  • Early-term effectiveness comparison of suture hook suture via double posteromedial approaches and Fast-Fix total internal suture in treatment of Ramp lesions

    ObjectiveTo compare the short-term effectiveness of suture hook suture via double posteromedial approaches and Fast-Fix total internal suture in treatment of Ramp lesions. Methods A clinical data of 56 patients with anterior cruciate ligament rupture combined with Ramp lesions, who met the selection criteria and admitted between December 2021 and February 2023, was retrospectively analyzed. The Ramp lesions were sutured using suture hook via double posteromedial approaches under arthroscopy in 28 cases (group A) and treated with Fast-Fix total internal suture under arthroscopy in 28 cases (group B). There was no significant difference in age, gender, cause of injury, type of injury, time from injury to operation, side of injury, body mass index, and preoperative Lysholm score, visual analogue scale (VAS) score, and Tegner score between the two groups (P>0.05). The patients were followed up regularly after operation, and the clinical and imaging healing of the Ramp lesion was evaluated according to the Barrett clinical healing standard and the MRI evaluation standard. Lysholm score, VAS score, and Tegner score were used to evaluate the function and pain degree of knee joint, and the results were compared with those before operation. ResultsThe incisions of the two groups healed by first intention. All patients were followed up 12-18 months (mean, 14.9 months). Postoperative McMurray tests were negative in both groups. The clinical healing rates of group A and group B were 71.4% (20/28) and 64.3% (18/28) at 6 months after operation, and 92.9% (26/28) and 82.1% (23/28) at 12 months after operation, respectively. The differences between the two groups was not significant (χ2=0.327, P=0.567; χ2=0.469, P=0.225). There was no significant difference in Lysholm score, VAS score, and Tegner score between the two groups at each time point after operation (P>0.05). The postoperative scores in the two groups significantly improved when compared with those before operation, and the scores at 12 months after operation further improved when compared with those at 6 months after operation, showing significant differences between the different time points in the two groups (P<0.05). At last follow-up, MRI examination of the knee joint showed that there were 26 (92.9%), 2 (7.1%), and 0 (0) cases of complete healing, partial healing, and nonunion in the Ramp lesion of group A, and 25 (89.3%), 1 (3.6%), and 2 (7.1%) cases in group B, respectively. There was no significant difference between the two groups (Z=−0.530, P=0.596). ConclusionSuture hook suture via double posteromedial approaches and Fast-Fix total internal suture under arthroscopy are safe and reliable in the treatment of Ramp lesion, and the knee joint function significantly improves after operation.

  • Clinical application of slope-reducing tibial osteotomy and anterior cruciate ligament revision in patients with abnormally increased posterior tibial slope

    Objective To investigate the effectiveness of slope-reducing tibial osteotomy and anterior cruciate ligament (ACL) revision in the treatment of patients with primary ACL reconstruction failure and abnormally increased posterior tibial slope (PTS). Methods The clinical data of 9 patients with primary ACL reconstruction failure and abnormally increased PTS (≥17°) who met the selection criteria between January 2018 and January 2020 were retrospectively analyzed. There were 8 males and 1 female; the age ranged from 21 to 42 years, with a median age of 30 years. Lachman test was positive in 9 patients. Pivot-shift test was negative in 6 cases, degree Ⅰ positive in 2 cases, and degree Ⅱ positive in 1 case. The PTS was (17.78±1.09)° and the anterior tibial translation (ATT) was (11.58±1.47) mm. The International Knee Documentation Committee (IKDC) score was 51.0±3.8, Lysholm score was 49.7±4.6, and Tegner score was 3.7±0.7. The time from primary reconstruction to revision was 12-33 months, with an average of 19.6 months. Slope-reducing tibial osteotomy and ACL revision were performed. The improvement of knee function was evaluated by IKDC score, Lysholm score, and Tegner score; Lachman test and Pivot-shift test were used to evaluate the stability of knee joint. PTS and ATT were measured to observe the morphological changes of knee joint. Results All the incisions healed by first intention, and there was no complication such as incision infection, fat liquefaction, necrosis, deep vein thrombosis of lower extremities, and neurovascular injury. All 9 patients were followed up 12-36 months, with an average of 25.8 months. At last follow-up, Lachman test and pivot-shift test were negative. IKDC score was 85.0±4.0, Lysholm score was 87.7±2.8, Tegner score was 6.8±0.7, PTS reduced to (9.89±0.60)°, and ATT shortened to (0.91±0.29) mm, which were significantly improved when compared with those before operation (P<0.05). ConclusionSlope-reducing tibial osteotomy and ACL revision in the treatment of patients with primary ACL reconstruction failure and abnormally increased PTS has a satisfactory short-term effectiveness. It can improve the stability of knee joint and maintain the normal shape of knee joint.
