Introduction. Patellar tendinopathy is a highly prevalent clinical diagnosis supported by ultrasound changes. Numerous interventions are targeted at improving both symptoms and structure of dysfunctional tendons, however little is known of the diagnostic value in a changing ultrasound profile whilst patient reported outcome measures determine recovery. The aim of this study was to assess if change in ultrasound measure is congruent with change in Victorian Institute of Sport Assessment – Patella (VISA-P) score and therefore indicates the use of using ultrasound to assess patellar tendinopathy during symptom change. Method. Four databases (PubMed, Web of Science, Embase, Cinahl) were search in January 2014. Studies selected contained ultrasound and VISA-P scores from ≥ 2 type points. All included studies were quality assessed depending on type and available data underwent meta-analysis. Result. 10 papers of varying study type, of limited to high quality, were synthesised. Meta-analysis indicated that change in ultrasound measure was not congruent with change in VISA-P score. Conclusion. The variation in study quality, along with significant heterogeneity of ultrasound measure outcomes and reporting may influence the congruency of the data, but the association between gradual structure change and varying vascularity with pain or function is questionable throughout tendinopathy literature

Meniscal tears are the most common injury in the knee, affecting 66/100,000 people/year. Surgical treatment includes arthroscopic meniscectomy or meniscal repair. Little is known regarding medium-term outcomes following these procedures in isolated meniscal tears. This study aims to quantitatively evaluate patients with meniscal tears, and those who have undergone meniscectomy and meniscal repair using validated patient reported outcome measures (PROMs), further exploring factors which affect surgical outcomes. This observational study screened 334 patients who underwent arthroscopic surgery at South Tyneside Hospital since August 2013. 134 patients with isolated meniscal tears were invited to complete postal PROMs. A combination of patient notes and radiological imaging was used to collect information of interest including age, gender, knee-laterality, injured meniscus, tear pattern, procedure performed, complications, and associated injuries. A total of 115 patients (pre-operative patients with current meniscal tear (n=36), meniscectomy (n=63), meniscal repair (n=16)) were included in the analysis with 96% successful PROM completion. Both meniscectomy and meniscal repairs (mean 55-months follow-up) showed better outcomes than pre-operative patients with meniscal tears. Meniscal repairs demonstrated superior outcomes across all PROMs when compared to meniscectomy, with a greater mean overall KOOS score of 17.2 (p=0.009). Factors including higher pre-operative Kellgren-Lawrence Grade, pre-operative articular cartilage lesions and bilateral meniscectomies were shown to negatively influence outcomes. Both meniscectomy and meniscal repair maintain clinical benefit at mean 55-months follow-up, affirming their use for treatment of meniscal tears. When feasible, meniscal repair should be performed preferentially over meniscectomy in isolated meniscal tears. Identified predictive factors allow adequate treatment stratification in specific patient groups

Dual mobility hip arthroplasty utilizes a freely rotating polyethylene liner to protect against dislocation. As liner motion has not been confirmed in vivo, we investigated the liner kinematics in vivo using dynamic radiostereometry. 16 patients with Anatomical Dual Mobility acetabular components were included. Markers were implanted in the liners using a drill guide. Static RSA recordings and patient reported outcome measures were obtained at post-op and 1-year follow-up. Dynamic RSA recordings were obtained at 1-year follow-up during a passive hip movement: abduction/external rotation, adduction/internal rotation (modified FABER-FADIR), to end-range and at 45° hip flexion. Liner- and neck movements were described as anteversion, inclination and rotation. Liner movement during modified FABER-FADIR was detected in 12 of 16 patients. Median (range) absolute liner movements were: anteversion 10° (5–20), inclination 6° (2–12), and rotation 11° (5–48) relative to the cup. Median absolute changes in the resulting liner/neck angle (small articulation) was 28° (12–46) and liner/cup angle (larger articulation) was 6° (4–21). Static RSA showed changes in median (range) liner anteversion from 7° (-12–23) postoperatively to 10° (-3–16) at 1-year follow-up and inclination from 42 (35–66) postoperatively to 59 (46–80) at 1-year follow-up. Liner/neck contact was associated with high initial liner anteversion (p=0.01). The polyethylene liner moves over time. One year after surgery the liner can move with or without liner/neck contact. The majority of movement is in the smaller articulation between head and liner

