Abstract. Background. The primary objective of the study is to determine the function outcome and survivorship of patellofemoral replacement. The secondary aim is to find the determinants of successful/poor outcome. Methods. This retrospective study involved 45 patients who underwent AVON patellofemoral replacement between January 2015 to December 2020 with the minimal follow-up off for 12 months. The functional outcome was measured using Oxford Knee score (OKS), EuroQol five dimension (EQ-5D). IWANO and Kellgren-Lawrence classification was used to analyse radiographs. To identify determinants of outcome, the following subgroups the presence or absence of normal alignment, tibiofemoral arthritis, trochlear dysplasia and previous surgery. Complications and revision rates were also recorded. Results. The mean follow-up period was 41.7 +/− 8.3 months with no patients lost in follow-up. Patellofemoral replacement significantly improved the Oxford Knee score (OKS), EuroQol five dimension (EQ-5D) (p<0.001). Four out of 45(8.9%) patients underwent revision surgery. Patients with normal alignment preoperatively did worse than those with abnormal alignment with patellar instability. Patients with grade two tibiofemoral arthritis, history of previous surgery did significantly worse with poorer functional outcome. Conclusion. Patellofemoral arthroplasty is reliable treatment option which improves patient function and quality of life with good survivorship in isolated patellofemoral arthritis in mid-term follow-up

Abstract. INTRODUCTION. Fracture neck of femur is aptly called as “the fracture of necessity” owing to the various factors responsible for its non-union. Pauwel's inter-trochantric valgus osteotomy is a useful approach to deal with such fractures. AIM. The aim of this study is to evaluate the functional outcome of valgus osteotomy in treatment of neglected and non-union fracture neck of femur using Harris Hip Scoring system (HHS). MATERIAL AND METHODS. This observational study included 25 patients of the age between 25 years and 50 years with more than 3 weeks since injury and the patients with failed primary fixation. Valgus osteotomy using120° double angled blade plate was done. The patients were followed up till one year. The patients' functional outcome was evaluated with pre-operative and post-operative Harris Hip Score (HHS) at 6 months and one year. RESULTS. Outcome was excellent in 14 patients (HHS>90), good in 8 patients (HHS between 80–90) and fair in one patient (HHS=75.6). Two patients ended up in non-union with blade cut out. The mean HHS at the end of one year was 89.18 + 7.822. The mean change in HHS values pre-operatively and one year post-operatively came out to be 69.58 + 20.032. CONCLUSION. We conclude that for the patients under 50 years of age with neglected fracture of the femoral neck, the Pauwel's osteotomy produces many good results

Abstract. Objectives. This study aims to evaluate the functional outcomes of early weight-bearing in a functional orthosis for conservatively managed, complete AT ruptures. Also we tried to evaluate the patient reported outcome with this form of treatment. Design. In this prospective study, we have analysed data from 41 patients with ultrasound diagnosed compete AT ruptures, with a gap of less than 5 cm. Every patient was treated in a functional weight-bearing orthosis (VACOped®) for 8 weeks with early weight-bearing following a specific treatment protocol, followed by rehabilitation with a trained physiotherapist. Methods. Patients were followed up with foot and ankle trained physiotherapist for at least 1 year post-injury. At final follow up, the followings were measured: calf girth, single-leg heel raise height and repetitions. Furthermore, ATRS score and a patient feedback were taken on this final visit. Result. The mean ATRS score was 82.1, with a re-rupture rate of only 2% as compared to 5% in normal orthosis. The average calf bulk difference was 1.6 cm, the average heel raise height difference was 1.8cm and a heel raise repetition difference of 6. There was a statistically significant correlation between ATRS score and calf muscle girth (p=0.02). However, there was no significant correlation between ATRS and heel raise height or heel raise repetitions. Conclusion. Early weight-bearing in a functional orthosis provides excellent functional outcomes for conservatively managed, complete AT ruptures, and is associated with very low re-rupture rates. A multidisciplinary approach with a guided rehabilitation programme is essential for optimising functional outcome

