Intelligent rehabilitation assistant system to promote the early functional recovery of the elderly patients with femoral neck fracture after hemiarthroplasty (HA): A protocol for a randomized controlled trial.

BACKGROUND: Femoral neck fracture is a common type of hip fracture, which has a high morbidity and mortality. Surgical treatment is the first choice. However, the functional rehabilitation after operation has not been paid enough attention. In addition, the quality of exercise is difficult to quantify, and the rehabilitation is lack of standards. Therefore, the intelligent rehabilitation assistant system which could record exercise details, might be used to evaluate the quality and adherence to the prescribed exercise to this fragile group of patients has great relevance, so as to provide new ideas for postoperative rehabilitation of hip fracture. METHODS: This is an opening, prospective, double-dummy RCT. Fifty femoral neck fractures patients, older than 65 years and are about to hospitalize for HA, will be invited to study. The sample will be divided into monitoring group and control group randomly at a 1:1 ratio. The prescribed exercises need to be done continuously for 2 weeks. The monitoring group needs additional use intelligent rehabilitation assistant system. Each subject will receive a total of 4 follow-up visits at the designated time (2 weeks, 4 weeks, 12 weeks, and 24 weeks). The following factors will be talked as dependent variables:Each subject will receive a total of 4 follow-up visits at the designated time, and the findings will be analyzed statistically considering a 5% significance level (P < .05). DISCUSSION: Exercise under monitor may improve patients compliance and exercise quality, and accelerate the rehabilitation process. This protocol reported in accordance with the CONSORT 2010 checklist and SPIRIT 2013 Checklist. TRIAL REGISTRATION: The trial is registered at Chinese Clinical Trials Registry (ChiCTR2000033213, May 24, 2020).

The American Society of Shoulder and Elbow Therapists' consensus statement on rehabilitation for anatomic total shoulder arthroplasty.

Anatomic total shoulder arthroplasty is the gold standard shoulder replacement procedure for patients with an intact rotator cuff and sufficient glenoid bone to accommodate prosthetic glenoid implant and offers reliable patient satisfaction, excellent implant longevity, and a low incidence of complications. Disparity exists in the literature regarding rehabilitation strategies following anatomic total shoulder arthroplasty. This article presents a consensus statement from experts in the field on rehabilitation following anatomic total shoulder arthroplasty. The goal of this consensus statement is to provide a current evidence-based foundation to inform the rehabilitation process after anatomic total shoulder arthroplasty. These guidelines apply to anatomic total shoulder arthroplasty (replacement of the humeral head and glenoid), hemiarthroplasty (replacing only the humeral head), and hemiarthroplasty with glenoid reaming or resurfacing. The consensus statement integrates an extensive literature review, as well as survey results of the practice patterns of members of the American Society of Shoulder and Elbow Therapists and the American Shoulder and Elbow Surgeons. Three stages of recovery are proposed, which initially protect and then gradually load soft tissue affected by the surgical procedure, such as the subscapularis, for optimal patient outcomes. The proposed guidelines should be used in collaboration with surgeon preferences and patient-specific factors.

Hemiarthroplasty in a patient with femoral neck fracture and pyoderma gangrenosum: a case report and review of the literature.

BACKGROUND: Pyoderma gangrenosum is a rare ulcerating skin disease of unknown etiology, making its coincidence with orthopedic trauma a rare challenge. Patients are at risk of progression of the existing lesions and development of new lesions upon skin injury when surgical procedures are performed. To our knowledge, this is the first report in the literature of disease unrelated surgery during active pyoderma gangrenosum. CASE PRESENTATION: We present a case of femoral neck fracture in a Caucasian patient with concurrent pyoderma gangrenosum localized in the axilla. Hemiarthroplasty was safely performed after disease activity was reduced with systemic corticosteroids. Tissue-protective wound closure was used together with perioperative corticosteroids and antibiotics. No signs of pyoderma gangrenosum developed at the surgical wound site, and the axillary lesions showed constant improvement until healing with scar tissue. CONCLUSIONS: In our patient, the preoperative steroid treatment, perioperative antibiotics, and soft tissue protective surgical technique led to successful management of this rare coincidence.

Post-discharge use of assistive devices following hemiarthroplasty: comparison of fracture patients with or without hip precautions.

