Functional Outcomes and Satisfaction Rates in Patients Aged 80 Years or Older are Not Clinically Different From Their Younger (65 to 75 Years) Counterparts Following Total Hip Arthroplasty.

BACKGROUND: As the population ages, the proportion of elderly patients requiring total hip arthroplasty (THA) increases, but it is not clear whether older age independently influences outcome. The aim was to assess function, quality of life, and satisfaction after THA in patients ≥ 80 years compared with those aged between 65 and 75 years when adjusting for confounding factors. METHODS: A single-center retrospective cohort study was performed between 2010 and 2019. A total 2,367 THAs were performed on patients ≥ 80 years and 5,113 on patients aged 65 to 75 years. The demographic data and length of stay (LOS) were recorded. Preoperative and 2-year postoperative Oxford Hip Scores (OHS), EuroQol (EQ-5D), and satisfaction scores were collected. Clinically meaningful difference was defined as 5 points in OHS and utility of 0.085 in EQ-5D. Regression analyses were performed to adjust for confounding factors. RESULTS: Patients in ≥ 80-years group were more likely women (P < .001), have higher American Society of Anesthesiolgists grade (P < .001), worse preoperative OHS (mean difference [MD] 2.3, P < .001), and EQ-5D (MD 0.087, P < .001). Both age groups achieved clinically meaningful and statistically significant (P < .001) improvement in OHS and EQ-5D utility at 2 years. When adjusting for confounding variables, the ≥ 80-year-old group had significantly (P < .001) lower improvement in OHS (MD -1.9 points) and EQ-5D (MD -0.055 utility), but these differences were not clinically meaningful. There was no difference (P = .813) in satisfaction between the groups. When adjusting for confounding variables, ≥ 80-year-old group had increased risk of longer LOS (odds ratio 1.27, P < .001). CONCLUSIONS: There were no clinically meaningful differences in hip-specific outcome or health-related quality of life according to age group, and both were equally satisfied with their outcome. The older age group did, however, have longer LOS. LEVEL OF EVIDENCE: Level III retrospective cohort study.

Epidemiology of musculoskeletal injury in professional and amateur golfers: a systematic review and meta-analysis.

OBJECTIVE: To determine the prevalence and incidence of musculoskeletal injury in amateur and professional golfers, and to identify common injury sites and factors associated with increased injury frequency. DESIGN: Systematic epidemiological review and meta-analysis. DATA SOURCES: PubMed (Medline), Embase, the Cochrane Library and SPORTDiscus were searched in September 2023. ELIGIBILITY CRITERIA: Studies published in the English language reporting the incidence or prevalence of musculoskeletal injuries in golfers at all anatomical sites. RESULTS: 20 studies (9221 golfers, 71.9% male, 28.1% female) were included, with mean age 46.8 years. Lifetime injury prevalence was significantly greater in professional golfers (73.5% (95% CI: 47.3% to 93.0%)) than amateur golfers (56.6% (95% CI: 47.4% to 65.5%); relative risk (RR)=1.50, p<0.001). Professional golfers had a significantly greater lifetime prevalence of hand and wrist (RR=3.33, p<0.001) and lower back injury (RR=3.05, p<0.001). Soft tissue injuries were most common, and diagnoses were typically non-specific. Injury frequency was not associated with age or sex. Two studies reported a greater injury risk in amateur golfers playing more than three and four rounds per week. CONCLUSION: Over half of golfers are at risk of sustaining a musculoskeletal injury during their lifetime. Risks and patterns of injury differ between professional and amateur golfers, with professionals significantly more likely to develop lower back, and hand and wrist injuries. A recent international consensus statement on the reporting of injury and illness in golf should aid consistency in future research assessing the epidemiology of specific diagnoses, informing golf injury prevention and management strategies.

A preoperative package of care for osteoarthritis, consisting of weight loss, orthotics, rehabilitation, and topical and oral analgesia (OPPORTUNITY): a two-centre, open-label, randomised controlled feasibility trial.

