Open debridement and Outerbridge and Kashiwagi debridement arthroplasty (OK procedure) are common surgical treatments for elbow arthritis. However, the literature contains little information on the long-term survivorship of these procedures. The purpose of this study was to determine the survivorship after elbow debridement techniques until conversion to total elbow arthroplasty and revision surgery. We performed a retrospective chart review of patients who underwent open elbow surgical debridement (open debridement, OK procedure) between 2000 and 2015. Patients were diagnosed with primary elbow osteoarthritis, post-traumatic arthritis, or inflammatory arthritis. A total of 320 patients had primary surgery including open debridement (n=142) and OK procedure (n=178), and of these 33 patients required a secondary revision surgery (open debridement, n=14 and OK procedure, n=19). The average follow-up time was 11.5 years (5.5 - 21.5 years). Survivorship was analyzed with Kaplan-Meier curves and Log Rank test. A Cox proportional hazards model was used assess the likelihood of conversion to total elbow arthroplasty or revision surgery while adjusting for covariates (age, gender, diagnosis). Significance was set p<0.05. Kaplan-Meier survival curves showed open debridement was 100.00% at 1 year, 99.25% at 5 years, and 98.49% at 10 years and for OK procedure 100.00% at 1 year, 98.80% at 5 years, 97.97% at 10 years (p=0.87) for conversion to total elbow arthroplasty. There was no difference in survivorship between procedures after adjusting for significant covariates with the cox proportional hazard model. The rate of revision for open debridement and OK procedure was similar at 11.31% rand 11.48% after 10 years respectively. There were higher rates of revision surgery in patients with open debridement (hazard ratio, 4.84 CI 1.29 – 18.17, p = 0.019) compared to OK procedure after adjusting for covariates. We also performed a stratified analysis with radiographic severity as an effect modifier and showed grade 3 arthritis did better with the OK procedure compared to open debridement for survivorship until revision surgery (p=0.05). However, this difference was not found for grade 1 or grade 2 arthritis. This may suggest that performing the OK procedure for more severe grade 3 arthritis could decrease reoperation rates. Further investigations are needed to better understand the indications for each surgical technique. This study is the largest cohort of open debridement and OK procedure with long term follow-up. We showed that open elbow debridement and the OK procedure have excellent survivorship until conversion to total elbow arthroplasty and are viable options in the treatment of primary elbow osteoarthritis and post traumatic cases. The OK procedure also has lower rates of revision surgery than open debridement, especially with more severe radiographic arthritis

Introduction. Open and arthroscopic hip debridement may be used for treatment of femoral acetabular impingement (FAI). There is a paucity of evidence regarding the efficacy of one over the other. Aim. To compare survivorship in terms of further surgical procedure at five years, in patients having undergone either arthroscopic or open hip debridement. Methods. Using our institutional database, we identified all post learning curve arthroscopic and open hip debridement cases with five years of follow up. Patients were matched based on age, gender and Tonnis grade. The primary outcome measure was 5 year survivorship to total hip arthroplasty (THA). Secondary outcome measures included 5 year survivorship to further (non THA) procedures on the joint. Radiological parameters were analysed including femoral neck version, sourcil, centre-edge and alpha angles. Results. A total of 390 arthroscopic and 1316 open operations were identified. Following exclusion and matching 102 (62 female, 39 male) cases were available for analysis in each group. Mean age was 36 years (range 17–51). At 5 years 14.8% of arthroscopic debridement patients and 5.9% of open debridement patients had undergone THA (p =0 .038). There was no statistical difference in secondary outcome measures. Discussion. A significantly higher percentage of patients undergoing arthroscopic debridement went on to THA when compared to matched patients receiving open debridement. We acknowledge the limitations of this study. However, despite the increasing prevalence of arthroscopic surgery to treat FAI, our results would suggest that open debridement may still remain the gold standard intervention. Further investigation, ideally in the form of an RCT, is warranted. Conclusion. In our case matched series, despite the longer rehabilitation and greater soft tissue insult, open surgery for FAI was associated with significantly less patients progressing to THA within 5 years compared to those undergoing arthroscopic debridement

