Patient Perspectives Regarding Healthcare Professional Attire.

Introduction Physician attire has been shown to influence patients' impression of their healthcare provider. Scrubs and formal office attire are interchangeably worn by physicians. This study aimed to determine differences in scrubs and formal office attire on patient perceptions of professionalism, friendliness, aptitude, and empathy. Methods A single-center questionnaire study was conducted and a total of 150 patients were included. Patients were recruited from the inpatient and outpatient settings. Patients completed a questionnaire in which they rated 22 photographs. The photographs comprised a series of randomly arranged vignettes, with each participating physician appearing twice - once in formal office attire, once in scrubs. The physicians served as their own controls. Patients were asked to rate the depicted physicians based on the following four criteria - professionalism, friendliness, aptitude, and empathy. Each criterion was rated on an 11-point scale (0-10). Comprehensive demographic information, including age, gender, and race, was collected. Results A total of 150 responses were collected (50 inpatient and 50 orthopaedic surgery outpatient, 50 general medicine outpatient). Scrubs were rated significantly higher than formal office attire in all domains: professionalism [mean 7.52 (SD 1.95) vs. 6.69 (SD 2.38), p< 0.001], friendliness [mean 7.54 (SD 1.86) vs. 6.87 (SD 2.23), p< 0.001], aptitude [mean 7.44 (SD 1.99) vs. 6.72 (SD 2.36), p < 0.001] and empathy [mean 7.36 (SD 2.01) vs. 6.71 (SD 2.36), p < 0.001]. The perceived age of the physician did not affect any of the domain scores. Female physicians scored poorer in professionalism [mean 6.95 (SD 2.30) vs. 7.20 (SD 2.16), p < 0.05] compared to male physicians, but this difference resolved when analyzing only physicians wearing Scrubs.  Conclusion Patients view physicians in scrubs as having higher professionalism, friendliness, aptitude, and empathy as compared to physicians in formal office attire. Physicians should don standardized colored scrubs with a prominent name tag to improve patient perceptions.

Multidirectional instability of the shoulder: a systematic review with a novel classification.

Purpose: A variety of instabilities are grouped under multidirectional instability (MDI) of the shoulder. This makes understanding its diagnostic process, presentation and treatment difficult due to lack of evidence-based consensus. This review aims to propose a novel classification for subtypes of MDI. Methods: A systematic search was performed on PubMed Medline and Embase. A combination of the following 'MeSH' and 'non-MesH' search terms were used: (1) Glenohumeral joint[tiab] OR Glenohumeral[tiab] OR Shoulder[tiab] OR Shoulder joint[tiab] OR Shoulder[MeSH] OR Shoulder joint[MeSH], (2) Multidirectional[tiab], (3) Instability[tiab] OR Joint instability[MeSH]. Sixty-eight publications which met our criteria were included. Results: There was a high degree of heterogeneity in the definition of MDI. Thirty-one studies (46%) included a trauma etiology in the definition, while 23 studies (34%) did not. Twenty-five studies (37%) excluded patients with labral or bony injuries. Only 15 (22%) studies defined MDI as a global instability (instability in all directions), while 28 (41%) studies considered MDI to be instability in two directions, of which one had to include the inferior direction. Six (9%) studies included the presence of global ligamentous laxity as part of the definition. To improve scientific accuracy, the authors propose a novel AB classification which considers traumatic etiology and the presence of hyperlaxity when subdividing MDI. Conclusion: MDI is defined as symptomatic instability of the shoulder joint in two or more directions. A comprehensive classification system that considers predisposing trauma and the presence of hyperlaxity can provide a more precise assessment of the various existing subtypes of MDI. Level of Evidence: III.

Repair of Massive Rotator Cuff Tear With Medialization and Balloon Spacer Insertion.

