This study evaluates two anaesthetic techniques namely interscalene brachial plexus block and intra-articular local anaesthetic injection. Both techniques are currently used for providing postoperative pain relief following arthroscopic shoulder stabilisation operation. It will be a randomised controlled trial involving 30 patients in two groups.
