Study on clinical characteristics and surgical methods of bucket-handle meniscal tears / 中国修复重建外科杂志

OBJECTIVE@#To summarize the clinical features, surgical methods, and prognosis of bucket-handle meniscal tears (BHMTs), and provide guidance for clinical treatment.@*METHODS@#The clinical data of 91 BHMTs patients (91 knees), who met the selection criteria and were admitted between January 2015 and January 2021, was retrospectively analyzed. There were 68 males and 23 females. Age ranged from 16 to 58 years with an average of 34.4 years. The injury was caused by sports in 68 cases, traffic accident in 15 cases, and falls or sprains in 8 cases. There were 49 cases of left knee injury and 42 cases of right knee injury. The time from the onset of symptoms to the admission ranged from 1 day to 13 months (median, 18 days), including >1 month in 35 cases and ≤1 month in 56 cases. Medial BHMTs occurred in 52 cases and lateral BHMTs in 39 cases. There were 36 cases with ACL rupture and 12 cases with discoid meniscus. The knee extension was limited more than 10° in 55 cases. According to the condition of meniscus injury, the meniscus suture with Inside-out combined with All-inside techniques (54 cases) or meniscoplasty (37 cases) under arthroscopy were selected. ACL reconstruction was performed in all patients with ACL rupture with autogenous hamstring tendon. Postoperative complications were observed. International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score were used to evaluate knee function, and clinical failure was recorded.@*RESULTS@#Two patients developed intermuscular venous thrombosis, which improved after oral anticoagulant therapy. No vascular injury, postoperative infection, joint stiffness, or other complications occurred in all patients. All patients were followed up 24-95 months, with a median of 64 months. A total of 12 cases (13.19%) failed the operation and were re-operated or given oral anti-inflammatory analgesics and rehabilitation therapy. At last follow-up, IKDC score and Lysholm score of 91 patients significantly increased when compared with those before operation ( P<0.05), while Tegner score significantly decreased ( P<0.05). The above indexes of patients treated with meniscus suture and meniscoplasty were also significantly different from those before operation ( P<0.05).@*CONCLUSION@#BHMTs occurs mostly in young men and is one of the important reasons for the limitation of knee extension after trauma. Arthroscopic meniscus suture and meniscoplasty can obtain good effectiveness according to individual conditions of patients. But the latter can better preserve the shape and function of meniscus, and theoretically can obtain better long-term outcomes, which needs to be confirmed by further research with larger sample size.

Dolor posoperatorio en pacientes sometidos a artroscopia de cadera con la técnica dentro-fuera en comparación con la técnica fuera-dentro / Douleur postopératoire chez les patients traités par la technique arthroscopique de dehors en dedans en comparaison avec la technique de dedans en dehors au niveau de la hanche / Postoperative pain in patients undergoing hip arthroscopy with inside-out technique compared with the outside-in technique