Retracted massive rotator cuff tears can be challenging to repair. Reduction of the retracted tendon to the native footprint may result in a repair with excessive tension. Repair under excessive tension predisposes to increased tendon retear rates. Footprint medialization involves securing the tendon medial to the anatomic footprint, resulting in decreased tension during repair. Several surgical adjuncts can also be employed to reinforce such tears so as to reduce the risk of retear. The aim of this Technical Note is to describe a surgical technique of rotator cuff repair with medialization of the footprint combined with a balloon spacer insertion.

3D-printed patient specific surgical guides: Balancing accuracy with practicality.

Introduction: Three-dimensional (3D) printing technology has been used in orthopaedic surgery in recent years to manufacture customized surgical cutting jigs. However, there is scarcity of literature and information regarding the optimal parameters of an ideal jig. Our study aims to determine the optimum parameters to design surgical jigs that can produce accurate cuts, and remain practical for use, to serve as a guide for jig creation in future. Methods and materials: A biomechanical lab study was designed to investigate whether the thickness of a jig and the height of its cutting slot can significantly affect cutting accuracy. Surgical jigs were 3D printed in medical grade, and an oscillating sawblade was used to mimic intraoperative surgical cuts through the cutting slots onto wooden blocks, which were then analysed to determine the accuracy of cuts. Results: Statistical analysis was performed on a total of 72 cuts. The cutting accuracy increased when the thickness of the jig increased, at all slot heights. The cutting accuracy also increased as the slot height decreased, at all jig thicknesses. Overall, the parameters for jig construction that yielded the most accurate cuts were a jig thickness of 15 mm, in combination with a slot height of 100 % of the width of the sawblade. Additionally, at a jig thickness of 15 mm, there was no statistically significant difference in cutting accuracy when increasing the slot height to 120 %. Conclusion: This study is the first to propose tangible parameters that can be applied to surgical jig construction to obtain reproducible accurate cuts. Provided that a jig of 15 mm thickness can be accommodated by the size of the wound, the ideal surgical jig with a superior balance of accuracy and useability is 15 mm thick, with a cutting slot height of 120 % of the sawblade thickness.

The segond fracture: A narrative review of the anatomy, biomechanics and clinical implications.

The Segond fracture is commonly regarded as pathognomonic for significant intra-articular pathology such as an anterior cruciate ligament (ACL) tear. There is worsened rotatory instability in patients with concomitant ACL tear and Segond fracture. Current evidence does not suggest that a concomitant and unrepaired Segond fracture leads to worst clinical outcomes after ACL reconstruction. However, there remains a lack of consensus on several aspects of the Segond fracture such as its exact anatomical attachments, ideal imaging modality for detection and indication for surgical treatment. There is currently no comparative study evaluating the outcomes of combined ACL reconstruction and Segond fracture fixation. More research is necessary to deepen our understanding and establish consensus on the role of surgical intervention.

Aspiration of a Large Acromioclavicular Joint Cyst Complicated by Recurrence and Enlargement: A Case Report.

This case report describes a patient with an enlarging and painless lump over the right acromioclavicular joint (ACJ). MRI showed a synovial cyst superior to the ACJ with a concomitant full-thickness tear of the supraspinatus. The patient underwent needle aspiration of the lump, which yielded 100ml of gelatinous fluid with no microbe growth. Despite repeated aspirations, the ACJ cyst continually enlarged beyond its initial size. This case report describes an ACJ cyst that enlarged in size after needle aspiration. The authors suggest surgical alternatives if cyst recurrence is observed after the initial attempt of aspiration.

Does laterality matter? a systematic review and meta-analysis of clinical and survival outcomes of medial versus lateral meniscal scaffolds.

