Purpose: The purpose of this study was to identify sex differences in postoperative outcomes and return‐to‐sport rates after fasciotomy for treatment of chronic exertional compartment syndrome (CECS) of the lower leg. It was hypothesised that male CECS patients would have a higher rate of return to sport than female CECS patients. Methods: A retrospective cohort study was conducted involving patients who underwent primary fasciotomy of one to four leg compartments for treatment of CECS at a single centre from 2010 to 2020. Each affected leg was treated as a separate subject. Postoperative outcomes included CECS pain frequency and severity, return to sport and Tegner activity level. Multivariable regression was used to determine if sex was an independent predictor of outcomes after adjusting for demographic and clinical covariates. p < 0.05 were considered significant. Results: Eighty‐one legs (44 M, 37 F) of 47 unique patients (34 of whom had bilateral symptoms) were included with a mean follow‐up time of 51.5 ± 31.4 months. Male subjects were older (p < 0.001) and had higher body mass index (p < 0.001) compared to female subjects. Most subjects (84.0%) underwent two‐ or four‐compartment fasciotomies. Female sex was found to be predictive of lower overall postoperative pain severity (p = 0.007), higher odds of return to sport (p = 0.04) and higher postoperative Tegner score (p = 0.005). However, female sex was not predictive of postoperative pain frequency, odds of reoperation or odds of return to sport to at least the presymptomatic level (all p < 0.05). Conclusion: Female sex is independently predictive of reduced overall pain severity, higher odds of return to sport and higher postoperative improvement in Tegner score following fasciotomy for treatment of lower‐limb CECS.

Purpose Methods Results Conclusion Level of Evidence The aim of this study was to assess the inter‐rater reproducibility and inter‐method comparability of hip alpha angle measurements on magnetic resonance imaging (MRI)/magnetic resonance arthrography (MRA) and plain radiographs in patients with femoroacetabular impingement syndrome (FAIS).A cross‐sectional study of patients who were diagnosed with symptomatic FAIS underwent preoperative MRI/MRA with axial oblique and/or radial plane imaging and had preoperative radiographs with anterior‐posterior (AP), 45° Dunn and 90° Dunn views. Alpha angle measurements were performed independently by two musculoskeletal radiologists. Inter‐rater reproducibility and inter‐method comparability between MRI/MRA images and radiographic views were assessed using the intraclass correlation coefficient (ICC) with 95% confidence interval (CI).Ninety‐seven patients were included of whom 93 (95.8%) received axial oblique plane images and 54 (55.6%) had radial plane MRI/MRA images. Inter‐rater reproducibility was excellent (ICC > 0.9) for all planes on MRI/MRA and radiographs. MRI/MRA axial oblique images had poor (ICC 0.39, 95% CI [0.09, 0.59]), moderate (ICC 0.57, 95% CI [0.18, 0.75]) and moderate (ICC 0.64, 95% CI [0.20, 0.81]) comparability with AP, 45° Dunn and 90° Dunn, respectively. MRI/MRA radial plane images had equivocal (0 included in all CIs) comparability with AP (ICC 0.66), 45° Dunn (ICC 0.35) and 90° Dunn (ICC 0.14) radiographs. On average, alpha angle measurements were significantly higher with radial images and lower with axial oblique images, when compared to all radiographic views (p < 0.05), except axial oblique versus 45° Dunn views, where angles measured on axial oblique were significantly larger.Alpha angle measurements taken on axial oblique MRI/MRA images show moderate comparability to radiographic 45° Dunn and 90° Dunn views despite negative bias to measurements taken on radiographic AP and 45° Dunn view. Larger alpha angles were appreciated on MRI/MRA radial and axial oblique views compared to radiographic views supporting the inclusion of MRI/MRA alpha angle measurements to properly identify deformity.Level II.

