Clinical Outcomes of Single-Stage Revision Anterior Cruciate Ligament Reconstruction Using a Fast-Setting Bone Graft Substitute.

Revision anterior cruciate ligament reconstruction (ACLR) can be achieved in a single-stage or two-stage approach. Single-stage revisions have several advantages, including one less operation, decreased cost, and a quicker recovery for patients. Revision ACLR can be complicated by malpositioned or dilated bone tunnels, which makes a single-stage revision more challenging or sometimes necessitates a two-stage approach. The use of fast-setting bone graft substitutes (BGS) has been described in recent literature as a strategy to potentially help address this problem in the setting of single-stage revision ACLR. The aim of this study was to evaluate patient-reported clinical outcomes of patients who have undergone single-stage revision ACLR using fast-setting BGS to address prior malpositioned or dilated tunnels. A retrospective review was conducted of the first nine consecutive patients who had undergone single-stage revision ACLR using a fast-setting BGS by a single surgeon between May 2017 and February 2020 with a minimum of 2-year follow-up. Patient-reported clinical outcomes, including the International Knee Documentation Committee (IKDC) questionnaire, the Tegner Lysholm Knee Scoring Scale, patient satisfaction questions, and the need for additional surgery were evaluated for this group between 26 and 49 months postoperative. Of the nine patients eligible for inclusion, eight patients (88.9%) were evaluated, and one was lost to follow-up. At an average follow-up of 37.9 months (range: 27.8-55.7), the mean postoperative IKDC score was 75.0 ± 11.3, and the mean postoperative Tegner Lysholm Knee Score was 83.0 ± 17.6. None of the patients required additional revision surgery or experienced construct failure at the time of follow-up. Seven of eight respondents (87.5%) had their preoperative expectations met with the surgery, and 100% of patients stated they would have the surgery again. Single-stage revision ACLR using fast-setting BGS showed overall positive clinical outcomes for this pilot group of patients at a minimum 2-year follow-up. In select revision scenarios, these materials may be a valuable option to allow the filling of defects without compromising fixation or clinical outcomes.

Mild Biceps Tendonitis May Be Managed Nonoperatively During Shoulder Arthroscopy.

Purpose: The purposes of this study were to determine whether patients with mild biceps tendonitis required revision surgery after the biceps tendon was not surgically treated, while addressing concomitant pathology, and to evaluate whether preoperative groove pain affected patient-reported outcomes. Methods: Patients who underwent shoulder arthroscopy between 2015 and 2018 by a single surgeon for rotator cuff pathology, debridement, and distal clavicular excision (DCE), with or without subacromial decompression (SAD), and where the biceps tendon was not surgically addressed were retrospectively identified. Inclusion criteria were mild LS (<50% hyperemic appearing biceps tendon arthroscopically), and a minimum 2-year follow-up. The primary outcome measure was the incidence of revision surgery. Secondary outcomes included American Shoulder and Elbow Surgeons (ASES) score, simple shoulder test (SST), pain level, and satisfaction scores. Two sample t-tests compared postoperative patient-reported outcomes based on the presence or absence of preoperative bicipital groove tenderness. Results: Sixty-four of 69 eligible subjects (93%) were evaluated at a minimum of 2 years postoperatively. One out of 64 subjects underwent revision to perform a biceps tenodesis. Overall, patients had high patient-reported outcome measures (PROMs) postoperatively. Ninety-seven percent of patients reported they would have the surgery again. The presence of preoperative bicipital groove tenderness had no effect on ASES (P = .62), SST (P = .83) scores, and postoperative pain (P = .65). Patients without bicipital groove pain had average respective ASES and SST scores of 93.70 ± 11.84 and 10.66 ± 2.47; those with bicipital groove pain averaged 92.00 ± 15.31 and 10.78 ± 1.87. There was no significant difference in overall satisfaction scores between patients with groove pain (9.42 ± 1.40) and those without (9.46 ± 1.38; P = .92). Conclusions: Patients with mild biceps tendonitis showed favorable outcomes with low revision rates and high patient satisfaction when the biceps tendon was not surgically addressed when the primary shoulder pathology was treated during arthroscopy, independent of preoperative groove pain. Level of Evidence: Level III, retrospective cohort study.

Bony Edema and Clinical Examination Findings Predict the Need for Distal Clavicle Excision at the Time of Shoulder Arthroscopy.

Background: Deciding to perform a distal clavicle excision for acromioclavicular joint arthritis, especially in conjunction with other arthroscopic shoulder procedures, is challenging for surgeons. Studies have reported mixed results on the value of magnetic resonance imaging (MRI) in decision making. Purpose: We sought to correlate MRI findings with clinical symptoms and the surgeon's decision to perform a distal clavicle excision. Methods: We compared MRI, clinical examination, and MRI findings of 200 patients who underwent distal clavicle excision for symptomatic acromioclavicular joint arthritis with 200 patients who underwent arthroscopic shoulder procedures for other reasons. Univariate statistics were used to determine correlations between physical examination findings, MRI findings, and the decision to perform distal clavicle excision. A binary logistic regression model was used to determine independent predictors of need for distal clavicle excision. Results: There was no difference in mean age, sex, and race between groups. Advanced acromioclavicular joint osteoarthritis was strongly correlated with positive physical examination findings. Bony edema correlated strongly with tenderness at the acromioclavicular joint but not pain with cross-body adduction testing. There was no association between higher MRI grade of osteoarthritis and the need for distal clavicle excision. Regression analysis identified both physical examination findings and bony edema on MRI as independent predictors of the need for distal clavicle excision. Conclusion: In the setting of positive clinical examination findings and bony edema of the distal clavicle, surgeons should feel reassured that distal clavicle excision is likely indicated.

Hip Stability May Influence the Development of Greater Trochanteric Pain Syndrome: A Case-Control Study of Consecutive Patients.

BACKGROUND: Greater trochanteric pain syndrome (GTPS) is thought to relate primarily to tendinosis/tendinopathy of the hip abductors. Previous studies have suggested that certain anatomic factors may predispose one to development of the condition. HYPOTHESIS: It was hypothesized that intrinsic acetabular bony stability of the hip is related to the development of GTPS. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A total of 198 consecutive patients diagnosed with GTPS were compared with 198 consecutive patients without clinical evidence of GTPS. Electronic health records of the included patients were examined; data recorded included patient age, sex, race, and body mass index (BMI). Standing anteroposterior radiographs were evaluated by 2 blinded examiners who measured the Tönnis angle, lateral center-edge angle (LCEA), and acetabular depth/width ratio (ADW) and assessed for the presence of a posterior wall sign. The number of dysplastic measures was recorded for each patient based on published norms. Associations between radiographic and patient variables versus the presence or absence of GTPS were determined. Factors with univariate associations where P < .20 were included in a binary logistic regression model to identify independent predictors of the presence of GTPS. RESULTS: There was no difference between groups in terms of age, BMI, or race. There were significantly more women than men in the GTPS group (71% vs 30%; P < .001). Intraclass correlation coefficients were good for the LCEA (0.82) and Tönnis angle (0.82) and poor (0.08) for the ADW. Kappa was moderate for the presence of a posterior wall sign (0.51). An increased Tönnis angle, decreased ADW, and ADW <0.25 were significantly associated with the presence of GTPS. The binary logistic regression model identified an increased Tönnis angle (P < .010) and female sex (P < .001) as independent risk factors for GTPS. CONCLUSION: Based on this preliminary retrospective study, decreased intrinsic acetabular bony stability of the hip may be associated with an increased risk of GTPS.