PURPOSE: Meniscal scaffold implants have gained interestas a therapeutic alternative for irreparable partial meniscal defects and post-meniscectomy syndrome. However, the effect of laterality on outcomes is unclear. This study aimsto assess the hypothesis that lateral meniscal scaffold implants have worse clinical or survival outcomes compared with medial scaffold implants. METHODS: The study was performedaccording to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and registered with PROSPERO. Three databases (PubMed, Embase, Scopus) were searched from date of database establishment to 21 January 2022. Human studies reporting clinical or survival outcomedata specific to the medial or lateral meniscal scaffold implant were included. Random-effects model was used to analyse survival outcome data. RESULTS: Ten studies comprising 568 patients (mean age 29.2-40 years, follow up duration 1-14 years) were included. There were 483 medial and 85 lateral meniscal scaffold implants. Amongst two studies directly comparing the survival rate of medial and lateral meniscal scaffolds, there was no significant difference in survival rates between medial and lateral meniscus scaffolds (hazard ratio = 1.24, 95 % confidence interval: 0.51-3.03, P = 0.63). There were no consistent statistically significant differences between medial and lateral meniscal scaffolds in terms of postoperative Visual Analog Scale pain,Tegner Activity, Lysholm, International Knee Documentation Committee, Knee Injury and Osteoarthritis Outcome, and Knee Society Scores. CONCLUSION: Despite anatomical and biomechanical differences between the medial and lateral meniscus, there are no significant differences in clinical outcomes or survival rates between medial and lateral meniscal scaffold implants for irreparable partial meniscal defects at short- or mid-term follow up. Lateral meniscal scaffold implants are therefore non-inferior to medial meniscal scaffold implants.

Outcomes of ultra-old vs old patients after hip fracture surgery: a matched cohort analysis of 1524 patients.

BACKGROUND: Surgical management of geriatric hip fractures yields improved functional outcomes with decreased morbidity and mortality. Cohort studies have suggested that the older patients within the geriatric age group have worse outcomes with surgery, However, these studies inherently report inflated risks due to poor handling of confounders and have inadequately age-stratified their geriatric population. AIM: This study aims to investigate the effect of age alone on the 1-year mortality and functional status of geriatric patients after hip fracture surgery. METHODS: This is a retrospective single institution cohort study based on the prospectively-maintained registry of hip fracture patients. 2603 patients aged 60 years and above were treated surgically under a geriatric-orthopaedic hip fracture pathway from January 2014 to December 2018. Patients were split into two age groups: ultra-old (≥ 85 years) vs old (< 85 years). Baseline demographics and the ASA (American Society of Anaesthesiologists) status and the Modified Barthel's Index (MBI) were obtained at admission and 1 year after the fracture. Adverse outcomes from the fracture and surgery were recorded during a follow-up period of minimally 2 years. A 2:1 matching process based on the gender, fracture type, ASA status, CCI and MBI categories was conducted. RESULTS: There were 1009 and 515 patients in the old and ultra-old age groups, respectively. 1-year mortality was similar for both age groups (4.0% ultra-old vs 3.6% old, p = 0.703). 30-day morbidity was similar except for higher rates of postoperative pneumonia in the ultra-old (14.0 vs 6.3%, p < 0.001). MBI scores at 1-year were lower in the ultra-old (severe dependence: 16.4 vs 10.0%; p = 0.001). Ultra-old patients were less likely to be community ambulant at 12 months (21.2 vs 36.0%) with the deterioration in ambulatory status significant after correction for baseline status (p < 0.001). CONCLUSION: The 1-year mortality of surgically-managed geriatric hip fracture patients older than 85 years of age is not determined by age alone. Patients aged 85 years and above are at higher risk for pneumonia postoperatively. Ultra-old hip fracture patients with an intertrochanteric fracture are more likely to have poorer function at 1 year after hip fracture surgery.

Anterior cruciate ligament rupture and associated Segond fracture: Incidence and effect on associated ligamentous and meniscal injuries.