Aim. This study was conducted to investigate the clinical outcome, functional outcome, and quality of life of patients treated for post traumatic osteomyelitis (PTO) of femur and tibia from July 2007 to June 2014. Method. Forty seven patients consented and participated in this study. The median age of participants was 44 years old, and ranges from 16 to 80 years old. There were 26 tibia and 21 femur osteomyelitis evaluated in this study. Thirty-eight participants (80.9%) had implants inserted. The PTO patients were classified according to Cierny-Mader (CM) classification: 2 CM-I; 8 CM-II; 18 CM III; 19 CM IV and 25 CM-A and 19 CM-B. The participants were follow up for a mean duration of 4.6 years (range 2.3–9.5 years). Interviews were then conducted and clinical assessments were performed to evaluate the clinical outcome. Their functional outcome was evaluated using the Lower Extremity Functional Score (LEFS) and the quality of life was evaluated using the validated SF-36v2 and the results were compared to the general population (GP). Results. Forty four (93.6%) of participants had achieved union without recurrence of infection. Others who had failure of treatment were CM-IIIA, CM-IVA, and CM-IVB. Concurrent medical problem and CM-B (Systemic) hosts significantly contributed to poorer functional outcome, and lower quality of life score especially the Physical Component domain. Conclusions. Most patients with post traumatic osteomyelitis had successful treatment. However their quality of life was poorer in comparison to the general population. Concurrent medical problem and CM-B (Systemic) hosts had significantly poorer functional outcome and quality of life than the general population

Radiographic follow-up of traumatic spondylolisthesis of the axis is well documented in the literature. However, there is a paucity of studies regarding the long-term functional outcome of this type of injury. To study the population, treatment and outcome following traumatic spondylolisthesis of the axis, we reviewed 36 consecutive patients presenting to our institution, a tertiary referral spinal trauma centre, over a 6-year period. We assessed: (a) the mechanism of injury, (b) the mode of treatment, (c) the radiographic classification using the Levine and Edwards system and (d) functional outcome using the Cervical Spine Outcomes Questionnaire (CSOQ) by BenDebba. Of the 36 patients presenting there were 24 males and 12 females with a mean age of 46 (range18-82) years. The commonest mechanism of injury was road traffic accidents. There were 14 Type-I, 11 Type-II and 1 Type-IIA fractures. Twenty-seven patients were treated with halo vest immobilisation and nine were immobilised in a Minerva jacket. Four patients were converted from halo to Minerva because of pin failure. The mean duration of hospital stay was 10 (range 3-30) days. All fractures demonstrated radiographic union at a mean of 12 (range 10-16) weeks. There were no neurological complications. Upon review, all patients, whether Type-I or Type-II demonstrated low CSOQ scores approaching their pre-morbid status. However, Type-II fractures scored higher in 3 functional outcome categories when compared to Type-I fractures. This unique study of an uncommon fracture shows for the first time a difference in the functional outcome scores of Type-II fractures of the axis when compared to Type-I fractures at a mean follow-up of 3 years and 10 months

Introduction. Aim was to compare the functional outcome of anterior cervical decompression and fusion (ACDF) with stand-alone tricotical iliac crest auto graft verses stand-alone PEEK cage. Material and methods. Prospectively collected data of 60 patients in each group was compared. Results. There was statistically significant improvement noted in postoperative Modified Japanese Orthopaedic Association scores at one year follow up for both the groups. Perioperative complications were significantly higher in the autograft group when compared with the PEEK cage group. Among the 94 patients who underwent single level non-instrumented ACDF only 4 (4.25%) had psuedoarthrosis. The fusion rate for single level ACDF in our series was 95.74%. Among the 25 patients operated for two level non-instrumented ACDF, 6 patients (24.00%) had pseudoarthrosis. The fusion rate for two levels ACDF in our series is 76.00%. There was no significant difference in fusion rates of the PEEK cage when compared to auto graft group. Conclusion. Fusion rates in ACDF are independent of interbody graft material. Fusion rates for single level ACDF is significantly higher than two levels ACDF. ACDF with PEEK is the fusion technique of choice with fewer complications and better functional recovery