BACKGROUND: Osteoarthritis of the knee is a major cause of disability worldwide. Non-operative treatments can reduce the morbidity but adherence is poor. We hypothesised that adherence could be optimised if behavioural change was established in the preoperative period. Therefore, we aimed to assess feasibility, acceptability, and recruitment and retention rates of a preoperative package of non-operative care in patients awaiting knee replacement surgery. METHODS: We did an open-label, randomised controlled, feasibility trial in two secondary care centres in the UK. Eligible participants were aged 15-85 years, on the waiting list for a knee arthroplasty for osteoarthritis, and met at least one of the thresholds for one of the four components of the preoperative package of non-operative care intervention (ie, weight loss, exercise therapy, use of insoles, and analgesia adjustment). Participants were randomly assigned (2:1) to either the intervention group or the standard of care (ie, control) group. All four aspects of the intervention were delivered weekly over 12 weeks. Participants in the intervention group were reviewed regularly to assess adherence. The primary outcome was acceptability and feasibility of delivering the intervention, as measured by recruitment rate, retention rate at follow-up review after planned surgery, health-related quality of life, joint-specific scores, and adherence (weight change and qualitative interviews). This study is registered with ISRCTN, ISRCTN96684272. FINDINGS: Between Sept 3 2018, and Aug 30, 2019, we screened 233 patients, of whom 163 (73%) were excluded and 60 (27%) were randomly assigned to either the intervention group (n=40) or the control group (n=20). 34 (57%) of 60 participants were women, 26 (43%) were men, and the mean age was 66·8 years (SD 8·6). Uptake of the specific intervention components varied: 31 (78%) of 40 had exercise therapy, 28 (70%) weight loss, 22 (55%) analgesia adjustment, and insoles (18 [45%]). Overall median adherence was 94% (IQR 79·5-100). At the final review, the intervention group lost a mean of 11·2 kg (SD 5·6) compared with 1·3 kg (3·8) in the control group (estimated difference -9·8 kg [95% CI -13·4 to -6·3]). A clinically significant improvement in health-related quality o life (mean change 0·078 [SD 0·195]) were reported, and joint-specific scores showed greater improvement in the intervention group than in the control group. No adverse events attributable to the intervention occurred. INTERPRETATION: Participants adhered well to the non-operative interventions and their health-related quality of life improved. Participant and health professional feedback were extremely positive. These findings support progression to a full-scale effectiveness trial. FUNDING: Versus Arthritis.

Primary Versus Secondary Total Knee Arthroplasty for Tibial Plateau Fractures in Patients Aged 55 or Over-A Systematic Review and Meta-Analysis.

BACKGROUND: Total knee arthroplasty allows immediate postoperative weight-bearing and is increasingly recognized as a suitable treatment option for older patients who have tibial plateau fractures (TPFs). This systematic review evaluated the clinical and functional outcomes associated with primary versus secondary TKA for the treatment of TPFs in patients aged ≥55 years. METHODS: Various databases were searched from inception to December 2021. Studies investigating outcomes of primary TKA (pTKA) as the initial treatment for TPFs in patients of mean age ≥55 years or those investigating outcomes of secondary TKA (sTKA) following any other primary treatment for TPFs were included. Quality of included studies was assessed using a methodological scale. Of 767 potentially relevant studies, 12 studies comprising 341 patients were included: 121 patients underwent (pTKA) and 220 patients underwent sTKA. There were 3 high-quality studies. Patients in the sTKA cohort were significantly younger at the time of TKA compared with those undergoing pTKA (mean 61.3 versus 72.2 years, P < .001, 95% confidence interval (CI) 8.2 to 13.6). RESULTS: Intraoperative and postoperative complication rates were lower with pTKA; in particular, sTKA was associated with a significantly increased rate of stiffness requiring reintervention and patella tendon rupture. Functional outcome was greater after pTKA, but this did not reach statistical significance (85.2 versus 79.9%, P = .359, 95% CI -16.7 to 6.1). CONCLUSION: Primary TKA was associated with lower complication rates than secondary TKA after TPF. In appropriate cases of TPF in older adults, it may be preferable to proceed with TKA as primary treatment rather than delaying until after fracture union or malunion.

Ultrasound assessment of humeral shaft nonunion risk: a feasibility and proof of concept study.