To reveal if patient reported knee-related pain, function, quality of life, general health and satisfaction at one year after primary total knee arthroplasty (TKA) is different between patients not being subject to revision surgery and those having had early treatment with open debridement and exchange of the tibial insert for postoperative PJI. The Swedish Knee Arthroplasty Register was used to identify 50 patients in the region of Skane that had a primary TKA during the years 2008 – 2012 and within 6 months were revised with open debridement and exchange of the tibial insert due to suspected or verified PJI. Only patients without further revisions were included. Patient reported outcome measurements (PROM) were obtained preoperatively and 1 year postoperatively and included knee related pain, function, quality of life using the Knee injury and Osteoarthritis Outcome Score (KOOS), general health using the EQ-VAS as well as satisfaction with the surgery. The scores were compared to those reported by 3,913 patients having a TKA during the same time but not revised during the first year. Welch's t-test and the Chi2-test were used in statistical analysis. Compared to the controls the infected patients were older (mean age 72 vs 69 years, p = 0.04) and were more morbid (ASA 3; 14/50 patients vs 14%, p = 0.02). The preoperative PROM data were similar. Complete 1 year PROM data was available for 31 of the patients. Those patients reported somewhat worse outcome one year postoperatively than the controls with statistically and clinically significant differences in general health (mean 61 vs 76, p=0.002), KOOS ADL (mean 65 vs 76, p=0.03) and knee related quality of life (mean 51 vs 63, p=0.02) with large variations on individual level. Just over half of the patients (17/29) treated for PJI were very satisfied or satisfied with the surgery compared to 79% of the controls. Patients treated with open debridement and exchange of the tibial insert due to early PJI after primary TKA reported less beneficial postoperative outcome than those without revision surgery during the first postoperative year but with large individual variations

Aims. The treatment of septic arthritis of the shoulder is challenging. The infection frequently recurs and the clinical outcome can be very poor. We aimed to review the outcomes following the use of continuous negative pressure after open debridement with a large diameter drain in patients with septic arthritis of the shoulder. Patients and Methods. A total of 68 consecutive patients with septic arthritis of the shoulder underwent arthrotomy, irrigation and debridement. A small diameter suction drain was placed in the glenohumeral joint and a large diameter drain was placed in the subacromial space with continuous negative pressure of 15 cm H. 2. O. All patients received a standardised protocol of antibiotics for a mean of 5.1 weeks (two to 11.1). Results. Negative pressure was maintained for a mean of 24 days (14 to 32). A total of 67 patients (98.5%) were cured without further treatment being required. At a mean follow-up of 14 months (three to 72), the mean forward flexion was 123° (80° to 140°) and the mean external rotation was 28°(10° to 40°) in those with a rotator cuff tear, and 125° (85° to 145°) and 35° (15° to 45°) in those without a rotator cuff tear. Conclusion. Continuous negative pressure, following open arthrotomy, irrigation and debridement, was effective in treating septic arthritis of the shoulder. The rate of recurrence was significantly lower than with conventional treatment involving arthroscopic or open debridement reported in the literature. Functional outcomes, even in patients with rotator cuff tears, were excellent. Take home message: Continuous negative pressure is effective in treating septic arthritis of the shoulder.

Introduction. Open hip debridement surgery has been used for treatment of femoral acetabular impingement pain for over ten years in our unit. While literature has reported promising short-term outcomes, longer term outcomes are more sparsely reported. Patients/Materials & Methods. Patients who had undergone this surgery were identified on our database. Electronic, radiographic and paper records were reviewed. Demographic data, radiological and operative findings were recorded. Patients underwent ten-year review with standardised AP hip radiographs, questionnaire, non-arthritic hip (NAHS), Oxford hip (OHS) and SF-12 scores. Results. A total of 1626 operations were identified of which 183 had reached the tenth anniversary of their surgery. There were 91 females and 92 males. The average age was 39. Kaplan-Meier analysis indicated an overall 78% survival at ten years. However, once the learning curve was accounted for, by excluding the first year's cohort of patients, the survival rate was 84% at 10 years. Those who underwent hip arthroplasty were older at initial surgery and had a higher Tonnis grade than those who survived. The majority failed within the first 2 years. Labral repair, restoration of a normal centre edge angle and adequate CAM correction were associated with better survival. In those whose hip survived, the average NAHS and OHS were 87 and 39 respectively. 15% required further non-arthroplasty surgery (scope/revision) and 51% underwent trochanteric screw removal. 89% of survivors deemed their surgery to have been worthwhile at ten year follow up. Discussion. These results represent the first cohorts of our patients to reach ten year follow up. The results represent a learning curve in patient selection. It is unsurprising that those with more arthritic change were more likely to fail. Conclusion. In patients with clearly defined CAM impingement without joint space narrowing and where successful resection of the CAM and restoration of a normal centre edge angle can be achieved open hip debridement remains an operation with worthwhile outcomes at ten years

