It is undetermined which factors predict return to work following arthroscopic rotator cuff repair. We aimed to identify which factors predicted return to work at any level, and return to pre-injury levels of work 6 months post-arthroscopic rotator cuff repair. Multiple logistic regression analysis of prospectively collected demographic, pre-injury, preoperative, and intraoperative data from 1502 consecutive primary arthroscopic rotator cuff repairs, performed by a single surgeon, was performed to identify independent predictors of return to work, and return to pre-injury levels of work respectively, 6 months post-surgery. Six months post-rotator cuff repair, 76% of patients returned to work (RTW), and 40% returned to pre-injury levels of work (Full-RTW). RTW at 6 months was likely if patients were still working after their injuries, but prior to surgery (Wald statistic [W]=55, p<0.0001), were stronger in internal rotation preoperatively (W=8, p=0.004), had full-thickness tears (W=9, p=0.002), and were female (W=5, p=0.030). Patients who achieved Full-RTW were likely to have worked less strenuously pre-injury (W=173, p<0.0001), worked more strenuously post-injury but pre-surgery (W=22, p<0.0001), had greater behind-the-back lift-off strength preoperatively (W=8, p=0.004), and had less passive external rotation range of motion preoperatively (W=5, p=0.034). Patients who were still working post-injury, but pre-surgery were 1.6-times more likely to RTW than patients who were not (p<0.0001). Patients who nominated their pre-injury level of work as “light” were 11-times more likely to achieve Full-RTW than those who nominated “strenuous” (p<0.0001). Six months post-rotator cuff repair, a higher patient-rated post-injury, but pre-surgery level of work was the strongest predictor of RTW. A lower patient-rated pre-injury level of work was the strongest predictor of Full-RTW. Greater preoperative subscapularis strength independently predicted both RTW, and Full-RTW

Purpose. The purpose of this study was to investigate the rate of return to work after total knee arthroplasty (TKA). Materials and Methods. 105 knees of 80 cases were tested after TKA surgery. 18 knees of 14 cases were men and 87 knees of 66 cases were women. The average age at the time of surgery was 71.5 years, and the average postoperative observation period was 25.5 months. All patients were with osteoarthritis of the knee. The use models were Hi-tech Knee II (Nakashima Medical, Okayama, Japan) CR type 99 knees and PS type 6 knees. The rate of return to work after surgery and employment rate of before and after surgery were examined for all cases. In addition,[1]age at surgery [2]ROM [3]JKOM score(Akai 2006) [4]Knee Society score (KSS Insall 1989) were examined in each case, and found the factors influenced on employment rate after TKA. The occupation was classified using major group of the International Standard Classification of Occupations (ISCO-08) defined by International Labour Organization (ILO) on 2007. Mann-Whitney U test was used for the statistical work. Results. Preoperative and postoperative employment state was shown in the Fig.1. 29 knees of 23 cases were in employment before surgery. In these cases, 22 knees of 18 cases had return to work after surgery (Group I) and 7 knees of 5cases had retired after surgery(Group II). 76 knees of 57cases were unemployed before and after surgery(Group III). Return to work rate was 78.3 percent after TKA. In the Group I, all cases returned to the same occupation before surgery. The average age of the Group III at the time of surgery was significantly higher than Group I and II(Fig.2). Compared KSS, postoperative functional score of the group I was significantly higher than Group II and III(Fig.3). Discussion. The cases employed before TKA were younger than the unemployed cases. In the cases returned to work after TKA, stairs rise-and-fall capability and walking ability were higher than the other cases. Conclusion. (1)The rate of return to work was 78.3 percent after TKA.(2)Age at surgery influenced the preoperative employment.(3)Stairs rise-and-fall capability and walking ability after surgery involved the return to work