The aim of this study was to perform a systematic review of the literature on Gustilo-Anderson (GA) type IIIB open tibial shaft (AO-42) injuries to determine the consistency of reporting in the literature. A search of PubMed, EMBASE and Cochrane Central Register of Controlled Trials was performed to identify relevant studies published from January 2000 to January 2021 using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The study was registered using the PROSPERO International prospective register of systematic reviews. Patient/injury demographics, management and outcome reporting were recorded. There were 32 studies that met the inclusion criteria with a total of 1,947 patients (70.3% male, 29.7% female). There were 6 studies (18.8%) studies that reported on comorbidities and smoking, with mechanism of injury reported in 22 (68.8%). No studies reported on all operative criteria included, with only three studies (9.4%) reporting for time to antibiotics, 14 studies (43.8%) for time from injury to debridement and nine studies (28.1%) for time to definitive fixation. All studies reported on the rate of deep infection, with a high proportion documenting union rate (26/32, 81.3%). However, only two studies reported on mortality or on other post-operative complications (2/32, 6.3%). Only 12 studies (37.5%) provided any patient reported outcomes. This study has demonstrated a deficiency and a lack of standardized variable and outcome reporting in the orthopaedic literature for Gustilo-Anderson type IIIB open tibial shaft fractures. We propose a future international collaborative Delphi process is needed to standardize

In an attempt to alleviate symptoms of the disease, patients with knee osteoarthrosis (KOA) frequently alter their gait patterns. Understanding the underlying pathomechanics and identifying KOA phenotypes is essential for improving treatments. We aimed to investigate altered kinematics in patients with KOA to identify subgroups. Sixty-six patients with symptomatic KOA scheduled for total knee arthroplasty and 12 age-matched healthy volunteers with asymptomatic knees were included. We used k-means to separate the patients based on dynamic radiostereometric assessed knee kinematics. Ligament lesions, KOA score, and clinical outcome were assessed by magnetic resonance imaging, radiographs, and patient reported outcome measures, respectively. We identified four clusters that were supported by clinical characteristics. Compared with the healthy group; The flexion group (n=20): revealed increased flexion, greater adduction, and joint narrowing and consisted primarily of patients with medial KOA. The abduction group (n=17): revealed greater abduction, joint narrowing and included primarily patients with lateral KOA. The anterior draw group (n=10): revealed greater anterior draw, external tibial rotation, lateral tibial shift, adduction, and joint narrowing. This group was composed of patients with medial KOA, some degree of anterior cruciate ligament lesion and the greatest KOA score. The external rotation group (n=19): revealed greater external tibial rotation, lateral tibial shift, adduction, and joint narrowing while no anterior draw was observed. This group included primarily patients with medial collateral and posterior cruciate ligament lesions. Patients with KOA can, based on their gait patterns, be classified into four subgroups, which relate to their clinical characteristics. The findings add to our understanding of associations between disease pathology characteristics in the knee and the pathomechanics in patients with KOA. A next step is to investigate if patients in the pathomechanic clusters have different outcomes following total knee arthroplasty

Excessive opioid prescriptions after total joint arthroplasty (TJA) increase risks for adverse opioid related events, chronic opioid use, and increase the availability of opioids for unlawful diversion. Thus, decreasing postoperative prescriptions may improve quality after TJA. Concerns exist that a decrease in opioids prescribed may increase complications such as readmissions, emergency department (ED) visits or worsened patient reported outcomes (PROs). The purpose of this quality improvement study was to explore whether a reduction in opioids prescribed after TJA resulted in increased complications. Methods: Data originated from a statewide arthroplasty database (MARCQI). The database collects over 96% of all TJA performed in the state of Michigan, USA. Data was prospectively abstracted and included OMEs prescribed at discharge, readmissions, ED visits within 30 days and PROs. Data was collected one year before and after the creation of an opioid prescribing protocol that had decreased prescriptions by approximately 50% in opioid naive and tolerant patients. Trends were monitored using Shewhart control charts. 84,998 TJA over two-years were included. All groups showed a reduction in opioids prescribed. Importantly, no increased complications occurred concomitant to this reduction. No increases in ED visits or readmissions, and no decreases in KOOSJR/HOOSJR/PROMIS10 scores were noted in any of the groups. Using large data sets and registries can drive performance and improve quality. The MARCQI Postoperative opioid prescription recommendations and performance measures decreased total oral morphine equivalents prescribed over a large and diverse population by approximately 50% without decreasing PROs or increasing ED visits or hospital readmissions. A reduction in opioids prescribed after TJA can be accomplished safely and without an increase in complications across a large population

