Objective: Diagnostic delay is well recognised in soft tissue sarcoma (STS). The aim of this paper is to assess whether symptom duration/time to diagnosis, has any impact on patient survival and also if patient and tumour-related factors are related to the duration of symptoms prior to presentation. Method: We performed a retrospective analysis of prospectively collected data for all patients diagnosed or treated with STS at our centre over a 20-year period. Information regard¬ing when the patients first experienced symptoms was entered into a local oncology database at their first consultant-outpatient appointment. Symptom duration was defined as time in weeks from first symptoms experienced by the patient to the time of diagnosis. Data analysis was performed using StatView and R. Risk factors were assessed by Kaplan-Meier analysis and the Cox proportional hazards model. Stat¬istical significance was determined using 95% confidence intervals where appropriate. Students t-test was used to compare categorical data. Results: The study population comprised 1508 patients. 159 had metastatic disease at diagnosis and overall 5-year survival in this group was 14%. In view of this poor prognosis these patients were excluded from further analyses. In the remaining 1349 patients overall 5-year survival was 60%. Mean symptom duration within our study was 70.2 weeks. A Cox Proportional hazards model showed that duration of symptoms had a significant impact on survival (p=0.0037) with each additional week of symptoms reducing the monthly hazard rate by 0.2%. Patient and tumour-related factors that were significantly associated with longer symptom durations were low grade, subcutaneous tumours, and those patients with either epitheliod or synovial sarcomas. Symptom duration was not associated with tumour size or patient age/gender. Conclusion: Patients presenting with long symptom durations/diagnostic delay, tend to have low grade disease and a more favourable outcome than patients who experience short symp¬tom durations

Aim

The purpose of this study is to report the overall infection control rate and prognostic factors associated with acute, hematogenous and chronic PJIs treated with DAIR.

Aims. We hypothesised that the synovial white blood cell (WBC) count in patients with a late periprosthetic joint infection (PJI) of the hip would depend on the duration of a patient’s symptoms, and that the optimal diagnostic threshold would also depend on this period of time. Patients and Methods. The synovial WBC count and percentage of polymorphonuclear cells (%PMN), and the serum CRP and ESR levels obtained > six weeks after primary THA were compared between 50 infected and 88 non-infected THAs, and in patients with symptoms for more than or less than two weeks. Diagnostic thresholds for the synovial WBC count were calculated using area under the curve calculation. Results. The synovial WBC count was significantly higher in patients with symptoms for ≤ two weeks compared with those with symptoms for > two weeks (p = 0.03). The optimal threshold for diagnosing PJI for the synovial WBC count was 5750 cells/µL (sensitivity 94; specificity 100; PPV 100%; NPV 89%; AUC 99%) and 1556 cells/µL (sensitivity 91; specificity 94; PPV 87% and NPV 97%; AUC 95%), respectively. The thresholds for the cut-offs based on duration of symptoms improved the diagnostic performance of this test. Conclusion. This study shows that the diagnostic thresholds for synovial fluid analysis in late periprosthetic infection following THA may depend on duration of symptoms.

Aims. Deprivation underpins many societal and health inequalities. COVID-19 has exacerbated these disparities, with access to planned care falling greatest in the most deprived areas of the UK during 2020. This study aimed to identify the impact of deprivation on patients on growing waiting lists for planned care. Methods. Questionnaires were sent to orthopaedic waiting list patients at the start of the UK’s first COVID-19 lockdown to capture key quantitative and qualitative aspects of patients’ health. A total of 888 respondents were divided into quintiles, with sampling stratified based on the Index of Multiple Deprivation (IMD); level 1 represented the ‘most deprived’ cohort and level 5 the ‘least deprived’. Results. The least deprived cohort were older (mean 65.95 years (SD 13.33)) than the most deprived (mean 59.48 years (SD 13.85)). Mean symptom duration was lower in the least deprived areas (68.59 months (SD 112.26)) compared to the most deprived (85.85 months (SD 122.50)). Mean pain visual analogue scores (VAS) were poorer in the most compared to the least deprived cohort (7.11 (SD 2.01) vs 5.99 (SD 2.57)), with mean mood scores also poorer (6.06 (SD 2.65) vs 4.71 (SD 2.78)). The most deprived areas exhibited lower mean quality of life (QoL) scores than the least (0.37 (SD 0.30) vs 0.53 (SD 0.31)). QoL findings correlated with health VAS and Generalized Anxiety Disorder 2-item (GAD2) scores, with the most deprived areas experiencing poorer health (health VAS 50.82 (SD 26.42) vs 57.29 (SD 24.19); GAD2: 2.94 (SD 2.35) vs 1.88 (SD 2.07)). Least-deprived patients had the highest self-reported activity levels and lowest sedentary cohort, with the converse true for patients from the most deprived areas. Conclusion. The most deprived patients experience poorer physical and mental health, with this most adversely impacted by lengthy waiting list delays. Interventions to address inequalities should focus on prioritizing the most deprived. Cite this article: Bone Jt Open 2022;3(10):777–785