Introduction: The Segond fracture is an avulsion fracture of the lateral tibial plateau and is widely considered to be pathognomonic of anterior cruciate ligament (ACL) rupture. In addition to ACL rupture, Segond fractures have also been noted to be associated with significant intra-articular pathology such as meniscal injuries as well as extra-articular pathology such as collateral ligament injuries. This is likely due to the fact that the presence of a Segond fracture may represent increased rotatory instability. Whilst several studies have demonstrated the association of a Segond fracture with significant intra-articular pathology, there is a paucity of literature assessing if the combination of an ACL rupture and Segond fracture gives rise to higher rates of concomitant ligamentous and meniscal injuries. The primary objective of this study is to determine if patients with ACL ruptures associated with Segond fractures have higher rates of concomitant ligamentous and meniscal injury, when compared to patients with ACL ruptures without a Segond fracture. Methods: A retrospective review of all patients who underwent ACL reconstruction in a single institution between 2014 to 2018 was conducted. A review of the patients' demographics, operative notes, and radiographs was performed. X-rays and MRI scans were double-read by a board-certified radiologist and Orthopaedic surgeon. Results: A total of 414 subjects were included. The incidence of Segond fracture was 2.4%. The mean age was 24.7±7.4 (range 16 to 60) years and 26.7±7.6 (range 16 to 38) years in patients with and without Segond fractures respectively. 89.9% of patients suffered a non-contact mechanism of injury, with sports injuries being most common (79.5%). There was a significantly higher rate of isolated lateral meniscus tears in patients with Segond fractures compared to those without (50% v.s. 20.8%) based on pre-operative MRI. (p<0.05) There were no other significant differences in associated ligamentous injuries. Conclusion: The incidence of Segond fracture associated with ACL rupture is 2.4%. There is a significantly higher risk of a concomitant isolated lateral meniscus tear in ACL ruptures associated with a Segond fracture. There is no significantly higher risk of concomitant ligamentous injuries in ACL ruptures associated with a Segond fracture.

Glenoid Component Placement Assisted by Augmented Reality Through a Head-Mounted Display During Reverse Shoulder Arthroplasty.

Component positioning is a key factor for avoiding complications and improving functional outcomes in reverse shoulder arthroplasty. Preoperative planning can improve component positioning. However, translating the preoperative plan into the surgical procedure can be challenging. This is particularly the case for the glenoid component positioning in severe deformity or limited visualization of the scapula. Different computational-assisted techniques have been developed to aid implementation of the preoperative plan into the surgical procedure. Navigated augmented reality (AR) refers to the real world augmented with virtual real-time information about the position and orientation of instruments and components. This information can be presented through a head-mounted display (HMD), which enables the user to visualize the virtual information directly overlaid onto the real world. Navigated AR systems through HMD have been validated for shoulder arthroplasty using phantoms and cadavers. This article details a step-by-step guide use of a navigated AR system through HMD, in the placement of the glenoid bony-augmented component.

Effectiveness of anabolic steroids in improving outcomes for post-operative hip fracture patients: A randomized controlled trial.

Background: Post-operative elderly hip fracture patients require significant rehabilitation. Nandrolone is an anabolic steroid used to promote muscle growth. This study aims to examine the effect of nandrolone in improving rehabilitation and quality of life in elderly female patients with hip fractures undergoing hemiarthroplasty. Methods: This is a double-blinded prospective randomized-controlled-trial consisting of female patients above the age of 65 with an isolated neck of femur fracture planned for a hip hemiarthroplasty. Participants were randomized into two arms of the study - 50 mg intramuscular nandrolone vs normal saline placebo administered on post-operative day 0, and weeks 2, 6 and 12. The participants were followed up across a 1-year period following the surgery. Clinical outcomes such as time taken to achieve rehabilitation milestones, distance of ambulation and thigh muscle girth, and functional scoring with SF-36 questionnaire were recorded at intervals of 2, 6 and 12 weeks, 6 months and 1 year following the surgery. Results: There were a total of 23 subjects with 11 in the steroid group and 12 in the placebo group. There was no significant difference in demographics and injury patterns between both groups. There was no significant difference for time taken to achieve various rehabilitation milestones and distance of ambulation. SF-36 scores on discharge and at 1-year follow-up mark were comparable. There was no difference in the complication rate between both groups. Conclusion: Intra-muscular Nandrolone after hip surgery in elderly female patients does not result in short to mid-term improved rehabilitation or functional outcomes. Nandrolone did not result in increased short-term complications after hip surgery. Level of evidence: I.