Aims. COVID-19-related patient care delays have resulted in an unprecedented patient care backlog in the field of orthopaedics. The objective of this study is to examine orthopaedic provider preferences regarding the patient care backlog and financial recovery initiatives in response to the COVID-19 pandemic. Methods. An orthopaedic research consortium at a multi-hospital tertiary care academic medical system developed a three-part survey examining provider perspectives on strategies to expand orthopaedic patient care and financial recovery. Section 1 asked for preferences regarding extending clinic hours, section 2 assessed surgeon opinions on expanding surgical opportunities, and section 3 questioned preferred strategies for departmental financial recovery. The survey was sent to the institution’s surgical and nonoperative orthopaedic providers. Results. In all, 73 of 75 operative (n = 55) and nonoperative (n = 18) providers responded to the survey. A total of 92% of orthopaedic providers (n = 67) were willing to extend clinic hours. Most providers preferred extending clinic schedule until 6pm on weekdays. When asked about extending surgical block hours, 96% of the surgeons (n = 53) were willing to extend operating room (OR) block times. Most surgeons preferred block times to be extended until 7pm (63.6%, n = 35). A majority of surgeons (53%, n = 29) believe that over 50% of their surgical cases could be performed at an ambulatory surgery centre (ASC). Of the strategies to address departmental financial deficits, 85% of providers (n = 72) were willing to work extra hours without a pay cut. Conclusion. Most orthopaedic providers are willing to help with patient care backlogs and revenue recovery by working extended hours instead of having their pay reduced. These findings provide insights that can be incorporated into COVID-19 recovery strategies. Level of Evidence: III. Cite this article: Bone Jt Open 2021;2(7):562–568

Background. Both anatomic (TSA) and reverse shoulder arthroplasty (RSA) are routinely performed for patients whom desire to continue to work or participate in sports. The purpose of this study is to analyze and compare the ability of patients to work and participate in sports based on responses to clinical outcome surveys. Methods. A retrospective review of 335 patients treated with TSA (179 patients) and RSA (156 patients) who completed questions 9 and 10 on the activity patient self-evaluation portion of the American Shoulder and Elbow Surgeons (ASES) Assessment Form was performed at average 30 months follow-up. Comparisons were made between TSA and RSA for the specific ASES score (rated 0–3) reported for usual work and sport, as well as ASES total score. Sports were subdivided based on those that predominantly use shoulder function. Results. Patients treated with TSA had a 32% greater ability to participate in sports (average specific ASES score 2.5 vs 1.9, p=0.001), with significantly higher scores for aquatic and sedentary sports (Figure 1). TSA patients demonstrated greater ability to participate in sports requiring shoulder function without difficulty, as 62% reported maximal scores (p=0.001) (Figure 2). TSA patients also demonstrated a 21% greater ability to perform work (average specific ASES score 2.6 vs. 2.1, p=0.001), with significantly higher scores for housework and gardening (Figure 3). Conclusion. Both TSA and RSA allow for participation in work and sport, with TSA patients reporting better overall ability to participate. For sports involving shoulder function, TSA patients more commonly report maximal ability to participate than RSA patients

Introduction. Cubital Tunnel syndrome is common affecting 1 in 4000 people. The cubital tunnel serves as major constraint for the ulna nerve. Cubital tunnel decompression is a relatively simple operation to resolve the patients' symptoms. There has been published data on return to work and normal activity after carpal tunnel decompression but not cubital tunnel. Method. All patients who underwent cubital tunnel decompression in Wirral University Teaching Hospital NHS Foundation Trust between September 2006 and September 2010 were identified and sent a questionnaire; enquiring about age, type of job & if it involved heavy lifting, time off work, range of movement at elbow and hand and if their symptoms resolved or if they had any other complications. Results. 106 cubital tunnels were decompressed in the 4 year period. 66 patients returned the questionnaire (62% response). The average age at operation was 59 years (32–86years). The average time to return to work after surgery was 10 days (0–300days). Complications included painful scar, return of symptoms and chronic region pain syndrome, which lead the patient to change jobs (300days). Only one patient was self-employed, they had no time off work. In 24 patients (36%) their symptoms either never resolved or returned, only worsening in 2 patientsstopping them returning to work their heavy manual jobs. The DASH score (work modules) post operatively was 38.3 over all working groups; this was lower in patients who didn't have a manual job. Conclusion. Our patients, returned to work at around 10 days after surgery. People with jobs which involved no heavy lifting returned at 5 days compared to that of 40 days, in patients with manual jobs. Now we can give our patients more accurate information about how long it will take them to return to work, depending on their job type