Introduction. Blunt trauma of the lower limb can lead to vascular injury causing devastating outcomes, including loss of limb and even loss of life. The primary aim of this study was to determine the limb salvage rate of patients sustaining such injuries when treated at Leeds General Infirmary (LGI) since becoming a Major Trauma Centre (MTC). Secondary aims included establishing the patient complications and outcomes. Materials and Methods. Retrospective analysis found that from 2013–18, 30 patients, comprising of 32 injured limbs, were treated for blunt trauma to the lower limb associated with vascular injury. Long-term functional outcomes were determined using postal and telephone questionnaires. Results. Twenty-four patients were male and 6 were female, their mean ages were 32 and 49 respectively. Of the 32 limbs, 27 (84%) were salvaged. Three limbs were deemed unsalvageable and underwent primary amputation; of the remaining 29 potentially salvageable limbs, 27 (93%) were saved. Eleven limbs had prophylactic fasciotomies, 3 limbs developed compartment syndrome – all successfully treated, and three contracted deep infections – one of which necessitated amputation. All but 1 patient survived their injuries and were discharged from hospital. Of the 15 questionnaire responses, self-reported limb function was understandably worse post-injury with patients experiencing mild pain on average. In addition, there was a long-standing psychological impact and the injuries altered many patients’ normal lives significantly, 10 experiencing financial difficulties and 6 having changed or lost jobs post-injury. Conclusions. Fortunately, 27 (84%) limbs were salvaged and nearly all patients survived these injuries when treated at an MTC. Whilst the number of complications was low, the future challenges these patients face are wide-ranging and significant

To analyse and compare long-term functional outcome of combined spino-pelvic injuries to an isolated pelvis and spinal fractures, the outcome of matched 30 patients with combined pelvic and spinal fractures was compared with 32 patients with isolated pelvic fractures and 30 patients with isolated spinal fractures. Functional outcome was measured using the self-report questionnaire EuroQol EQ-5D, a generic outcome tool. The functional outcome was compared with the average UK population scores. The mean age, median ISS and demographic profile were similar in all 3 groups. Neurological injuries were seen in 10 patients in the combined injury group, 5 patients in the pelvic injury group and 3 patients in the spinal fracture group. 1 patient had sexual dysfunction in the combined injury group. The EuroQol EQ-5D descriptive scores for the combined group were 0.67±0.11 (0.71±0.12 for spine fracture, 0.61±0.18 for pelvic fracture) and Valuation scores for the combined injury were 69.6±11.4 (65.1±19.4 for spine fracture, 61.5±21.9 for pelvic fracture), which are p=0.004 and p=0.003 for the combined injury compared to the average UK population. Duration of hospital stay was a mean of 13 days in spine injury group compared to 49 days in the combined injury group. 70% of patients with spinal injuries returned to the same level of employment in a mean duration of 5.3 months with only 10% retired due to injury; compared to 56.6% returned to work in the combined injury group after a mean duration of 12.8 months with 23.3% retired due to injury. Long-term functional outcome is significantly better with isolated spinal injuries compared to pelvic injury or combined injury. There is no significant long-term difference between the combined spino-pelvic group and the isolated pelvic injury group. We feel that the spinal injuries in a patient with coexisting pelvic fracture do not contribute towards the overall functional outcome in those patients