Interstitial supraspinatus tears can cause persistent subacromial impingement symptoms despite non operative treatment. Autologous tendon cell injection (ATI) is a non-surgical treatment for tendinopathies and tear. We report a randomised controlled study of ATI compared to corticosteroid injection (CS) as treatment for interstitial supraspinatus tears and tendinopathy. Inclusion criteria were patients with symptom duration > 6 months, MRI confirmed intrasubstance supraspinatus tear, and prior treatment with physiotherapy and ≥ one CS or PRP injection. Participants were randomised to receive ATI to the interstitial tear or corticosteroid injection to the subacromial bursa in a 2:1 ratio, under ultrasound guidance. Assessments of pain (VAS) and function (ASES) were performed at baseline, and 1, 3, 6 and 12 months post treatment. 30 participants (19 randomised to ATI) with a mean age of 50.5 years (10 females) and a mean duration of symptoms of 23.5 months. Baseline VAS pain and ASES scores were comparable between groups. While mean VAS pain scores improved in both groups at 3 months after treatment, pain scores were superior with ATI at 6 months (p=0.01). Mean ASES scores in the ATI group were superior to the CS group at 3 months (p=0.026) and 6 months (p=0.012). Seven participants in the CS group withdrew prior to 12 months due to lack of improvement. At 12 months, mean VAS pain in the ATI group was 1.6 ± 1.3. The improvements in mean ASES scores in the ATI group at 6 and 12 months were greater than the MCID (12.0 points). At 12 months, 95% of ATI participants had an ASES score > the PASS (patient acceptable symptom state). This is the first level one study using ATI to treat interstitial supraspinatus tear. ATI results in a significant reduction in pain and improvement in shoulder function

Aim. Debridement, antibiotics and implant retention (DAIR) are considered as an optimal curative treatment option for prosthetic joint infection (PJI) when the biofilm is still immature and radical debridement is achievable. There are two main groups of patients suitable for DAIR. Those with an early acute PJI and patients with acute hematogenous PJI. However, there is also a third group of early PJI resulting from a wound healing problem or leaking hematoma. These may be either high or low grade depending on the microorganisms that infected the artificial joint “per continuitatem”. Methods. We retrospectively analysed 100 successive DAIR procedures on prosthetic hip and knee joints performed between January 2010 and January 2022, from total of 21000 primary arthroplasties implanted within the same time period. We only included PJI in primary total replacements with no previous surgeries on the affected joint. Patients data (demographics, biochemical, microbiological, histopathological results, and outcomes) were collected from hospital bone and joint infection registry. The aim of surgery was radical debridement and the mobile parts exchange. The standardized antibiotic regime based on antibiofilm antibiotics. Results. The mean age of patients was 70 years (60% women, 43 hips, 57 knees) with a mean follow-up of 3 years. 45 cases were early acute or related to wound healing problems, 55 were hematogenous PJI. 25 patients received preoperative antibiotics. 6 of these were culture negative. The mean symptom duration was 7 days. Mean age of the prosthesis was 30 days for early, and 1064 days for the hematogenous group. Conclusions. In our cohort the success rate of DAIR is 94% which indicates that the protocol is highly successful in PJI with short-lasting symptoms and “debridable” joints. Antibiotic protocol violation and duration of symptoms may have a role in failures