Background. Charcot neuroarthropathy is a destructive disease characterized by progressive bony fragmentation as a result of the isolated or accumulative trauma in patients with decreased sensation that manifests as dislocation, periarticular fractures and instability. Although amputation can be a reasonable cost economic solution, many patients are willing to avoid that if possible. We explored here one of the salvage procedures. Methods. 23 patients with infected ulcerated unstable Charcot neuroarthropathy of the ankle were treated between 2012 and 2017. The mean age was 63.5 ±7.9 years; 16 males and 7 females. Aggressive open debridement of ulcers and joint surfaces, with talectomy in some cases, were performed followed by external fixation with an Ilizarov frame. The primary outcome was a stable plantigrade infection free foot and ankle that allows weight bearing in accommodative foot wear. Results. Limb salvage was achieved in 91.3% of cases at the end of a mean follow up time of 25 months (range: 19–32). Fifteen (71.4%) solid bony unions were evident clinically and radiographically, while 6 (28.5%) patients developed stable painless pseudoarthrosis. Two patients had below knee amputations due to uncontrolled infection. Conclusion. Aggressive debridement and arthrodesis with ring external fixation can be used successfully to salvage severely infected Charcot arthropathy of the ankle. Pin tract infection, delayed wound healing and stress fracture may complicate the procedure but can be easily managed. Amputation may be the last resort in uncontrolled infection

Sternoclavicular joint infections are uncommon but severe and complex condition usually in medically complex and compromised hosts. These infections are challenging to treat with risks of infection extending into the mediastinal structures and surgical drainage is often faced with problems of multiple unplanned returns to theatre, chronic non-healing wounds that turn into sinus and the risk of significant clinical escalation and death. Percutaneous aspirations or small incision drainage often provide inadequate drainage and failed control of infection, while open drainage and washout require multidisciplinary support, due to the close proximity of the mediastinal structures and the great vessels as well as failure to heal the wounds and creation of chronic wound or sinus. We present our series of 8 cases over 6 years where we used the plan of open debridement of the Sternoclavicular joint with medial end of clavicle excision to allow adequate drainage. The surgical incision was not closed primarily, and a suction vacuum dressing was applied until the infection was contained on clinical and laboratory parameters. After the infection was deemed contained, the surgical incision was closed by local muscle flap by transferring the medial upper sternal head of the Pectoralis Major muscle to fill in the sternoclavicular joint defect. This technique provided a consistent and reliable way to overcome the infection and have the wound definitively closed that required no secondary procedures after the flap surgery and no recurrence of infections so far. We suggest that open and adequate drainage of Sternoclavicular joint staged with vacuum dressing followed by pectoralis major local flap is a reliable technique for achieving control of infection and wound closure for these challenging infections