It is a not so uncommon clinical scenario: well-fixed, well-aligned, balanced total knee arthroplasty with continued pain. However, radiographs also demonstrate an unresurfaced patella. The debate continues and the controversy remains as whether or not to routinely resurface the patella in total knee arthroplasty. In perhaps the most widely referenced article on the topic, the overall revision rates were no different between the resurfaced (9%) and the unresurfaced (12%) groups and thus their conclusion was that similar results can be obtained with and without resurfacing. However, a deeper look in to the data in this study shows that 4 times more knees in the unresurfaced group were revised for patellofemoral problems.

A more recent study concluded that selectively not resurfacing the patella provided similar results when compared to routinely resurfacing. The study does emphasise however, that this conclusion depends greatly on femoral component design and operative diagnoses. This suggests that selective resurfacing with a so-called “patella friendly” femoral component in cases of tibio-femoral osteoarthritis, is a safe and effective strategy. Finally, registry data would support routine resurfacing with a 2.3 times higher relative risk of revision seen in the unresurfaced TKA. Regardless of which side of the debate one lies, the not so uncommon clinical scenario remains; what do we do with the painful TKA with an unresurfaced patella.

Precise and accurate diagnosis of the etiology of a painful TKA can be very difficult, and there is likely a strong bias towards early revision with secondary patellar resurfacing in the painful TKA with an unresurfaced TKA. At first glance, secondary resurfacing is associated with relatively poor outcomes. Correia, et al. reported that only half the patients underwent revision TKA with secondary resurfacing had resolution of their complaints. Similarly, only 53% of patients in another series were satisfied with the procedure and pain relief. The conclusions that can be drawn from these studies and others are that either routine patellar resurfacing should be performed in all TKA or, perhaps more importantly, we need to better understand the etiology of pain in an otherwise well-aligned, well-balanced, well-fixed TKA.

It is this author's contingency that the presence of an unresurfaced patella leads surgeons to reoperate earlier, without truly identifying the etiology of pain or dissatisfaction. This strong bias; basically there is something more that can be done, therefore we should do it, is the same bias that leads to early revision of partial knee arthroplasty. While very difficult, we as knee surgeons should not revise a partial knee or secondarily resurface a patella due to pain or dissatisfaction. Doing so, unfortunately, only works about half the time.

The diagnostic algorithm for evaluating the painful, uresurfaced TKA includes routinely ruling out infection with serum markers and an aspiration. Pre-arthroplasty radiographs should be obtained to confirm suitability and severity of disease for an arthroplasty. An intra-articular diagnostic injection with Marcaine +/− corticosteroid should provide significant pain relief. MARS MRI may be beneficial to evaluate edema within the patella. Lastly, operative implant stickers to confirm implant manufacturer and type are critical as some implants perform less favorably with unresurfaced patellae. To date, no studies of secondary resurfacing describe the results of this, or similar, algorithms for defining patellofemoral problems in the unresurfaced TKA and therefore it is still difficult to conclude that poor results are not simply due to our inherent bias towards early revision and secondary resurfacing of the unresurfaced patella.

Aim

We wonder what the results of two stage procedures were in terms of morbidity (amputation, dead) and infection recurrence. We also seek to identify risk factors for failure and see if the results of a second two stage surgery were not even worse.

Material and Methods

We retrospectively reviewed 140 prosthetic joint infection (PJI) treated with a two stage procedure. Patient data has been reviewed to determine which factors would be predictive for failure.