Prolonged length of stay (LOS) is a significant contributor to the variation in surgical health care costs and resource utilization after elective spine surgery. The primary goal of this study was to identify patient, surgical and institutional variables that influence LOS. The secondary objective is to examine variability in institutional practices among participating centers. This is a retrospective study of a prospectively multicentric followed cohort of patients enrolled in the CSORN between January 2015 and October 2020. A logistic regression model and bootstrapping method was used. A survey was sent to participating centers to assessed institutional level interventions in place to decrease LOS. Centers with LOS shorter than the median were compared to centers with LOS longer than the median. A total of 3734 patients were included (979 discectomies, 1102 laminectomies, 1653 fusions). The median LOS for discectomy, laminectomy and fusion were respectively 0.0 day (IQR 1.0), 1.0 day (IQR 2.0) and 4.0 days (IQR 2.0). Laminectomy group had the largest variability (SD=4.4, Range 0-133 days). For discectomy, predictors of LOS longer than 0 days were having less leg pain, higher ODI, symptoms duration over 2 years, open procedure, and AE (p< 0.05). Predictors of longer LOS than median of 1 day for laminectomy were increasing age, living alone, higher ODI, open procedures, longer operative time, and AEs (p< 0.05). For posterior instrumented fusion, predictors of longer LOS than median of 4 days were older age, living alone, more comorbidities, less back pain, higher ODI, using narcotics, longer operative time, open procedures, and AEs (p< 0.05). Ten centers (53%) had either ERAS or a standardized protocol aimed at reducing LOS. In this study stratifying individual patient and institutional level factors across Canada, several independent predictors were identified to enhance the understanding of LOS variability in common elective lumbar spine surgery. The current study provides an updated detailed analysis of the ongoing Canadian efforts in the implementation of multimodal ERAS care pathways. Future studies should explore multivariate analysis in institutional factors and the influence of preoperative patient education on LOS

Background. Sciatica is common and associated with significant impacts for the individual, health care and society. The SCOPiC randomised controlled trial (RCT) is investigating whether stratified primary care for sciatica is more effective and cost-effective than usual, non-stratified primary care. Stratified care involves subgrouping patients to one of three groups based on a combination of prognostic and clinical indicators. Patients in one of these groups are ‘fast-tracked’ with an MRI scan to spinal specialist opinion. Our aim was to understand the perspectives of clinicians on the acceptability of this ‘fast-track’ pathway. Methods. Qualitative, semi-structured interviews were conducted with general practitioners, spinal specialist physiotherapists and spinal surgeons (n=20 in total). Interviews were fully transcribed, and data were analysed using the constant comparison method. Results. Across all groups, clinicians identified potential added value in ‘fast-tracking’ some sciatica patients in terms of patient reassurance based on MRI scan findings. Whilst spinal physiotherapists felt that most ‘fast track’ patients were appropriate, some spinal physiotherapists and GPs had concerns that patients with symptom durations of less than 6 weeks might be inappropriately fast-tracked since their symptoms may still resolve without the need for invasive treatments. Spinal surgeons felt it was acceptable for patients with short symptom durations to be ‘fast-tracked’, but to provide early reassurance rather than direct treatment. Conclusion. Whilst clinicians saw added value in a group of sciatica patients being ‘fast-tracked’ to specialist opinion, there was some reservation about moving away from the usual stepped care, ‘wait and see’ approach for patients with short symptom duration.