This study aimed to quantify self-reported outcomes and walking gait biomechanics in patients following primary and revision THA. The specific goals of this study were to investigate: (i) if primary and revision THA patients have comparable preoperative outcomes; and (2) if revision THA patients have worse postoperative outcomes than primary THA patients. Forty-three patients undergoing primary THA for osteoarthritis and 23 patients undergoing revision THA were recruited and followed longitudinally for their first 12 postoperative months. Reasons for revision were loosening (73%), dislocation (9%), and infection (18%). Patients completed the Hip dysfunction and Osteoarthritis Outcome Score (HOOS), and underwent gait analysis preoperatively, and at 3 and 12 months postoperatively. A 10 camera motion analysis system (V5 Vantage, Vicon, UK) recorded marker trajectories (100 Hz) during walking at self- selected speeds. A generic lower-body musculoskeletal model (Gait2392) was scaled using principal component analysis [1] and the inverse kinematics tool in Opensim 3.3 was used to compute joint angles for the lower limbs in the sagittal plane. Independent samples t-test were used to compare patient reported outcomes between the primary and revision groups at each timepoint. Statistical parametric mapping was used to compare gait patterns between the two groups at each timepoint. Preoperatively, patients undergoing primary THA reported significantly worse pain (p<0.001), symptoms (p<0.001), function (p<0.001), and quality of life (p=0.004). No differences were observed at 3 and 12 months postoperatively between patients who had received a primary or revision THA. The only observed difference in gait pattern was that patients with a revision THA had reduced hip extension at 3 months, but no differences were observed preoperatively and 12 months. Despite the suggestions in the literature that revision THA is bound to have worse outcomes compared to primary THA, we found no differences in in patient-reported outcomes and gait patterns at 12 months postoperatively. This suggests that it may be possible, in some circumstances, for patients following revision THA to achieve similar outcomes to their peers undergoing primary THA

Tibial shaft fractures require surgical stabilization preferably by intramedullary nailing. However, patients often report functional limitations even years after the injury. This study investigates the influence of the surgical approach (transpatellar vs. parapatellar) on gait performance and patient reported outcome six months after surgery. Twenty-two patients with tibial shaft fractures treated by intramedullary nailing through a transpatellar approach (TP: n=15, age 41±15, BMI 24±3) or a parapatellar approach (PP: n=7, age 34±15, BMI 23±2) and healthy, matched controls (n=22, age 39±13, BMI 24±2) were assessed by instrumented motion analysis six months after intramedullary nailing. Short musculoskeletal function assessment questionnaire (SMFA) as well as kinematic and kinetic gait data were collected during level walking. Comparisons among approach methods and control group were performed by analysis of variance and Mann-Whitney test. Six months after surgery, knee kinetics in both groups differed significantly compared to controls (p <.04). The approach method affected gait speed (TP: p = .002; PP: p = .08) and knee kinematics in the early stance phase (TP: p = .011; PP: p = .082), with the parapatellar approach showing a more favorable outcome. However, the difference between patient groups was not significant for any of the assessed gait parameters (p > .2). Also, no differences could be found in the bother index (BI) or function index (FI) of SMFA between surgical approach methods (BI: TP: Mdn = 7.2, PP: Mdn = 9.4; FI: TP: Mdn = 10.3, PP: Mdn = 9.2, p > .7). Our study demonstrates, that six months after surgery for tibial shaft fractures functional limitations remain. These limitations appear not to be different for either a trans- or a parapatellar approach for the insertion of the intramedullary nail. The findings of this study are limited by the relatively short follow up time period and small number of patients. Future studies should investigate the source of the functional limitation after intramedullary nailing of tibial shaft fractures

