Background: Little data exist in the literature regarding second-look arthroscopic outcomes after pullout repair for avulsion tears of the posterior lateral meniscus root. Purpose: To (1) assess the functional, magnetic resonance imaging (MRI), and second-look arthroscopic outcomes after pullout repair for avulsion tears of the posterior lateral meniscus root; (2) determine which demographic and clinical factors influenced healing of the repaired posterior lateral meniscus root; and (3) compare outcomes between different meniscal healing status groups. Study Design: Case series; Level of evidence, 4. Methods: A total of 31 patients underwent pullout repair for avulsion tears of the posterior lateral meniscus root and had a minimum 2-year follow-up. Functional outcomes were assessed using patient-reported scores (Lysholm, Tegner, and International Knee Documentation Committee [IKDC] scores). Lateral meniscal extrusion, cartilage degeneration of the lateral compartment, and healing of the repaired posterior lateral meniscus root were assessed via MRI. The healing status was also assessed using second-look arthroscopic surgery, and the patients were divided into different healing status groups. Results: The postoperative patient-reported scores improved significantly compared with the preoperative values ( P = .001). Lateral meniscal extrusion was reduced significantly from 3.37 ± 0.82 mm preoperatively to 0.63 ± 0.80 mm at final follow-up ( P = .001). The grade of cartilage degeneration of the lateral compartment progressed from 0.69 ± 0.67 preoperatively to 0.95 ± 0.83 at final follow-up ( P = .213). MRI scans showed complete healing in 28 patients (90.3%) and partial healing in 3 patients (9.7%). Second-look arthroscopic surgery showed stable healing in 18 of 23 patients (78.3%) and lax healing in 5 of 23 patients (21.7%). Patients with stable healing had significantly higher Lysholm and IKDC scores, more reduction of meniscal extrusion, and less progression of cartilage degeneration than did patients with lax healing ( P < .05). Concomitant anterior cruciate ligament reconstruction was found to significantly positively influence healing of the repaired posterior lateral meniscus root ( P = .047). Conclusion: Pullout repair for avulsion tears of the posterior lateral meniscus root yielded significantly improved patient-reported scores, reduced meniscal extrusion, and a satisfactory healing rate at final follow-up. Patients with stable healing had significantly better functional and MRI outcomes than did patients with lax healing.
PurposeTo investigate the clinical outcomes after osteochondral allograft transplantation for large Hill-Sachs lesions.MethodsPatients who underwent osteochondral allograft transplantation for large Hill-Sachs lesions were identified. Clinical assessment consisted of active range of motion (ROM), American Shoulder and Elbow Surgeons score (ASES), Constant-Murley score, Rowe score, and patient satisfaction rate. Radiographic assessment was performed with CT scan.ResultsNineteen patients met the inclusion criteria. The mean age was 21.7 years. The mean preoperative size of the Hill-Sachs lesion was 35.70 ± 3.02%. The mean follow-up was 27.8 months. All grafts achieved union at an average of 3.47 months after surgery. At the final follow-up, graft resorption was observed in 43.1% of patients. The average size of residual humeral head articular arc loss was 12.31 ± 2.79%. Significant improvements (P < .001) were observed for the active ROM, ASES score, Constant-Murley score, and Rowe score. The overall satisfaction rate was 94.7%. No significant difference was found between the resorption group and the nonresorption group in postoperative clinical outcomes.ConclusionOsteochondral allograft transplantation is a useful treatment option for patients with large Hill-Sachs lesions. Although the incidence of graft resorption may be relatively high, the clinical outcomes at a minimum 2-year follow-up are favorable.Level of evidenceLevel IV, case series
ObjectiveThe optimal repair method for bursal‐side partial‐thickness rotator cuff tears (PTRCTs) involving >50% of the thickness remains a controversial topic. The study was aimed to compare the functional and magnetic resonance imaging (MRI) outcomes after in situ repair or tear completion before repair of bursal‐side PTRCTs.MethodsA retrospective clinical study was conducted involving 58 patients who underwent in situ repair or tear completion before repair of bursal‐side PTRCTs between January 2019 and December 2020. These patients were divided into two groups: the in situ repair group and the tear completion before repair group. Functional assessment consisted of active range of motion (ROM), visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, and Constant–Murley score. The percentages of patients in each group achieving the minimal clinical important difference (MCID) of the functional scores were determined. The healing status of the rotator cuff was assessed by postoperative MRI.ResultsThere were no statistically significant differences between the two groups in terms of demographic data. The mean follow‐up period was 14.53 ± 2.64 months in the in situ repair group and 15.40 ± 2.66 months in the tear completion before repair group. At the final follow‐up, the forward elevation, external rotation, and internal rotation improved significantly in both groups. The VAS, ASES score, and Constant–Murley score improved significantly in the in situ repair group (5.17 ± 2.00 points to 0.11 ± 0.41 points, p = 0.001; 44.04 ± 17.40 points to 95.47 ± 4.32 points, p = 0.001; 49.50 ± 14.38 points to 93.50 ± 3.49 points, p = 0.001) and in the tear completion before repair group (5.43 ± 3.32 points to 0.03 ± 0.18 points, p = 0.001; 41.50 ± 19.59 points to 95.94 ± 2.68 points, p = 0.001; 47.54 ± 17.13 points to 93.97 ± 2.61 points, p = 0.001). Postoperative MRI revealed that the re‐tear rate was 7.1% (2/28) in the in situ repair group and 3.3% (1/30) in the tear completion before repair group. No significant differences were observed in terms of the functional scores, the percentages of patients achieving the MCID of the functional scores, and the re‐tear rate between the two groups (p > 0.05).ConclusionsBoth in situ repair and tear completion before repair yielded satisfactory clinical outcomes for patients with bursal‐side PTRCTs. No significant differences were observed in the functional and MRI outcomes between the two groups.
Objective: To determine the radiographic and functional outcomes after autologous iliotibial band with Gerdy's tubercle (ITB-GT) interposition in patients with irreparable rotator cuff tears (IRCTs). Methods: From December 2015 to March 2017, a total of 16 patients who underwent autologous ITB-GT interposition for IRCTs were identified, including 4 males and 12 females. The mean age was 56.1 AE 10.3 years (range, 44-67 years). Functional assessment consisted of active range of motion (ROM), Visual Analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, and patient satisfaction rate. The tendon integrity and acromiohumeral interval (AHI) were assessed by postoperative magnetic resonance imaging (MRI). Results: The mean duration of follow-up was 25.3 AE 3.5 months. At final follow-up, the patients exhibited significantly improved forward elevation, external rotation, and internal rotation (75.00