Background: The use of telerehabilitation after sports medicine procedures such as an arthroscopic rotator cuff repair (ARCR) and anterior cruciate ligament reconstruction (ACLR) has rapidly increased in recent years; however, the functional outcomes and patient satisfaction with telerehabilitation compared to in-person rehabilitation remain unclear. The purpose of this study was to compare the functional outcomes and patient satisfaction with telerehabilitation to in-person rehabilitation in a randomized controlled trial after two common sports procedures, ARCR and ACLR. Methods: Two randomized controlled trials were conducted involving patients scheduled to undergo ARCR or ACLR by one of six fellowship-trained sports medicine surgeons between October 2020 and November 2021. Each trial had an enrollment goal of 60 patients. Subjects were randomized 1:1 to receive telerehabilitation or in-person rehabilitation postoperatively. Functional outcome and satisfaction metrics were collected at baseline and at post-operative visits and compared between groups. Results: In total, 16 ACLR patients were enrolled, of whom 10 (62.5%) were assigned to in-person rehabilitation and 6 (37.5%) to telerehabilitation. Additionally, 32 ARCR patients were enrolled, of whom 20 (62.5%) were assigned in-person rehabilitation and 12 (37.5%) were assigned telerehabilitation. In total, of the 30 patients assigned to in-person rehabilitation, none reported a crossover to telerehabilitation. Of the 18 patients initially assigned to telerehabilitation, 12 (67%) completed the final follow-up survey, of which 11 (92%) reported a crossover; 9 patients completed in-person rehabilitation and 2 patients completed hybrid in-person and telerehabilitation. Conclusions: Patients preferred in-person rehabilitation compared to telerehabilitation after ACLR and ARCR, as evidenced by the nearly ubiquitous crossover from telerehabilitation to in-person rehabilitation in both studies. Our findings suggest that telerehabilitation protocols still need to be perfected, and that there may be a role for a hybrid in-person and tele-rehab model. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to compare opioid analgesic use and patient-reported outcomes (PROs) after anterior cruciate ligament reconstruction (ACLR) between patients with and without cannabis use disorder (CUD). Hypothesis: We hypothesized that patients with CUD would have greater postoperative opioid usage with comparable improvement in PROs. Study Design: Retrospective matched-cohort study. Level of Evidence: Level 3. Methods: We identified patients with CUD who underwent primary ACLR at a single center and had minimum 3-month follow-up. Patients with CUD were propensity score matched 1:1 to non-CUD controls with respect to age, sex, and follow-up time. Total refills, days supply, and morphine milligram equivalents (MMEs) of opioid analgesics prescribed were calculated for up to 1 year postoperatively. Patient-Reported Outcome Information System (PROMIS) instruments were used to assess PROs. Opioid use and outcomes were compared between CUD and control groups using Mann-Whitney U test and Fisher's exact test. P values <0.05 were considered significant. Results: A total of 104 patients with CUD were matched to 104 controls. Both groups were majority male (65.4% male, 34.6% female). The CUD group had a mean age of 29.9 years and mean follow-up time of 16.1 months. There was no significant intergroup difference in opioid prescription rates (CUD 82.7% vs control 83.7%, P ≥ 0.99). Among patients prescribed opioids, there were no significant intergroup differences in total days supply (P = 0.67), total MMEs (P = 0.71), or MMEs per day (P = 0.65). There were no significant differences in pre- to postoperative improvement in PROMIS Pain Intensity (P = 0.51), Pain Interference (P = 0.81), Mobility (P = 0.90), Mental Health (P = 0.74), or Physical Health (P = 0.94). Conclusion: There were no significant differences detected in opioid usage or PRO improvement after ACLR between patients with CUD and those without. However, because a sample size was not determined a priori, a larger sample may show a difference. Clinical Relevance: CUD does not appear to correlate with inferior outcomes after ACLR.

Background: Sacral stress fractures are a rare cause of low back pain in athletes. Given the low incidence of these fractures, there is a scarcity of data on symptomatology, risk factors, and clinical outcomes. Hypothesis: Patients diagnosed with sacral stress fractures would be athletes presenting with low back pain. Study Design: Case series of 13 patients with sacral stress fractures. Level of Evidence: Level 4. Methods: We conducted a retrospective review of medical records to identify patients diagnosed with sacral stress fractures at a single academic institution. Fractures were diagnosed on noncontrast T2-weighted magnetic resonance imaging scans and categorized using the Bakker classification system. Subjects were administered an electronic survey that asked about (1) the onset, time course, and location of pain and other symptoms; (2) time to treatment and treatment modalities pursued; (3) sports performance and time to return to sport; and (4) risk factors for stress fractures. Results: Of 18 eligible patients, 13 (72.2%) completed the survey with mean follow-up of 49.6 months (range, 1-144 months). Mean age was 28.0 years (range, 18-52 years); 9 patients (69.2%) were female, of whom 7 (77.8%) were premenopausal. The most common fracture type was Bakker type B (8 patients; 61.5%). Most patients presented with acute lumbosacral back pain in the setting of running/jogging activities. All patients underwent nonoperative treatment for an average of 3.8 months (range, 0-8 months) and three-quarters reported pain resolution at last follow-up. Rate of return to sport was 83.3%, but most patients reported ongoing deficits in running performance. Conclusion: Sacral stress fractures commonly present as acute lumbosacral back pain provoked by running sports. While the pain associated with these fractures prevents most athletes from participating in sports, nonoperative management appears to be an effective treatment modality with a high rate of return to sport.