Background. Adhesive capsulitis (frozen shoulder) is a debilitating condition affecting 2–5% of the adult population. Its aetiology is still unclear and there is no consensus on the most effective treatment. The aim of this retrospective study was to investigate the mid-term functional outcome of one specific treatment protocol. Methods. Patients with a diagnosis of idiopathic adhesive capsulitis treated by one orthopaedic surgeon between 2004 and 2008 were identified from outpatient clinic letters. All patients had initially received conservative treatment, consisting of physiotherapy with capsular stretches and subacromial injections. Patients in whom conservative treatment failed underwent an arthroscopic capsular release. At a minimum of two years following diagnosis patients were sent the Oxford Shoulder Score (OSS [0 to 48]), Western Ontario Rotator Cuff Index (WORC [0 to 2100]) and a satisfaction questionnaire by post. In addition case notes were reviewed and type of treatment and range of movement (ROM) recorded. Results. 60 patients with the diagnosis of idiopathic adhesive capsulitis were identified. 42 patients (70%) returned the completed questionnaires. Range of movement data was available from 43 patients (72%). Mean OSS was 41 (SD 10.7) and mean WORC 307 (SD 437.1). Analysis showed that patients in whom conservative treatment was successful had significantly better functional outcome scores in OSS and WORC and better ROM than patients who underwent surgery. Overall 33 patients (79%) were satisfied or very satisfied with the outcome of their treatment. Conclusion. This study shows that patients who respond to conservative treatment have a better functional outcome than patients who undergo surgery following failed conservative treatment. Further studies are needed to directly compare the two types of treatment

Aim. To assess the influence of route of antibiotic administration on patient-reported outcome measures (PROMS) of individuals treated for hip and knee infections in the OVIVA multi-centre randomised controlled trial. Method. This study was designed to determine whether oral antibiotic therapy is non-inferior to intravenous (IV) therapy when given for the first six weeks of treatment for bone and joint infections. Of the 1054 participants recruited from 26 centres, 462 were treated for periprosthetic or native joint infections of the hip or knee. There were 243 participants in the IV antibiotic cohort and 219 in the oral cohort. Functional outcome was determined at baseline through to one year using the Oxford Hip/Knee Score (OHS/OKS) as joint-specific measures (0 the worse and 48 the best). An adjusted quantile regression model was used to compare functional outcome scores. Results. Of the 214 participants in the hip sub-group, 110 were randomized to IV antibiotics and 104 to oral. Of the 248 participants in the knee cohort, 133 were treated with IV antibiotics and 115 with oral. The OHS/OKS questionnaire response rate was 68%. Baseline median OHS of the hip sub-group was 14 (Interquartile range [IQR]:8–22) for the IV cohort and 12 (IQR:7–22) for the oral cohort. The one-year median OHS was 35 (IQR: 23–44) for the IV cohort and 27 (IQR:16–40) for the oral cohort with no significant difference between cohorts (p=0.181). The baseline median OKS of the knee sub-group, was 14 (IQR:8–23) for the IV cohort and 12 (IQR:8–21) for the oral cohort. The one-year median OKS was 24 (IQR: 15–35) for the IV cohort and 27 (IQR:17–38) for the oral cohort with a statistically significant difference in favour of oral therapy (p=0.036). Conclusions. At one year, there was improvement in functional outcome of patients treated with either IV or oral antibiotics in this RCT. It suggests that joint function generally improved progressively following the start of treatment irrespective of the route of antibiotic therapy. Functional outcome of patients with hip infections was similar irrespective of the route of antibiotic therapy, whereas there was statistically greater improvement in functional outcome of patients with knee infections treated with oral antibiotics. The PROMS findings of this trial support the clinical findings (i.e. infection eradication rates) and suggest that there is no advantage of using prolonged intravenous therapy as compared to oral therapy in the early treatment of infections around the hip and knee joint

