor with 40% of patients having no detectable indomethacin serum level. Serious gastrointestinal complications (gastrointestinal bleed and perforated ulcer) occurred in two patients treated with indomethacin
