Prevalence of Cannabidiol (CBD) Use in an Outpatient Hand Surgery Clinic
2025
Background:
The aim of this study was to evaluate the prevalence and perceived efficacy of cannabidiol (CBD) products in patients presenting to an orthopedic hand and upper extremity clinic.
Materials and Methods:
New patients seen for an initial surgical consultation between July and December 2022 were surveyed regarding CBD use, pain, and function. Pain was measured with the Numeric Pain Rating Scale (NPRS, 0–10) and function with the Single Assessment Numeric Evaluation (SANE, 0–100). Demographic and clinical factors were collected via chart review.
Results:
A total of 918 patients completed the survey (53% female; mean age 63 years, range 18–97). Joints involved included elbows (106), wrists (335), and hands/fingers (667). Common diagnoses included arthritis (199), tendinopathy (273), and nerve-related conditions (160). Overall, 15% (135/918) reported prior CBD use, and 39% (53/135) perceived pain relief. CBD users were more likely to be female (65% vs 51%; P=0.003), to present with wrist pathology (44% vs 35%; P=0.038), and to have arthritis (36% vs 19%; P<0.001). Compared to non-users, CBD users reported higher pain scores (mean NPRS 6.2 vs 5.1; P<0.001) and lower contralateral function (mean SANE 77.3 vs 87.4; P<0.001).
Conclusions
In this cohort, CBD use was uncommon, and only a minority of users reported subjective benefit. CBD users tended to report higher pain and worse function, particularly in the setting of wrist arthritis. CBD products did not appear to provide measurable objective improvement in pain or function. Further studies are needed to clarify optimal dosing, administration, and potential role in upper extremity care.

Background:
The optimal graft choice for anterior cruciate ligament (ACL) reconstruction (ACLR) in the high-level cutting and pivoting athlete remains controversial. Studies have shown similar outcomes when directly comparing bone-patellar tendon-bone (BPTB) autograft versus quadriceps soft tissue (QST) autograft in the general population. However, no studies have directly compared these 2 grafts in athletes participating in cutting and pivoting sports.
Hypothesis:
It was hypothesized that, compared with BPTB autograft, the QST autograft would result in similar patient-reported outcomes and rates of retear, return to sport, and complications.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
A retrospective review was performed on athletes participating in cutting and pivoting sports (soccer, American football, lacrosse, and basketball) who underwent primary ACLR with either BPTB autograft or QST autograft chosen by the athlete between January 2015 and January 2019. The International Knee Documentation Committee (IKDC) subjective knee evaluation and Lysholm Knee Scoring Scale were used to evaluate patient-reported outcomes. Return-to-sport and complication rates were identified. Descriptive statistics were expressed using Mann-Whitney test or Student t test for continuous variables and the chi-square test for categorical variables.
Results:
A total of 68 athletes (32 QST, 36 BPTB) were included for analysis. The percentage follow-up was 89% (32/36) for the QST autograft group and 86% (36/42) for the BPTB autograft group. The 2-year IKDC score (QST, 90.5 ± 6.6 vs BPTB, 89.7 ± 7.8) and 2-year Lysholm score (QST, 91.3 ± 7.5 vs BPTB, 90.5 ± 8.6) were similar between groups. The percentage of athletes able to return to sport within the follow-up period was also similar (88% vs 83%; P = .63). There were 2 retears requiring revision in the BPTB group (6%) and no retears in the QST group (P = .18). One contralateral ACL rupture occurred in the QST group (3%) and 4 in the BPTB group (11%) (P = .21).
Conclusion:
The QST and BPTB autografts demonstrated similar patient-reported outcomes, return-to-sport rates, and complication rates after primary ACLR at 2-year follow-up. Both autografts appear to be reliable and consistent options for ACLR in the cutting and pivoting athlete.

