The outcome of an anatomical shoulder replacement
depends on an intact rotator cuff. In 1981 Grammont designed a novel
large-head reverse shoulder replacement for patients with cuff deficiency.
Such has been the success of this replacement that it has led to
a rapid expansion of the indications. We performed a systematic
review of the literature to evaluate the functional outcome of each
indication for the reverse shoulder replacement. Secondary outcome
measures of range of movement, pain scores and complication rates
are also presented.
Meniscus repair is now an accepted procedure, but many questions remain, regarding the results, indications versus meniscal resection. How to assess the results of meniscal repair?. Clinical results doesn’t allow to assess the healing rate. Some failure of healing can be asymptomatic. There is thus a need for an objective assessment of the healing process: by arthroscopy (but it is invasive); by MRI but the hypersignal in the meniscus area is difficult to interpret. The best way seems to be arthro CT, even if it is a quite invasive technique.

There is a paucity of data available for the use of Total Femoral Arthroplasty (TFA) for joint reconstruction in the non-oncological setting. The aim of this study was to evaluate TFA outcomes with minimum 5-year follow-up. This was a retrospective database study of TFAs performed at a UK tertiary referral revision arthroplasty unit. Inclusion criteria were patients undergoing TFA for non-oncological indications. We report demographics, indications for TFA, implant survivorship, clinical outcomes, and indications for re-operation. A total of 39 TFAs were performed in 38 patients between 2015–2018 (median age 68 years, IQR 17, range 46–86), with 5.3 years’ (IQR 1.2, 4.1–18.8) follow-up; 3 patients had died. The most common indication (30/39, 77%) for TFA was periprosthetic joint infection (PJI) or fracture-related infection (FRI); and 23/39 (59%) had a prior periprosthetic fracture (PPF). TFA was performed with dual-mobility or constrained cups in 31/39 (79%) patients. Within the cohort, 12 TFAs (31%) required subsequent revision surgery: infection (7 TFAs, 18%) and instability (5 TFAs, 13%) were the most common indications. 90% of patients were ambulatory post-TFA; 2 patients required disarticulation due to recurrent PJI. While 31/39 (79%) were infection free at last follow-up, the remainder required long-term suppressive antibiotics. This is the largest series of TFA for non-oncological indications. Though TFA has inherent risks of instability and infection, most patients are ambulant after surgery. Patients should be counselled on the risk of life-long antibiotics, or disarticulation when TFA fails.
Infections represent a devastating complication in orthopedic and traumatological surgery, with high rates of morbidity and mortality. An early intervention is essential, and it includes a radical surgical approach supported by targeted intravenous antimicrobial therapy. The availability of parenteral antibiotics at the site of infection is usually poor, so it is crucial to maximize local antibiotic concentration using local carriers. Our work aims to describe the uses of one of these systems, Stimulan®, for the management and prevention of infections at our Institution. Analysing the reported uses of Stimulan®, we identified two major groups: bone substitute and carrier material for local antibiotic therapy. The first group includes its application as a filler of dead spaces within bone or soft tissues resulting from traumatic events or previous surgery. The second group comprehends the use of Stimulan® for the treatment of osteomyelitis, post-traumatic septic events, periprosthetic joint infections, arthroplasty revision surgery, prevention in open fractures, surgery of the diabetic foot, oncological surgery and for all those patients susceptible to a high risk of infection. We used Stimulan® in several complex clinical situations: in PJIs, in DAPRI procedure and both during the first and the second stage of a 2-stage revision surgery; furthermore, we started to exploit this antibiotic carrier also in prophylaxis of surgical site infections, as it happens in open fractures, and when a surgical site remediation is required, like in osteomyelitis following ORIF. Stimulan® is an extremely versatile and polyhedric material, available in the form of beads or paste, and can be mixed to a very broad range of antibiotics to better adapt to different bacteria and their antibiograms, and to surgeon's needs. These properties make it a very useful adjuvant for the management of complex cases of infection, and for their prevention, as well.
Introduction: Revision Hip Surgery presents an increasing Orthopaedic Burden.
