Abstract
There is conflicting literature suggesting that intra-articular corticosteroid injections before total knee arthroplasty (TKA) may lead to an increase in the rate of postoperative complications, specifically periprosthetic joint infection (PJI). Thus, this retrospective review of all TKAs performed at a large, urban hospital will add valuable evidence to help guide future patient care. After exclusion criteria, we retrospectively reviewed 417 patients who received a TKA from a group of fellowship-trained orthopaedic surgeons between 2009 and 2016 at a single academic medical center. Minimum follow-up time was 1 year. Patients were separated into two groups: those who received a preoperative intra-articular corticosteroid injection and those who did not receive an injection. Subgroups were created based on the timing of their most recent preoperative injection: 0 to 3 months, 3 to 6 months, 6 to 12 months, 12+ months, and an unknown time period. Postoperative outcomes for PJI, revision TKA, and manipulation under anesthesia (MUA) were analyzed via a Chi-square test. No statistically significant postoperative differences were observed between groups: PJI (p = 0.904), revision TKA (p = 0.206), and MUA (p = 0.163). The temporal subgroups also failed to demonstrate a statistically significant result: PJI (p = 0.348), revision TKA (p = 0.701), and MUA (p = 0.512). This study revealed no absolute or temporal association between preoperative, intra-articular corticosteroid injections, and complications after TKA. Because these injections are a commonly used treatment modality prior to TKA, further studies should be conducted on a nationwide basis to draw more concrete conclusions.

Fourth-Generation Ceramic Head Fracture in Dual Mobility Total Hip Arthroplasty: A Case Report. J Orthop Case Rep 2022; 12:98-101. [PMID: 35611291 PMCID: PMC9091388 DOI: 10.13107/jocr.2022.v12.i01.2638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 11/17/2021] [Indexed: 11/23/2022] Open
Abstract
INTRODUCTION Rare cases of Biolox® delta ceramic head fractures in ceramic-on-polyethylene bearings have been reported in the literature. Virtually none of these catastrophic injuries have been documented in dual mobility constructs. CASE REPORT We report a case of fourth-generation delta ceramic head fracture 4.5 years after implantation in a dual mobility total hip replacement constructs as a result of a ground-level fall. The patient underwent revision arthroplasty with another delta ceramic dual mobility construct and was able to return to work in custodial services 2 weeks after the revision procedure. CONCLUSION In summary, we presented an extremely uncommon case of a fractured fourth generation, Biolox® delta ceramic head in a dual mobility total hip arthroplasty (THA), as a result of a ground-level fall. The patient underwent successful revision surgery to another dual mobility delta ceramic THA. Despite substantial advances in ceramic materials, catastrophic failure of 4th generation ceramic head components can still occur even in dual mobility constructs and require revision arthroplasty surgery.

Aerobic capacity and fatigability are associated with activity levels in women with hip osteoarthritis. J Orthop Res 2021; 39:1236-1244. [PMID: 32918488 PMCID: PMC7952466 DOI: 10.1002/jor.24856] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 08/01/2020] [Accepted: 09/08/2020] [Indexed: 02/04/2023]
Abstract
Physical activity is important for physical function and pain relief in people with lower extremity osteoarthritis (OA). Unfortunately, people with OA are not as active as their peers without OA. The objective of this study was to determine whether aerobic capacity and fatigability are associated with physical activity in women with hip OA. We conducted a cross-sectional analysis of 36 women with hip OA. We assessed aerobic fitness as predicted VO2 max from a 6-min walk test. We assessed fatigability using a treadmill test. Finally, we assessed self-reported physical activity using the UCLA activity scale and quantified steps per day and activity intensity using accelerometers. We used Pearson correlations to determine associations. We used regression analysis to determine whether fatigability mediated the association between aerobic fitness and physical activity. On average, subjects were moderately active via the UCLA score (5.2 ± 1.3 out of 10). Aerobic fitness (R = 0.582, p < .001) and fatigability (R = 0.516, p =.003) were significantly correlated with UCLA scores. However, aerobic fitness was the best predictor of UCLA scores, as well as sedentary time, and time spent in light activity. Fatigability was not a mediator between aerobic fitness and UCLA scores. Aerobic fitness and fatigability may be modifiable barriers to physical activity in people with OA. Future interventional studies should examine whether improving aerobic fitness improves physical activity or fatigability.