Background: Spinopelvic parameters, including pelvic tilt (PT), sacral slope (SS), and pelvic incidence, have been developed to characterize the relationship between lumbar spine and hip motion, but a paucity of literature is available characterizing differences in spinopelvic parameters among patients with femoroacetabular impingement syndrome (FAIS) versus patients without FAIS, as well as the effect of these parameters on outcomes of arthroscopic treatment of FAIS. Purpose: To (1) identify differences in spinopelvic parameters between patients with FAIS versus controls without FAIS; (2) identify associations between spinopelvic parameters and preoperative patient-reported outcomes (PROs); and (3) identify differences in PROs between patients with stiff spines (standing-sitting ΔSS ≤10°) versus those without. Study Design: Cohort study; Level of evidence, 2. Methods: The study enrolled patients ≥18 years of age who underwent primary hip arthroscopy for treatment of FAIS with cam, pincer, or mixed (cam and pincer) morphology. Participants underwent preoperative standing-sitting imaging with a low-dose 3-dimensional radiography system and were matched on age and body mass index (BMI) to controls without FAIS who also underwent EOS imaging. Spinopelvic parameters measured on EOS films were compared between the FAIS and control groups. Patients with FAIS completed the modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS) before surgery and at 1-year follow-up. Outcome scores were compared between patients with stiff spines versus those without. Associations between spinopelvic parameters and baseline outcome scores were assessed with Pearson correlations. Continuous variables were compared with Student t test and/or Mann-Whitney U test, and categorical variables were compared with Fisher exact test. Results: A total of 50 patients with FAIS (26 men; 24 women; mean age, 36.1 ± 10.7 years; mean BMI, 25.6 ± 4.2) were matched to 30 controls without FAIS (13 men; 17 women; mean age, 36.6 ± 9.5 years; mean BMI, 26.7 ± 3.6). Age, sex, and BMI were not significantly different between the FAIS and control groups (P >.05). Standing PT was not significantly different between stiff and non-stiff cohorts (P =.73), but sitting PT in the FAIS group was more than double that of the control group (36.5° vs 15.0°; P <.001). Incidence of stiff spine was significantly higher in the FAIS group (62.0% vs 3.3%; P <.001). Among FAIS patients, those with stiff spines had a significantly higher prevalence of cam impingement, whereas those with non–stiff spines had a higher prevalence of mixed impingement (P =.04). No significant differences were seen in preoperative mHHS or NAHS scores or pre- to postoperative improvement in scores between FAIS patients with stiff spines versus those without (P >.05), but a greater sitting SS was found to be positively correlated with a higher baseline mHHS (r = 0.36; P =.02). Conclusion: Patients with FAIS were more likely to have a stiff spine (standing-sitting ΔSS ≤10°) compared with control participants without FAIS. FAIS patients with stiff spines were more likely to have isolated cam morphology than patient without stiff spines. Although sitting SS was positively correlated with baseline mHHS, no significant differences were seen in 1-year postoperative outcomes between FAIS patients with versus without stiff spine.