Introduction. Fracture around the knee can lead to posttraumatic osteoarthritis (PTOA) of the knee. Malunion, malalignment, intra-articular osseous defects, retained internal fixation devices, and compromised soft tissues may affect the outcome of total knee replacement (TKR). On average, the posttraumatic patient subsets were 10.4 years younger than those for primary knee OA. Recently, there were several studies reporting the outcome of THA for posttraumatic OA hip. However, no current literature defines the comparative functional outcome between PTOA and primary OA knee. The purpose of our study was to compare the midterm outcomes of patients undergoing TKR following periarticular knee fractures/ligamentous injuries versus primary osteoarthritis (PO) of the knee. Materials and methods. Retrospective chart reviews of patients underwent TKR between 2008 and 2013 were identified. 136 patients underwent open reduction and internal fixation with plate and screws or ligament reconstruction while 716 patients were primary OA. Mean follow up time was comparable in both groups. Demographic data, medical comorbidities, WOMAC, visual analogue scale, and complications were recorded. Results. There were significantly different in age (56.5 vs 63.8 years, p<0.0001), gender (48.5% vs 63.1% of female, p=0.0014), and obese (62.3% vs 76.0%, p=0.025) between PTOA and PO groups, respectively. The PO group had higher comorbidities than PTOA group including anticoagulant usage (51% vs 30.9%, p=0.0002), number of disease ≥ 4 (69.6% vs 45.3%, p<0.0001), ASA class ≥3 (38.8% vs 21.6%, p<0.0001), and Charlson Comorbidity Index (3.6 vs 2.8, p<0.0001). The PTOA group had longer operative time (110.9 vs 100.1 minutes, p<0.0001) than PO group. Preoperatively anatomical axis of the knee was approximately valgus in PTOA but varus alignment in PO group (p<0.0001). However, postoperatively anatomical and mechanical axis was comparable in both groups. Postoperative VAS (1.8 vs 1.2, p=0.002) at 1 year follow up and pain component of WOMAC (77.8 vs 85.7, p=0.013) in PTOA group was worse than PO group, respectively. On the contrary, there was no difference in postoperative complication and readmission rate between groups. Conclusion. Total knee replacement for Post-traumatic OA was associated with poorer functional outcome compared to those for primary osteoarthritis in midterm follow up

Aim. Data of optimal management of infections after internal fixation (IIF) is scarce and long-term follow-up results often lack. We analyzed characteristics of infections after intramedullary (IIIF) and extramedullary long bone fixation (IEIF) and evaluated their infection and functional outcome. Method. Consecutive patients with IIF diagnosed at our institution from 01/2010-10/2017 were retrospectively included. Infection was defined as visible purulence, sinus tract, microbial growth in ≥2 independent samples or positive histopathology. The outcome was compared before and after implementation of a comprehensive surgical and antimicrobial treatment algorithm in 04/2013. Results. Of 127 patients, infection involved lower extremity in 111 patients (87%). Median age was 53 years (range, 19–89 years), 70% were men. Fixation was performed with intramedullary nail in 47 (37%) and with extramedullary osteosynthesis (plates, screws, pins) in 80 patients (63%). At infection diagnosis, the implant was in situ in 96 patients (76%), whereas 31 patients (24%) had residual osteomyelitis after implant removal. The time from bone fixation to infection was longer in IIIF than IEIF (25 vs. 7 months, p=0.027). Pain was reported in 55 patients (43%) and local infection signs in 96 patients (75%), including sinus tract in 46 patients, more commonly reported after IIIF than IEIF (49% vs. 29%, p=0.035). Infections were monomicrobial in 85 (67%), polymicrobial in 18 (14%) and culture-negative in 23 patients (18%). Most common pathogens were S. aureus (43%), coagulase-negative staphylococci (28%) and gram-negative rods (22%). Débridement (with device retention, if present) was performed in 40, device removal in 43, one-stage exchange in 16 and two-stage exchange in 20 patients. One patient had no surgery and 7 patients underwent limb amputation. 43 patients (34%) were treated before implementation of the interdisciplinary treatment concept and 84 patients (66%) afterwards. Among 111 patients with available follow-up (median, 5.2 months; range, 0.2–86 months), in 78 cases (70%) infection eradication was achieved (similar in IIIF and IEIF). However, overall infection and functional outcome was only 48% (53 patients). After implementation of the treatment algorithm, the infection outcome improved from 56% to 79% (p=0.03) and the overall success from 33% to 56% (p=0.016). Conclusions. Approximately half of infections after IIF failed in terms of infection eradication or restoration of function. After implementation of standardized surgical and antibiotic treatment concept, infection and functional outcome improved significantly. No significant differences between IIIF and IEIF was observed in terms of infection and functional success