Static and dynamic abductor function are both associated with physical function 1 to 5 years after total hip arthroplasty. Clin Biomech (Bristol, Avon) 2019; 67:127-133. [PMID: 31103962 DOI: 10.1016/j.clinbiomech.2019.05.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2018] [Revised: 04/06/2019] [Accepted: 05/08/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND A subset of total hip arthroplasty patients experience functional impairments past the first postoperative year. Poor hip abductor function is common before and in the early postoperative period. It is not known if abductor impairment is associated with long-term functional impairment. This study evaluated the relationships between static and dynamic abductor function and performance-based and self-reported function >1 year post-total hip arthroplasty. METHODS Eighteen adults 1-5 years post-total hip arthroplasty participated. Static and dynamic abductor function were assessed through dynamometry and gait analysis, respectively. Subjects completed four physical performance tests and two self-report instruments. FINDINGS Higher peak isometric abductor strength was associated with better performance-based function (P ≤ 0.001-0.030) and with self-reported function (P ≤ 0.001-0.012). Higher peak external adduction moment was associated with better results on 3 of 4 performance tests (P = 0.007-0.026). Together, static and dynamic abductor function predicted 35-77% of the variation in physical function. Abductor strength best predicted walking test results and self-reported function, while dynamic abductor function best predicted tests involving sit-to-stand INTERPRETATION: Static and dynamic abductor function were associated with physical function 1-5 years after total hip arthroplasty. These results support further investigation of interventions targeting abductor function for persons experiencing persistent impairments.

Arthroscopic Lysis of Adhesions With Manipulation Under Anesthesia Versus Manipulation Alone in the Treatment of Arthrofibrosis After TKA: A Matched Cohort Study. Orthopedics 2019; 42:163-167. [PMID: 31099882 DOI: 10.3928/01477447-20190424-08] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Accepted: 02/21/2019] [Indexed: 02/03/2023]
Abstract
Arthrofibrosis following total knee arthroplasty (TKA) is a debilitating complication. Treatment options include physical therapy, manipulation under anesthesia (MUA), and arthroscopic lysis of adhesions (ALOA) with or without MUA. The authors studied 70 patients with arthrofibrosis after TKA treated with MUA or ALOA plus MUA. In this matched cohort study, 35 patients were treated with MUA and 35 patients were treated with ALOA plus MUA. Total knee arthroplasty followed by MUA was performed by 2 surgeons and TKA followed by MUA plus ALOA was performed by 1 surgeon at 1 institution. Electronic records were used to collect information and match cohorts based on age, sex, body mass index, diabetes mellitus, perioperative range of motion (ROM), and timing of the procedure for arthrofibrosis. The combination of MUA and ALOA yielded changes in ROM: a 72.7% increase 4 to 12 weeks after index TKA (P=.032), a 50.0% increase 12+ weeks after TKA (P=.032), and a 99.8% increase in patients with a pre-manipulation ROM of 0° to 60° (P=.001). Manipulation under anesthesia yielded a 49.2% increase 4 to 12 weeks after TKA (P=.161), a 27.0% increase 12+ weeks after TKA (P=.161), and a 68.8% increase in patients with pre-manipulation ROM of 0° to 60° (P=.084). Patients treated with ALOA plus MUA had greater increases in ROM (P=.026) and final knee flexion (P=.028) compared with those treated with MUA alone. Arthrofibrosis following TKA is a complication that often requires additional procedures. Traditionally, ALOA is added 3+ months from index TKA, when abundant scar formation has occurred. This study found a benefit to ALOA plus MUA compared with MUA alone, with the largest benefit in patients whose pre-manipulation ROM was 0° to 60°. [Orthopedics. 2019; 42(3):163-167.].

Duration of symptoms is associated with conditioned pain modulation and somatosensory measures in knee osteoarthritis. J Orthop Res 2019; 37:136-142.

