Coinfection of HIV and hepatitis C increases complication rates after total joint arthroplasty

Risk factors for rehospitalization within 90 days in patients with total joint replacement: A meta-analysis

BACKGROUND

The risk factors influencing the readmission within 90 days following total joint replacement (TJR) are complex and heterogeneous, and few systematic reviews to date have focused on this issue.

METHODS

Web of Science, Embase, PubMed, and Chinese National Knowledge Infrastructure databases were searched from the inception dates to December 2022. Relevant, published studies were identified using the following keywords: risk factors, rehospitalization, total hip replacement, total knee replacement, total shoulder replacement, and total joint replacement. All relevant data were collected from the studies that meet the inclusion criteria. The methodological quality of the studies was assessed using the Newcastle-Ottawa Scale (NOS).

RESULTS

Of 68,336 patients who underwent TJR, 1,269,415 (5.4%) were readmitted within 90 days. High American Society of Anesthesiologists (ASA) class (OR, 1.502; 95%CI:1.405-1.605; P < .001), heart failure (OR,1.494; 95%CI: 1.235-1.754; P < .001), diabetes (OR, 1.246; 95%CI:1.128-1.377; P < .001), liver disease (OR, 1.339; 95%CI:1.237-1.450; P < .001), drinking (OR, 1.114; 95%CI:1.041-1.192; P = .002), depression (OR, 1.294; 95%CI:1.223-1.396; P < .001), urinary tract infection (OR, 5.879; 95%CI: 5.119-6.753; P < .001), and deep vein thrombosis (OR, 10.007; 95%CI: 8.787-11.396; P < .001) showed statistically positive correlation with increased 90-day readmissions after TJR, but high blood pressure, smoking, and pneumonia had no significant association with readmission risk.

CONCLUSION

The findings of this review and meta-analysis will aid clinicians as they seek to understand the risk factors for 90-day readmission following TJR. Clinicians should consider the identified key risk factors associated with unplanned readmissions and develop strategies to risk-stratify patients and provide dedicated interventions to reduce the rates of readmission and enhance the recovery process.

Postoperative outcomes of total elbow replacement in haemophilic elbow arthropathy: A systematic review

INTRODUCTION

Total elbow replacement (TER) is a surgical treatment option for haemophilic elbow arthropathy.

AIM

To review the outcomes of TER in haemophilic elbow arthropathy. The primary outcome measures were perioperative blood loss, postoperative complications, revision rates and length of hospital stay (LOS). Secondary outcomes were elbow range of motion (ROM), functional outcome scores and the visual analogue pain scale (VAS).

MATERIALS AND METHODS

PubMed, Medline, Embase and the Cochrane register were searched conforming to the PRISMA guidelines. Only studies with a minimum postoperative follow-up of 1 year were included. Quality appraisal was performed utilizing the MINORS criteria.

RESULTS

One hundred and thirty-eight articles were identified. Following article screening, only seven studies met the inclusion criteria. A total of 51 TERs in 38 patients were performed, with the Coonrad-Morrey prosthesis utilized in 51% of cases. The pooled postoperative complication and revision rates were 49% and 29%, respectively. Surgery-related postoperative mortality was 3.9%. The mean preoperative Mayo elbow performance score (MEPS) was 43 ± 20 whereas the mean postoperative MEPS was 89 ± 6. Mean preoperative VAS was 7.2 ± 1.9 while the mean postoperative VAS was 2.0 ± 1.4. Mean preoperative and postoperative elbow flexion arcs were 54 ± 15 and 91 ± 10 degrees, respectively. Mean preoperative and postoperative forearm rotation arcs were 86 ± 40 and 135 ± 19 degrees, respectively.

CONCLUSION

TER for haemophilic elbow arthropathy provides good to excellent improvements in pain and elbow ROM postoperatively. However, the overall complication and revision rates are relatively high, when compared to TER performed for other indications.

Total Joint Arthroplasty Should Not Be Delayed in Hepatitis C Patients After Successful Treatment Achieving a Sustained Viral Load

Background

Preoperative treatment recommendations and optimal time to perform total joint arthroplasty (TJA) in patients with hepatitis C virus after treatment completion for achieving best outcomes have not been elucidated. We aim to determine (1) if undetectable viral load (UVL) prior to TJA leads to decreased postoperative complication rates, specifically periprosthetic joint infection (PJI), and (2) if delaying TJA after treatment completion has benefit in decreasing PJI.