Exacerbation of Spinal Stenosis Symptoms Following Neuraxial Anesthesia in an Achondroplastic Cesarean Section
2023
We report the case of an achondroplastic female who presented with acute neurologic decline following epidural anesthesia for an elective cesarean section. Achondroplasia presents unique anatomical challenges to anesthesiologists in perioperative management, and cesarean sections are standard for achondroplastic pregnancies. High rates of spinal stenosis and lumbar radiculopathy in this patient population make administration of epidural analgesia technically challenging and may increase the risk of neurologic injury. Ultrasound is an effective means of administering epidural anesthesia for most patients; however, its utility is user-dependent and more challenging for those with obesity and abnormal spinal anatomy, both of which are common in achondroplasia. Cephalic and thoracic anatomical features in achondroplasia can also make general anesthesia challenging. Therefore, preoperative imaging may help guide preoperative planning based on patient anatomy and individual risk factors to reduce the risks of complications in this patient population. This report includes details from the patient’s prenatal care, cesarean section, and 18 months of follow-up.

The purpose of this study was to examine the effect of follow-up time on revision rates of in situ decompression and ulnar nerve transposition for the surgical treatment of cubital tunnel syndrome. A comprehensive literature search was performed to identify prospective and retrospective primary comparison studies assessing the revision rates of in situ decompression and ulnar nerve transposition for the treatment of cubital tunnel syndrome. Meta-regression analyses were used to assess the effect of average study follow-up on the revision rates of both cubital tunnel syndrome treatments. Modeling results were then used to estimate revision rates between decompression and transposition at increasing follow-up times. Sixteen studies including 2,225 patients were included. Average study follow-up time was a statistically significant moderator of revision rates. Model predictions show that in situ decompression operations had an increased risk for revision as compared to ulnar transposition after 48 months of follow-up. In studies with follow-up time ≥48 months, revision rates for in situ decompression (11.9%) were significantly greater than in ulnar transposition (3.2%). In situ decompression for cubital tunnel syndrome is associated with an increased risk of revision surgery as compared to ulnar nerve transposition, particularly when assessed at longer follow-up intervals. The effect of follow-up duration on revision rates demonstrates the need for additional studies to compare outcomes of these operative approaches at follow-up times ≥48 months. This study provides evidence that ulnar nerve transposition may ultimately lead to lower revision rates and demonstrates the need for prospective, randomized trials to corroborate this effect.

Background:
Meniscal root repair can improve patient outcomes significantly; however, several contraindications exist, including arthritic change to the medial or lateral tibiofemoral compartments.
Purpose/Hypothesis:
The purpose of this study was to evaluate the outcomes of meniscal root repair in patients with advanced patellofemoral chondromalacia (PFC). It was hypothesized that the presence of advanced PFC would not significantly affect the postoperative outcomes.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
A retrospective review was conducted of patients who underwent meniscal root repair with at least 2 years of follow-up data. Patients with chondromalacia as determined by arthroscopic visualization (defined as Outerbridge grade 3 or 4) were placed in the PFC group; patients with Outerbridge grade 0 to 2 chondromalacia were placed in the non-PFC group. Outcomes were measured by the Lysholm knee scoring scale and the International Knee Documentation Committee (IKDC) Subjective Knee Form. Clinical outcomes including complications were also recorded. Quantitative data between the groups were analyzed using the 2-tailed independent-samples t test.
Results:
Overall, this study included 81 patients (35 in the PFC group, 46 in the non-PFC group). The mean follow-up times were 25.1 months in the PFC group and 24.8 months in the non-PFC group. In both groups, Lysholm and IKDC scores improved significantly with 24-month Lysholm scores averaging 85.86 in the PFC group and 86.61 in the non-PFC group (P = .62) and 24-month IKDC scores averaging 77.66 for the PFC group and 79.59 for the non-PFC group (P = .45). The cohorts demonstrated similar rates of retear, arthrofibrosis, infection, and progression to total knee arthroplasty.
Conclusion:
The presence of advanced PFC was not associated with inferior outcomes in patients who underwent posterior meniscal root repair, and rates of recurrent tears, postoperative infection, arthrofibrosis, and conversion to total knee arthroplasty were similar between the study groups. These findings suggest that PFC may not significantly alter the results of meniscal root repair and should not be considered an absolute contraindication for this procedure.
