Epub 2012 Oct 840 patients undergoing unicompartmental knee arthroplasty with local anaesthetic infiltration were randomized to receive a minimally invasive or conventional surgical procedure to determine if minimally invasive surgery (MIS) would result in earlier postoperative home-readiness, as well as improved pain and functional outcomes. Follow-up was conducted over 6 months postoperatively. The results indicated that there were no benefits to using MIS techniques over conventional techniques as there were no differences in the outcomes.

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؟
Many studies have investigated procedures that focused on improving postoperative pain and mobilization in patients following knee arthroplasty. Minimally invasive surgery (MIS) with local infiltration analgesia (LIA) was developed with respect to these criteria in unicompartmental knee arthroplasty on the basis that it caused less trauma to the soft tissue surrounding the knee and improved patient outcomes. However, the MIS technique is more demanding than conventional methods, and some surgeons hesitate to use it due to its longer learning curve. Moreover, there has been recent interest in the investigation of the importance of MIS with local anaesthetic infiltration, indicating the need for this study.
ما هو سؤال البحث الرئيسي؟
Did the use of minimally invasive surgery with local infiltration analgesia in unicompartmental knee arthroplasty lead to improved postoperative outcomes in pain management and mobilization when compared to conventional surgery, assessed over a 6 month period?
- Time of fulfillment for discharge criteria (home-readiness) did not statistically differ between groups (p=0.6), with the median discharge 24 (21-71) hours in the MIS group and 24 (21-46) hours in the CON group. Length of hospital stay also did not significantly differ (p=0.7).
- VAS-pain scores at rest and 60 degrees flexion did not significantly differ between groups at any time.
- There was no significant difference in analgesic consumption between groups at any time during follow up. (1 day p=0.2, 2 days p=0.6, 3 days p=0.3, 7 days p=0.2)
- Postoperative functional outcomes of patient satisfaction, Oxford Knee Score, and EQ-5D questionnaire did not significantly differ at any point during follow-up (p>0.05).
- There were numerical differences indicating better maximum knee extension and knee flexion in the MIS group, however these did not reach statistical significance (p>0.05).
- Postoperative mobilization assessed by the "time to up and go" (TUG) test showed no difference between groups at any point during follow up (p>0.05).
- Incidences of adverse events on the first postoperative were similar between groups, but nausea was significant higher in MIS patients on the second postoperative day (p=0.006). No postoperative complications were encountered in either group during the 6-month follow up period
ما الذي يجب أن أتذكره أكثر؟
MIS technique for medial unicompartmental knee arthroplasty with local anaesthetic infiltration did not provide any advantages over a conventional surgical technique with respect to postoperative home-readiness, pain, functional outcome, mobilization and adverse events.
كيف سيؤثر ذلك على رعاية مرضاي؟
The operating surgeon should decide whether to use a conventional or an MIS technique for medial unicompartmental knee arthroplasty based on preference and the individual patient characteristics, as both procedures provide similar outcomes. Further clinical assessments with extended follow-up periods may prove useful in examining any differences in long-term outcomes.