Raised initial total white cell count and lower post-operative decline of C reactive protein increases the risk of secondary surgery in septic arthritis of the native knee.

PURPOSE: Septic arthritis is an orthopaedic emergency with high morbidity and mortality. The aim of this study is to determine the risk factors associated with secondary surgery for septic arthritis of the native knee joint. METHODS: This is a retrospective study reviewing all patients who underwent surgery for septic arthritis of the knee from 2012 to 2019 in a single institution. A total of 117 patients were recruited. Patients were divided into 2 groups: Group I (79/117, 67.5%) underwent one surgery and Group II (38/117, 32.5%) underwent more than one surgery. RESULTS: Patients with a raised initial total white (TW) cell count of > 20 × 109/L had a significantly higher risk of secondary surgery. (Adjusted hazard ratio 2.42, p < 0.05) A decline of CRP level of less than 20% within 24 h from initial operation was also a risk for secondary surgery. (Adjusted hazard ratio 0.34, p < 0.01) Patients in group II also had significantly higher post-operative median TW cell count and neutrophil count. There was no significant difference in the offending microbe, surgical approach, and duration of operation from initial presentation between the groups. CONCLUSIONS: Patients with septic arthritis of the native knee joint who present with raised initial total white cell count of > 20 × 109/L and decline of CRP level of less than 20% within 24 h from initial operation are at higher risk of secondary operation. In these patients, more aggressive treatment strategies and appropriate counselling on the risks of repeated surgery are recommended. LEVEL OF EVIDENCE: Level IV.

Diagnostic thresholds for absolute systolic toe pressure and toe-brachial index in diabetic foot screening.

INTRODUCTION: Identifying peripheral arterial disease (PAD) during diabetic foot screening (DFS) is crucial in reducing the risk of diabetic foot ulcerations and lower limb amputations. Screening assessments commonly used include absolute systolic toe pressure (ASTP) and toe-brachial index (TBI). There is a lack of research defining the threshold values of both assessment methods. We aimed to compare the accuracy of ASTP and TBI and establish optimal threshold values of ASTP and TBI with reference to the internationally accepted ankle-brachial pressure index (ABPI) screening test, for a multiethnic diabetic population in Singapore. METHODS: A retrospective, observational study of DFS results from January 2017 to December 2017 was conducted. Receiver operating characteristic analysis was conducted for ASTP and TBI using the internationally accepted ABPI cut-off value of ≤0.9 to indicate PAD. RESULTS: A total of 1,454 patients with mean (standard deviation) age of 63.1 (12.4) years old were included. There were 50.8% men and 49.2% women, comprising 69.7% Chinese, 13.5% Indian, 10.1% Malay and 6.7% other ethnicities. Areas under the curve for ASTP and TBI were 0.89 (95% confidence interval [Cl] 0.85-0.94) and 0.94 (95% Cl 0.90-0.98), respectively, and the difference was statistically significant (P<0.001). Derived optimal threshold values to indicate ABPI≤0.9 for ASTP and TBI were <95.5mmHg (specificity 0.86, sensitivity 0.84) and <0.7 (specificity 0.89, sensitivity 0.95), respectively. CONCLUSION: ASTP or TBI may be used to detect ABPI-determined PAD in DFS. The optimal threshold values derived from a multiethnic Asian diabetic population were <95.5mmHg for ASTP and <0.7 for TBI.

Capsulolabral Reconstruction During the Open Latarjet Procedure.