Aim. Sepsis is a life-threatening complication of periprosthetic joint infections (PJI) that requires early and effective therapy. This study aims to investigate the epidemiology, associated risk factors, and outcome of sepsis in the context of periprosthetic joint infections (PJI). Method. This single-center retrospective cohort study included patients treated for PJI from 2017 to 2020. Patients were classified based on the criteria of the European Bone and Joint Infection Society. The presence of sepsis was determined using the SOFA score and SIRS criteria. The cohort with PJI and sepsis (sepsis) was compared to patients with PJI without sepsis (non-sepsis). Risk factors considered were patient characteristics, affected joints, surgical therapy, microbiological findings, preexisting medical conditions, clinical symptoms, and symptom duration. Outcome parameters were mortality, length of hospital stay, and length of stay in the intensive care unit. Results. A total of 109 patients with PJI were identified, of whom 45 patients (41.3%) met the criteria for sepsis. Patients with sepsis had more severe preexisting diseases compared with the non-sepsis cohort (Charlson Comorbidity Index 3.8 vs. 2.8; p≤0.001). An increased odds ratio (OR) for a septic course was found for the comorbidities pneumonia (8.2; p=0.001), myocardial infarction (2.0; p=0.02), atrial fibrillation (3.3; p=0.01), diabetes mellitus (1.2; p=0.04), endocarditis (5.5; p=0.01), and renal disease (2.0; p≤0.001). Infection with Staphylococcus aureus (sepsis 20 vs. non-sepsis 10; p=0.002), Streptococcus dysgalactiae (sepsis 7 vs. non-sepsis 2; p=0.002) and Candida albicans (sepsis 5 vs. non-sepsis 0; p=0.01) were more prevalent in patients with sepsis. In the sepsis cohort, further infectious foci were present in addition to PJI in 57.8% of patients, compared to 18.8% in the non-sepsis cohort. The presence of sepsis was associated with a longer hospital stay (sepsis 68 days vs. non-sepsis 38 days; p=0.001) and longer intensive care unit stay (sepsis 12 days vs. non-sepsis 2 days; p=0.001). In-hospital mortality was ten times higher in the sepsis cohort compared to non-septic patients (sepsis 11/42 vs. non-sepsis 2/64; OR 10.3; p=0.01). Conclusions. In a relevant proportion of patients, PJI can lead to a septic course of disease associated with increased mortality. Particularly in patients with preexisting diseases, increased attention is required, and comprehensive screening for other foci of infection seems mandatory. In addition to highly virulent pathogens such as staphylococci and streptococci, fungal infections should be considered as causative pathogens in septic patients with PJI

Objective. Sarcomas are a rare group of tumours, which pose numerous problems regarding correct diagnosis and appropriate management. This study aimed to examine whether symptom duration and tumour size at diagnosis have changed over time, using size and symptom duration as methods of comparison. Methods. All patients diagnosed with sarcoma were identified retrospectively from a prospective database from 1963 to 2005. Demographic data concerning age at diagnosis, sex and diagnosis were recorded. Data were also collected on duration of symptoms and size of tumour at diagnosis. Symptom duration is defined as the length of time the patient was experiencing symptoms for until the date of diagnosis. Changes in size and symptom duration over time were compared by grouping date of diagnosis into time periods and comparing them against each other using non-parametric statistical analysis. Results. 4560 met our inclusion and exclusion criteria, with 2492 Bone Sarcomas (BS) and 2068 Soft Tissue Sarcomas (STS). Overall analysis of both BS and STS showed that size at diagnosis has decreased and symptom duration has increased. Analysis of STS showed that size has decreased over time, particularly following the introduction of referral guidelines in 1999 (median size pre 99 = 10cm, post = 8cm, Mann-Whitney-U test p=0.000 to 3 sig. fig.), but symptom duration has remained unaltered over time. Duration of symptoms reported for BS has significantly increased over time; however, size at diagnosis has remained unchanged over time. Conclusions. It appears from this study that STS are being diagnosed more quickly and that this is most likely due to the introduction of specific STS guidelines in 1999. This result is particularly heartening, and should encourage further promotion of such guidelines. Awareness of BS still appears to be low as size at diagnosis remains unchanged over time

Objectives. To assess the affects of a delay in diagnosis on the survival rates of Bone Sarcoma (BS) using size and symptom duration as measures of delay. Methods. All patients diagnosed with a Primary BS from 1970 to 2005 were included. Demographic data concerning age, sex, diagnosis and tumour site were recorded. The data were collected retrospectively from a prospective database, with 2573 patients included. Symptom duration is defined as the length of time the patient was experiencing symptoms for until the date of diagnosis. Survival analysis was performed using Kaplan-Meier curves and Cox Regression was carried out to identify variables affecting outcome. Results. 2489 patients with Primary BS that matched out inclusion and exclusion criteria were identified. Osteosarcoma (40.4%), Chondrosarcoma (20.6%) and Ewing's Sarcoma (17.6%) were the most common diagnoses, with a median size of 10cm at presentation. Overall 5 year survival was 61.2%, extremity sited tumours carried a statistically significant better prognosis compared to axial tumours (5yr survival 63.2% vs. 53.3%) and patients with axial tumours had significantly longer symptom duration (Mann-Whitney U test p = 0.000 31 and 12 weeks). Overall analysis of all BS diagnoses showed lengthier duration of symptoms was associated with a better outcome (Hazard Ratio = 0.998, p = 0.000), which suggests that 1 extra week of symptoms confers an increased survival of 0.2%. Larger tumour size was associated with a poorer survival rate (p=0.000 to 3 sig. fig, Hazard Ratio 1.059 respectively) which suggests that for every 1cm increase in size there is a decreased survival of 5.9%. Conclusions. Although many factors have been associated with survival, the limited literature concerning symptom interval and outcome is varied. This large study has shown that regardless of diagnosis, overall, shorter symptom duration and a large tumour size are associated with a poorer prognosis

