Perspectives of Orthopedic Patients on Medical Cannabis: A Survey of More Than 2500 Patients

Nationwide perspectives on cannabis have changed dramatically over recent decades. Although cannabis remains illegal at the federal level, medical cannabis (MC) is now legal in most states, and research has continued to show its effectiveness in a variety of medical conditions. However, both perception and acceptance of MC by the general public are evolving and remain poorly understood. Treating patients effectively with these novel therapeutics requires an understanding of the complex interplay of social and legal factors that could affect patient use. This cross-sectional survey study of more than 2500 patients sought to assess current patient perspectives on MC and to investigate factors related to its use that may represent barriers to broader patient use. Most respondents would consider using MC for chronic pain or other medical conditions. Most respondents were aware of the legal status of MC in their state, and 9 of 10 respondents believed that MC should be legal throughout the United States. General public knowledge of the utility of MC is an area needing improvement because older patients were significantly less likely to believe that MC is safe to use or that MC is safer than prescription opioids. As has been reported in previous literature, social stigma and cost appear to remain barriers for patient use of MC. Our findings provide further insight into current patient perspectives on MC, aiding both medical providers and researchers as we continue to provide access to and research MC.

Hand Surgery Patient Perspectives on Medical Cannabis: A Survey of Over 600 Patients

Purpose

Medical cannabis (MC) has been proposed as a potential addition to multimodal pain management regimens in orthopedics. This study evaluates hand and upper-extremity patient perspectives of MC as a treatment for common orthopedic and musculoskeletal pain conditions. This study also aims to identify the proportion of patients already using MC, perceived barriers to MC use, and opinions on insurance coverage and legality of cannabis.

Methods

An anonymous cross-sectional survey study was conducted of all patients at least 18 years old presenting from October 2020 to January 2021 to a hand and upper-extremity outpatient clinic. The survey collected information regarding opinion on MC, including use, legality, and willingness to use MC in the future. Medical cannabis was legal in the states where the study was conducted.

Results

A total of 679 patients completed the survey (response rate 72.5%). Sixty-eight patients (10.0%) reported currently using MC. Of the 623 patients (90.0%) who reported not currently using MC, 504 (80.9%) would consider using MC for chronic pain, while the remaining 119 (19.1%) would not consider the use of MC for chronic pain. Age was not associated with whether a patient would consider using MC (P = .16) or was already using MC (P = .10). The most identified barrier to MC use was cost, reported as either expensive or not affordable by 477 patients (70.5%).

Conclusions

This study found that most patients presenting for hand and upper-extremity complaints would consider using MC (80.9%), and most perceive it as a safe treatment option for common orthopedic conditions. Moreover, 10% of patients reported already using MC. One of the major barriers to MC use is the cost. Most (90.9%) patients support policies for legalization and insurance coverage of MC.

Decreased flexion contracture after total knee arthroplasty using Botulinum toxin A: a randomized controlled trial

PURPOSE

Flexion contracture after total knee arthroplasty (TKA) can cause significant dissatisfaction. Botulinum toxin A has shown improved extension in patients with spastic flexion contractures after TKA. The purpose of this study was to evaluate whether Botulinum toxin A improves knee extension for any patient with flexion contractures following TKA.

METHODS

A prospective, double-blinded, randomized controlled trial was conducted. Fourteen patients (15 knees), with a flexion contracture (≥10°) one month postoperatively, were randomized to receive either Botulinum toxin A or saline placebo to the affected hamstrings. The subject, surgeon, and administering physiatrist were blinded to the treatment group throughout the study. Subject range of motion (ROM) was evaluated at 1, 6, and 12 months following injection. Differences were tested using mixed-effects regression to control for multiple measurements.

RESULTS

The initial post-operative flexion contracture averaged 19° ± 6° in the Botulinum toxin A group and 13° ± 3° in the saline group. Injections were performed 53 and 57 days after TKA in the Botulinum toxin A and saline groups, respectively. Post-injection extension improved to an average of 8, 5, and 1 degrees for BTX and 4, 2, and 1 degrees for SAL, at 1, 6, and 12 months, respectively, compared to pre-injection extension (p < 0.0001). Improvement in knee extension at 1 year improved 18° ± 7.5° for Botulinum toxin A and 12° ± 2° for saline (p = 0.04). No complications resulted from either injection.

CONCLUSION

Patients who received Botulinum toxin A or placebo were able to achieve near full extension one year after surgery. There was a statistically significant improvement in the amount of extension achieved at 1 year with Botulinum toxin A, but this may be of little clinical significance. Since achieving full extension is important for patient function and satisfaction, novel techniques to address this issue deserve special attention.

Evaluation and nonsurgical management of rotator cuff calcific tendinopathy

Rotator cuff calcific tendinopathy is a common finding that accounts for about 7% of patients with shoulder pain. There are numerous theories on the pathogenesis of rotator cuff calcific tendinopathy. The diagnosis is confirmed with radiography, MRI or ultrasound. There are numerous conservative treatment options available and most patients can be managed successfully without surgical intervention. Nonsteroidal anti-inflammatory drugs and multiple modalities are often used to manage pain and inflammation; physical therapy can help improve scapular mechanics and decrease dynamic impingement; ultrasound-guided needle aspiration and lavage techniques can provide long-term improvement in pain and function in these patients.
