Aim

Deep infection following endoprosthetic replacement (EPR) of long bones is a devastating complication occurring in 15% of musculoskeletal tumour patients. The recently published PARITY Trial demonstrated that extending antibiotic prophylaxis from 24 hours to 5 days does not reduce infection rates. However, questions remain about the optimal antibiotic choice and dose.

Method

A 23-question multiple-choice questionnaire was designed and piloted through an iterative feedback process until the final version was agreed by all authors. Open and closed-ended questions were used to gather information on practice and Likert-type scale responses were used to grade responses to ascertain surgeon perceptions and preferences. The online survey was sent to all surgeon delegates of the 34th Annual Meeting of the European Musculo-Skeletal Oncology Society in London in October 2022.

The recently published Prophylactic Antibiotic Regimens In Tumor Surgery (PARITY) trial found no benefit in extending antibiotic prophylaxis from 24 hours to five days after endoprosthetic reconstruction for lower limb bone tumours. PARITY is the first randomized controlled trial in orthopaedic oncology and is a huge step forward in understanding antibiotic prophylaxis. However, significant gaps remain, including questions around antibiotic choice, particularly in the UK, where cephalosporins are avoided due to concerns of Clostridioides difficile infection. We present a review of the evidence for antibiotic choice, dosing, and timing, and a brief description of PARITY, its implication for practice, and the remaining gaps in our understanding.

Primary malignant bone and soft tissue tumours often occur in the lower extremities of active individuals including children, teenagers and young adults. Survivors routinely face long-term physical disability. Participation in sports is particularly important for active young people but the impact of sarcoma treatment is not widely recognised and clinicians may be unable to provide objective advice about returning to sports. We aimed to identify and summarise the current evidence for involvement in sports following treatment of lower limb primary malignant bone and soft tissue tumours.

A comprehensive search strategy was used to identify relevant studies combining the main concepts of interest: (1) Bone/Soft Tissue Tumour, (2) Lower Limb, (3) Surgical Interventions and (4) Sports. Studies were selected according to eligibility criteria with the consensus of three authors. Customised data extraction and quality assessment tools were used.

22 studies were selected, published between 1985 – 2020, and comprising 1005 patients. Fifteen studies with data on return to sports including 705 participants of which 412 (58.4%) returned to some form of sport at a mean follow-up period of 7.6 years. Four studies directly compared limb sparing and amputation; none of these were able to identify a difference in sports participation or ability.

Return to sports is important for patients treated for musculoskeletal tumours, however, there is insufficient published research to provide good information and support for patients. Future prospective studies are needed to collect better pre and post-treatment data at multiple time intervals and validated clinical and patient sports participation outcomes such as type of sports participation, level and frequency and a validated sports specific outcome score, such as UCLA assessment. In particular, more comparison between limb sparing and amputation would be welcome.

Aims

The proximal tibia (PT) is the anatomical site most frequently affected by primary bone tumours after the distal femur. Reconstruction of the PT remains challenging because of the poor soft-tissue cover and the need to reconstruct the extensor mechanism. Reconstructive techniques include implantation of massive endoprosthesis (megaprosthesis), osteoarticular allografts (OAs), or allograft-prosthesis composites (APCs).

Methods

This was a retrospective analysis of clinical data relating to patients who underwent proximal tibial arthroplasty in our regional bone tumour centre from 2010 to 2018.

Aims

The incidence of bone metastases is between 20% to 75% depending on the type of cancer. As treatment improves, the number of patients who need surgical intervention is increasing. Identifying patients with a shorter life expectancy would allow surgical intervention with more durable reconstructions to be targeted to those most likely to benefit. While previous scoring systems have focused on surgical and oncological factors, there is a need to consider comorbidities and the physiological state of the patient, as these will also affect outcome. The primary aim of this study was to create a scoring system to estimate survival time in patients with bony metastases and to determine which factors may adversely affect this.

Methods

This was a retrospective study which included all patients who had presented for surgery with metastatic bone disease. The data collected included patient, surgical, and oncological variables. Univariable and multivariable analysis identified which factors were associated with a survival time of less than six months and less than one year. A model to predict survival based on these factors was developed using Cox regression.