Surgical treatment of anterior glenohumeral joint instability can be challenging and carries the inherent risk of recurrent instability, dislocation arthropathy, and postoperative loss of external rotation. In the current manuscript, a technique for combined reconstruction of anterior labrum and capsule, with concomitant reduction of the humeral head during anterior capsule reconstruction in open Latarjet procedure, is presented. Analogous to other techniques, the coracoid graft is fixed on the anteroinferior part of the glenoid between 3 and 5 o'clock. However, for this technique, reattachment of the labrum is performed between the native glenoid and the bone graft. Additionally, during the reconstruction of the anterior capsule on the coracoacromial ligament, while the operated arm is held in external rotation to avoid the postoperative rotational deficit, the humeral head is reduced posteriorly in the center of the glenoid during adduction, slight anterior forward flexion, and a posterior lever push. By doing so, the inherent theoretical risks of persistent instability and dislocation arthropathy are believed to be decreased. Further studies are needed to clarify the long-term consequences of this surgical technique in the clinical setting.

The effect of patient positioning on the accuracy and reliability of assessment of knee range of motion over a telemedicine platform.

INTRODUCTION: Diagnostic accuracy is one of the key considerations of telemedicine usage in orthopedic surgery. The aim of this study was to determine the optimal patient positioning to achieve accurate and reliable visual estimation of the knee joint range of motion over a digital platform for telemedicine. METHODS: A single volunteer was recruited to perform a total of 120 discrete and random knee range of motion angles in three patient positions: sitting, standing and supine. The patient image was broadcast over a digital platform to six raters. The raters recorded their visual estimation of each discrete knee flexion angle independently. After each discrete knee flexion angle, a physical goniometer was used to obtain the actual flexion angle of the knee. RESULTS: A total of 120 discrete measurements (40 measurements in the sitting, standing, and supine positions each) were recorded by each of the six raters. The supine position resulted in the highest intraclass correlation of 0.97 (95% confidence interval: 0.98, 0.99). All three patient positions achieved low absolute difference between the goniometer and the raters with 5.6 degrees (95% limits of agreement: -21.0, 9.8) in sitting, 2.7 degrees (95% limits of agreement: -10.1, 15.4), and 1.2 degrees (95% limits of agreement: -9.8, 12.3) in the supine position. The supine position had the highest accuracy and reliability. DISCUSSION: Visual estimation of the knee joint range of motion over telemedicine is clinically accurate and reliable. Patients should be assessed in a supine position to obtain the highest accuracy and reliability for visual estimation of the knee joint range of motion during telemedicine.

Functional Outcomes of Patients with Schizophrenia After Hip Fracture Surgery: A 1-Year Follow-up from an Institutional Hip Fracture Registry.

BACKGROUND: Schizophrenia impairs a patient's self-care abilities, which are crucial after a hip fracture. Studies on the outcomes of patients with schizophrenia after a hip fracture are dated. This study aims to investigate the complication rates, 1-year mortality, and functional outcomes of surgically managed hip fractures in elderly patients with schizophrenia. METHODS: This is a retrospective, single-institution cohort study based on a prospectively maintained registry of patients with hip fracture. In this study, 3,056 patients who were ≥60 years of age were treated under a geriatric-orthopaedic hip fracture pathway from January 2014 to December 2018. Baseline demographic characteristics and the Modified Barthel Index (MBI) scores were obtained at admission and at 6 months and 1 year after the fracture. Complications from the fracture and the surgical procedure were recorded during a minimum follow-up period of 2 years. A matching process (based on age, sex, and the MBI at admission) of up to 6 patients without schizophrenia per 1 patient with schizophrenia was utilized to increase power. Differences in perioperative, 6-month, and 1-year outcomes were compared for significance among surgically managed patients with schizophrenia and patients without schizophrenia. RESULTS: Thirty-eight patients with schizophrenia were compared with 170 geriatric patients without schizophrenia who underwent a surgical procedure for a hip fracture. Patients with schizophrenia were more likely to be institutionalized postoperatively (26.3% compared with 4.7%; p < 0.001). Patients with schizophrenia had poorer MBI scores at 12 months (76 compared with 90 points; p = 0.006). The 1-year mortality rate was comparable (p = 0.29) between patients with schizophrenia (5.7%) and those without schizophrenia (2.4%). Similar trends in MBI were observed in the conservatively managed group of patients. CONCLUSIONS: There was no increase in postoperative complications after a surgical procedure for a hip fracture in elderly patients with schizophrenia. The 1-year mortality after a surgical procedure for hip fracture is similar in both patients with schizophrenia and those without schizophrenia. Patients with schizophrenia and hip fracture who were surgically managed had poorer 1-year functional outcomes compared with patients without schizophrenia matched for age, sex, and MBI at admission. This information will be useful in shared decision-making discussions with patients and families. LEVEL OF EVIDENCE: Prognostic Level III.