Purpose: To describe which types of assistive devices prescribed and actually used, either due to precautions or due to true functional reasons, after hip fracture-related hemiarthroplasty.Materials and methods: About 394 patients cluster-randomized 2010-2014 at a university hospital. Control group with standard postoperative precautions to reduce dislocations, mandatory assistive devices and knee brace for 6 weeks (in cognitively impaired) compared to non-precaution group with assistive devices only if needed. Postal questionnaire at 6 weeks and 3 months.Results: Both prescription and usage of reacher were higher in the precaution group. About 55% of patients with precautions was instructed to use stocking aids, 21% continued to do so. Significantly fewer without precautions, 11%, used it at 3 months. Raised toilet seat was used by ∼40% of all pre-fracture and was prescribed to 79% with precautions. It was unchanged at 42% in non-precaution group. Nevertheless, 64% in non-precaution group used a raised toilet both at 6 weeks and 3 months. The usage persisted around 70% in precaution group. Usage of raised chair/bed were similar, even if non-precaution patients was not prescribed such. In the precaution group, 102 were prescribed a knee brace, only 5 used it at 6 weeks.Conclusions: The use of assistive devices did not follow what was prescribed from the hospital, regardless of precautions or not. The use of higher furniture was similar regardless of precautions or not. Other devices were more common in the precaution group. The compliance of knee bracing was low, and bracing should not be standard-of-care.Implications for rehabilitationHemiarthroplasty is the most common treatment of displaced femoral neck fracture in elderly. Dislocation occur in 2 to 10% of these patients, and traditionally patients have been instructed to be careful when moving their leg and to use a number of assistive devices, in order to reduce the dislocation risk.The evidence base for such precautions is weak and occupational therapy and assistive devices may be costly. The current study shows that prescriptions and instructions from occupational therapists in hospital is more or less not follow after dismissal.Assistive devices should be prescribed based on the hip fracture patient's true functional needs, and not routinely or due to arthroplasty precautions.

Hip fracture-great steps forward but we still need better evidence. A commentary on NICE CG124 and QS16 on fractured neck of femur.

The National Institute for Health and Care Excellence (NICE) updated its Clinical Guideline and its Quality Standard on hip fracture in 2017. Three quality statements relate to the organisation of care-having a multidisciplinary hip fracture programme, and both operating and starting rehabilitation without delay-while three relate to surgical aspects, the most recent being the requirement to offer total hip replacement rather than hemiarthroplasty for those with displaced intracapsular fractures who could mobilise outdoors with a stick. Some evidence exists to support this, but the timely provision of this more complex and specialised operation presents a logistical challenge to many units. The evidence for many more general aspects of the care of hip fracture patients is still extrapolated from other populations, and more research is needed to guide the care of this specific group.

Functional and clinical outcomes of patients aged younger and older than 85 years after rehabilitation post-hip fracture surgery in a co-managed orthogeriatric unit.

AIM: Literature investigating rehabilitation outcomes after hip surgery among individuals aged ≥85 years is sparse. We compared the characteristics and outcomes of patients aged under and over 85 years, and assessed factors potentially associated with rehabilitation success as described by the Barthel Index (BI). METHODS: From 2011 to 2014, we prospectively enrolled 328 patients (n = 152 aged <85 years, n = 176 aged ≥85 years) admitted to an orthogeriatric unit (Sondrio, Italy) with a diagnosis of hip fracture requiring surgical treatment. We excluded patients who were being treated conservatively. Outcomes included absolute functional gain (AFG; BI at discharge - BI on admission), rehabilitation effectiveness index (AFG / length of stay) and postoperative complications. RESULTS: Older patients were more functionally (mean BI on admission: 11.7 ± 9.6 vs 16.4 ± 12.2, P < 0.001) and cognitively impaired than their younger counterparts (34.1% vs 18.4%, P < 0.001). Surgery time (1.9 ± 1.2 vs 2.3 ±1.3 days, P = 0.008) and length of stay were shorter for older patients (5.7 ± 2.1 vs 6.6 ± 2.4 days, P < 0.001). There were no differences in terms of complications. Patients aged <85 years showed better functional outcomes (BI, AFG, REI) at discharge than patients aged ≥85 years (mean AFG: 38.2 ± 24.2 vs 26.1 ± 22.0, P < 0.001). BI on admission (OR 1.05, 95% CI 1.02-1.08) and cognitive impairment (OR 0.58, 95% CI 0.34-0.98) were independently associated with rehabilitation outcomes, regardless of chronological age. CONCLUSIONS: Both groups (aged <85 and ≥85 years) showed a significant functional improvement at discharge. Older patients show a residual ability to recover after surgery. A high rehabilitation efficiency - regardless of age - should be pursued even for the oldest old patients experiencing hip fracture. Geriatr Gerontol Int 2018; 18: 1194-1199.