Abstract
Impaired descending pain inhibition has been linked to chronic pain and poorer patient outcomes. Vibration perception threshold (VPT) has also been observed and linked to radiographic stage of OA. However, it is not known how duration of symptoms may influence these neurophysiological measures. Our purpose was to evaluate the relationship between duration of symptoms and conditioned pain modulation (CPM), a measure of descending pain inhibition, and VPT, and to determine whether these relationships differed in men and women seeking orthopedic care. We evaluated 18 men and 27 women with moderate to severe knee OA. We assessed CPM using a submaximal-effort tourniquet test: Pressure pain threshold (PPT) at the symptomatic knee was evaluated before and after a noxious stimulus. CPM impairment was indicated by a ratio of pre-to-post stimulus PPT ≥1. VPT was assessed using a biothesiometer at the medial femoral condyle. We used chi-square, t-tests and Pearson correlations to address study questions. 72% of men, but only 44% of women had CPM impairment. Duration of symptoms was associated with CPM impairment in women (R = 0.566, p = 0.003) but not men (R = 0.366, p = 0.135). Duration of symptoms was also associated with VPT in both men (R = 0.580, p = 0.012) and women (R = 0.406, p = 0.039). These results suggest that longer duration of knee OA may predict more severe pain sensitization and that important sex differences exist in descending pain inhibition in people with chronic knee OA that may affect disease and course of treatment in male and female patients. © 2018 Orthopaedic Research Society.

Hip abductor strength and fatigue are associated with activity levels more than 1 year after total hip replacement. J Orthop Res 2018; 36:1519-1525.

Abstract
Despite improvements in pain and function, people who undergo total hip arthroplasty (THR) may not always return to desired levels of physical activity (PA). The factors associated with low activity levels are not fully understood. Abductor weakness and fatigue have both been proposed as factors that limit activity in older adults or people with hip osteoarthritis, but have not been investigated after THR. We hypothesized that abductor weakness and fatigue are associated with lower activity levels in people who have undergone a THR and that fatigue mediates the association between abductor strength and activity. We evaluated 16 subjects (24 ± 10 months post-THR; age 56.8 ± 8.4 yrs; BMI 31 ± 7 kg/m2 ). Fatigue was assessed using the PROMIS fatigue short-form 7a. Peak isometric hip abductor torque was assessed using a dynamometer with subjects in a sidelying position. We assessed activity level using the UCLA activity score. We used Pearson correlations to explore the associations among the variables. Next we used a three-step linear regression procedure to test whether or not fatigue acted as a mediator between abductor torque and UCLA activity scores. Higher abductor torque was associated with less fatigue (R2 = 0.275; p = 0.037) and with higher UCLA scores (R2 = 0.488, p = 0.003). Higher fatigue was associated with lower UCLA scores (R2 = 0. 307, p = 0.017), however there was no evidence of mediation. This suggests that addressing both abductor strength and fatigue may increase physical activity. Statement of Clinical Significance: Fatigue and abductor weakness should be evaluated in sedentary THR patients presenting for long-term follow-up. © 2017 Orthopaedic Research Society.

Abstract
The rate of total knee arthroplasty (TKA) utilization in younger patients (< 65 years old) is increasing. Little is known regarding demographics and in-hospital outcomes in this population. The National Hospital Discharge Survey (NHDS) database was searched using International Classification of Diseases, Ninth Revision (ICD-9) procedure codes for patients admitted to U.S. hospitals for unilateral primary TKA between 2001 and 2010. Patients were separated into young (< 65 years of age) and senior cohorts (≥ 65 years of age). ICD-9 diagnosis and procedure codes were used to identify demographics, hospital length of stay, in-hospital adverse events, mortality, and discharge disposition. Trends were evaluated by linear regression with Pearson correlation coefficient (r) and statistical comparisons were made using Student t-test and chi-square analysis. The young cohort accounted for 38.4% of TKAs performed from 2001 to 2005, increasing to 42.7% of TKAs from 2006 to 2010. They had a higher percentage of males (36.4 vs. 34.2%, p < 0.001). Rates of obesity (11.1 vs. 6.0%, p < 0.001) and morbid obesity (5.8 vs. 1.9%, p < 0.001) were significantly higher, yet they had less comorbidities (4.7 vs. 5.2, p < 0.001), and lower rates of transfusion (12.2 vs. 19.8%, p < 0.001), pulmonary embolism (PE) (0.31 vs. 0.49%, p < 0.020), and mortality (0.03 vs. 0.18%, p < 0.001). Patients < 65 years old undergoing TKA have almost double the rate of obesity of patients ≥ 65 years old. This could explain the higher rates of periprosthetic infection and aseptic mechanical failure seen in younger patients. However, the young cohort had a more favorable discharge disposition and lower mortality and risk of PE than elderly patients.