The continuous infusion fascia iliaca compartment block: a safe and effective analgesic modality in geriatric hip fracture patients.

OBJECTIVE: Hip fractures are common orthopaedic injuries in the elderly. Opioids can provide peri-operative pain relief in hip fracture patients, but may have side effects. Peripheral nerve blocks such as the fascia iliaca compartment block (FICB) have become an established part of the multimodal analgesic regime administered peri-operatively to hip fracture patients. We compare the efficacy of the continuous infusion FICB (CFICB) on peri-operative pain relief, opioid usage, its associated complications and the short as well as long term rehabilitation status in geriatric hip fractures patients. MATERIALS AND METHODS: In this retrospective matched case control study, 40 geriatric patients with hip fractures who had received the CFICB from Nov 2014 to April 2016 were matched in a 1:3 ratio with similar patients whom had not received the CFICB from our institution's hip fracture database of 913 patients. RESULTS: A total of 157 patients in both the CFICB group (N = 40) and the control group (N = 117) were studied. The post-operative pain scores and the total opioid consumption during the first 3 days in the CFICB group were significantly less than the control group (p < 0.0001, respectively). The systemic complications in the CFICB group were comparable with the control group. The CFICB group had slower rehabilitation at up to 2 weeks but there was no significant difference at 1 year post surgery in terms of function and mobility between the two groups. In both groups, better pre-fracture function was associated with faster short term rehab outcomes in post-operative patients. CONCLUSION: The CFICB provides safe and effective post-operative pain relief in geriatric hip fracture patients. Post-operative opioid usage is decreased in older hip fracture patients treated with CFICB. Rehabilitation milestones are slower in the short term, but have no significant difference at 1-year post surgery.

Numbness after medial unicompartmental knee arthroplasty: Prevalence and effect on functional outcome.

BACKGROUND: The prevalence of skin sensation alteration after total knee arthroplasty is well established but less so in medial unicompartmental knee arthroplasty (MUKA). The aim of this study was to determine the prevalence, extent of numbness and its effect on mid-term functional outcomes after MUKA. METHODS: A level 2 prospective cohort study was conducted. Twenty patients (21 knees) were recruited. Demographics, length of surgical incision and the thigh-to-calf ratio was recorded. At the 1-year postoperative period, the extent of numbness was measured using a quantifiable grid-based system for both pinprick and fine touch. Preoperative, 3 months and 1 year postoperative Knee Society Scores (KSS) and 36-Item Short Form Health Survey (SF-36) scores were recorded. RESULTS: At the 1-year postoperative period, the prevalence of numbness to both fine touch and pin prick was 58% and 66%, respectively. The mean area of numbness to fine touch and pin prick was 336 mm2 and 521 mm2, respectively. The prevalence and extent of numbness was not significantly associated with surgical factors such as incision length and thigh-to-calf ratio. Prevalence and extent of numbness was not significantly associated with SF-36 scores and KSS at the 1-year postoperative period. CONCLUSIONS: There is a high prevalence of numbness around the knee 1 year after MUKA. Surgical incision length and thigh-to-calf ratio was not associated with the extent of numbness. The presence and extent of numbness did not affect functional outcomes scores at the 1-year postoperative period. This study finding allows for accurate preoperative counselling with regards to numbness and its effects for patients undergoing MUKA.