Introduction: Lesser toe problems and metatarsalgia are common complaints in patients presenting with foot problems. Associated toe deformities include mallet toes, hammer toes, claw toes. The patient may complain of pain over the proximal interphalangeal joint from shoe ware, diffuse or localized pain under the metatarsal heads, or swelling and irritation of the metatarsophalangeal joint. Most patients can be treated with shoe ware modification, NSAID medication, tapping of toes, orthotics, or steroid injections. Surgical treatment includes flexor to extensor transfers, PIP excision arthroplasty, plantar condylectomy and metatarsal osteotomy.
Revision knee arthroplasty is a complex procedure with the number and cost of knee revision procedures performed per year expected to rise. Few studies have examined adverse events following revision arthroplasty. The objective of this study was to determine rates of serious adverse events in patients undergoing revision knee arthroplasty with consideration of the indication for revision (urgent versus elective indications) and to compare these with primary arthroplasty and re-revision arthroplasty. Patients undergoing primary knee arthroplasty were identified in the UK Hospital Episode Statistics. Subsequent revision and re-revision arthroplasty procedures in the same patients and same knee were identified. The primary outcome was 90-day mortality and a logistic regression model was used to investigate factors associated with 90-day mortality and secondary adverse outcomes including infection (undergoing surgery), pulmonary embolism, myocardial infarction, stroke. Urgent indications for revision arthroplasty were defined as infection or fracture, and all other indications were included in the elective indications cohort. 939,021 primary knee arthroplasty cases were included of which 40,854 underwent subsequent revision arthroplasty, and 9,100 underwent re-revision arthroplasty. Revision surgery for elective indications was associated with a 90-day rate of mortality of 0.44% (135/30,826; 95% CI 0.37-0.52) which was comparable to primary knee arthroplasty (0.46%; 4,292/939,021; 95% CI 0.44-0.47). Revision arthroplasty for infection, however, was associated with a much higher mortality of 2.04% (184/9037; 95% CI 1.75-2.35; odds ratio [OR] 3.54; 95% CI 2.81-4.46), as was revision for periprosthetic fracture at 5.25% (52/991; 95% CI 3.94-6.82; OR 6.23; 95% CI 4.39-8.85). Higher rates of pulmonary embolism, myocardial infarction, and stroke were also observed in the infection and fracture cohort. These findings highlight the burden of complications associated with revision knee arthroplasty. They will inform shared decision-making for patients considering revision knee arthroplasty for elective indications. Patients presenting with infection of a knee arthroplasty or a periprosthetic fracture are at very high risk of adverse events. It is important that acute hospital services and tertiary referral centres caring for these patients are appropriately supported to ensure appropriate urgency and an anticipation for increased care requirements.
Purpose: Dwyer osteotomy remains controversial as shown by the numerous series reported. Conclusions have varied and there is no real consensus. The cause of these divergent opinions is related to the variability of indications (association or not with active neurological disease) and surgical schools. Interpretation of outcome and comparisons are hindered. Material and methods: We reviewed 22 cases of Dwyer osteotomy of the calcaneum performed between 1972 and 2002. The lateral approach was used for closed osteotomy. Mean follow-up was ten years (1–30). Patients were aged 8 to 55 years. The objective and subjective rating system of Laaveg and Panseti (1980) was used.
The collagenase of Clostridium Histolyticum enzyme infiltration is a mini-invasive treatment method for Dupuytren's disease which has emerged in recent years as an alternative to traditional surgery (selective aponeurectomy). Although both treatments are effective in the long term, a wider use of the enzyme is spreading worldwide.