PURPOSE: To determine the feasibility and reliability of ultrasound in the assessment of humeral shaft fracture healing and estimate the accuracy of 6wk ultrasound in predicting nonunion. METHODS: Twelve adults with a non-operatively managed humeral shaft fracture were prospectively recruited and underwent ultrasound scanning at 6wks and 12wks post-injury. Seven blinded observers evaluated sonographic callus appearance to determine intra- and inter-observer reliability. Nonunion prediction accuracy was estimated by comparing images for patients that united (n = 10/12) with those that developed a nonunion (n = 2/12). RESULTS: The mean scan duration was 8 min (5-12) and all patients tolerated the procedure. At 6wks and 12wks, sonographic callus (SC) was present in 11 patients (10 united, one nonunion) and sonographic bridging callus (SBC) in seven (all united). Ultrasound had substantial intra- (weighted kappa: 6wk 0.75; 12wk 0.75) and inter-observer reliability (intraclass correlation coefficient: 6wk 0.60; 12wk 0.76). At 6wks, the absence of SC demonstrated sensitivity 50%, specificity 100%, positive predictive value (PPV) 100% and negative predictive value (NPV) 91% in nonunion prediction (overall accuracy 92%). The absence of SBC demonstrated sensitivity 100%, specificity 70%, PPV 40% and NPV 100% in nonunion prediction (overall accuracy 75%). Of three patients at risk of nonunion (Radiographic Union Score for HUmeral fractures < 8), one had SBC on 6wk ultrasound (that subsequently united) and the others had non-bridging/absent SC (both developed nonunion). CONCLUSIONS: Ultrasound assessment of humeral shaft fracture healing was feasible, reliable and may predict nonunion. Ultrasound could be useful in defining nonunion risk among patients with reduced radiographic callus formation.

Editorial: factors influencing the outcome of total hip and knee arthroplasty.

BACKGROUND: Total hip and knee arthroplasty for end stage arthritis are among the most cost-effective interventions available in all of medicine. Success of hip and knee arthroplasties is not universal and approximately one in ten patients are not satisfied with their arthroplasty and 10 to 34% of patients have an unfavourable long term pain outcome. The aim of this edition of Arthroplasty was to identify factors associated with: (1) poor joint specific outcome, (2) poor health related quality of life outcome and (3) dissatisfaction following total hip and knee arthroplasty. METHODS: The scope was deliberately broad to identify factors (known and unknown) that influence outcome of total hip and knee arthroplasty, and of 40 submissions, eight were selected for this special edition after peer review. RESULTS: Many of the included studies reported subjective patient reported outcome measures as their key outcomes but other objective measures such as muscle mass, timed Up-and-Go test, kneeling ability and postoperative pain are also featured. Some studies involved a focus on early rehabilitation after surgery (ERAS) principles and how to optimise pre-rehabilitation and reduce length of hospital stay readmission and reoperation. The effect of metal allergy and drain usage on outcomes is also explored. A variety of methodologies have been used including one randomised control trial, some machine learning and three systematic reviews investigating the effect of metal allergy on outcomes, associations with postoperative pain and the effect of patella resurfacing. CONCLUSION: This special edition has advanced our knowledge of factors influencing to the outcome of hip and knee arthroplasty but has also identified several areas of research that need to be addressed to improve the outcomes of our patients.

Lessons learned from hip fracture registries - From the Scottish perspective to global practice.

Hip fracture is the most common serious orthopaedic injury affecting older people. In Scotland, 7000 patients sustain a hip fracture each year, and this is projected to rise to 10,300 a year by 2029. In this narrative review, we describe the origin and evolution of the Scottish Hip Fracture Audit, including key elements which have improved hip fracture care and outcomes within Scotland, and the current state of play of hip fracture registries around the world. We go on to discuss future directions for data driven improvements in hip fracture care, including international standardised data collection and a global minimum common dataset for hip fracture registries.

QuickDASH and PRWE Are Not Optimal Patient-Reported Outcome Measures After Distal Radial Fracture Due to Ceiling Effect: Potential Implications for Future Research.