Females of reproductive age constitute one of the largest demographics of the hip arthroscopy population, but it is unclear as to how pregnancy planning affects decision-making regarding surgery or vice versa. The purpose of this study was to assess perceived risks to pregnancy from hip pain and/or hip arthroscopy among reproductive-age females who underwent arthroscopic treatment of femoroacetabular impingement syndrome (FAIS). A cross-sectional study was conducted involving females aged 18–44 years who underwent hip arthroscopy for the treatment of FAIS, with a single surgeon included in the study. Subjects completed a survey that assessed obstetric and gynecologic history, decision-making regarding the planning and timing of hip surgery and pregnancy, and perceived risks to pregnancy from hip pain and/or hip surgery. Subjects were classified as nulligravid (Group 1), pregnant at least once before hip surgery but never again following hip surgery (Group 2), or pregnant at least once following hip surgery (Group 3). A total of 85 patients were enrolled with a mean age of 32.3 ± 6.5 years at the time of surgery. The mean follow-up time was 51.9 ± 34.5 months. There were 39 subjects in Group 1 (45.9%), 20 in Group 2 (23.5%), and 26 in Group 3 (30.6%). About half of all subjects expressed "some" to "a lot of" concern that their hip pain could get worse during pregnancy (49.4%), and about half had "no concern" that hip arthroscopy would affect the health of their fetus/baby (54.1%). Reproductive-age females undergoing hip arthroscopy for FAIS generally consider the procedure to be safe with respect to future pregnancy outcomes. [ABSTRACT FROM AUTHOR]

Background: Exertional compartment syndrome (ECS) is an underdiagnosed cause of lower extremity pain among athletes. The condition can be managed operatively by fasciotomy to relieve excess compartment pressure. However, symptom recurrence rates after fasciotomy are considerable, ranging from 3% to 17%. Hypothesis: Leg paresthesia and its distribution during ECS episodes would be a significant predictor of outcomes after fasciotomy. Study Design: Retrospective cohort study. Level of Evidence: Level 4. Methods: We conducted a retrospective chart review of patients who underwent fasciotomy for ECS at our center from 2010 to 2020 (institutional review board no. 21-00107). We measured postoperative outcomes including pain frequency and severity, Tegner activity level, and return to sport. Significant predictors of outcomes were identified using multivariable linear and logistic regression. P values <0.05 were considered significant. Results: A total of 78 legs (from 42 male and 36 female participants) were included in the study with average follow-up of 52 months (range, 3-126 months); 33 participants (42.3%) presented with paresthesia. Paresthesia was an independent predictor of worse outcomes, including more severe pain at rest (P = 0.05) and with daily activity (P = 0.04), reduced postoperative improvement in Tegner scores (P = 0.04), and lower odds of return to sport (P = 0.05). Those with paresthesia symptoms in the tibial nerve distribution had worse outcomes than those without paresthesia in terms of preoperative-to-present improvement in pain frequency (P < 0.01), pain severity at rest (P < 0.01) and with daily activity (P = 0.04), and return to sport (P = 0.04). Conclusion: ECS patients who present with paresthesia have worse pain and activity outcomes after first-time fasciotomy, but prognosis is worst among those with tibial nerve paresthesia. Clinical Relevance: Paresthesia among ECS patients is broadly predictive of more severe recurrent leg pain, reduced activity level, and decreased odds of return to sport after fasciotomy.

Study Design: Retrospective cohort study. Objective: To compare patterns in opioid usage and prescriptions between patients who undergo cervical laminectomy with instrumented fusion (LF) vs cervical laminoplasty with reconstruction (LP) within single surgeon and national database cohorts. Methods: We identified patients with cervical myelopathy undergoing primary LF or LP in both a single-surgeon series cohort (2004-2018) and a nationally representative cohort drawn from the IBM® Marketscan® database (2014-2016). We recorded opioid usage within 6 months of surgery and identified differences in unadjusted opioid use rates between LF and LP patients. Multivariable logistic regression was used to evaluate the association between procedure type and postoperative opioid use. Results: Without adjusting for covariates, LF patients had a higher rate of 6-month opioid use in the single-surgeon cohort (15.7% vs 5.1%, P =.02). After adjusting for covariates, LF patients had higher odds of 6-month postoperative opioid use (OR 2.8 [95% CI 1.0-7.7], P =.04). In the national cohort, without adjusting for covariates, there was no significant difference in 6-month opioid use between LF and LP patients. Even after adjusting for covariates, we found no significant difference in odds. Conclusions: Findings from a single-surgeon cohort reveal that LF is associated with a higher rate of 6-month opioid use than LP. This is at odds with findings from a national database cohort, which suggested that LP and LF patients have similar rates of opioid usage at 6-months postoperatively. To prevent overuse of narcotics, surgeons must consider the distinct pain requirements associated with different procedures even in treatment of the same condition. [ABSTRACT FROM AUTHOR]