Purpose. Limited information is available regarding the functional outcomes of radial head fractures managed with open reduction and internal fixation (ORIF). The purpose of this study was to determine the functional outcomes of radial head fractures treated with ORIF. Method. Fifty-two patients, with a mean age of 4412 years, who were treated with radial head ORIF were evaluated at a mean of 4.42.4 years. Thirty were isolated radial head fractures (Group A), 13 (Group B) were associated with a complex fracture-dislocation (terrible triad variants), and 5 (Group C) were associated with a proximal ulnar fracture (Monteggia/trans-olecranon variants). Fourty-four were partial articular fractures and 8 were complete articular fractures. Outcomes were assessed with physical and radiographic examination, and validated self-reported questionnaires. Results. The average PREE score (Patient Rated Elbow Evaluation) for Groups A, B, and C were 7.613.1, 12.313.4, and 108.5, respectively. The average MEPI (Mayo Elbow Performance Score) for Groups A, B, and C were 8913, 8511, and 918, respectively. For Groups A, B, and C respectively, the prevalence of radiographic radiocapitellar arthritis was 30%, 46%, and 20%. The average flexion/extension arc for Groups A, B, and C were 7 to 132, 6 to 134, and 10 to 132 respectively. Secondary surgery was performed in 17% of cases, most commonly for decreased motion. Three comminuted fractures failed ORIF and required conversion to radial head arthroplasty. Conclusion. Patients with radial head fractures, including those associated with complex fracture-dislocations, can achieve excellent functional outcomes with low self reported pain and disability when treated with ORIF, despite radiographic evidence of mild post-traumatic arthritis

Introduction. Bilateral total knee replacement can either be simultaneous, in which both knees are operated in the same sitting, in one day, or staged, in which both knees are operated but not on the same day. With appropriate patient selection, the potential benefits of conducting this procedure in a simultaneous fashion outweigh the possible risks of the procedure. Very few studies have evaluated the results of bilateral knee replacement in a single sitting in Indian population. Objectives. To determine the functional outcome after simultaneous knee replacement and assessment of the peri and post operative complications. Methods. Patients undergoing bilateral total knee arthroplasty in a single sitting by a single surgeon using standard technique and posterior stabilized cruciate substituting prosthesis. Evaluation was done using Hospital for Special Surgery Knee and Function scores. Results. The mean knee score improved to 85.81 from 67.83 and the mean function score improved to 83.15 from 69.14. Post operative complications included two cases of acute coronary syndrome, one case of psychosis and another of opiod withdrawal. Conclusions. Simultaneous bilateral total knee replacement remains an appropriate option in select patients

Introduction. Growing evidence in the literature suggests better clinical and functional outcomes and lower re-rupture rates with repair compared to non-operative treatment of ruptured Achilles tendon. There are however, concerns of wound infection, nerve injury and scar tenderness with the standard open and percutaneous techniques of repair. We aim to evaluate clinical and functional outcomes and complications in patients treated with minimally invasive Achillon device. Materials and Methods. Prospectively collected clinical data was reviewed of all consecutive patients who underwent repair of the ruptured Achilles tendon using the Achillon device. Patients were contacted using a postal questionnaire for assessment of their functional status using the validated Achilles Tendon Total Rupture Score (ATRS) and compared with their uninjured side. The outcomes were compared to the published results. Results. We present patient demographics; and clinical and functional outcomes of 140 consecutive patients who underwent repair of ruptured Achilles tendon using the minimally invasive technique between June 2007 to August 2010. Our complication rate was of two-three percent each of proximal DVT, scar sensitivity, superficial wound infection and no re-rupture after a minimum of 6 months. There was no case of nerve injury leading to permanent neurological deficit. Discussion. This study demonstrates good clinical and functional outcomes from using the Achillon device in repair of ruptured Achilles tendon with a low complication rate comparable to other published series. We recommend Achillon device as a safe minimally invasive technique for repair of the ruptured Achilles tendon