Introduction. Studies have compared outcomes of first metatarsophalangeal joint (MTPJ1) implant hemiarthroplasty and arthrodesis, but there is a paucity of data on the influence of patient factors on outcomes. We evaluated data from a prospective, RCT of MTPJ1 implant hemiarthroplasty (Cartiva) and arthrodesis to determine the association between patient factors and clinical outcomes. Methods. Patients ≥18 years with Coughlin hallux rigidus grade 2, 3, or 4 were treated with implant MTPJ1 hemiarthroplasty or arthrodesis. Pain VAS, Foot and Ankle Ability Measure (FAAM) Sports and ADL, and SF-36 PF scores were obtained preoperatively, and at 2, 6, 12, 24, 52 and 104 weeks postoperatively. Final outcomes, MTPJ1 active peak dorsiflexion, secondary procedures, radiographs and safety parameters were evaluated for 129 implant hemiarthroplasties and 47 arthrodeses. Composite primary endpoint criteria for clinical success included pain reduction ≥30%, maintenance/improvement in function, and no radiographic complications or secondary surgical intervention at 24 months. Predictor variables included: grade; gender; age; BMI; symptom duration; prior MTPJ1 surgery; preoperative hallux valgus angle, ROM, and pain. Two-sided Fisher's Exact test was used (p< 0.05). Results. Patient demographics and baseline outcome measures were similar. Success rates between implant MTPJ1 hemiarthroplasty and arthrodesis were similar when stratified by hallux rigidus grade, gender, age, BMI, symptom duration, prior MTPJ1 surgery status, and preoperative VAS pain, hallux valgus and ROM (p0.05). Conclusion. Synthetic cartilage implant hemiarthroplasty (Cartiva) is an appropriate treatment for patients with hallux rigidus grade 2, 3 or 4 and is a reasonable choice in hallux rigidus in patients with < 20 degrees HVA, with a high degree of preoperative stiffness, irrespective of gender, age, BMI, hallux rigidus grade, preoperative pain, or duration of symptoms, in contrast to what might have been expected

Purposes and Background. Musculoskeletal disorders are leading causes of work disability. Our purpose was to develop a predictive model in a cohort from 2012 and validate the model in 2016 data. Methods and Results. Prospectively collected data was used to identify inception cohorts in 2012 (n=1652) and 2016 (n=199). Data from back pain claimants receiving treatment in physiotherapy clinics and the Ontario workers' compensation database were linked. Patients were followed for 1 year. Variables from a back pain questionnaire and clinical, demographic and administrative factors were assessed for predictive value. The outcome was cumulative number of calendar days receiving wage-replacement benefits. Cox regression revealed 8 significant predictors of shorter time on benefits in the 2012 cohort: early intervention (HR=1.51), symptom duration < 31 days (HR=0.88), not in construction industry (HR=1.89), high Low Back Outcome Score (HR=1.03), younger age (HR=0.99), higher benefit rate (HR=1.00), intermittent pain (HR=1.15), no sleep disturbance (HR=1.15). The 2012 model c-statistic was 0.73 with a calibration slope of 0.90 (SE=0.19, p=0.61) in the 2016 data, meaning not significantly different. The c-statistic in the 2016 data was 0.69. Median duration on benefits of those with a high risk score was 129 days in 2012 and 45 days in 2016. Conclusion. The 2012 model had a good fit and calibrated well in the 2016 data. Changes in case management by the WSIB might have resulted in significant differences between the 2012 and 2106 cohort. The difference in duration on benefits could affect treatment decision making in future. Conflicts of interest: IWH is funded by the Ministry of Labour in Ontario.