Purpose. Educational handouts designed for patients are promoted as a tool to educate, increase satisfaction, and potentially improve outcome. However, the value of these educational handouts as an adjunct to standard surgical care has not been formally assessed after ankle fracture. The purpose of this study was to compare standard post-operative care following surgically treated rotational ankle fracture to care supplemented with the use of adjunctive educational handouts. Method. Fifty-one patients who sustained a rotational ankle fracture requiring open reduction and internal fixation were randomized to receive either standard care (group S) for an ankle fracture, or to additionally receive the AAOS handout on ankle fractures and a handout describing appropriate mobilization exercises (group H). Standard care included follow up visits at 2, 6, and 12 weeks postoperatively in a busy orthopaedic fracture clinic, including brief instructions on mobilization exercises. A bulky plaster-reinforced dressing was used for immobilization for the first two weeks following surgery, followed by a removable boot. Range of motion exercises were encouraged after the first two weeks and weight bearing was encouraged six weeks after surgery. Surgeons and outcome assessors were blinded to treatment group. Patients completed functional outcome assessment (Olerud-Molander ankle score), objective measurement of ankle motion, and visual analog scale questions related to satisfaction at 6 and 12 weeks after surgery. Results. The groups were equivalent with respect to fracture type, and complication rate. Three patients, all in group S, were lost to follow-up. Group H patients had higher satisfaction scores at 3 months (9.2 vs 6.3; p < 0.01). Group H patients demonstrated improvements in Work/Activity ability at 6 weeks (p=0.01), but this benefit was not sustained at 3 months (p =0.24). No differences in motion or other functional outcome scores were noted. Conclusion. Educational handouts designed for patients can be helpful in providing patients with accessible information in the post-operative period. The use of an educational handout was a valuable tool to improve patient satisfaction, and may have the potential to improve outcome

Uncemented acetabular component fixation remains the gold standard for managing various defects in the revision hip setting. Multiple series have demonstrated over 90% ten-year survivorship of these constructs. Modern “enhanced” metals such as trabecular tantalum and titanium continue to perform well and are growing in popularity. So called “jumbo” cups, diameters >=62mm in females and >=66mm in males have demonstrated excellent survivorship. Good bony support with viable bone and stable initial fixation is necessary for long-term success. It is unknown how much remaining bone is necessary for reliable ingrowth with modern enhanced metals. The location of the remaining bone is probably more important than the absolute amount remaining. Occasionally, the uncemented cup must be augmented with metal augments or even a so-called “cup cage” construct. Even in these situations, the uncemented cup remains the workhorse of revision THA due to its ingrowth potential and excellent track record. Augments are commercially available in various shapes and sizes to assist in the management of cavitary, segmental and combined defects while restoring the desired cup position. Trials are available to ensure good approximation of the augment to remaining bone. The constructs are typically “unitised” to the cup via bone cement. Available data show excellent survivorship of augmented constructs for these challenging reconstructions.

Background

Total hip arthroplasty (THA) is one of the most successful surgical procedures ever performed. Nevertheless if procedure is performed by high or low volume surgeons; more than 50% of cups are still placed out of the safe zone, which is connected to lower survival rate of the prosthesis. The idea was to develop an imageless navigation system for safe and accurate positioning of the cup in THA procedures, without a need of any preoperative computer tomography (CT) or magnetic resonance imagining (MRI).

Methods

The validation of the system was approved by National Ethics Committee. The committee allowed the validation on 10 patients who all signed the agreement for participation in the study. Unselected patients undergoing THA were included. All patients had had performed preoperative x-rays of pelvis and hips for standard preoperative planning. Immediately before skin incision, anterior pelvic plane (APP) was defined with help of specially developed electromagnetic navigation system (Guiding Star, E-Hip module, Ekliptik d.o.o., Ljubljana, Slovenia) and specificaly designed hardware tool which is essential for accurate APP determination [Fig.1]. In all patients THAs were performed through direct lateral approach and all implanted components (Allofit S cup and Alloclassic stem, Zimmer Inc., Warsaw, Indiana, USA) were implanted with freehand technique according to preoperative plan. After placement of the cups their inclination and anteversion angles were determined with aforementioned navigation system [Fig. 2]. The day after surgery, low dose CT scans of pelvises of operated patients were performed and DICOM format files were up-loaded into EBS software (Ekliptik d.o.o., Ljubljana, Slovenia), a multipurpose application for perioperative planning, measuring and constructing where virtual copies of pelvises were generated. On virtual pelvises the position of the cups was measured by independent person [Fig.3]. Measurements were compared, statistically analysed and the deviation calculated with root mean square error (RMSE) method. Afterwards the average error (eaver) and standard deviation (σ) between intraoperatively determined and postoperatively measured angles were calculated.