Tendoscopy in the treatment of peroneal tendon disorders is becoming an increasingly safe, reliable, and reproducible technique. Peroneal tendoscopy can be used as both an isolated procedure and as an adjacent procedure with other surgical techniques. The aim of our study was to review all peroneal tendoscopy that was undertaken at the AOC, by the senior authors (IGW, SH), and to determine the safety and efficacy of this surgical technique. Methods. From 2000 to 2017 a manual and electronic database search was undertaken of all procedures by the senior authors. Peroneal tendoscopy cases were identified and then prospectively analysed. Results. 51 patients (23 male, 28 female) were identified from 2004–2017 using a manual and electronic database search. The mean age at time of surgery was 41.5 years (range 16–83) with a mean follow-up time post operatively of 11.8 months (range 9–64 months). The main indications for surgery were lateral and/or postero-lateral ankle pain and lateral ankle swelling. The majority of cases showed unstable peroneal tendon tears that were debrided safely using tendoscopy. Of the 51 patients, 23 required an adjacent foot and ankle operation at the same time, 5 open and 17 arthroscopic (12 ankle, 5 subtalar). Open procedures included 2 first ray osteotomies, 2 open debridements of accessory tissue, one PL to PB transfer. One patient also had an endoscopic FHL transfer. Complication rates to date have been low: 2 superficial wound infections (4%) and one repeat tendoscopy for ongoing pain. A small proportion of patients with ongoing pain were treated with USS guided steroid injections with good results. Conclusion. Our series of peroneal tendoscopy has a low complication rate with high patient satisfaction at discharge. Results of tendoscopic treatment are similar to open techniques, however its advantages make tendoscopic procedures an excellent method to treat peroneal tendon disorders

Aims. Our purpose was to describe an unusual series of 21 patients with fungal osteomyelitis after an anterior cruciate ligament reconstruction (ACL-R). Methods. We present a case-series of consecutive patients treated at our institution due to a severe fungal osteomyelitis after an arthroscopic ACL-R from November 2005 to March 2015. Patients were referred to our institution from different areas of our country. We evaluated the amount of bone resection required, type of final reconstructive procedure performed, and Musculoskeletal Tumor Society (MSTS) functional score. Results. A total of 21 consecutive patients were included in the study; 19 were male with median age of 28 years (IQR 25 to 32). All ACL-R were performed with hamstrings autografts with different fixation techniques. An oncological-type debridement was needed to control persistent infection symptoms. There were no recurrences of fungal infection after median of four surgical debridements (IQR 3 to 6). Five patients underwent an extensive curettage due to the presence of large cavitary lesions and were reconstructed with hemicylindrical intercalary allografts (HIAs), preserving the epiphysis. An open surgical debridement was performed resecting the affected epiphysis in 15 patients, with a median bone loss of 11 cm (IQR 11.5 to 15.6). From these 15 cases, eight patients were reconstructed with allograft prosthesis composites (APC); six with tumour-type prosthesis (TTP) and one required a femoral TTP in combination with a tibial APC. One underwent an above-the-knee amputation. The median MSTS functional score was 20 points at a median of seven years (IQR 5 to 9) of follow-up. Conclusion. This study suggests that mucormycosis infection after an ACL-R is a serious complication. Diagnosis is usually delayed until major bone destructive lesions are present. This may originate additional massive reconstructive surgeries with severe functional limitations for the patients. Level of evidence: IV. Cite this article: Bone Joint Open 2020;2(1):3–8