Introduction and Aims: To determine differences in rotator cuff tissue with duration of symptoms and tear size. Method: Rotator cuff tissue was obtained at debridement from 44 patients undergoing surgical repair. Pathological assessment was performed on H& E sections. Features evaluated included inflammation, micro-calcification, tendolipomatosis and fibroblast hypocellularity. Matrix quality and endothelial cell proliferation were examined. Patient details – age, tear size and duration of symptoms were extracted from notes. Results: Matrix quality was significantly worse in small tears (p=0.028), particularly the extent of mucoid degeneration in the debrided tissue (p=0.017). Presence of a healthy cut margin was more likely in a large tear (10/14). Poor matrix was significantly associated with symptom duration > 15months (p=0.006) especially microcalicification (p=0.019) and mucoid degeneration (p=0.047). Endothelial cell proliferation was significantly more apparent in patients with longer duration of symptoms: previous vascular tufting (p=0.001) and ongoing vascular proliferation (p=0.019). Of 27 patients > 15months symptoms, vascular proliferation was strongly correlated with split collagen fibres (p< 0.018) and mucoid degeneration (p< 0.018) but not microcalcification. Tendolipomatosis was strongly correlated with ongoing vascular proliferation (p< 0.0006). Conclusion: Successful surgical repair is only achieved in 30% patients with rotator cuff tears. Improvements in this success rate will be essential in order to maintain the independent lifestyle of an elderly population. Although the tissue examined here is debrided, and hence worst case tissue, several time-dependent processes are ongoing, degeneration, repair and remodelling. Matrix quality is deteriorating, however, this maybe supportive of the angiogenic component of repair. Remodelling may be seen in the increased probability of a healthy cut margin from patients with longer symptom duration

The August 2012 Oncology Roundup. 360. looks at: prolonged symptom duration; peri-operative mortality and above-knee amputation; giant cell tumour of the spine; surgical resection for Ewing’s sarcoma; intercalary allograft reconstruction of the femur for tumour defects; and an induced membrane technique for large bone defects

Aims

To identify the incidence and risk factors for five-year same-site recurrent disc herniation (sRDH) after primary single-level lumbar discectomy. Secondary outcome was the incidence and risk factors for five-year sRDH reoperation.

Background. Criticisms about overuse of MRI in low back pain are well documented. Yet, with the exception of suspicion of serious pathology, little is known about factors that influence clinicians' preference for MRI. We investigated the factors associated with physiotherapists' preference for MRI for patients consulting with benign low back and leg pain (LBLP) including sciatica. Methods. Data were collected from 607 primary care patients consulting with LBLP and assessed by 7 physiotherapists, in the ATLAS cohort study. Following clinical assessment, physiotherapists documented whether he/she wanted the patient to have an MRI. Factors potentially associated with clinicians' preference for imaging were selected a priori, from patient characteristics and clinical assessment findings. A mixed-effect logistic regression model examined the associations between these factors and physiotherapists' preference for MRI. Results. Physiotherapists expressed a preference for MRI in 32% (196/607) of patients, of whom 22 did not have a clinical diagnosis of sciatica (radiculopathy). Factors associated with preference for MRI included; clinical diagnosis of sciatica (OR 4.23: 95% CI 2.29,7.81), greater than 3 months pain duration (OR 2.61: 95% CI 1.58,4.30), high pain intensity (OR 1.24: 95%CI 1.11,1.37), patient's low expectation of improvement (OR 2.40: 95% 1.50,3.83), physiotherapist's confidence in the diagnosis (OR 1.19: 95% CI 1.07,1.33) with greater confidence associated with higher probability of preference for MRI. Conclusion. A clinical diagnosis of sciatica and longer symptom duration were most strongly associated with physiotherapists' preference for MRI. Given current best practice guidelines, these appear to be justifiable reasons for wanting patients to have an MRI. Conflicts of interest: None. Funding.

Aims

The epiphyseal approach to a chondroblastoma of the intercondylar notch of a child’s distal femur does not provide adequate exposure, thereby necessitating the removal of a substantial amount of unaffected bone to expose the lesion. In this study, we compared the functional outcomes, local recurrence, and surgical complications of treating a chondroblastoma of the distal femoral epiphysis by either an intercondylar or an epiphyseal approach.

Aims

The presence of facet tropism has been correlated with an elevated susceptibility to lumbar disc pathology. Our objective was to evaluate the impact of facet tropism on chronic lumbosacral discogenic pain through the analysis of clinical data and finite element modelling (FEM).

Aims

The purpose of this study was to evaluate the mid-term outcomes of autologous matrix-induced chondrogenesis (AMIC) for the treatment of larger cartilage lesions and deformity correction in hips suffering from symptomatic femoroacetabular impingement (FAI).