Objetivo: comparar el dolor posoperatorio en pacientes sometidos a artroscopia de cadera con la técnica dentro-fuera en comparación con la técnica fuera-dentro. Métodos: se realizó un estudio prospectivo en el que se comparó el dolor posoperatorio en un grupo de pacientes (n = 31) a los que se les realizó artroscopia de cadera mediante la técnica fuera-dentro, con los pacientes (n = 31) a los que se les realizó con la técnica dentro-fuera; ambos grupos de pacientes recibieron la misma analgesia multimodal. Los parámetros principales medidos fueron: la escala visual análoga en diferentes momentos hasta 24 horas después de la operación y la necesidad de opiáceos. Para las variables categóricas se realizó la comparación mediante Chi cuadrado, y para las variables cuantitativas mediante t Student o Mann-Whitney. Se calcularon el OR y el IC 95 por ciento. Para el análisis de los datos se utilizó el programa SPSS versión 21.0 y se consideró un error alfa de 5 por ciento. Resultados: la escala visual análoga posoperatoria fue menor en pacientes con la técnica de fuera-dentro después de 1 hora (diferencia media 1,9 IC 95 por ciento: 0,5 a 3,2, p = 0,01), después de 2 horas (diferencia media 1,29 IC 95 por ciento: 0,3 a 2,2, p = 0,01), y en el momento del alta (diferencia media 0,77 IC 95 por ciento: 0,16 a 1,18; p = 0,01). Sin embargo, 24 horas después del procedimiento, la diferencia no fue significativa (diferencia media 0,4 IC 95 por ciento: 0,02 a 0,84; p = 0,08). Las necesidades de opioides en el posoperatorio fueron significativamente menores en los pacientes con la técnica fuera-dentro ─6,5 por ciento vs. 41,9 por ciento─ (OR crudo 0,09 IC 95 porciento: 0,02 a 0,47; p = 0,004), incluso después de ajustar por edad, sexo y el IMC (OR ajustado 0,09 IC 95 por ciento: 0,016 hasta 0,51, p = 0,006). Conclusiones: los pacientes a los que se les realiza artroscopia de cadera con la técnica fuera-dentro tienen menos dolor posoperatorio y requerimientos de opioides que aquellos a los que se les realiza la técnica dentro-fuera(AU)

Objective: compare postoperative pain in patients undergoing hip arthroscopy with the inside-out technique compared to outside-in technique. Methods: a prospective study was conducted on postoperative pain in a group of patients (n = 31) who underwent hip arthroscopy by outside-in technique, which were compared with patients (n = 31) who received the inside-out technique. Both groups of patients received the same multimodal analgesia. The main parameters were measured: visual analogue scale at different times up to 24 hours after surgery and opioid need. Categorical variables were compared using Chi-square, and quantitative variables using Student t or Mann-Whitney. OR and CI 95 percent were calculated. SPSS version 21.0 was used for data analysis program and an alpha error of 5 percent was considered. Results: postoperative visual analogue scale was lower in patients with outside-in technique after 1 hour (mean difference 1.9, 95 percent CI 0.5 to 3.2, p = 0.01) after 2 hours (mean difference 1.29, 95 percent CI 0.3 to 2.2, p = 0.01) and at discharge (mean difference 0.77, 95 percent CI 0.16 to 1.18; p = 0.01). However, 24 hours after the procedure, the difference was not significant (mean difference 0.4, 95 percent CI 0.02 to 0.84; p = 0.08). Opioid requirements postoperatively were significantly lower in patients with the outside-in technique ─6,5 percent vs. 41.9 percent─ (crude OR 0.09 95 percnt CI 0.02 to 0.47; p = 0.004), even after adjusting age, sex and BMI (adjusted OR 0.09, 95 percent CI: 0.016 to 0.51, p = 0.006). Conclusions: Patients who underwent hip arthroscopy with outside-in technique have less postoperative pain and opioid requirements that those who undergo the inside-out technique(AU)