Methods

A retrospective review of all hepatitis C virus patients undergoing TJA at 3 academic tertiary care centers was conducted. A total of 270 TJAs performed from 2005 to 2019 were included, 125 with positive viral load at the time of surgery. The duration from completion of treatment regimen to TJA was recorded for the UVL cohort. The primary study outcome was PJI at 1-year follow-up. Secondary outcomes included in-hospital complications, mechanical revision TJA rates, and optimal time to TJA upon completion of treatment.

Results

Patients with positive viral load at the time of TJA had longer length of stay (3.9 vs 2.9 days, P < .0001) and a higher PJI rate at 1 year postoperatively (9% vs 2%, P = .02) than UVL patients. There was no difference of in-hospital complications or revision rates for mechanical etiologies. Delaying TJA after achieving a sustained virologic response did not impact PJI rates.

Conclusions

Sustained UVL prior to TJA is critical to minimize PJI irrespective of the treatment regimen utilized. Surgery can be performed with lower complication rates any time after achieving sustained virologic response.

Complications and surgical treatment after pathological fracture associated to HIV secondary disease. A case report

Due to advances in retroviral treatment, human immunodeficiency virus (HIV)-related disease may become chronic and the patient survival has substantially increased. Osteoarticular disease in those patients include multifocal osteonecrosis and its complications. Pain and functional limitation may be due to these complications, frequently underdiagnosed, including pathological fractures. Its prompt management may require a different approach than osteosynthesis. We present a long-term chronic HIV patient with severe pain and limitation. A tibial plateau pathological fracture associated to multifocal osteonecrosis was identified and treated with osteonecrosis debridement and total knee arthroplasty (TKA). Acute periprosthetic joint infection developed and required debridement, antibiotic and implant retention. The contralateral knee, also with multiple osteonecrosis foci, was managed with early TKA. We highlight the importance of timely surgical reconstruction to avoid serious limitation and complications.

Rotator cuff repair in HIV-positive patients ages 65 and older: only slight increase in risk of general postoperative surgical complications

PURPOSE

To examine postoperative complications associated with rotator cuff repair (RCR) in HIV-positive patients ages 65 and older.

METHODS

Data were collected from the Medicare Standardized Analytic Files between 2005 and 2015 using the PearlDiver Patient Records Database. Subjects were selected using Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes. Demographics including age, sex, medical comorbidities, and smoking status were collected. Complications were examined at 7-day, 30-day, and 90-day postoperative time points. Data were examined with univariate and multivariate analyses.

RESULTS

The study included 152,114 patients who underwent RCR, with 24,486 (16.1%) patients who were HIV-positive. Following univariate analysis, patients with HIV were observed to be more likely to develop 7-day, 30-day, and 90-day postoperative complications. However, the absolute risk of each complication was quite low for HIV-positive patients. Univariate and multivariate analysis showed that within 7 days following surgery, patients with HIV were more likely to develop myocardial infarction (OR 2.5, AR 0.1%) and sepsis (OR 2.5, AR 0.04%). Within 30 days, HIV-positive patients were at increased risk for postoperative anemia (OR 2.8, AR 0.1%), blood transfusion (OR 3.3, AR 0.1%), heart failure (OR 2.3, AR 0.8%), and sepsis (OR 2.7, AR 0.1%). Within 90 days, mechanical complications (OR 2.1, AR 0.1%) were increased in the HIV-positive group.

CONCLUSION

Postoperative complications of RCR occurred at increased rates in the HIV-positive group compared to the HIV-negative group in patients ages 65 and older. In particular, increased risk for myocardial infarction, sepsis, heart failure, anemia, and mechanical complications was noted in HIV-positive patients. However, the actual percentage of patients who experienced each complication was low, indicating RCR is likely safe to perform even in older HIV-positive patients. As more older adults living with HIV present for elective orthopedic procedures, the results of the present study may reassure physicians who are considering RCR as an option for patients in this particular population, while also informing providers about potential complications.