Aims

Hydroxyapatite (HA)-coated collars have been shown to reduce aseptic loosening of massive endoprostheses following primary surgery. Limited information exists about their effectiveness in revision surgery. The aim of this study was to radiologically assess osteointegration to HA-coated collars of cemented massive endoprostheses following revision surgery.

Methods

Retrospective review of osseointegration frequency, pattern, and timing to a specific HA-coated collar on massive endoprostheses used in revision surgery at our tertiary referral centre between 2010 to 2017 was undertaken. Osseointegration was radiologically classified on cases with a minimum follow-up of six months.

Aims

The primary aim of this study was to assess the rate of patient satisfaction one year after total knee arthroplasty (TKA) according to the focus of the question asked. The secondary aims were to identify independent predictors of patient satisfaction according to the focus of the question.

Patients and Methods

A retrospective cohort of 2521 patients undergoing a primary unilateral TKA were identified from an established regional arthroplasty database. Patient demographics, comorbidities, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and 12-Item Short-Form Health Survey (SF-12) scores were collected preoperatively and one year postoperatively. Patient satisfaction was assessed using four questions, which focused on overall outcome, activity, work, and pain. Logistic regression analysis was used to identify independent preoperative predictors of increased stiffness when adjusting for confounding variables.

Aims

The primary aim of this study was to assess whether patient satisfaction one year after total knee arthroplasty (TKA) changed with longer follow-up. The secondary aims were to identify predictors of satisfaction at one year, persistence of patient dissatisfaction, and late onset dissatisfaction in patients that were originally satisfied at one year.

Patients and Methods

A retrospective cohort consisting of 1369 patients undergoing a primary TKA for osteoarthritis that had not undergone revision were identified from an established arthroplasty database. Patient demographics, comorbidities, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, and Short Form 12 (SF-12) questionnaire scores were collected preoperatively, and one and five years postoperatively. In addition, patient satisfaction was assessed at one and five years postoperatively. Logistic regression analysis was used to identify independent predictors of satisfaction at one and five years.

Background

Myxofibrosarcomas are malignant soft tissue tumours that often present as painless slowly growing masses in the extremities of older males. Locally infiltrative growth means risks of local recurrence is high. Management emphasises negative surgical margins and adjuvant therapy. The aim of this retrospective case series was to review our experience of this tumour, and make recommendations about a minimum resection margin and how best to utilise the expertise of the multidisciplinary team.

Methods

A computerised database identified patients with myxofibrosarcoma surgically treated in our centre between 1997 and 2011. Clinical records were reviewed. Margins were positive if tumour was at or within 1mm of the resection plane.

Background

Membrane type 1 matrix metalloproteinase (MT1-MMP) plays a role in the progression of several common solid cancers. Given that osteosarcoma features extensive local invasion and haematogenous metastases, we hypothesised that osteosarcoma cells utilise MT1-MMP to drive these processes. Moreover, since hypoxia regulates MT1-MMP expression in breast cancer we investigated the effects of hypoxia on MT1-MMP expression in osteosarcoma cells.

Aims

Examination of MT1-MMP expression in osteosarcoma biopsy tissue in relation to clinical outcome

Assessment of MT1-MMP, together with hypoxia inducible factors HIF-1α and HIF-2α expression in a panel of osteosarcoma cell lines under normoxia and hypoxia

Introduction

Aseptic loosening is the most common mode of failure of massive endoprostheses. Introduction of Hydroxyapatite coated collars have reduced the incidence of aseptic loosening. However bone growth is not always seen on these collars.

Objectives

The aims of our study were to determine the extent of osseous integration of Hydroxyapatite coated collars, attempt a grading system for bone growth and to determine the effect of diagnosis, surgical technique and adjuvant therapy on bone growth.

Introduction

We aimed to determine the extent of osseous integration of the hydroxyapatite collars of tumour endoprostheses implanted in our unit.