Alanine aminotransferase blood levels and rehabilitation outcome in older adults following hip fracture surgery.

Low alanine aminotransferase (ALT) blood levels are associated with frailty and poor outcome in older adults. Therefore, we studied the association between ALT blood levels before rehabilitation and rehabilitation outcome in older adults following hip fracture surgery. A total of 490 older adults (age>60 years, mean age: 82.9±6.7 years, 82.0% women) admitted to rehabilitation following hip fracture surgery were included. The rehabilitation outcome was assessed by Functional Independence Measure (FIM) scores. ALT blood levels were documented between 1 and 6 months before rehabilitation. Patients with ALT blood levels over 40 IU/l possibly consistent with liver injury were excluded. The cohort was divided into two groups: patients with ALT more than 10 IU/l and patients with ALT less than or equal to 10 IU/l. Upon rehabilitation discharge, the FIM outcome measures (motor, cognitive, gain, efficiency) were significantly higher in patients with ALT more than 10 IU/l relative to patients with ALT less than or equal to 10 IU/l (P<0.05). A logistic regression analysis adjusted for age and sex showed that patients with ALT more than 10 IU/l were more likely to have higher (second to fourth upper quartiles) total FIM scores (>50), cognitive FIM scores (>16), and FIM efficiency (>0.228) upon rehabilitation discharge (odds ratio=1.56-1.78). However, this association was no longer significant following adjustment also for admission total FIM score, cognitive impairment, cancer, and albumin serum levels. High-normal ALT blood levels before rehabilitation are associated with a better rehabilitation outcome in older adults following hip fracture surgery. It may be used when data on admission FIM score, cognitive impairment, cancer, and albumin serum levels are not available.

Return to sport after shoulder arthroplasty: a systematic review and meta-analysis.

PURPOSE: With increasing incidence and indications for shoulder arthroplasty, there is an increasing emphasis on the ability to return to sports. The main goal of this study was to determine the rate of return to sport after shoulder arthroplasty. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to perform this systematic review and meta-analysis. A search was performed on MEDLINE, Scopus, EMBASE, and the Cochrane Library. The quality of the included studies was evaluated according to the Methodological Index for Nonrandomized Studies checklist. The main judgement outcome was the rate of return to sports activity after shoulder arthroplasty and the level of play upon return (identical or higher/lower level). RESULTS: Thirteen studies were reviewed, including 944 patients (506 athletes), treated with shoulder arthroplasty at an average follow-up of 5.1 years (range, 0.5-12.6 years). The most common sports were swimming (n = 169), golf (n = 144), fitness sports (n = 71), and tennis (n = 63). The overall rate of return to sport was 85.1% (95% CI, 76.5-92.3%), including 72.3% (95% CI, 60.6-82.8%) returning to an equivalent or improved level of play, after 1-36 months. Patients undergoing anatomic total shoulder arthroplasty returned at a significantly higher rate (92.6%) compared to hemiarthroplasty (71.1%, p = 0.02) or reverse total shoulder arthroplasty (74.9%, p = 0.003). CONCLUSION: Most patients are able to return to one or more sports following shoulder arthroplasty, with anatomic total shoulder arthroplasty having the highest rate of return. LEVEL OF EVIDENCE: IV.

A comparison of treatment setting for elderly patients with hip fracture, is the geriatric ward superior to conventional orthopedic hospitalization?