Periprosthetic joint infection (PJI) is a major complication affecting >1% of all total knee arthroplasties, with compromise in patient function and high rates of morbidity and mortality. There are also major socioeconomic implications. Diagnosis is based on a combination of clinical features, laboratory tests (including serum and articular samples) and diagnostic imaging. Once confirmed, prompt management is required to prevent propagation of the infection and further local damage. Non-operative measures include patient resuscitation, systemic antibiotics, and wound management, but operative intervention is usually required. Definitive surgical management requires open irrigation and debridement of the operative site, with or without exchange arthroplasty in either a single or two-stage approach. In all options, the patient's fitness, comorbidities and willingness for further surgery should be considered, and full intended benefits and complications openly discussed. Late infection almost invariably leads to implant removal but early infections and acute haematogenous infections can be managed with implant retention – the challenge is to retain the original implant, having eradicated infection and restored full function. Debridement with component retention: Open debridement is indicated for acute postoperative infections or acute haematogenous infections with previously well-functioning joints. To proceed with this management option the following criteria must be met: short duration of symptoms - ideally less than 2–3 weeks but up to 6; well-fixed and well-positioned prostheses; healthy surrounding soft tissues. Open debridement is therefore not an appropriate course of management if symptoms have been prolonged – greater than 6 weeks, if there is a poor soft tissue envelope and scarring, or if a revision arthroplasty would be more appropriate due to loosening or malposition of the implant. It is well documented in the literature that there is an inverse relationship between the duration of symptoms and the success of a debridement. It is thought that as the duration of symptoms increases, other factors such as patient comorbidities, soft tissue status and organism virulence play an increasingly important role in determining the outcome. There is a caveat. Based on our learning in the hip, when we see an acute infection where periprosthetic implants are used, it is much easier to use this time-limited opportunity to remove the implants and the associated biofilm and do a single-stage revision instead of just doing a debridement and a change of insert. This will clearly be experience and prosthesis-dependent but if the cementless implant is easy to remove, then it should be explanted. One critical aspect of this procedure is to use one set of instruments and drapes for the debridement and to then implant the new mobile parts and close using fresh drapes and clean instruments. Units that have gained expertise in single-stage revision will find this easier to do. After a debridement, irrigation, and change of insert, patients continue on intravenous antibiotics until appropriate cultures are available. Our multidisciplinary team and infectious disease experts then take over and will dictate antibiotic therapy thereafter. This is typically continued for a minimum of three months. Patients are monitored clinically, serologically, and particularly in relation to nutritional markers and general wellbeing. Antibiotics are stopped when the patients reach a stable level and are well in themselves. All patients are advised to re-present if they have an increase in pain or they feel unwell

Infection is a potentially disastrous complication of total knee arthroplasty (TKA). Although advances in surgical technique and antibiotic prophylaxis have reduced the incidence of infection to approximately 1% in primary TKA, there is still a substantial number of patients. Treatment options include antibiotic suppression, irrigation and debridement with component retention (with or without polyethylene exchange), one-stage or two-stage revision, resection arthroplasty and rarely arthrodesis or amputation. Salvage of prostheses has always been associated with low rates of success. It was reported a success rate of 27% for open debridement. It is suitable for selective cases where infection occurs within the first 4–6 weeks of primary TKA or in the setting of acute hematogenous gram positive infection with stable implants. With the advances in arthroscopic technique, arthroscopy after TKA has become an accepted method to assess and manage the complications of TKA. Arthroscopic treatment for infected TKA was reported and the successful rate was similar or better than open debridement in selected situations. We used arthroscopic debridement combined with continuous antibiotic irrigation and suction to treat acute presentation of infected TKA with acceptable result. From 2010∼2013, we has performed arthroscopic debridement and continuous antibiotic irrigation system for seven patients with infected TKA. All of the seven patients had no open wounds nor sinuses and no radiological evidence of prosthetic instability or evidence of osteomyelitis. Most of the surgical intervention was performed within two weeks from the onset of symptoms. Arthroscopic debridement was performed with a shaver using a multiportal technique (anterolateral, anteromedial, superolateral, superomedial, posterolateral, posteromedial) and a continuous antibiotic irrigation system was used to dilutes concentration of the causative microorganism and keep high local bactericidal concentration of antibiotics. We evaluated the efficacy by using follow up of the C-reactve protein (CRP) test, erythrocyte sedimentation rate (ESR) test and physical examination. Successful treatment was defined as prosthesis retention without recurrent infection by the final follow-up. Six of seven infected TKA were cured without recurrence at a mean follow-up of 23 months (range, 6–41 months). One case with rheumatoid arthritis under long-term steroid therapy had recurred after episode of upper respiratory tract infection for 3 times. However, the infection was controlled by arthroscopic debridement and retention of the prosthesis was achieved. We emphasize the importance of posterior portal to ensure adequate arthroscopic debridement. It is imperative to make early diagnosis and treatment for infected TKA. We should make more effort to preserve the prosthesis in acute infection(within 2 weeks). With the advantage of minimal morbidity, arthroscopic treatement shoulder be an alternative to open debridement