Methods

We identified 57 patients who had massive endoprostheses implanted over the last six years and reviewed clinical records and x-rays. There were 20 proximal femoral, 23 distal femoral, 6 proximal tibial, 8 proximal humeral and 1 distal humeral replacements. Patients fell into three groups: 1.Primary bone tumours, 2. Metastatic bone tumours and 3. Non-tumour indications

Introduction

Angiosarcomas are rare aggressive sarcomas of vascular endothelial origin. These tumours have the potential to be multicentric and are associated with high rates of local recurrence, which makes treatment challenging. The gold-standard is that these patients are managed in specialist centres by a multidisciplinary team. We present our experience of managing patients with angiosarcoma in the North of England Bone and Soft Tissue Tumour Service and a review of the literature.

Methods

A prospectively collated electronic database was used to identify patients with angiosarcoma treated between 2000 and 2008, and an analysis performed of demographics, anatomical site, surgical excision and reconstruction, local disease recurrence and metastatic disease.

Aims

Malignant tumours of the foot and ankle are rare, but easily missed. NICE guidelines for bone and soft tissue tumours may be less appropriate for the foot and ankle than elsewhere. The purpose of this study was to identify the clinical features and treatment of malignant tumours arising in the foot and ankle to see if guidelines should be modified.

Patient and Methods

This was a retrospective review of patients presenting to the Bone and Soft Tissue Tumour Service with a suspected tumour of the foot or ankle. Between March 1998 and July 2009, 132 patients were identified from a prospectively collected database of patients reviewed at a weekly multidisciplinary meeting.

Introduction

The Two Week Waiting Time Standard, which requires that patients with suspected cancer referred by general practitioners should be seen within 2 weeks, was introduced in 2000. We reviewed the performance of this standard with regards to proportion of patients seen and tumour detection rates.

Methods and results

We reviewed all the referrals sent under the ‘two week’ rule from January 2004 to December 2005, to our bone and soft tissue sarcoma service. These referrals were evaluated for:

Whether or not the referral met established referral guidelines for bone and soft tissue tumours

The proportion of patients seen within two weeks

The proportion of patients referred under the guidelines that had malignant tumours.

This was compared with the total number of referrals to the unit and their tumour detection rates.

A total of 40 patients were referred under the ‘two week’ rule. 95% of these were seen within two weeks of referral. Of the 40 patients, three patients had soft tissue metastasis from a primary tumour elsewhere, and six had primary malignant soft tissue tumours. 13 had a benign bone/ soft tissue tumour. 18 (45%) patients had a non neoplastic pathology (6 Muscle tear/ herniation; 4 ganglion/bursa; 2 lumps that disappeared) During the same period a total of 507 patients were referred by other routes.

Introduction and Aims: Morbid obesity (BMI> 40) has been shown to cause increased perioperative morbidity and poorer long-term implant survivorship following total knee arthroplasty (TKA). The aim of this study was to determine the impact of morbid obesity on patient-reported outcomes following TKA.

Methods: Patients undergoing primary TKA were invited to complete questionnaires preoperatively and one year after surgery. Questionnaires include the WOMAC and SF-36 health status measures, demographics, self-reported comorbid medical conditions, height and weight. At follow-up, satisfaction with results of TKA is included. Patients were categorised by their preoperative BMI categories as ideal weight (20–25), overweight (> 25–30), obese (> 30–40) or morbidly obese (> 40). We used multivariate analysis to adjust for known significant correlates of WOMAC and SF-36, namely age, gender and comorbid medical conditions. Adjusted mean scores for each assessment were compared by BMI category.

Results: A total of 769 patients were included in the study which included 27 morbidly obese, 280 obese, 314 overweight and 148 ideal weight patients. Morbidly obese patients when compared with non-obese patients had significantly worse preoperative WOMAC pain and function and a trend for worse SF36 scores (Vitality significantly worse, p=0.04). There was no significant difference between the BMI categories at one year for WOMAC or SF-36 scores (trend for the Physical Functioning score to be lower, p=0.052). Morbidly obese patients were all satisfied with pain relief after surgery but were less satisfied with functional results when compared to the non-obese groups.

Discussion: This study shows that morbidly obese patients report significantly worse health status prior to TKA but their post-operative improvement is greater than the non-obese population. Although morbid obesity should not be an absolute contraindication to TKA, patients should be carefully selected balancing the risk of perioperative complications and earlier failure against the demonstrated marked improvement in quality of life.