INTRODUCTION: Hip fractures in the elderly are a major cause of morbidity and mortality. The treatment settings of these patients may change their outcomes. The aim of this study is to compare the outcomes of patients with displaced femoral neck fractures who were admitted to the orthopedic vs. geriatric wards. PATIENTS AND METHODS: A retrospective study was conducted on 217 consecutive older patients with 219 displaced femoral neck fractures admitted either to the orthopedic or the geriatric ward between Jan. 2013 and Jun. 2015. Information regarding demographic, medical history, surgical management, hospitalization, and one year readmissions and mortality data was retrieved from electronic charts. RESULTS: 102 hemiarthroplasty patients were admitted to the orthopedic ward and 117 to the geriatric ward. Patients' characteristics, including age, living arrangements, mobility status and the Charlson Comorbidity Index were similar between groups. Patients from the orthopedic ward had shorter hospitalization time (9±5.1 vs. 10.8±6.7days, p=0.022) and presented a lower in-hospital complication rates (0.6±0.96 vs. 1±1.9, p=0.022), namely fewer events of urinary retentions, urinary tract infections and pneumonias (8.8% vs. 23.9%, p=0.004, 3.9% vs. 14.5%, p=0.010 and 2.9% vs. 12.2%, p=0.034, respectfully). Readmission rates were similar. Neither in hospital nor one year mortality rates differed between groups. CONCLUSIONS: Our study found that geriatric care was not superior to orthopedic directed management in the treatment of elderly patients with hip fractures in terms of in-hospital complications, and hospitalization times.

Return to sports and work after partial shoulder replacement surgery.

BACKGROUND: Shoulder hemiarthroplasty is a particularly attractive treatment option in young active patients, where revision surgery is an issue and a glenoid replacement might be necessary in the long run. These patients often ask about the possibility of returning to sport and work after surgery. OBJECTIVE: The purpose of this investigation was to analyze whether patients undergoing shoulder hemiarthroplasty (HSA) are able to successfully return to sports activities and work after surgery. MATERIALS AND METHODS: This study included 42 patients treated with HSA. Two subgroups were built: patients who had participated in sports less than 5 years prior to surgery (group A: n = 29, 69%) and those who had not done so (group B: n = 13, 31%). Evaluation was based on a questionnaire asking about types of sports, frequency of sports activity, and the time taken to return to sports and work, as well as about limitations in occupational life. RESULTS: Patients' mean age at the time of surgery was 56.3 ± 12.7 years in group A and 66.9 ± 13.8 years in group B. Mean follow-up was 5.5 years (range 2.5-12 years). In group A, 18 patients (62%) had participated in sports up to the time of surgery and 12 (41%) had returned to the same level of sports activity at final follow-up. The rate of return to preoperative sports activity was 67%. Swimming was one of the most favorable sports (92%). Of the cohort patients, 2 (5%) had to change their profession due to surgery. Most patients were retired at follow-up. CONCLUSION: Patients who were sportingly active prior to HSA were able to return to sports after surgery in 67% of cases. This study confirms that patients treated by hemiarthroplasty of the shoulder joint can return to sports and work, even at medium-term follow-up.

Radiological Decision Aid to determine suitability for medial unicompartmental knee arthroplasty: development and preliminary validation.

AIMS: An evidence-based radiographic Decision Aid for meniscal-bearing unicompartmental knee arthroplasty (UKA) has been developed and this study investigates its performance at an independent centre. PATIENTS AND METHODS: Pre-operative radiographs, including stress views, from a consecutive cohort of 550 knees undergoing arthroplasty (UKA or total knee arthroplasty; TKA) by a single-surgeon were assessed. Suitability for UKA was determined using the Decision Aid, with the assessor blinded to treatment received, and compared with actual treatment received, which was determined by an experienced UKA surgeon based on history, examination, radiographic assessment including stress radiographs, and intra-operative assessment in line with the recommended indications as described in the literature. RESULTS: The sensitivity and specificity of the Decision Aid was 92% and 88%, respectively. Excluding knees where a clear pre-operative plan was made to perform TKA, i.e. patient request, the sensitivity was 93% and specificity 96%. The false-positive rate was low (2.4%) with all affected patients readily identifiable during joint inspection at surgery. In patients meeting Decision Aid criteria and receiving UKA, the five-year survival was 99% (95% confidence intervals (CI) 97 to 100). The false negatives (3.5%), who received UKA but did not meet the criteria, had significantly worse functional outcomes (flexion p < 0.001, American Knee Society Score - Functional p < 0.001, University of California Los Angeles score p = 0.04), and lower implant survival of 93.1% (95% CI 77.6 to 100). CONCLUSION: The radiographic Decision Aid safely and reliably identifies appropriate patients for meniscal-bearing UKA and achieves good results in this population. The widespread use of the Decision Aid should improve the results of UKA. Cite this article: Bone Joint J 2016;98-B(10 Suppl B):3-10.