Management of pseudotumours associated with MoM THA can be difficult and complications are frequent. The functional outcome of patients after revision surgery may be suboptimal. The objective of this study was to assess our experience with revisions of failed MoM THA due to pseudotumours. 78 hips were diagnosed with pseudotumours in 70 patients following metal-on-metal hip replacements. Of these, 68 MoM THA were revised in 62 patients. Pre operative symptoms, radiographic analysis, metal ion levels, MRI results, intra-operative findings, WOMAC scores, the satisfaction level and the complication rate were recorded. Five patients had a resurfacing arthroplasty as their primary implants while the remaining 63 hips in 57 patients had MoM THA of different brands. The average time between the primary and revision surgery was 69 months (range 15–120). The average age at revision was 59 years (43–87). The mean follow-up was 24 months (range 2–73). 36 patients had minimal one year follow-up. Most lesions consisted of cystic changes and solid lesions were observed in 19 patients. In 57 hips, the pseudotumours were located posteriorly or postero-laterally around the greater trochanter. Intra operatively, muscle necrosis was observed in 15(22%) patients. Most THA cases demonstrated wear and corrosion at the head neck junction of the femoral implants. Thirty-five patients (44.9%) had greater than 50 degrees of cup abduction, including 10 patients (12.8%) with an abduction angle greater than 60 degrees. The average pre operative and postoperative Co ion levels were 27.46 ug/L (range 0.36–145.6) and 2.46 (range 0.4–12.48), respectively. Post revision, a total of 10 hips (14.7%) sustained a dislocation, with seven (10.3%) of them experiencing recurrent dislocations. In 8/10 hips, the femoral head size was 36mm or greater. Revision for dislocation occurred in seven(10.3%) patients. Three(4.4%) deep and one(1.47%) superficial infections occurred and deep infections were re-operated. One(1.47%) fracture of the greater trochanter and one (1.47%) psoas tendinitis did not need revision. Therefore, a total of 10 patients (14.7%) were reoperated. 6 revisions for instability were performed in the first 34 patients, while 1 were done in the last 34 patients. At one year post revision surgery, the mean WOMAC score was 19.68 (range 0–48). In comparison, the mean WOMAC score of the same patients one year after their primary surgery was 8.1 (0–63). Patient satisfaction level of patients one year post revision surgery was 7.61 (range 5–10) compared to 4.15 (range 0–7) pre-revision one. The complication rate after revision of pseudotumours is high. Most re revisions occurred secondary to instability despite the use of larger femoral heads. The functional outcome at one year post revision seems to be lower than that seen after primary THA but similar to other revisions in the literature. Experience in the management of these patients may reduce the complication rate

Purpose. Although classic teaching holds that the least amount of constraint should be implanted, there is very little in the literature to substantiate this. This study attempts to quantify the influence of constraint and various indications upon functional outcome following aseptic first time revision knee arthroplasty. The null hypothesis was that the level of constraint and indication for surgery would not influence the functional outcome following revision knee replacement. Methods. A single centre prospective study was performed to examine the outcome for 175 consecutive total revision knee replacements performed between 2003 and 2008 with a minimum follow-up of two years. Patient reported outcome data was used to determine the influence of final level of component constraint and its relationship with primary indication for surgery. Results. All patients were found to have a significant improvement for WOMAC pain, function and stiffness score (p< 0.001) and physical functioning, role physical, bodily pain and social functioning components of SF-36 score (p< 0.05). 69% were satisfied with the overall procedure. WOMAC function, pain and stiffness score was significantly worse for patients revised for instability (27%) compared to that for aseptic loosening (46%). A significantly higher proportion of patients were satisfied with the procedure (p< 0.001), had a better quality of life (p=0.004) and would have the surgery (p=0.005) again in the aseptic loosening group as compared to the instability group. Revision to a higher level of constraint did not improve knee function irrespective of the primary indication for surgery. Conclusion. Revision for an instability pattern irrespective of choice of new device was met with significantly poorer functional outcome