BACKGROUND: The aim of this study was to determine the floor and ceiling effects for both the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire) and the PRWE (Patient-Rated Wrist Evaluation) following a distal radial fracture (DRF). Secondary aims were to determine the degree to which patients with a floor or ceiling effect felt that their wrist was "normal" according to the Normal Wrist Score (NWS) and if there were patient factors associated with achieving a floor or ceiling effect. METHODS: A retrospective cohort study of patients in whom a DRF was managed at the study center during a single year was undertaken. Outcome measures included the QuickDASH, PRWE, EuroQol-5 Dimensions-3 Levels (EQ-5D-3L), and NWS. RESULTS: There were 526 patients with a mean age of 65 years (range, 20 to 95 years), and 421 (80%) were female. Most patients were managed nonsurgically (73%, n = 385). The mean follow-up was 4.8 years (range, 4.3 to 5.5 years). A ceiling effect was observed for both the QuickDASH (22.3% of patients with the best possible score) and the PRWE (28.5%). When defined as a score that differed from the best available score by less than the minimum clinically important difference (MCID) for the scoring system, the ceiling effect increased to 62.8% for the QuickDASH and 60% for the PRWE. Patients who had a ceiling score on the QuickDASH and the PWRE had a median NWS of 96 and 98, respectively, and those who had a score within 1 MCID of the ceiling score reported a median NWS of 91 and 92, respectively. On logistic regression analysis, a dominant-hand injury and better health-related quality of life were the factors associated with both QuickDASH and PRWE ceiling scores (all p < 0.05). CONCLUSIONS: The QuickDASH and PRWE demonstrate ceiling effects when used to assess the outcome of DRF management. Some patients achieving ceiling scores did not consider their wrist to be "normal." Future research on patient-reported outcome assessment tools for DRFs should aim to limit the ceiling effect, especially for individuals or groups that are more likely to achieve a ceiling score.

Radiolucent line assessment in cemented stemmed total knee (RISK) arthroplasty: validation of a modernized classification system.

BACKGROUND: This study aims to implement and assess the inter- and intra-reliability of a modernized radiolucency assessment system; the Radiolucency In cemented Stemmed Knee (RISK) arthroplasty classification. Furthermore, we assessed the distribution of regions affected by radiolucency in patients undergoing stemmed cemented total knee arthroplasty. METHODS: Stemmed total knee arthroplasty cases over 7-year period at a single institution were retrospectively identified and reviewed. The RISK classification system identifies five zones in the femur and five zones in the tibia in both the anteroposterior (AP) and lateral planes. Post-operative and follow-up radiographs were scored for radiolucency by four blinded reviewers at two distinct time points four weeks apart. Reliability was assessed using the kappa statistic. A heat map was generated to demonstrate the reported regions of radiolucency. RESULTS: 29 cases (63 radiographs) of stemmed total knee arthroplasty were examined radiographically using the RISK classification system. Intra-reliability (0.83) and Inter-reliability (0.80) scores were both consistent with a strong level of agreement using the kappa scoring system. Radiolucency was more commonly associated with the tibial component (76.6%) compared to the femoral component (23.3%), and the tibial anterior-posterior (AP) region 1 (medial plateau) was the most affected (14.9%). CONCLUSION: The RISK classification system is a reliable assessment tool for evaluating radiolucency around stemmed total knee arthroplasty using defined zones on both AP and lateral radiographs. Zones of radiolucency identified in this study may be relevant to implant survival and corresponded well with zones of fixation, which may help inform future research.

Robotic-arm Assisted Total Knee Arthroplasty: the Relationship between Bone Resection, Gap Balancing and Resultant Implant Alignment.