Cross-cultural validation of the Italian version of the Cumulated Ambulation Score.

Hip fractures are common in elderly patients, and walking impairment is a frequent complication. The Cumulated Ambulation Score (CAS) is a validated functional scale used to monitor easily three basic mobility activities in patients with hip fracture. The aim of this study was to translate, cross-cultural adapt, and validate the CAS in the Italian language (CAS-I). The translation was carried out according to recommended guidelines. The final version of the CAS-I was administered to 80 geriatric patients with hip fracture admitted to a Traumatology Unit, and allowed full weight-bearing after treatment with hemiarthroplasty. Two raters evaluated each patient 2 days after surgery and then after 3 months. Statistical methods included Cronbach's α coefficient for the scale's internal consistency; the total agreement; and the κ coefficient for the inter-rater reliability. The concurrent validity of the scale was determined by comparing the total CAS-I (0-6 points) with the Index of Independence in Activities of Daily Living score (0-4 points). Internal consistency and inter-rater reliability of the CAS, evaluated with Cronbach's α and κ, respectively, were above 0.84 and 0.94. The SE of measurement for the total CAS-I (0-6 points) 2 days and 3 months after surgery were 0.03 and 0.13 points, respectively. The CAS-I showed a significant correlation with the first four items of the Activities of Daily Living score scale (r≥0.85, P<0.001). This study confirms the validity of the CAS-I for patients with a hemiarthroplasty after hip fracture and provides additional evidence of the psychometric properties of the scale. We suggest that the official CAS-I version be used in other settings to evaluate the basic mobility in patients with hip fracture.

Enhanced recovery programme reduces opiate consumption in hip hemiarthroplasty.

INTRODUCTION: The enhanced recovery programme (ERP) is used to improve patient experience before, during and after an operation. Initially designed for colorectal surgery, it has now been adopted by many other disciplines, including orthopaedics. Where applicable, ERP has shown to be associated with less pain, reduced length of hospital stay and increased patient satisfaction in elective orthopaedic procedures. There is, however, a paucity of data regarding the use of ERP in fractured neck of femur (NOF) operations. Our aim was to investigate the effect of ERP on analgesic requirements and hospital length of stay during hemiarthroplasty. METHOD: Consecutive notes of 100 patients who received a hemiarthroplasty for a fractured NOF were reviewed retrospectively. In one group (n = 50), patients received routine pre- and post-operative care; the second (n = 50) were on the ERP. All patients were previously mobile with an abbreviated mental test score of more than eight and lived in their own home. RESULTS: With ERP, oral opiate consumption fell dramatically in the first three post-operative days (4.7 vs. 14.0 mg, p > 0.005). The use of patient-controlled analgesia (PCA) was also significantly reduced (odds ratio 0.16, p > 0.05). Although ERP had no statistically significant effect on length of stay (7 vs. 8.5 days, p = 0.2), it saw a greater proportion of patients being discharged back to their own home (25 vs. 19 patients, p < 0.05). CONCLUSION: The ERP reduces post-operative oral opiates and PCA requirements in fractured NOF cases and by inference reduces pain. It does not appear to affect length of hospital stay in an acute unit.

The A-test: assessment of functional recovery during early rehabilitation of patients in an orthopedic ward--content, criterion and construct validity.