Background. Septic knee arthritis is one of the most serious complications after total knee arthroplasty (TKA), and the effectiveness of its treatment affects the patient's quality of life. In our super-aging society, the frequency of TKA in the elderly, often combined with various comorbidities, is increasing. Careful management should be considerd during the management of septic arthritis after TKA in these patients. Purpose. To analyze the clinical features and outcomes of septic arthritis after TKA in our institution. Materials and Methods. Between April 1999 and March 2014, 534 TKAs (osteoarthritis [OA]; 381, rheumatoid arthritis [RA]; 154) were performed. Of these patients, 8 with post-operative infected TKA were retrospectively surveyed. Results. The TKA-associated infection rates were 0.83% (0.35%, OA; 1.7%, RA) during the study period. Five male and 3 female patients were included, with a mean age of 68 years (range, 39–88 years) and primary diagnoses of OA (5) and RA (3). Malignant rheumatoid arthritis (MRA) was present in 1 patient. The infection was affected by a comorbidity in 2 (diabetes mellitus and mixed connective tissue disease). Microorganisms were detectable in 7 patients (methicillin-resistant Staphylococcus aureus [MRSA], 1; methicillin-sensitive Staphylococcus aureus, 2; Streptococcus pyogens, 1; Streptococcus oralis, 1; Escherichia coli, 1; Staphylococcus epidermidis, 1; and unknown, 1) (Fig. 1). The use of the Segawa/Leone classification resulted in 5 patients with type III (acute hematogenous) and 3 with type IV (late) infections. Four patients with type III (80%) infection underwent open debridement, continuous irrigation, and successful implant retention (Fig. 2). The MRA patient had type III infection and an MRSA infection that was treated with two-stage revision, but the infection recurred. We could not perform a re-implantation, and resection arthroplasty was needed. Arthroscopic irrigation in 1 patient with type III infection ended in failure, and open debridement was required. We attempted to retain the implant in 1 patient with type IV infection, but implant removal was required. Three patients with type IV infection underwent two-stage revision successfully. Discussion. The post-TKA infection rate was 0.83% in our institution. Of the implants, 50% (type III, 80%; type IV, 0%) were successfully retained. Early open debridement and irrigation are important for implant retention in patients with infected TKAs, while arthroscopic debridement does not appear to be effective for infected TKA. Implant retention was difficult in the presence of resistant microorganisms. Two-stage revision was required in patients with type IV infection, with a success rate of 75%

Introduction. Open hip debridement surgery has been used for treatment of femoral acetabular impingement pain for over ten years in our unit. While literature has reported promising short term outcomes, longer term outcomes are more sparsely reported. We aim to assess survivorship and functional outcome at ten years, in patients who have undergone open hip debridement. Patients/Materials & Methods. All patients who had undergone open debridement surgery were identified on our database. The electronic, radiographic and paper records were reviewed. Demographic data, radiological and operative findings were recorded. All patients underwent ten year review with a standardised AP hips radiograph, questionnaire, non-arthritic hip score (NAHS), oxford hip score (OHS) and SF12 score. Results. A total of 1626 operations were identified of which 37 had reached the tenth anniversary of their surgery. There were 14 females and 22 males. The average age was 41. 10 (45%) had undergone subsequent hip arthroplasty. Those who underwent hip arthroplasty were older at initial surgery than those who survived. However, this was not statistically significant (p= 0.127). Those who failed had a higher Tonnis and UCLA grade at time of surgery. The majority failed within the first 2 years. In those whose hip survived, the average NAHS was 87. 100% of survivors deemed there surgery to have been worthwhile. Discussion. These results represent the first cohort of our patients to reach ten year follow up. The results represent a learning curve in patient selection. It is unsurprising that those with more arthritic change were more likely to fail. Conclusion. In patients with clearly defined CAM impingement without joint space narrowing, open hip debridement remains an operation with worthwhile outcomes at ten years