Objectives: The primary aim was to assess the association between bone resection and the resultant flexion and extension gaps in the medial and lateral compartments of the knee when performing robotic-arm assisted total knee arthroplasty (rTKA). The secondary aims were to compare medial and lateral bone resections and the influence on limb alignment, and whether the amount of bone resection that resulted in equal gaps was predictable. Methods: A prospective study of 22 consecutive patients with a mean age of 66 years undergoing rTKA was conducted. The femoral component was mechanically aligned, and the alignment of the tibial component was adjusted (+/-3degrees of the mechanical axis) to obtain equal extension and flexion gaps. All knees underwent soft tissue balancing using sensor-guided technology. The final compartmental bone resection, gaps, and implant alignment were obtained from the robot data archive. Results: There was a correlation between bone resection and the resultant gap in the medial (r=0.433, p=0.044) and lateral (r=0.724, p<0.001) compartments of the knee. There were no differences in bone resection from the distal femur and posterior condyles in the medial (p=0.941) or lateral compartments (p=0.604) or for the resultant gaps (p=0.341 and p=0.542, respectively). There was more bone removed from the medial compartment compared to the lateral aspect: 0.9mm (p=0.005) in extension and 1.2mm (p=0.026) flexion. The differential bone resection changed the knee alignment by one degree of varus. There were no significant differences between the actual and predicted medial (difference 0.05, p=0.893) or lateral (difference 0.00, p=0.992) tibial bone resection. Conclusion: There was a direct association between bone resection and resultant compartment joint gap when using rTKA, which was predictable. Gap balancing was achieved when less bone was resected from the lateral compartment which resulted in an estimated one-degree varus alignment of the knee.

Reliability of patient-reported comorbidities: a systematic review and meta-analysis.

Self-reported questionnaires have become a widely adopted method of reviewing patients in clinical practice. This systematic review aimed to determine the reliability of patient-reported comorbidities and to identify which patient factors influence the reliability. Included studies assessed the reliability of at least one patient-reported comorbidity against their medical record or clinical assessment as gold standard. Twenty-four eligible studies were included in the meta-analysis. Only endocrine diseases (Cohen's Kappa Coefficient (CKC) 0.81 (95% CI 0.76 to 0.85)), consisting of diabetes mellitus (CKC 0.83 (95% CI 0.80 to 0.86)) and thyroid disease (CKC 0.68 (95% CI 0.50 to 0.86)), showed good-to-excellent reliability. Factors most frequently reported to influence concordance included age, sex and educational level. This systematic review demonstrated poor-to-moderate reliability for most systems, except for endocrine which showed good-to-excellent reliability. Although patient self-reporting can be a useful guide to clinical management, several patient factors were demonstrated to affect reliability therefore it should be avoided as a standalone measure.

Golf participation after rotator cuff repair: functional outcomes, rate of return and factors associated with return to play.

BACKGROUND: Golf is a popular sport involving overhead activity and engagement of the rotator cuff (RC). This study aimed to determine to what level golfers were able to return to golf following RC repair, the barriers to them returning to golf and factors associated with their failure to return to golf. METHODS: Patients preoperatively identifying as golfers undergoing RC repair at the study centre from 2012 to 2020 were retrospectively followed up with to assess their golf-playing status, performance and frequency of play and functional and quality of life (QoL) outcomes. RESULTS: Forty-seven golfers (40 men [85.1%] and 7 women [14.9%]) with a mean age of 56.8 years met the inclusion criteria, and 80.1% were followed up with at a mean of 27.1 months postoperatively. Twenty-nine patients (76.3%) had returned to golf with a mean handicap change of +1.0 (P=0.291). Golf frequency decreased from a mean of 1.8 rounds per week preinjury to 1.5 rounds per week postoperatively (P=0.052). The EuroQol 5-dimension 5-level (EQ-5D-5L) index and visual analog scale (EQ-VAS) score were significantly greater in those returning to golf (P=0.024 and P=0.002), although functional outcome measures were not significantly different. The primary barriers to return were ipsilateral shoulder dysfunction (78%) and loss of the habit of play (22%). CONCLUSIONS: Golfers were likely (76%) to return to golf following RC repair, including mostly to their premorbid performance level with little residual symptomatology. Return to golf was associated with a greater QoL. Persistent subjective shoulder dysfunction (78%) was the most common barrier to returning to golf. Level of evidence: Level IV.

The Radiographic Union Score for ulnar fractures (RUSU) predicts ulnar shaft nonunion.