The objective of this study was to determine rates of serious adverse events in patients undergoing revision knee arthroplasty with consideration of the indication for revision and compare these with primary knee arthroplasty. Primary and revision arthroplasty procedures were identified in the national Hospital Episode Statistics and were linked by patient and side. A logistic regression model was used to investigate factors associated with 90-day mortality (primary outcome) and secondary serious adverse outcomes. Urgent indications for revision arthroplasty were defined as infection or fracture; other indications (e.g. loosening, instability, wear) were included in the elective cohort.Abstract
Introduction
Methodology
Prosthetic joint infections (PJIs) of the hip and knee are associated with significant morbidity and socioeconomic burden. We undertook a systematic review of the current literature with the aim of proposing criteria for the selection of patients for a single-stage exchange arthroplasty in the management of a PJI. A comprehensive review of the current literature was performed using the OVID-MEDLINE, EMBASE, and Cochrane Library databases and the search terms: infection and knee arthroplasty OR knee revision OR hip arthroplasty OR hip revision, and one stage OR single stage OR direct exchange. All studies involving fewer than ten patients and follow-up of less than two years in the study group were excluded as also were systematic reviews, surgical techniques, and expert opinions.Aims
Material and Methods
Multiple myeloma may be associated with extensive bone destruction, impending or present pathological fracture, and intractable pain. However, surgical intervention is rarely indicated since local bone crises are effectively managed with chemotherapy and radiotherapy in the majority of the patients. The current retrospective analysis of patients who eventually required surgical intervention emphasized indications for surgery, surgical technique, and functional and oncological outcomes. Materials and Methods: Between 1982 and 2000, the authors operated on 18 patients with multiple myeloma. There were 11 females and 7 males whose age ranged from 4 to 67 years (median, 59 years). Anatomic locations: proximal humerus – 5, proximal femur – 4, distal femur – 5, proximal tibia – 3. One patient had total femur involvement. Preoperatively, 11 patients were treated with chemotherapy and 4 received radiotherapy. Seven patients were referred with a bone lesion as their initial presentation and, therefore, did not receive pre-operative treatment.
The purpose of this study was to compare implant survivorship and functional outcomes in patients undergoing reverse total shoulder arthroplasty (RTSA) for acute proximal humeral fracture (PHF) with those undergoing elective RTSA in a population-based cohort study. Prospectively collected data from the New Zealand Joint Registry from 1999 to 2021 and identified 7,277 patients who underwent RTSA. Patients were categorized by pre-operative indication, including acute PHF (10.1%), rotator cuff arthropathy (RCA) (41.9%), osteoarthritis (OA) (32.2%), rheumatoid arthritis (RA) (5.2%) and old traumatic sequelae (4.9%). The PHF group was compared with elective indications based on patient, implant, and operative characteristics, as well as post-operative outcomes (Oxford Shoulder Score [OSS], and revision rate) at 6 months, 5 and 10 years after surgery. Survival and functional outcome analyses were adjusted by age, sex, ASA class and surgeon experience.Introduction
Methods
Since 2012 we have routinely used the cementless Oxford medial unicompartmental knee arthroplasty (mUKA), with microplasty instrumentation, in patients with anteromedial osteoarthritis (AMOA) meeting modern indications. We report the 10-year survival of 1000 mUKA with minimum 4-year follow-up. National Joint Registry (NJR) surgeon reports were interrogated for each senior author to identify the first 1,000 mUKAs performed for osteoarthritis. A minimum of 4 years follow-up was required. There was no loss to follow-up. The NJR status of each knee was established. For each mUKA revision the indication and mechanism of failure was determined using local patient records. The 10-year implant survival was calculated using life-table analysis.Abstract
Background
Methods
The number of Americans over the age of 80 is increasing at a faster rate than that of the 65–80 population. The cohort age 85–94 years had the fastest rate of growth from 2000–2010. The number of Americans older than 95 years grew at approximately 26% during the same period. This rapid growth has been associated with an increasing incidence of osteoarthritis of the hip and knee in this population. This surge in the growth rate of the elderly population has coincided with an increasing demand for primary and revision total joint arthroplasty. Surgeons need to be prepared to perform safely and appropriately these procedures in this rapidly growing segment of the population. Surgeons need to be aware of the 1) clinical outcomes that can be expected when total joint procedures are performed in this group of patients; 2) the morbidity and mortality associated with the performance of these procedures; and 3) the relative cost effectiveness of these interventions. Clinical outcomes of TJA in this population are generally good. Pain and satisfaction scores are similar to those of younger patients. Although pre-operative pain and functional impairment scores are higher pre-operatively in elderly patients, these improve significantly following TJA. However, functional outcome scores decline noticeably after 5 years, reflecting the impact of coexistent comorbidities. The continued need for assistive devices is greater in this age group than in younger total joint patients. The risk of falls, a particular issue of concern in this age group, is reduced after total hip and knee surgery. The rate of complications, including mortality, following TJA in this age group is greater than in the 65–79-year-old group. The use of hospitalists to co-manage peri-operative care is particularly important in this age group. The increased rate of complications is associated with longer lengths of stay. However, the length of stay for this age group after primary total joint replacement is decreasing significantly; reflecting the widespread streamlining of peri-operative care that is being incentivised and implemented nationwide. The use of extended care facilities is also greater in this age group. The performance of revision TJA in this age group is particularly challenging. The rates of revision in elderly patients are anticipated to rise significantly in coming years. Although revision TJA is associated with significant pain relief and patient satisfaction, it is accompanied by mortality and complication rates that are substantially greater than those in younger age groups.
