    Time for the first necessary administration of analgesic drugs.

Secondary Outcome Measures:
  • Pain management after surgical treatment [ Time Frame: 24 hours ]

Arms Assigned Interventions
Placebo Comparator: Sham operation Procedure: Sham operation
A randomized group of patients received a placebo patch. As a supplement, each patient was given a dose of morphine, as required.
Other Name: Knee soft-tissue
Active Comparator: Knee arthroscopic surgery Procedure: Knee arthroscopic surgery
A randomized group of patients was given small patches with active 5% lidocaine.
Other Name: Knee soft-tissue

Detailed Description:

Lidocaine is well-known as analgesic treatment on skin and hypodermic veins. Since 1996 it has been documented that topical lidocaine has an analgesic effect 24 hours after surgical treatment.

The aim is to determine a possible reduction in pain after knee arthroscopy with topical lidocaine.