CURRENT INDICATIONS

The ideal patient for unicompartmental arthroplasty has been described as an elderly sedentary individual with significant joint space loss isolated to either the medial or lateral compartment. Angular deformity should be no more than 5 or 10 degrees off a neutral mechanical axis. Ideal weight is below 180 pounds. Pre-operative flexion contracture should be less than 15 degrees. At surgery, the anterior cruciate ligament is ideally intact and there is no evidence of inflammatory synovitis. (Kozinn, Scott, 1989) Indications for the procedure have broadened today because of the availability of less invasive operative techniques and more rapid recovery with UKA. Because of its conservative nature, the procedure is being thought of as a conservative first arthroplasty in the middle-aged patient. Because of its less invasive nature with more rapid recovery and potentially less medical morbidity, it is being considered as the “last arthroplasty” in the octogenarian or older.

OUTCOMES OF UKA

Initial results reported for UKA in the 1970s were not as encouraging as they are today. This is most likely due to lessons that had yet to be learned about patient selection, surgical technique and prosthetic design. By the 1980s, reported results were improving with post-operative range of motion much higher than that reported for TKA. As longer follow-ups were reported, results were obtained that were competitive with those reported for TKA. Through the first post-operative decade, revision rates were being seen at approximately 1% failure per year or a 90% survivorship of the prosthesis at 10 years. More recently, however, some 10-year results have been reported that have survivorship well over 95% at 10 years. Modes of failure most often consist of problems with component wear or loosening or due to secondary degeneration of the opposite compartment. This latter complication is usually a late cause of failure, but can occur early if the alignment of the knee is over-corrected by the surgical technique.

Computer navigation has been introduced as an adjunct to Total Knee Arthroplasty (TKA) to assure precision positioning, accurate bone resection and optimal component alignment. Using Computer Assisted Navigation in TKA was a hotly debated issue in United States and elsewhere. Although Computer Navigation has progressed from the 1st generation to the current 3rd generation system, there are still no clearly tangible, apparent long term clinical benefits.

There is some evidence that using Computer Assisted Surgery may lower the incidence of malalignment of mechanical limb axis compared to conventional component placement methods, but it is unclear whether this marginal benefit will translate to concrete positive long term outcomes. AAHKS survey results indicated that the majority of Orthopedic Surgeons were not using computer navigated surgical techniques. The implementation of CAS met with so many hurdles and obstacles because its approach consumes more time and a long learning curve, which translates to added cost and complexity. It is also labor and equipment intensive but only increases accuracy in the “right” hands. Lack of popularity for CAS has induced the innovation of Patient Specific Jigs which has been proven to be extremely accurate, efficient with respect to time and allows surgeons to navigate the operation prior to the procedure.

Since CAS remains unpopular in the US, it would be even less popular in Asia for the obvious reasons of high cost, lack of experts to handle technical difficulties, lack of publicity, and the paucity of beneficial expert testimonies. The “Better, Cheaper, Faster” culture is fully ingrained in the minds of most Asian Arthroplasty surgeons and CAS would seem to only fulfill the “Better”, but not the “Cheaper and Faster” expectations in most hands.

Treatment for an infected Total Hip replacement (THR) remains controversial with two stage revision surgery traditionally recommended. We describe a series of one stage revisions performed in a District General Hospital to help inform other surgeons and help treatment decisions.

8 patients with a bacteriologically proven infection in their hip underwent single stage revision THR. Cemented Exeter prostheses were used with additional antibiotics added to the cement mixture prior to implantation.

Follow-up ranged from 6 to 36 months (average 16.6 months) and there were no re-infections. No radiological changes consistent with re-infection were noted throughout patient follow-up. One patient suffered a periprosthetic fracture (thought to be secondary to myeloma) 3 months post-surgery and underwent further revision surgery. Post-operative antibiotics were given for a minimum of 6 weeks with 2 patients having a 3 month supply after Microbiology advice.