The purpose of this study is to report the clinical and radiological outcomes of patients undergoing primary or revision reverse total shoulder arthroplasty using custom 3D printed components to manage severe glenoid bone loss with a minimum of 2-year follow-up. After ethical approval (reference: 17/YH/0318), patients were identified and invited to participate in this observational study. Inclusion criteria included: 1) severe glenoid bone loss necessitating the need for custom implants; 2) patients with definitive glenoid and humeral components implanted more than 2 years prior; 3) ability to comply with patient reported outcome questionnaires. After seeking consent, included patients underwent clinical assessment utilising the Oxford Shoulder Score (OSS), Constant-Murley score, American Shoulder and Elbow Society Score (ASES), and quick Disabilities of the Arm, Shoulder, and Hand Score (quickDASH). Radiographic assessment included AP and axial projections. Patients were invited to attend a CT scan to confirm osseointegration. Statistical analysis utilised included descriptive statistics (mean and standard deviation) and paired t test for parametric data. 3 patients had revision surgery prior to the 2-year follow-up. Of these, 2/3 retained their custom glenoid components. 4 patients declined to participate. 5 patients were deceased at the time of commencement of the study. 21 patients were included in this analysis. The mean follow-up was 36.1 months from surgery (range 22–60.2 months). OSS improved from a mean 16 (SD 9.1) to 36 (SD 11.5) (p < 0.001). Constant-Murley score improved from mean 9 (SD 9.2) to 50 (SD 16.4) (p < 0.001). QuickDASH improved from mean 67 (SD 24) to 26 (SD 27.2) (p = 0.004). ASES improved from mean 28 (SD 24.8) to 70 (SD 23.9) (p = 0.007). Radiographic evaluation demonstrated good osseointegration in all 21 included patients. The utility of custom 3D-printed components for managing severe glenoid bone loss in primary and revision reverse total shoulder arthroplasty yields significant clinical improvements in this complex patient cohort

Open talus fracture are notoriously difficult to manage and they are commonly associated with a high level of complications including non-union, avascular necrosis and infection. Currently, the management of such injuries is based upon BOAST 4 guidelines although there is no suggested definitive management, thus definitive management is based upon surgeon preference. The key principles of open talus fracture management which do not vary between surgeons, however, there is much debate over whether the talus should be preserved or removed after open talus fracture/dislocation and proceeded to tibiocalcaneal fusion. A review of electronic hospital records for open talus fractures from 2014-2021 returned foureen patients with fifteen open talus fractures. Seven cases were initially managed with ORIF, five cases were definitively managed with FUSION, while the others were managed with alternative methods. We collected patient's age, gender, surgical complications, surgical risk factors and post-treatment functional ability and pain and compliance with BOAST guidelines. The average follow-up of the cohort was four years and one month. EQ-5D-5L and FAAM-ADL/Sports score was used as a patient reported outcome measure. Data was analysed using the software PRISM. Comparison between FUSION and ORIF groups showed no statistically significant difference in EQ-5D-5L score (P = 0.13), FAAM-ADL (P = 0.20), FAAM-Sport (P = 0.34), infection rate (P = 0.55), surgical times (P = 0.91) and time to weight bearing (P = 0.39), despite a higher proportion of polytrauma and Hawkins III and IV fractures in the FUSION group. FUSION is typically used as second line to ORIF or failed ORIF. However, there are a lack of studies that directly compared outcome in open talus fracture patients definitively managed with FUSION or ORIF. Our results demonstrate for the first time, that FUSION may not be inferior to ORIF in terms of patient functional outcome, infection rate, and quality-of-life, in the management of patients with open talus fracture patients. Of note, as open talus fractures have increased risks of complications such as osteonecrosis and non-union, FUSION should be considered as a viable option to mitigate these potential complications in these patients

Abstract. Objectives. There is still controversy in the literature over whether Cervical Foraminotomy or Anterior Cervical discectomy and fusion (ACDF) is best for treating cervical Radiculopathy. Numerous studies have focused on the respective complication rates of these procedures and outcome measures with a lack of due consideration to preoperative MRI findings. Proximal foraminal stenosis can theoretically be accessed via either approach. We aimed to investigate whether patient reported outcome measures (PROMs) favoured one approach over the other in patients with proximal foraminal stenosis. Methods. A single centre retrospective review of patients undergoing either ACDF or Cervical foraminotomy over the period 2012 to 2022. VAS, Neck disability index (NDI), EQ5DL and Patient Satisfaction on a Five Point Likert scale were obtained. Patients who had both an ACDF and a Foraminotomy were excluded. Axial MRI images were analysed and the location of the worst clinically relevant disc herniation stratified as follows: Central (1), Paracentral (2) and Foraminal (3). Correlations and average PROMs were analysed in SPSS. Results. PROMs scores were available for 33 ACDF patients and 37 Foraminotomy patients. Average surgery time in ACDF group was 167 minutes while Foraminotomy 142 minutes. Average Length of hospital stay was 6.24 days in the Foraminotomy group and 3.54 days in the ACDF group. 18 patients were excluded due to having both surgeries (2 of which developed CSF leaks postoperatively). Of the included patients there were no postoperative complications. 13 patients in the ACDF had Central or Paracentral stenosis in addition to proximal Foraminal stenosis, 3 patients in the Foraminotomy group had some significant Paracentral herniation just before the Proximal foramen. The majority of patients in both groups had pure proximal Foraminal stenosis (N= 17 (ACDF), 20 (Foraminotomy). The results showed no significant difference in PROMs between patients who received an ACDF or a Foraminotomy for Proximal foraminal stenosis (EQ5DL, NDI, and satisfaction, P= 0.268, 0.253 and 0.327). There was no correlation between location of the stenosis and PROM scores in either group. Conclusions. Our data suggest that Proximal foraminal stenosis can be effectively addressed by either an anterior ACDF or a Foraminotomy with no difference in complication rates. Foraminotomy has the benefit of no implant cost but longer hospital stay. Declaration of Interest.