Objectif: le but de ce travail est de comparer la douleur postopératoire chez des patients opérés par la technique arthroscopique de dedans en dehors avec la technique de dehors en dedans au niveau de la hanche. Méthodes: une étude prospective a été réalisée afin de comparer la douleur postopératoire dans un groupe de patients traités par la technique arthroscopique de dehors en dedans (n = 31) et dans un groupe de patients traités par la technique arthroscopique de dedans en dehors (n = 31) au niveau de la hanche. Tous les deux groupes ont reçu une analgésie multimodale. On a fondamentalement évalué des paramètres tels que l'échelle visuelle analogique (EVA) en différents moments, même 24 heures après l'opération, et le besoin d'opiacés. Pour les variables catégoriques, on a utilisé le test de Chi carré, et pour les variables quantitatives le test du t de Student ou de Mann-Whitney. On a également calculé l'OR et l'IC 95 pourcent. Pour l'analyse des données, on a utilisé le logiciel SPSS v21.0, et une erreur alpha de 5 pourcent a été considérée. Résultats: la valeur EVA en postopératoire a été inférieure chez les patients opérés par la technique de dehors en dedans après 1 h (différence moyenne 1.9 IC 95 pourcent : 0.5 à 3.2, p = 0.01), après 2 h (différence moyenne 1.29 IC 95 pourcent : 0.3 à 2.2, p = 0.01), et à la sortie de l'hôpital (différence moyenne 0,77 IC 95 pourcent : 0.16 à 1.18 ; p = 0.01). Par contre, la différence n'a pas été significative (différence moyenne 0.4 IC 95 pourcent : 0.02 à 0.84 ; p = 0.08) 24 h après le geste opératoire. Le besoin d'opiacés en postopératoire a été significativement inférieur chez les patients traités par la technique de dehors en dedans ─6.5 pourcent vs. 41.9 pourcent─ (OR cru 0.09 IC 95 pourcent : 0.02 à 0.47 ; p = 0.004), même après l'ajustement par âge, sexe et IMC (OR ajusté 0.09 IC 95 pourcent : 0.016 jusqu'à 0.51, p = 0.006). Conclusions: on conclut que les patients traités par la technique arthroscopique de dehors en dedans souffrent moins de douleur postopératoire et n'ont pas besoin d'opiacés que ceux qui ont été traités par la technique arthroscopique de dedans en dehors.

Affecting Factors to Arthroscopic Inside-Out Repair of Isolated Meniscus Tear

PURPOSE: Clinical outcomes of arthroscopic meniscal repair for isolated meniscal tear were investigated and the factors affecting the outcome were determined MATERIALS AND METHODS: We examined 25 cases of 24 patients with isolated meniscal injury who underwent arthroscopic meniscal repair follow-up for more than 1 year. Results were evaluated by clinical healing criteria and Lysholm score in relation with age, elapsed time to surgery, location, length & patterns of tear. RESULTS: 20 cases (80%) were clinically healed. The average Lysholm scores improved from 69.3 to 86.2. Those who were under the age of 30 years old had significant relationship with rates of clinical healing. The length, patterns, location of tear, and elapsed time to surgery affected clinical results but, they did not have statistic significance. CONCLUSION: In spite of some limitations of indication, arthroscopic inside-out meniscal repair in isolated meniscal tears provide reliable method for successful outcome. Age at the time of injury has positive correlation with clinical result.

Arthroscopic Meniscal Repair Using Inside-Out Technique under Minimized Skin Incision

PURPOSE: The purpose of this study was to investigate the effect of the Inside-Out arthroscopic repair technique using minimized skin incision for the peripheral tear of the meniscus. MATERIAL AND METHOD: We treated 44 meniscal tears of 39 patients with Inside-Out arthroscopic repair technique using minimized skin incision from December 1995 to November 1997 and evaluated the result retrospectively. Follow-up period was from 23 months to 50 months(average 34.5 months) and patient age was from 4 to 55(average 26.7). Twenty cases(45%) were injured during sports and 34 cases(77%) were chronically injured case. Ninteen cases(43%) were combined with ligament injuries and among them, 18 cases had an anterior cruciate ligament injury. All cases had peripheral tear and 12 cases were bucket handle tear and 8 cases were tear of discoid meniscus and 3 cases had meniscal cyst. RESULT: During follow-up period, 41 cases(95%) were satisfied and had excellent or good results which were based on the evaluation form of Tapper & Hoover's criteria. Recurrences of meniscal tear were occurred in two cases and they were resutured arthroscopically. As complications, three cases had skin dimplings at the suture site and they were treated with subcutaneous dissection at the out patient clinic. CONCLUSIONS: Even if not many cases and short follow-up periods, we obtained good result. Therefore, we recommend the Inside-Out arthroscopic repair technique using minimized skin incision for the periph-eral tear of the meniscus in any repairable condition.