Heightened flexor withdrawal response in individuals with knee osteoarthritis is modulated by joint compression and joint mobilization. THE JOURNAL OF PAIN 2009; 11:179-85.

Abstract
UNLABELLED Patients with chronic pain often present with hyperalgesia, possibly due to hyperexcitability of nociceptive pathways. The aim of the present study was to investigate alterations in flexor withdrawal reflex (FWR) excitability in individuals with knee osteoarthritis (OA) and the potential effect of specific physical inputs or therapeutic interventions (ie, joint compression and mobilization) on these behaviors. Ten subjects with and 10 without knee OA (age 45-75) were recruited. The FWR was examined utilizing suprathreshold, noxious electrocutaneous stimuli applied at the medial foot. Surface electromyographic (EMG) was recorded from the tibialis anterior (TA) and biceps femoris (BF), and peak joint torques recorded at the hip, knee, and ankle. FWR threshold was ascertained and responses at 2x threshold recorded after the following conditions: a maximal, volitional, joint-compression task, a sham hands-on intervention, and a Grade III oscillatory joint-mobilization intervention. A decreased threshold-to-flexor withdrawal response was found in the OA vs control group (P < .01). EMG and joint-torque FWR responses were further augmented in the OA group following the maximal joint-compression task (P < .05), yet remained unchanged or diminished in controls. Joint mobilization, but not sham intervention, reduced reflex responses significantly, although primarily by decreasing BF activity and knee torques (P < .05). PERSPECTIVE Application of specific physical inputs to individuals with knee OA similar to those encountered during activity of daily living or during therapeutic interventions appear to modulate involuntary, nociceptive reflex responses. Routine weight-bearing activities such as walking may potentially enhance heightened FWR responses, while joint mobilization, a commonly used clinical intervention, may diminish reflex excitability.

Abstract
Seventy-four patients (120 knees, 360 injections) referred to an orthopedic surgery clinic by their primary care physician for osteoarthritis knee pain received 3 weekly intra-articular injections of hylan G-F 20 (Synvisc; Genzyme Biosurgery, Ridgefield, NJ). Osteoarthritic knee pain, the ability to perform activities, and the amount of pain medication, physiotherapy, and assistive device use were prospectively evaluated 1 month and 1 year after treatment. The majority of patients reported improved or much improved pain at 1 month (99%) and 1 year (91%) after hylan G-F 20 therapy. Patient activity was similarly improved in the majority of patients at 1 month (99%) and 1 year (69%) following physiotherapy. Of the 120 knees treated with hylan G-F 20, pain relief >6 months was reported for 62% of knees. Use of analgesics, nonsteroidal anti-inflammatory drugs, intra-articular steroids, physiotherapy, and assistive devices was reduced with hylan G-F 20 for 75%-100% of patients at 1 month, and was sustained at 1 year in the majority of patients (78%-94%) for the use of analgesics, steroids, and physiotherapy. Three (4%) patients experienced erythema and irritation at the injection site that resolved within 48 hours and did not interfere with the remaining injections. Hylan G-F 20 effectively and safely relieves osteoarthritis knee pain, facilitates an improved activity level, and decreases the need for pain medication, physiotherapy, and assistive devices.

Abstract
The use of arthrodesis to salvage failed total knee arthroplasty is reviewed in nine patients. Prosthetic failure was due to infection in six cases, aseptic loosening in two cases, and instability in one case. The techniques of arthrodesis included six Hoffman external fixators, two fluted intramedullary rods (3M-Orthopedic Products Division, St Paul), and one pulsing electromagnetic field stimulator. Arthrodesis was successful in eight of nine patients, averaging 5.4 months to union. All eight patients resumed a painfree functional level of activity. Meticulous surgical technique and appropriate method of arthrodesis are emphasized.

Abstract
In a retrospective study of total hip replacement (THR) arthroplasty in patients with renal transplants, femoral head avascular necrosis (AVN) was found in 19 of 138 (15%) patients. Nine THRs in eight of these 19 patients (average age, 47 years) were studied. Preoperatively, all patients had hip pain due to AVN and a history of long-term treatment with systemic corticosteroids. Six of the eight patients had been treated with parenteral pulsed steroids on three occasions, and the other two patients on one occasion, for rejection episodes. All patients showed some degree of femoral head collapse roentgenographically. There were no major surgical complications. All patients had markedly improved functional capacities and relief of pain. With follow-up averaging three years, there has been no evidence of component loosening.