Abstract. Objectives. Outcomes following different types of surgical intervention for FAI are well reported individually but comparative data is deficient. The purpose of this study was to conduct a systematic review (SR) and meta-analysis to analyse the outcomes following surgical management of FAI by hip arthroscopy (HA), anterior mini open approach (AMO) and surgical hip dislocation (SHD). Methods. This SR was registered with PROSPERO. An electronic database search of Pubmed, Medline and EMBASE for English and German language articles over the last 20 years was carried out according to the PRISMA guidelines. We specifically analysed and compared changes in patient reported outcome measures PROMs, α-angle, rate of complications, rate of revision and conversion to total hip arthroplasty (THA). Results. A total of 48 articles included for final analysis with a total of 4384 hips in 4094 patients. All subgroups showed a significant correction in mean alpha angle post-operatively with a mean change of 28.8° (95% CI, 21°-36.5°; p <0.01) after AMO, 21.1° (95% CI, 15.1°-27°; p <0.01) after SHD and 20.39° (95% CI, 15.66°-25.12°; p <0.01) after HA. AMO group showed a significantly higher increase in PROMs (3.7; 95% CI, 3.2–4.2; p <0.01) versus arthroscopy (2.47; 95% CI, 2.22–2.73; p <0.01) and SHD (2.4; 95% CI, 1.5–3.3; p <0.01). However, the rate of complications following AMO was significantly higher than HA and SHD. Conclusion. All three surgical approaches offered significant improvements in outcomes and radiological correction of cam deformities. All three groups showed similar rates of revision procedures and SHD had the highest rate of conversion to a THA. Revision rates was similar for all three revision procedures

Introduction and Objective. Evidence in literature is contradicting regarding outcomes of total knee arthroplasty (TKA) in post-traumatic osteoarthritis (PTOA) and whether they are inferior to TKA in primary osteoarthritis (OA). The aim of this review was to find out if any difference exists in the results of TKA between the two indications. Materials and Methods. The electronic databases MEDLINE, EMBASE, The Cochrane Collaboration, and PubMed were searched and screened in duplicate for relevant studies. The selected studies were further subjected to quality assessment using the modified Coleman method. The primary outcome measure was patient reported outcome, and secondary outcome measures were infection, revision, stiffness, and patella tendon rupture. Results. A total of 18 studies involved 1129 patients with a mean age of 60.6 years (range 45.7–69) and follow up of 6.3 years. The time interval from index injury to TKA was 9.1 years. Knee Society Score (KSS) in PTOA reported in 12/18 studies showed functional improvement from 42.5 to 70 post-TKA exceeding minimally clinically important difference. In TKA for primary OA vs PTOA, deep peri-prosthetic joint infection (PJI) was reported in 1.9% vs 5.4% of patients, whilst revision of prosthesis at an average of 6 years post-operatively was performed in 2.6 vs 9.7% of patients. Conclusions. TKA is a successful treatment option for PTOA. However, the risk of significant complications like PJI and implant failure requiring revision is higher than primary OA cases. Patients should be counselled about those risks. Further well-designed comparative cohort-matched studies are needed to compare outcomes between the two populations