BACKGROUND/AIM: The A-test was designed for assessment of functional recovery during early rehabilitation of patients in an orthopedic ward. This performance-based test consists of 10 items for assessing basic activities by a six level ordinal scale (0-5). Total scores can range from 0 to 50, i.e. from inability to perform any activity despite the help of therapists to complete independence and safety in performing all activities. The aim of this study was to examine the A-test validity. METHODS: This prospective study was conducted in an orthopedic ward and included 120 patients [60 patients with hip osteoarthritis that underwent arthroplasty and 60 surgically treated patients with hip fracture (HF)] during early inpatient rehabilitation (1st-5th day). Validity was examined through 3 aspects: content validity--floor and ceiling effect, range, skewness; criterion validity--concurrent validity [correlation with the University of Iowa Level of Assistance Scale (ILAS) for patients with hip osteoarthritis, and with the Cumulated Ambulation Score (CAS) for patients with HF, Spearman rank correlation] and predictive validity [the New Mobility Score (NMS) 4 weeks after surgery, Mann-Whitney U test]; construct validity--4 hypotheses: 1) on the fifth day of rehabilitation in patients underwent arthroplasty due to hip osteoarthritis, the A-test results will strongly correlate with those of ILAS, while the correlation with the Harris hip score will be less strong; 2) in patients with HF, the A-test results will be significantly better in those with allowed weight bearing as compared to patients whom weight bearing is not allowed while walking; 3) results of the A-test will be significantly better in patients with hip osetoarthritis than in those with HF; 4) the A-test results will be significantly better in patients younger than 65 years than in those aged 65 years and older. RESULTS: The obtained results were: low floor (1%) and ceiling (2%) effect, range 0-50, skewness 0.57, strong correlation with ILAS for the patients with hip osteoarthritis (r = -0.97, p = 0.000) and with CAS for the patients with hip fracture (r = 0.91, p = 0.000). The patients with the A-test score 35 and more on the fifth day of rehabilitation (n = 46, Md = 4) had significantly higher NMS rank 4 weeks after surgery than the patients with the A-test score less than 35 (n = 59, Md = 2), (U = 379, z = -6.47, p = 0.000, r = 0.63). All 4 hypotheses were confirmed. CONCLUSION: The A-test is simple and valid instrument for everyday evaluation of pace and degree of functional recovery during early rehabilitation of patients surgically treated in an orthopedic ward.

The A-test--reliability of functional recovery assessment during early rehabilitation of patients in an orthopedic ward.

BACKGROUND/AIM: There are few tests for evaluation of functional abilities of patients surgically treated for hip fractures or osteoarthritis during early rehabilition period. The aim of this study was to investigate reliability (interobserver reproducibility and internal consistency) of the A-test, an original test for functional recovery evaluation during early rehabilitation of patients in an orthopedic ward. METHODS: The investigation included 105 patients (55 patients with hip osteoarthritis that underwent arthroplasty and 50 surgically treated patients with hip fracture). It was conducted in an orthopedic ward during early inpatient rehabilitation (from 1st to 5th day). For their functional recovery evaluation during early rehabilitation we used the A-test, a performance-based test with 10 items for assessing basic activities by six level ordinal scale (0-5). For internal consistency of the test the Cronbach coefficient alpha was calculated for the A-test results collected during early rehabilitation for all patients (105 patients x 5 days = 525 measures) and separately for the results of patients with hip osteoarthritis (275 measures) and hip fracture (250 measures). Values of this coefficient > 0.7 imply good internal consistency of the test. Interobserver reproducibility was estimated as follows: two physiotherapists together conducted physical therapy with the patients, and then, separately, rated the performance of each activity from the test (78 measures). The agreement between their estimations was expressed by the linear weighted kappa coefficient (for very good agreement values of kappa coefficeent have to be in the range 0.81-1). RESULTS: The Cronbach coefficient alpha was 0.98 (the results of all the patients and the results of the patients with hip osteoarthritis) and 0.97 (the results of the patients with hip fracture). The values of kappa coefficient were in the range 0.81-0.92 for all items. CONCLUSION: The A-test is a reliable instrument for everyday evaluation of functional recovery during early rehabilitation of patients surgically treated in an orthopedic ward.

Determinants of revision and functional outcome following unicompartmental knee replacement.

OBJECTIVE: Unicompartmental Knee Replacement (UKR) has important advantages over total knee replacement (TKR) but has a higher revision rate. Outcomes vary between centres, suggesting that risk factors for revision may be modifiable with changes to patient selection or operative technique. The objective of this study was to determine factors affecting revision, patient-reported outcome and satisfaction following UKR. METHOD: 25,982 cases from three national databases were analysed. Multilevel multivariable regression models were used to examine the effect of patient and surgical factors on implant survival, patient-reported outcome and satisfaction at 6 months and 8 years following UKR. RESULTS: Of the 25,982 cases, 3862 (14.9%) had pre-operative and 6-month Oxford Knee Scores (OKS). Eight-year survival was 89.1% (95% confidence intervals (CI) 88.3-89.9). OKS increased from 21.9 (SD 7.6) to 37.5 (SD 9.5). Age (Hazard ratio (HR) 0.96 (95% CI 0.96-0.97) per year), male gender (HR 0.86 (95% CI 0.76-0.96)), unit size (HR 0.92 (95% CI 0.86-0.97) per case up to 40 cases/year) and operating surgeon grade (HR 0.78 (95% CI 0.67-0.91) if consultant) predicted improved implant survival. Older patients (≥ 75 years), and those with lower deprivation levels had superior OKS and satisfaction (adjusted mean difference 0.14 (95% CI 0.09-0.20) points per year of age and 0.93 (95% CI 0.60-1.27) per quintile of deprivation). Ethnicity, anxiety and co-morbidities also affected patient-reported outcome. CONCLUSIONS: This study has identified important predictors of revision and patient-reported outcome following UKR. Older patients, who are least likely to be offered UKR, may derive the greatest benefits. Improved understanding of these factors may improve the long-term outcomes of UKR.