In 2019, the incidence of fractures were 178 million globally, South Africa accounting for close to 600 000 of these fractures, an 18.53% increase since 1990. South Africa does not have the public infrastructure to adequately facilitate the optimal surgical management of this burden. This forces intensive labour practices among orthopaedic surgeons, often performing complex surgeries throughout the night. There is a direct correlation between “after-hour”operations and the increase in morbidities. A retrospective review of the orthopaedic surgical cases and orthopaedic surgical emergencies done at a tertiary institution in Johannesburg between 8th of August 2021 to 12th December 2022. The nature of the orthopaedic interventions, the date of booking of the surgical procedures, date of surgical procedures, as well as start and end time of the orthopaedic interventions were analysed. “After-Hours” orthopaedic interventions were defined as interventions done between 16:00 and 07:00. Orthopaedic emergencies were defined as: Open fracture debridements, external Fixator insertion, arthrotomies, fasciotomies and the insertion of steinmann pins. 1483 (27.92%) of 5310 operative cases done on the emergency board were orthopaedic cases. 1098 (74.04%) hardware-related cases and 535 (36.08%) orthopaedic emergencies were done. 854 (57.58%) cases were done “After-Hours” of which 433 (29.20%) cases were done during “Dead-Hours” (23:00–07:00). Of these 433 cases, only 173 (39.95%) were true orthopaedic emergencies. Although the proportion of emergencies done after hours were greater than during working hours, there is still a large proportion of intricate orthopaedic cases done between 16:00– 07:00 that should not be prioritized, due to an associated higher morbidity. Enhanced strategic planning is advisable in future in order to prioritize complex hardware cases during working hours, and due to the burden, prioritize minor relooks and simple skin- grafts for the latter aspects of the night. A dedicated Orthopaedic Trauma theatre is recommended

Prosthetic joint infections (PJI) caused by Streptococcus species are relatively common. The aim of our study was to assess outcome after treatment for early and late PJI with Streptococcus species after a follow-up of two years. For this study we retrospectively included all patients with primary or revision total knee arthroplasty (TKA) or total hip (THA) arthroplasty, a minimum of two periprosthetic tissue cultures positive for Streptococcus species and a minimum follow-up of one year. According to international guidelines patients were classified as having early or late PJI. All patients with an early PJI were treated according to a standard treatment protocol, i.e. debridement and retention of the prosthesis, followed by adequate antibiotic therapy. Patients with late PJI underwent a debridement followed by adequate antibiotic therapy or joint revision. Patients’ hospital records were reviewed and we evaluated the status of the original prosthesis after an infection. Forty cases were included; 24 early and 16 late PJI. For early PJI, open debridement was performed in all patients, after a mean of 19 (range: 9 – 80) days. At final follow-up 21 prostheses (88%) were still in situ and without clinical signs of infection. Eight cases (41%) of late PJI were successfully treated with debridement and retention. Nine patients (59%) underwent a one- or two-stage revision. At final follow-up 16 patients (100%) with late PJI had a prosthesis in situ. Streptococcus dysgalactiae species accounted for more than 50% of the early infections, followed by Streptococcus agalactiae with 30%. In case of PJI with Streptococcus species open debridement and retention of the prosthesis should be performed followed by adequate and long-term antibiotic treatment. As expected, the retention rate for early PJI is much higher than that for late PJI

We retrospectively identified 18 consecutive patients with synovial chrondromatosis of the shoulder who had arthroscopic treatment between 1989 and 2004. Of these, 15 were available for review at a mean follow-up of 5.3 years (2.3 to 16.5). There were seven patients with primary synovial chondromatosis, but for the remainder, the condition was a result of secondary causes. The mean Constant score showed that pain and activities of daily living were the most affected categories, being only 57% and 65% of the values of the normal side. Surgery resulted in a significant improvement in the mean Constant score in these domains from 8.9 (4 to 15) to 11.3 (2 to 15) and from 12.9 (5 to 20) to 18.7 (11 to 20), respectively (unpaired t-test, p = 0.04 and p < 0.0001, respectively). Movement and strength were not significantly affected. Osteoarthritis was present in eight patients at presentation and in 11 at the final review. Recurrence of the disease with new loose bodies occurred in two patients from the primary group at an interval of three and 12 years post-operatively. In nine patients, loose bodies were also present in the bicipital groove; seven of these underwent an open bicipital debridement and tenodesis. We found that arthroscopic debridement of the glenohumeral joint and open debridement and tenodesis of the long head of biceps, when indicated, are safe and effective in relieving symptoms at medium-term review