For which patients is bone-defect-reconstruction with the Masquelet-technique suitable? Between 11/2011 and 1/2015 we treated 27 Patients (4 female/ 23 male) with bone-defects up to 150mm after septic complications with the Masquelet-technique. Reason of the bone defects were infected-non-unions of lower extremity, chronic osteomyelitis, infected knee-arthrodesis, chronic upper-ancle-empyema and infect-defect-non-union of the humerus. On average the patients were 47,5 (18–74) years old. The mean bone-defect-size was 62,6 mm (25–150). 26 of the 27 patients came from other hospitals, where they had up to 20 (mean 4,9) operations caused by the infection. The time before transfer to our hospital was on average 177days (6–720). 25 patients receaved flaps because of soft tissue-defects (7 free flaps, 18 local flaps). 13 patients suffered a polytrauma. In 5 cases the femur, in 3 cases a knee-arthrodesis, in 18 cases the tibia and in 1 case the humerus was affected by infection resulting in bone defects. Indication for the Masquelet-technique was low-/incompliance in 10 cases due to higher grade of traumatic brain injury and polytrauma and difficult soft-tissue conditions, in 6 times after problems with segment-transport and in 1 case as dead space management. Positiv microbial detection succeeded in 19 patients at the first operation although most of the patients underwent long term antibiotic therapy. Mainly we found problematic bacteria. At the time of defect reconstruction with spongious graft we found persistant bacteria in 4 cases. The first operation aimed treating the infection with radical sequestrectomy, removal of foreign bodies and filling the defect with an antibiotic loaded cementspacer as well as external fixation. 6–8 weeks later we removed the spacer and filled the defect with autologous bonegraft. In 2 cases we needed 2 bone grafts to fill the defect. In 9 cases we removed the fixateur and stabilized the defect with an internal anglestable plate. All patients were examined clinically and radiologically every 4–6 weeks in our outpatient-department for osteitis until full weight bearing and later every 3months In 22 of 27 cases the infection was clinically treated successfully. 5 patients are allowed for full weight bearing (all with secondary internal plates). No patient underwent amputation. There were 4 recurrences of infection, 9 instabilities needing internal stabilization and further bonegraft. For patients with low-/incompliance for various reasons and for those with difficult soft tissue conditions following flaps the Masquelet technique is a valuable alternative to the normal autologious spongegraft and to the segmenttransport. Internal fixation seems necessary.
Metal-on-metal bearing surfaces were used frequently until recently because of the potential for decreased wear and the ability to use large femoral heads which can reduce instability. However, data reported in the Australian registry over the past 5 years demonstrated an increase in failure rates compared to metal-on-polyethylene bearings. In addition, adverse local tissue reactions (ALTR) associated with pseudotumors and destruction of the soft tissue around the joint have led to revision of these implants. Unfortunately, at the present time there is no optimal management strategy that has been delineated for metal-on-metal implants because of a lack of evidence. The biologic response to metal-on-metal implants is usually local but may be systemic. The management of these patients is complex because patients may have pseudotumors and/or elevated metal ion levels and be asymptomatic. In addition, there are a number of intrinsic causes (loosening, infection, iliopsoas tendinitis) and extrinsic causes (spinal disease, trochanteric bursitis) that can be a source of pain. There is no evidenced based approach to manage these patients and no single test should be used to determine treatment. A thorough clinical evaluation is essential and blood tests are necessary to rule out infection. Imaging studies including plain radiographs and a MARS MRI are needed to evaluate either the stability of the prosthesis and to assess for the presence of pseudotumors and soft tissue destruction around the implant. Patients with symptomatic hips and evidence of muscle involvement on MRI require revision. Finally, the clinician must always be aware of the potential for systemic effects which require early and aggressive intervention to limit the adverse response to the metal and the metal bearing.