Abstract. Background/Objectives. The incidence of reverse total shoulder replacement (rTSR) implantation is increasing globally, but apprehension exists regarding complications and associated challenges. We retrospectively analysed the senior author's series of rTSR from a tertiary centre using the VAIOS shoulder system, a modular 4th generation implant. We hypothesised that the revision rTSR cohort would have less favourable outcomes and more complications. Methods. 114 patients underwent rTSR with the VAIOS system, over 7 years. The primary outcome was implant survival. Secondary outcomes were Oxford shoulder scores (OSS), radiographic analysis (scapular notching, tuberosity osteolysis, and periprosthetic radiolucent lines) and complications. Results. There were 55 Primary rTSR, 31 Revision rTSR and 28 Trauma rTSR. Implant survival: Primary rTSR- 0 revisions, average 3.35-year follow-up. Revision rTSR-1 revision (4.17%), average 3.52-year follow-up. Trauma rTSR- 1 revision (3.57%), average 4.56-year follow-up OSS: Average OSS improved from 15.39 to 33.8 (Primary rTSR) and from 15.11 to 29.1 (Revision rTSR). Average post-operative OSS for the Trauma rTSR was 31.4 Radiological analysis and complications: Low incidence of scapular notching One hairline fracture below the tip of stem, noted incidentally, which required no treatment. One periprosthetic fracture after alcohol related fall. Treated non-surgically One joint infection requiring two-stage revision to rTSR. One dislocation noted at 2 year follow up. This patient had undergone nerve grafting within 6 months of rTSR for axillary nerve injury sustained during the original fracture dislocation. One acromial fracture with tibial and distal humeral fracture after a fall. Conclusions. The 4th generation modular VAIOS implant is a reliable option for various indications. The revision rTSR cohort had favourable outcomes with low complication rates. In this series, early-to-medium term results suggest lower revision rates and good functional outcomes when compared to published reports. We plan to monitor long-term implant survivorship and patient reported outcomes. Declaration of Interest. (a) fully declare any financial or other potential conflict of interest

Introduction and Objective. Tranexamic acid (TXA) is used across surgical specialties to reduce perioperative bleeding. It has been shown to be effective in trauma, spinal surgery, and lower limb arthroplasty. The aim of this study is to investigate the clinical effectiveness of TXA in all types of shoulder surgery on bleeding and non-bleeding related outcomes. Materials and Methods. This study was registered prospectively on the PROSPERO database (ref: CRD42020185482). A systematic review and meta-analysis of randomised controlled trials (RCTs) investigating intra-operative use of TXA versus placebo in any type of surgery to the shoulder girdle. Electronic databases searched included MEDLINE, EMBASE, PsychINFO, and the Cochrane Library. Risk of bias within studies was assessed using the Cochrane risk of bias v2.0 tool and Jadad score. Certainty of findings were reported using the GRADE approach. The primary outcome was total blood loss. Secondary outcomes included patient reported outcome measures, adverse events, and rate of blood transfusion. Results. Eight RCTs were included in the systematic review and data from 7 of these studies pooled in the meta-analysis. A total of 708 patients were randomized across the studies (406 received TXA, 302 received placebo). Studies included patients undergoing anatomic or reverse total shoulder arthroplasty, open Latarjet surgery, and arthroscopic rotator cuff repair. Pooled analysis demonstrated significant reduction in perioperative bleeding with TXA compared to controls; estimated total blood loss (mean difference [MD], −209.66; 95% CI −389.11 to −30.21; p=0.02), and post-operative blood loss (via drain output) (MD, −84.8ml; 95% CI, −140.04 to −29.56; p=0.003). A mean difference in Visual Analogue Scale (VAS) of 2.93 was noted in favour of TXA (95% CI 0.2 to 5.66; p=0.04). Conclusions. Whilst noting some risk of bias within the studies, TXA was effective in reducing blood loss and pain in shoulder surgery. There may be a benefit of TXA use in both open and arthroscopic shoulder procedures. Larger, low risk of bias, RCTs for specific surgical shoulder procedures are required