Deep infection represents one of the most devastating complications of total knee arthroplasty. Commonly implicated organisms are gram positive bacteria such as staphylococcus aureus, staphylococcus epidermidis and group B streptococcus. Occasionally, infection may be caused by rare organisms, particularly in the immunocompromised host. We present a case of infected total knee arthroplasty in a penicillin allergic patient, caused by Pasteurella multocida, 13 weeks after the initial surgery. This was treated by open debridement and change of insert as well as aggressive antibiotic therapy. The patient admitted contact with a cat and three dogs at home. Pasteurella multocida is a facultatively anaerobic gram negative coccobacillus. It is a commensal in the nasopharygeal tract of domestic pets such as cats and dogs. Human infection can often be attributed to a bite or scratch. Prosthetic joint infection caused by Pasteurella is uncommon. Only a few cases have been reported in the literature. Our case has several learning points: (1) It is very important to definitively identify Pasteurella because standard therapy for prosthetic joint infection (e.g. flucloxacillin or vancomycin) is not optimal for this species.(2) Pasteurella are susceptible to penicillin, but the optimal antibiotic therapy for infections in patients allergic to beta lactam antibiotics is uncertain. A combination of ciprofloxacin and linezolid is recommended. (3) There is no consensus regarding appropriate management. There are reports of washout and antibiotic therapy alone, single and two stage revision procedures. In our case, at five months follow up, open debridement and change of insert along with antibiotic treatment appears to have been effective, although more long term follow up is required. (4)Post arthroplasty, all patients with pets at home should be advised to seek medical attention following any bite or scratch so that timely prophylaxis can be administered before sepsis becomes deep-seated

Introduction. Up to 2% of total knee arthroplasties (TKA) are still complicated by infection. This leads to dissatisfied patients with poor function, and has far-reaching social and economic consequences. The challenge in these cases is the eradication of infection, the restoration of full function and the prevention of recurrence. We report the outcome of prosthesis sparing early aggressive debridement in the acutely infected TKA. Methods. We studied 29 consecutive patients referred with acutely infected TKA (18 primaries, 11 revisions) which occurred within 6 weeks of the index operation or of haematogenous spread. Microbiology confirmed bacterial colonisation in all cases with 20 early post-operative infections and 9 cases of acute haematogenous spread. All patients underwent aggressive open debridement, a thorough synovectomy and a change of insert. Antibiotics were continued until inflammatory markers and the plasma albumin concentration returned to within normal limits. Results. Three patients required multiple washouts. 8 patients needed a two stage revision. 21 patients returned to their expected functional level without removal of the implants and with no radiographic evidence of prosthetic failure. At a minimum 2 years follow-up, we had a 72% infection control rate. The outcome was significantly better in patients treated in the first 120 hours after presentation. Conclusion. Our data suggests that there is a role for early aggressive open debridement in acute infections after TKA with an excellent chance of prosthesis salvage

Introduction. Up to 2% of total hip arthroplasties (THA) are still complicated by infection. This leads to dissatisfied patients with poor function, and has far-reaching social and economic consequences. The challenge in these cases is the eradication of infection, the restoration of full function and the prevention of recurrence. We report the outcome of early aggressive debridement in the acutely infected THA. Methods. We studied 28 consecutive patients referred with acutely infected THA (18 primaries, 10 revisions) which occurred within 6 weeks of the index operation or of haematogenous spread between 1999 and 2006. Microbiology confirmed bacterial colonisation in all cases with 20 early post-operative infections and 8 cases of acute haematogenous spread. Patients with a cemented THA underwent aggressive open debridement, a thorough synovectomy and exchange of all mobile parts. Uncemented THA were treated as a single stage revision with removal of all implants, aggressive debridement and re-implantation of new prosthesis. Antibiotics were continued in all cases until inflammatory markers and the plasma albumin concentration returned to within normal limits. Results. Ten patients required multiple washouts. 7 patients needed a two stage revision. 21 patients returned to their expected functional level without removal of the implants and with no radiographic evidence of prosthetic failure. At a minimum 2 years follow-up, we had a 75% infection control rate. The outcome was significantly better in patients treated in the first 120 hours after presentation. Discussion and Conclusion. Our data suggests that there is a role for early aggressive open debridement in acute infections after THA with an excellent chance of eradicating infection
