OE Journal. 2013;1(11):135 Acta Orthop. 2011 Dec;82(6):692-8. Epub 2011 Oct 2536 patients with rheumatoid arthritis undergoing total knee arthroplasty were randomized to receive either intra-articular or extra-articular continuous infusion of local anaesthetics. Patients were assessed in terms of patient-controlled analgesia consumption and pain intensity during mobilization. The results demonstrate that patients receiving intra-articular infusion had decreased pain intensity during first exercises compared to the extra-articular infusion group. These findings indicate the potential for improving post-operative mobilization. However, there were no differences in pain relief at rest between the two treatment groups.

مؤشر الهشاشة هو أداة تساعد في تفسير النتائج المهمة، وتوفر مقياسًا لقوة النتيجة. ويمثل مؤشر الهشاشة عدد الأحداث المتتالية التي يجب إضافتها إلى نتيجة ثنائية التفرع لجعل النتيجة غير مهمة. يمثل الرقم الصغير نتيجة أضعف ويمثل الرقم الكبير نتيجة أقوى.
لماذا كانت هناك حاجة لهذه الدراسة الآن؟
Approximately 66% of patients experience severe pain following total knee arthroplasty. Optimal pain relief must encompass an intervention that is delivered pre-operatively, peri-operatively, as well as post-operatively. Local infiltration and a single-shot injection or the continuous infusion of local anaesthetics is considered an effective alternative method to epidural analgesia and femoral block. Catheter insertion to facilitate continuous infusion of local anaesthetics, performed post-operatively, is an effective substitute for local infiltration. However, the optimal site of local anaesthetic administration is unknown, therefore, indicating the need for this study.
ما هو سؤال البحث الرئيسي؟
What are the effects of either intra-articular or extra-articular continuous local anaesthetic infusion, on post-operative pain, in patients that have undergone total knee arthoplasty, measured at 48 hours?
- At 48 hours post-operatively, the overall patient-controlled analgesia consumption of morphine was similar between both treatment groups.
- There was no difference in the VAS score between groups during rest or with movement.
- There was greater physiotherapist satisfaction regarding the first mobilization in the patients receiving intra-articular infusion (p<0.05). At 48 hours post-operatively, patients receiving continuous intra-articular infusion with Ropivacaine had lower mean scores during exercise (p<0.07). Severe pain upon mobilization (VAS score greater than 7) occurred in 11 patients in the extra-articular group compared to 3 patients in the intra-articular group (p=0.03).
- No toxic side effects or post-operative complications, resulting from wound healing, were observed.
ما الذي يجب أن أتذكره أكثر؟
Continuous intra-articular infusion with ropivacaine was effective in reducing pain intensity during first exercises. Therefore, early post-operative mobilization (within 24 hours post-op) could be improved following TKA. However, intra-articular infusion was not superior to extra-articular infusion with respect to pain relief at rest.
كيف سيؤثر ذلك على رعاية مرضاي؟
Future studies with larger sample sizes are required to provide a more accurate comparison of outcomes between groups and to additionally compare complications rates.