Introduction and Objective. An important subset of patients is dissatisfied after total joint arthroplasty (TJA) due to residual functional impairment. This study investigated the assessment of objectively measured step-up performance following TJA, to identify patients with poor functional improvement after surgery, and to predict residual functional impairment during early postoperative rehabilitation. Secondary, longitudinal changes of block step-up (BS) transfers were compared with functional changes of subjective patient reported outcome measures (PROMs) following TJA. Materials and Methods. Patients with end stage hip or knee osteoarthritis (n = 76, m/f = 44/32; mean age = 64.4 standard deviation 9.4 years) were measured preoperatively and 3 and 12 months postoperatively. PROMs were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) function subscore. BS transfers were assessed by wearable-derived measures of time. In our cohort, subgroups were formed based on either 1) WOMAC function score or 2) BS performance, isolating the worst performing quartile (impaired) of each measure from the better performing others (non-impaired). Subgroup comparisons were performed with the Man-Whitney-U test and Wilcoxon Signed rank test resp. Responsiveness was calculated by the effect size, correlations with Pearson's correlation coefficient. A regression analysis was conducted to investigate predictors of poor functional outcome. Results. WOMAC function scores were strongly correlated to WOMAC pain scores (Pearson's r=0.67–0.84) and moderately correlated to BS performance (Pearson's r = 0.31–0.54). Prior to surgery, no significant differences for WOMAC function scores and BS performance were found between the impaired and non-impaired subgroups. One year after TJA, our cohort performed significantly better at WOMAC and BS with largest effect size for the non-impaired subgroups (0.62 and 0.43 resp.) At 12 months postop, 56% of patients allocated to the impaired subgroup defined by WOMAC, represented the impaired subgroup defined by BS. Allocation to the impaired subgroup at 3 months postop, raised the odds for belonging to the impaired subgroup at 12 months for WOMAC with an odds ratio=19.14 (67%) and for BS with an odds ratio=4.41 (42%). Conclusions. Assessment of BS performance following TJA reveals residual functional impairment that is not captured by pain-dominated PROMs. Its additional use may help to early identify those patients at risk for a poor outcome

Abstract. Background. Whilst the literature abounds with patient reported outcomes following total knee replacement (TKR) there is a paucity of literature covering objective functional outcomes. Awareness of objective functional outcomes following TKR is key to the consent process and relating it to pre-operative function enables a tailored approach to consent. Objectives. Identify trends in a range of functional outcomes prior to and following TKR up to one year post-operatively. Methods. We prospectively gathered data from 82 patients undergoing TKR, examining over 20 functional measures preoperatively and postoperatively at 6 weeks, 3, 6 and 12 months. Our functional lab incorporated validated assessments and assessments selected by surgeons & physiotherapists seen to be critical to outcomes following TKR, such as: kneeling ability, 6 minute walking distance, time to ascend/descend stairs, quadricep moment strength, single stance difficulty, ability to walk on an uneven surface, “Time to get up and go”, upslope/downslope speed. Results. Our results demonstrated that if a patient was able to kneel preoperatively they had an 82.5% chance of being able to kneel postoperatively; if they could not kneel preoperatively this dropped to only 50% but overall over two-thirds of patients were able to kneel at 1 year postoperatively. Other selected results include: 49% increase in 6-minute walking distance, 45% reduction in time to ascend then descend stairs, over 50% increase in quadriceps moment strength, over 40% increase in both upslope/downslope speed and over 70% reduction in difficulty walking on an uneven surface. Conclusions. With these results we can not only discuss specific functional outcomes following TKR but also relate these to preoperative functional level, enabling a more tailored, detailed and robust consent process.

The modified Hedgehog technique was previously used to reattach pure chondral shear-off fragments in the pediatric knee. In the modified Hedgehog technique, the calcified side of chondral fragments is multiple times incised and trimmed obliquely for an interlocking fit in the defect site. Fibrin glue with or without sutures is subsequently applied to fix the fragment to the defect. This preliminary report further elucidates the potential of the technique by evaluation of its application in young adults using patient reported outcome measures (PROMs) and high-field Magnetic Resonance Imaging (MRI) as outcome measures. Three patients with a femoral cartilage defect (2 medial, 1 lateral), and a concomitant pure chondral corpus liberum were operatively treated by the modified Hedgehog technique. Age at surgery ranged from 20.6–21.2 years, defect size ranged from 3.8–6.0 cm2. Patients were evaluated at three months and one year after surgery by PROMs and 7.0T MRI. PROMs included the Internation Knee Documentation (IKDC), Knee Injury and Osteoarthritis Outcome Score (KOOS) and Visual Analog Scale (VAS) questionnaires. 7.0T MRI (Magnetom, Siemens Healthcare, Erlangen, Germany) using a 28-channel proton knee coil (QED, Electrodynamics LLC, Cleveland, OH) included a proton density weighted turbo spin-echo sequence with fat suppression to assess morphological tissue structure andgagCEST imaging to measure the biochemical tissue composition in terms of glycosaminoglycans (GAG). Twelve months after surgery all patients reported no pain and showed full range of motion. While PROMs at three months showed large variability between patients, one year after surgery the scores were consistently improved. Over time, morphological MRI visualized improvements in integration of the cartilage fragment with the surrounding cartilage, which was supported by biochemical MRI showing increased GAG values at the defect edges. Statistics were not applied to the results because of the small sample size. The modified Hedgehog technique in young adults with an acute onset caused by a pure chondral corpus liberum can be considered promising. The improved PROM results over time were supported by 7.0T MRI that visualized improvements in tissue structure and biochemical composition. Inclusion of more patients in future studies would allow statistical analysis and more conclusive results. The etiology of loosening and time between onset of symptoms and surgery for successful graft integration may differ between pediatric and young adult patients and is subject for future studies