AIMS: To develop a reliable and effective radiological score to assess the healing of isolated ulnar shaft fractures (IUSF), the Radiographic Union Score for Ulna fractures (RUSU). METHODS: Initially, 20 patients with radiographs six weeks following a non-operatively managed ulnar shaft fracture were selected and scored by three blinded observers. After intraclass correlation (ICC) analysis, a second group of 54 patients with radiographs six weeks after injury (18 who developed a nonunion and 36 who united) were scored by the same observers. RESULTS: In the initial study, interobserver and intraobserver ICC were 0.89 and 0.93, respectively. In the validation study, the interobserver ICC was 0.85. The median score for patients who united was significantly higher than those who developed a nonunion (11 vs. 7, p < 0.001). A ROC curve demonstrated that a RUSU ≤ 8 had a sensitivity of 88.9% and specificity of 86.1% in identifying patients at risk of nonunion. Patients with a RUSU ≤ 8 (n = 21) were more likely to develop a nonunion (n = 16/21) than those with a RUSU ≥ 9 (n = 2/33; OR 49.6, 95% CI 8.6-284.7). Based on a PPV of 76%, if all patients with a RUSU ≤ 8 underwent fixation at 6 weeks, the number of procedures needed to avoid one nonunion would be 1.3. CONCLUSION: The RUSU shows good interobserver and intraobserver reliability and is effective in identifying patients at risk of nonunion six weeks after fracture. This tool requires external validation but may enhance the management of patients with isolated ulnar shaft fractures.

Factors associated with failure of fixation of Vancouver B fractures around a cemented polished tapered stem: A 5 to 14 year follow up study.

AIMS: There is increasing evidence for fixation as opposed to revision for Vancouver B fractures around polished taper slip stems, however it is remains unclear whether fixation is associated with stem loosening in the longer term. This study aims to assess survival of plate-fixation of Vancouver-B-fractures around a polished-taper- slip cemented stem and identify factors associated with failure. METHODS: Retrospective cohort study assessed 129 consecutive unilateral Vancouver-B-fractures around cemented Exeter stems at a minimum of 5 years following open-reduction-internal-fixation (ORIF) with unilateral non-locked unilateral plating+/-cerclage cables. The primary outcome measure was reoperation for any reason. Kaplan Meier survival analysis was performed. RESULTS: Fractures (B1 n = 31 (24%); B2 n = 91 (71%); and B3 n = 7 (5%)) occurred at median of 6 years (IQR 1.2-9.2) after primary surgery. Mean patient age was 78.2 (SD10.56, range 46-96) and 54 (42.9%) were female. Mean follow up was 8.7 years (SD 2.48, 5.7 to 14.4). Symptomatic femoral stem loosening requiring revision occurred in two B2 fractures of metaphyseal split and short spiral patterns. The most common mode of failure was non-union (n = 7, 5%). Both fixation failure (n = 6/31 Vs n = 3/91 vs n = 0/7, p = 0.008) and reoperation (n = 8/31 vs n = 6/91 vs n = 0/7, p = 0.008) were significantly higher following fixation of B1 fractures compared to B2 and B3 fractures. Overall 5year survival free from reoperation was 88.8% (82.0-94.7 95%CI). B1 fracture types were associated with an increase risk of failure (endpoints fixation failure p = 0.010; and reoperation p = 0.016). Transverse fractures (B1) were associated with a relative risk of reoperation of 4.22 (1.63-10.9 95% CI, p = 0.008). CONCLUSION: Fixation of Vancouver-B fractures around cemented Exeter stems, when the bone-cement interface is intact and the fracture is anatomically reducible, had an excellent 5-year survival. Only 2 (1.6%) cases of late femoral stem loosening occurred, however, B1 type transverse fractures were associated with a higher rate of reoperation.

Can Arthroplasty Stem Influence Outcome: A Randomized Controlled Trial of Stem Length in Cemented Total Hip Arthroplasty.