UniCAP as an alternative for unicompartmental arthritis.

Medial tibiofemoral arthrosis is a disabling disease, particularly for active middle-aged patients who have failed conservative and biological precursor treatments. The UniCAP Bipolar Knee Resurfacing System (Arthrosurface, Incorporated, Franklin, Massachusetts) was introduced in 2008 to add a new layer to reconstructive joint surgery, allowing for a delay in traditional joint replacement procedures. It utilizes intraoperative, 3-dimensional joint surface mapping to fit and implant defect-sized components that are matched to the individual joint surface.

Humeral surface replacement for osteoarthritis.

BACKGROUND AND PURPOSE: Humeral resurfacing has shown promising results for osteoarthritis, but revisions for glenoid erosion have been reported frequently. We investigated the hypothesis that preoperative glenoid wear and postoperative progress of glenoid erosion would influence the clinical outcome. METHODS: We reviewed 61 resurfacing hemiarthroplasties (55 patients) for primary osteoarthritis. 6 patients were lost to follow-up and 5 had undergone revision arthroplasty. This left 50 shoulders in 44 patients (mean age 66 years) that were followed for mean 30 (12-44) months. Complications, revisions, and the age- and sex-related Constant score were assessed. Radiographs were evaluated for loosening and glenoid erosion according to Walch. RESULTS: Of the 50 shoulders that were functionally assessed, the average age- and sex-related Constant score was 73%. In patients with preoperative type-B2 glenoids, at 49% it was lower than in type-A1 glenoids (81%, p = 0.03) and in type-B1 glenoids (84%, p = 0.02). The average age- and sex-related Constant score for patients with type-A2 glenoids (60%) was lower than for type-A1 and -B1 glenoids and higher than for type-B2 glenoids, but the differences were not statistically significant. In the total population of 61 shoulders, the radiographs showed postoperative glenoid erosion in 38 cases and no humeral prosthetic loosening. Revision arthroplasty was performed in 11 cases after 28 (7-69) months. The implant size had no statistically significant influence on the functional outcome. The size was considered to be adequate in 28 of the 50 functionally assessed shoulders. In 21 cases, the implant size was too large and in 1 case it was too small. INTERPRETATION: We found frequent postoperative glenoid erosion and a high rate of revision arthroplasty after humeral resurfacing for primary osteoarthritis. Oversizing of the implants was common, but it had no statistically significant influence on the functional outcome. Inferior results were found in the presence of increased eccentric preoperative glenoid wear. Total shoulder arthroplasty should be considered in these patients.

Care pathways in physical and rehabilitation medicine (PRM): the patient after proximal humeral fracture and shoulder hemi-arthroplasty.

This document is part of the "Care Pathways in Physical and Rehabilitation Medicine" series developed by the French Physical and Rehabilitation Medicine Society (Sofmer) and the French Physical and Rehabilitation Medicine Federation (Fedmer). For a given patient profile, each concise document describes the patient's needs, the care objectives in physical and rehabilitation medicine, the required human and material resources, the time course and the expected outcomes. The document is intended to enable physicians, decision-makers, administrators and legal and financial specialists to rapidly understand patient needs and the available care facilities, with a view to organizing and pricing these activities appropriately. Here, patients with acute proximal humeral fracture requiring shoulder hemi-arthroplasty are classified into four care sequences and two clinical categories, both of which are treated according to the same six parameters and by taking account of personal and environmental factors (according to the WHO's International Classification of Functioning, Disability and Health) that may influence patient needs.
