Postoperative pain control is important in terms of early recovery and rehabilitation in arthroscopic meniscectomy. For this purpose, we aimed to compare the effects of intraarticular tramadol, magnesium, and ketamine with combinations of pericapsular bupivacaine on postoperative pain and recovery in arthroscopic meniscectomy.


Ninety patients who underwent arthroscopic meniscectomy were enrolled in the study. Group T was given tramadol, Group K was given ketamine, and Group M was given magnesium reconstituted intraarticularly, and all groups received periarticular bupivacaine. Comparisons were made in terms of the patients’ postoperative Visual Analogue Scale scores with and without movement, need for additional analgesics, first analgesic time, mobilization times, adverse effects, and satisfaction with the analgesics.


The Visual Analogue Scale scores were lowest in Group T at 0 minutes, and were higher in the 15th and 30th minutes and 1st, 2nd, and 6th hours. Visual Analogue Scale values with movement were found to be high in Group M at 0 and 15 minutes, but they were found to be higher in group T in the 30th minute, 1st, 2nd and 6th hour. The groups were similar in terms of postoperative additional analgesic use, number of analgesic use, and satisfaction with analgesics; however, the first analgesic time was earlier in Group M, and the first mobilization time was earlier in Group K.


Intraarticular ketamine enables early mobilization and less need for additional analgesics, it also provides a better analgesic effect in comparison with intraarticular tramadol and magnesium.


O controle da dor pós-operatória é importante para recuperação e reabilitação precoces em meniscectomia artroscópica. Portanto, nosso objetivo foi comparar os efeitos de tramadol, magnésio e cetamina administrados por via intra-articular em associação com bupivacaína pericapsular sobre a dor e a recuperação após meniscectomia artroscópica.


Noventa pacientes submetidos à meniscectomia artroscópica foram incluídos no estudo. O Grupo T recebeu tramadol, o Grupo K recebeu cetamina e o Grupo M recebeu magnésio em doses reconstituídas por via intra-articular e todos os grupos receberam bupivacaína por via periarticular. As avaliações foram feitas mediante comparação dos escores em escala visual analógica no pós-operatório dos pacientes em movimento e em repouso, necessidade de analgésicos adicionais, tempo até a primeira necessidade de analgésico, tempo de mobilização, efeitos adversos e satisfação com os analgésicos.


Os escores da escala visual analógica foram menores no minuto zero e maiores nos minutos 15 e 30 e nas horas 1, 2 e 6 no Grupo T. Os escores da escala visual analógica em movimento foram maiores nos minutos zero e 15 no Grupo M e maiores no minuto 30 e nas horas 1, 2 e 6 no Grupo T. Os escores dos grupos foram semelhantes em relação à necessidade de analgésico adicional no pós-operatório, ao consumo de analgésico e à satisfação com os analgésicos, mas os tempos até a primeira necessidade de analgesia e até a primeira mobilização foram mais curtos nos grupos M e K, respectivamente.


A administração intra-articular de cetamina permite mobilização precoce e diminui a necessidade de analgésicos adicionais, além de proporcionar um melhor efeito analgésico em comparação com tramadol e magnésio por via intra-articular.