Single stage revision THR surgery is a viable and useful option for treatment of infected THR's. Re-infection rates are low. Avoiding the traditional second stage surgery is beneficial to both patients and the NHS trust in terms of health and cost outcomes. We will continue to undertake single stage revisions in this trust and advocate its use by other surgeons.

Starting in 1977 a new cemented stem made of titanium alloy (with vanadium) was designed regarding some principle: rectangular shape, smooth surface covered with thin layer of titanium oxide, filling the medullar cavity. As a consequence: a thin layer of cement. It was designed with a collar. Initial Cementing technique used dough cement, vent tube and finger packing; then we applied cement retractor low viscosity cement and sometimes Harris Syringe. At the moment we went back to initial technique plus a cement retractor made of polyethylene. Many papers looked at long term follow up results depicting about 98 to 100 percent survivors at 10 years and 95 to 98% at 20 years (Hernigou, Hamadouche, Nizard, El Kaim).

Clinical as well as radiological results are available.

Radiological results depicted some radiolucent lines that appeared at the very long term. They could be related to friction between the stem and the cement. As advocated by Robin Ling, he called “French paradox” the fact that if a cemented prosthesis is smooth and fills the medullary cavity, long term excellent results could be expected.

This was the case with stainless steel Kerboull shape, the Ling design (Exeter)and the Ceraver design.

The majority of these stems were implanted with an all alumina bearing system. And in some occasion, when revision had to be performed, the stem was left in place (108 cases over 132 revisions)

Our experience over more than 5000 stems implanted is outstanding (see figure 1: aspect after 30 years).

Discussion other experience with cemented titanium stem were bad (Sarmiento, Fare). We suspect that this was related either to the small size of this flexible material, or to the roughness of its surface.

If one uses titanium cemented stem it must be large enough and extra smooth.

Purpose

To review the outcomes of patients undergoing manipulation under anaesthetic (MUA) after primary total knee arthroplasty (TKA) and predict those that may require such a procedure.

Methods

Prospective analysis of patients who required MUA post TKA performed by two surgeons using the same prosthesis from 2003 to 2008. Compared to a control group of primary TKA matched for age, gender and surgeon. All patients in both groups had pre- and post-operative measurements of range of movement. Risk factors were identified including warfarin and statin use, diabetes and body mass index.

Introduction

The aim of the study was to whether the bone grafting techniques used affected the long term stability of the acetabular implant.

Methods

41 patients treated with a cemented total hip replacement with pre-operative protrusio or central acetabular defects at surgery were identified. The severity of initial protrusio was determined on plain AP pelvis radiographs by measuring the distance of the medial acetabular wall from the ilio-ischial line. The post-operative and last follow-up x-rays were reviewed, the thickness of the medial wall and the centre-edge angle of the cup was measured.

A high volume of trauma and limited resources means that traditional methods of bone reconstruction are not feasible in parts of Africa. We present the management and outcomes of using Masquelet's concept, of an induced membrane and secondary morcellised cancellous bone grafting, in patients with severe lower limb trauma.

Eleven patients were treated in an orthopaedic department in rural southern Africa between 2011 and 2012. This is a subgroup that is part of a larger study of open fractures that received ethical approval.

All patients were male, with ten aged between 20 and 35 and one aged 70. Two were HIV positive. There were three open femur and eight open tibia fractures. Three required fasciocutaneous flaps and one required a muscle flap to achieve adequate soft tissue coverage. Eight cases were performed as the primary treatment and three were to treat septic non-unions. Bone defects ranged from 4 to 10 cm. Definitive bony stabilisation was maintained by mono-lateral external fixator in three patients. In other cases this was converted to a circular frame or internal fixation.

The results have been mixed. In three patients bone grafting was delayed due to wound or pin site problems. In one case the bone graft was lost due to infection but repeating the procedure produced a good result. Time to bony union in each case is difficult to quantify. However, there is clear evidence of new bone forming in most cases. Four patients are weight bearing with external fixation removed, as are five patients with internal fixation. In a few cases bony union appears to be taking significantly longer, if at all.