BACKGROUND: The primary aim was to assess whether a short (125 millimeter (mm)) stem offered an equivalent hip-specific function compared to the standard (150 mm) stem when used for cemented total hip arthroplasty. Secondary aims were to evaluate health-related quality of life, patient satisfaction, stem height and alignment, as well as radiographic loosenings and complications between the two stems. METHODS: A prospective twin-center double-blind randomized control trial was conducted. During a 15-month period, 220 patients undergoing total hip arthroplasty were randomized to either a standard (n = 110) or a short (n = 110) stem. There were no significant (P ≥ .065) differences in preoperative variables between the groups. Functional outcomes and radiographic assessment were undertaken at a mean of 1 and 2 years. RESULTS: There were no differences (P = .428) in hip-specific function according to the mean Oxford hip scores at 1 year (primary endpoint) or at 2 years (P = .622) between the groups. The short stem group had greater varus angulation (0.9 degrees, P = .003) when compared to the standard group and were more likely (odds ratio 2.42, P = .002) to have varus stem alignment beyond one standard deviation from the mean. There were no significant (P ≥ .083) differences in the forgotten joint scores, EuroQol-5-Dimension, EuroQol-visual analogue scale, short form 12, patient satisfaction, complications, stem height, or radiolucent zones at 1 or 2 years between the groups. CONCLUSION: The cemented short stem used in this study had equivalent hip-specific function, health-related quality of life, and patient satisfaction when compared to the standard stem at mean 2 years post operation. However, the short stem was associated with a greater rate of varus malalignment, which may influence future implant survival.

Surgical Versus Nonsurgical Management of Humeral Shaft Fractures: A Systematic Review and Meta-Analysis of Randomized Trials.

INTRODUCTION: The aim was to compare surgical and nonsurgical management for adults with humeral shaft fractures in terms of patient-reported upper limb function, health-related quality of life, radiographic outcomes, and complications. METHODS: MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, PubMed, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, International Clinical Trials Registry, and OpenGrey (Repository for Grey Literature in Europe) were searched in September 2021. All published prospective randomized trials comparing surgical and nonsurgical management of humeral shaft fractures in adults were included. Of 715 studies identified, five were included in the systematic review and four in the meta-analysis. Data were extracted by two independent reviewers according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. Methodological quality was assessed using the revised Cochrane risk-of-bias tool for randomized trials. Pooled data were analyzed using a random-effects model. RESULTS: The meta-analysis comprised 292 patients (mean age 41 [18 to 83] years, 67% male). Surgery was associated with superior Disabilities of the Arm, Shoulder and Hand (DASH) and Constant-Murley scores at 6 months (mean DASH difference 7.6, P = 0.01; mean Constant-Murley difference 8.0, P = 0.003), but there was no difference at 1 year (DASH, P = 0.30; Constant-Murley, P = 0.33). No differences in health-related quality of life or pain scores were found. Surgery was associated with a lower risk of nonunion (0.7% versus 15.7%; odds ratio [OR] 0.13, P = 0.004). The number needed to treat with surgery to avoid one nonunion was 7. Surgery was associated with a higher risk of transient radial nerve palsy (17.4% versus 0.7%; OR 8.23, P = 0.01) but not infection (OR 3.57, P = 0.13). Surgery was also associated with a lower risk of reintervention (1.4% versus 19.3%; OR 0.14, P = 0.04). CONCLUSIONS: Surgery may confer an early functional advantage to adults with humeral shaft fractures, but this is not sustained beyond 6 months. The lower risk of nonunion should be balanced against the higher risk of transient radial nerve palsy. LEVEL OF EVIDENCE: Level I.

Preoperative Anemia Is Associated With Worse Joint-Specific Postoperative Outcomes, but Is Not Associated With Health-Related Quality of Life or Patient Satisfaction After Total Knee Arthroplasty.