Telemedicine is the delivery of healthcare from a remote location using integrated computer/communication technology. This systematic review aims to explore evidence for telemedicine in orthopaedics to determine its advantages, validity, effectiveness and utilisation particularly during our current pandemic where patient contact is limited. Databases of PubMed, Scopus and CINHAL were systematically searched and articles were included if they involved any form of telephone or video consultation in an orthopaedic population. Findings were synthesised into four themes: patient/clinician satisfaction, accuracy and validity of examination, safety and patient outcomes and cost effectiveness. Quality assessment was undertaken using Cochrane and Joanna Briggs Institute appraisal tools. Twenty studies were included consisting of nine RCTs across numerous orthopaedic subspecialties including fracture care, elective orthopaedics and oncology. Studies revealed high patient satisfaction with telemedicine for convenience, less waiting and travelling time. Telemedicine was cost effective particularly if patients had to travel long distances, required hospital transport or time off work. No clinically significant differences were found in patient examination nor measurement of patient reported outcome measures. Telemedicine was reported to be a safe method of consultation. However, studies were of variable methodological quality with selection bias. In conclusion, evidence suggests that telemedicine in orthopaedics can be safe, cost effective, valid in clinical assessment with high patient/clinician satisfaction. Further work with high quality RCTs is required to elucidate long term outcomes. This systematic review presents up-to-date evidence on the use of telemedicine and provides data for organisations considering its use in the current COVID-19 pandemic and beyond

Introduction. Progressive resistance training (PRT) as a mean to reduce symptoms in patients with hip dysplasia (HD) has not yet been tried out. The aim of this study was to examine if PRT is feasible in patients with HD. A secondary purpose was to report data on changes of patient reported outcomes, muscle performance and hip muscle strength following PRT. Materials and methods. Patients diagnosed with HD on the waiting list for a periacetabular osteotomy (PAO) were offered to participate in a PRT feasibility study. The PRT intervention consisted of 8-weeks of supervised PRT consisting of 20 training sessions with exercises for the hips and knees. Feasibility was evaluated as adherence, the number of dropouts and adverse events. Furthermore, pain was reported after each exercise and one day after a training session using a 100mm visual analog scale (VAS). Pain was categorized as “safe” (VAS ≤20), “acceptable” (VAS >20–50) and “high risk” (VAS >50). Pre- and post the intervention patients completed the Copenhagen Hip and Groin Outcome Score (HAGOS), performed two hop-tests on each leg and had their peak torque of the hip extensors and flexors assessed by isokinetic dynamometry. Results. 16 patients, mean age 28 (range 22–40) years, completed the PRT intervention. Adherence was high (90.3% ±9.0%). Acceptable pain levels (VAS ≤50) were reported on average of 95% during the completed PRT sessions and after 92.3% of the sessions when assessed on the following day. Four out of six HAGOS subscales improved (P <0.05) after the intervention, as did standing distance jump and countermovement jump (8.3 cm 95% CI [1.2, 15.3], 1.8 cm [0.7, 2.9]) on the affected side. Dynamometry showed significant improved peak torque during isokinetic concentric hip flexion (15.8 Nm 95% CI [5.9, 25.8]) on the affected side. A similar improvement was seen during isometric hip flexion on the non-affected side. Conclusion. Supervised preoperative PRT is feasible in terms of drop outs, adherence, adverse events and pain levels in patients with HD scheduled for PAO. Furthermore, this feasibility study suggests that PRT may improve pain levels, patient reported outcomes, functional performance and hip flexion muscle strength