Aim. Advocates of Debridement-Antibiotics-and-Implant-Retention (DAIR) in hip peri-prosthetic joint infection (PJI) argue that a procedure not disturbing a sound prosthesis-bone interface is likely to lead to better survival and functional outcome compared to revision. However, no evidence supports this. This case-control study's aims were to compare outcome of DAIRs for infected 1° total hip arthroplasty (THA) with outcomes following 1° THA and 2-stage revisions of infected 1° THAs. Method. We retrospectively reviewed all DAIRs, performed for confirmed infected 1° THR (DAIR-Group, n=80), in our unit between 1997–2013. Data recorded included patient demographics, medical history, type of surgery and organism identified. Outcome measures included complications, mortality, implant survivorship and functional outcome using the Oxford Hip Score (OHS). Outcome was compared with 2 control groups matched for gender and age; a cohort of 1° THA (1°-THA-Group, n=120) and a cohort of 2-stage revisions for infection (2-Stage-Revision-Group, n=66). Results. The mean age at DAIR was 69 years and mean follow-up was 8 years (SD:5). 60% of DAIRs were for early PJI (< six weeks). Greater infection eradication with DAIR was detected with early-PJI, interval less than a week between onset of symptoms and exchange of modular components with the DAIR procedure. Infection eradication, complications and re-operation rates were similar in the DAIR- and 2-stage-revision Groups (p>0.05). For hips with successful infection eradication with DAIR, the 5-yr survival (98%) was similar to the 1°THA-Group (98%) (p=0.3). The DAIR-Group had inferior OHS (38) compared to the 1°THA-Group (42) (p=0.02) but significantly better OHS compared to the 2-stage-revision-Group (31) (p=0.008). Patients that required only one DAIR for infection eradication had similar OHS (41) to the 1° THA-Group (p=0.2). Conclusions. DAIRs are associated with similar complication and infection eradication to 2-stage revisions. Exchange of modular components is advised for improved chances of infection eradication. Functional outcome following DAIRs was better than a 2-stage revision and as good as that of a 1° THA if a single DAIR was necessary for infection eradication

Background:. Modified posterior approach and its effect on stability and functional outcome in total hip arthroplasty. Material & Methods:. A retrospective comparative evaluation was done to assess the functional outcome and rate of dislocation in 233 hips (Group A) operated before 2007 by convention posterior approach and 567 hips (Group B) were operated by modified posterior approach.(2007–2011) In this modified posterior approach technique, 2–3 stay sutures (non-absorbale Nylon) are applied in the piriformis tendon, short external rotator and proximal part of Quadratous muscle. Then a conjoint- myocapsular sleeve is raised by starting cutting (with cautery) linearly over the capsule with adherent fibers of gluteus minimus to piriformis tendon, short rotators and part of quadratus to expose and dislocate the head. After inserting the definite prosthesis, upper part of sleeve (capsule, piriformis tendon) is sutured with same nonabsorbable Nylon at the lower part of tip of greater trochanter by passing through the bone with needle or by drilling the bone; lower part of the sleeve is tied with lateral trochanteric bone. Additional stability to repair was given by closing the tendinous part of the gluteus maximus by horizontal cross mattress sutures up its attachment to the proximal femoral shaft. Results:. All patients underwent cementless total hip arthroplasty; average Harris hip score at minimum 3.1 yr follow was 88.7 in Group B & 85.2 in Group B. Group B had only one dislocation while Group A had 12 dislocations (5%). Conclusion:. This technique provide enhanced stability and improve functional outcome