BACKGROUND: The primary aim assessed whether preoperative anemia was associated with a worse knee-specific functional outcome after total knee arthroplasty (TKA). The secondary aims assessed the association of preoperative anemia with generic health and patient satisfaction. METHODS: A retrospective cohort study was undertaken to compare patients who did and did not have anemia (Hb <13.0 g/dL for men and Hb <11.5 g/dL for women). During a 1-year period, 497 patients underwent a total knee arthroplasty with complete preoperative and postoperative data, including 215 (43.3%) men and 282 (56.7%) women, who had a mean age of 70 years (range 45-93). Patient demographics, comorbidities, preoperative and postoperative (1 year) Oxford Knee Score (OKS), EuroQol 5 dimension (EQ-5D), postoperative Forgotten Joint Score (FJS), and patient satisfaction were collected. Regression analyses were used to adjust for confounding factors between the groups. RESULTS: The 56 (11.3%) patients who had anemia were older (4.6 years, P < .001) and more likely to have chronic obstructive pulmonary disease (P = .004), connective tissue (P = .047), or kidney disease (P = .011) compared to those who did not have anemia. There were no differences in the preoperative OKS (P = .752) or EQ-5D (P = .762) scores between the groups. When adjusting for confounding differences, there was a significantly lower postoperative OKS (-3.0 points, P = .035) and FJS (-11.6 points, P = .011) associated with the anemia group. There were no significant differences in the EQ-5D (P = .118) or patient satisfaction between groups (odds ratio 0.84, P = .976). CONCLUSION: Preoperative anemia is associated with a lower postoperative joint-specific functional outcome. It is not clear if these differences are clinically meaningful. No difference in patient satisfaction was observed. LEVEL OF EVIDENCE: Level III, diagnostic study.

Tear size, general health status and smoking influence functional outcome at 5 years following arthroscopic rotator cuff repair.

Introduction: There is limited medium-term outcome data regarding the predictors of functional outcome and patient satisfaction after arthroscopic rotator cuff repair. Methods: 287 patients that underwent arthroscopic rotator cuff repair under a high-volume single surgeon were contacted at a minimum of 4 years following surgery. Patient demographics, tear size and co-morbidities were pre-operatively recorded. The Oxford shoulder score, EuroQol 5-dimensional score and patient satisfaction were recorded at final follow-up. Results: 234 (81.5%) patients completed follow-up at a mean of 5.5 (4-9) years. There were 126 males and 108 females with a mean age of 60 (range 25-83) years. The majority of patients (n = 211, 90%) were satisfied with their final outcome. Multivariate linear regression analysis (R 2 = 0.64) identified that increasing tear size (p = 0.04), worsening general health assessed by the EuroQol 5-Dimensional (p < 0.001), and smoking (p = 0.049) were associated with a worse Oxford shoulder score. Logistic regression analysis (R 2 = 0.13) identified that worsening general health assessed by the EuroQol 5-Dimensional (p < 0.001), and smoking (p = 0.01) were associated with an increased risk of patient dissatisfaction. Conclusion: General health status and smoking are independent predictors of functional outcome and patient satisfaction at medium-term follow-up following arthroscopic rotator cuff repair.

COVID-19 during the index hospital admission confers a 'double-hit' effect on hip fracture patients and is associated with a two-fold increase in 1-year mortality risk.

PURPOSE: The aims were to: (1) determine 1-year mortality rates for hip fracture patients during the first UK COVID-19 wave, and (2) assess mortality risk associated with COVID-19. METHODS: A nationwide multicentre cohort study was conducted of all patients presenting to 17 hospitals in March-April 2020. Follow-up data were collected one year after initial hip fracture ('index') admission, including: COVID-19 status, readmissions, mortality, and cause of death. RESULTS: Data were available for 788/833 (94.6%) patients. One-year mortality was 242/788 (30.7%), and the prevalence of COVID-19 within 365 days of admission was 142/788 (18.0%). One-year mortality was higher for patients with COVID-19 (46.5% vs. 27.2%; p < 0.001), and highest for those COVID-positive during index admission versus after discharge (54.7% vs. 39.7%; p = 0.025). Anytime COVID-19 was independently associated with 50% increased mortality risk within a year of injury (HR 1.50, p = 0.006); adjusted mortality risk doubled (HR 2.03, p < 0.001) for patients COVID-positive during index admission. No independent association was observed between mortality risk and COVID-19 diagnosed following discharge (HR 1.16, p = 0.462). Most deaths (56/66; 84.8%) in COVID-positive patients occurred within 30 days of COVID-19 diagnosis (median 11.0 days). Most cases diagnosed following discharge from the admission hospital occurred in downstream hospitals. CONCLUSION: Almost half the patients that had COVID-19 within 365 days of fracture had died within one year of injury versus 27.2% of COVID-negative patients. Only COVID-19 diagnosed during the index admission was associated independently with an increased likelihood of death, indicating that infection during this time may represent a 'double-hit' insult, and most COVID-related deaths occurred within 30 days of diagnosis.