Masquelet technique is a welcome addition to the options available in bone reconstruction. However, time to achieve bony union is unpredictable. Refinement of the technique for use in the developing world is needed.

The requirement for the peer support groups were born out of concern for the psychological wellbeing of the paediatric patients and to assess if this would improve their wellbeing during their treatment. Groupwork is a method of Social Work which is recognised as a powerful tool to allow people meet their need for belonging while also creating the forum for group members to empower one another. Social Work meet with all paediatric patients attending the limb reconstruction service in the hospital. The focus of the Medical Social Worker (MSW) is to provide practical and emotional support to the patient and their parent/guardian regarding coping with the frame. Some of the challenges identified through this direct work include patient's struggling with the appearance of the frame and allowing peers to see the frame. The peer support group aims to offer its attendees the opportunities to engage with fellow paediatric patients in the same position. It allowed them to visually identify with one another. We wanted to create a safe space to discuss the emotional impact of treatment and the frames. It normalises the common problems paediatric patients face during treatment. We assisted our participants to identify new coping techniques and actions they can take to make their journey through limb reconstruction treatment more manageable. Finally, we aimed to offer the parents space to similarly seek peer support with regard to caring for a child in treatment. All paediatric patients were under the care of the Paediatric Orthopaedic Consultant and were actively engaging with the limb reconstruction multi-disciplinary team (MDT). The patient selection was completed by the MDT; based on age, required to be in active treatment, or their frames were removed within one month prior to the group's commencement. Qualitative data was collected through written questionnaires and reflection from participants in MSW sessions. We also used observational data from direct verbal feedback from the MDT. In the first group, parents gave feedback due to participants age and completed written feedback forms. For our second group, initial feedback was collated from the participants after the first session to get an understanding of group expectations. Upon completion, we collected data from both the participants and the parents. Qualitative and scaling questions gathered feedback on their experience of participating in the group. We held two peer support groups in 2022:One group for patients aged between 3–6 years in January 2022 across two sessions, which was attended by four patients. The second group for young teenage patients aged between 11–15 years in April 2022 across four sessions, which was attended by five patients. The written feedback received from group one focused on eliciting the participant's experience of the groupwork. 100% of participants identified the shared experience as the main benefit of the groupwork. 100% of participants agreed they would attend a peer support group again, and no participant had suggestions for improvement to the group. Feedback did indicate that group work at the beginning of treatment could be more beneficial. In relation to the second group, 60% of the paediatric patients and their parents returned the questionnaires. All of the parent's feedback identified that it was beneficial for their child to meet peers in a similar situation. They agreed that it was beneficial to meet other parents, so they could get support and advice from one another. On a scale between 1 and 5, 5 being the highest score, the participants scored high on the group work meeting their expectations, enjoyment of the sessions, and the group work was a beneficial aspect of their treatment. All respondents would strongly recommend groupwork to other paediatric patients attending for limb reconstruction treatment. Overall, the MDT limb reconstruction team, found the peer support group work of great benefit to the participants and their parents. The MSW team identified that during a period on the limb reconstruction team, when a high number of patients were in active treatment, the workload of the MSW also increased reflecting this activity. Common issues and concerns were raised directly to MSW (particularly from group two) regarding numerous difficulties they experienced trying to cope with the frame. The group work facilitators created a space where the participants could get peer support, share issues caused by the frame, hear directly from others, and that they too experience similar feelings or issues. Collectively, they identified ways of coping and promoting their own wellbeing while in treatment. The participants in group two, subsequently created a group on social media, to be able to continue their newly formed friendships and to continue to update one another on their treatment journeys. The participants self-requested another group in the future. This was facilitated in November 2023, the facilitators sought more feedback from all participants and their parents after this session. These findings will contribute towards the analysis for the presentation. Peer support groupwork was presented at the hospital's foundation day and has been well received by senior management in the hospital, as a positive addition to the limb reconstruction service. The focus of the MDT in 2024, is to further develop and facilitate more peer support groups for our paediatric patients
