Experimental: Arthroscopic Sub-acromial Decompression
Arthroscopic sub-acromial decompression surgery.
Procedure: Arthroscopic Sub-acromial Decompression Surgery
The procedure involves insertion of the arthroscope into the glenohumeral joint where the joint surface is inspected along with the intra-articular portion of the long head of biceps and the joint surface of the rotator cuff tendons. The arthroscope is then inserted into the sub-acromial bursa which lies outside the rotator cuff tendons and beneath the acromion process of the scapula. In the bursa the acromion and superior surface of the rotator cuff are assessed to ensure the coracoacromial ligament and the AC joint remains intact. The projecting under surface of the distal part of the acromion is resected.
Other Name: ASAD
Active Comparator: Shoulder Arthroscopy
Shoulder arthroscopy only.
Procedure: Shoulder Arthroscopy
This is the surgical comparison group. The procedure is performed under general anaesthetic. Patients will undergo a routine investigational arthroscopy. The operation will be performed in exactly the same manner as Group ASAD. The exception is they will not undergo the decompression (bone spur removal). Tissues will be visualised and the joint will be washed out. The time spent in theatre will be similar to that for Group ASAD. These measures provide the AO group with the characteristics necessary to provide a reasonable comparison and account for the placebo effects of surgery.
Other Name: Arthroscopy alone
Active Monitoring with Specialist Reassessment
Active monitoring with specialist reassessment - non-operative control.
Other: Active Monitoring with Specialist Reassessment
Patients will be advised that they will undergo active monitoring in the short term. They will attend a reassessment appointment 3 months after entering the study. Here, they will be asked to complete questionnaires related to their shoulder pain and undergo a clinical assessment for their shoulder. From an ethical standpoint it is emphasised that it is quite within normal practice to have a period of active monitoring.
- Oxford Shoulder Score [ Time Frame: 6 months post randomisation ]Patient reported outcome measure of shoulder pain and function.
- Oxford Shoulder Score [ Time Frame: 12 months post randomisation ]Patient reported outcome measure of shoulder pain and function
- Constant Murley Shoulder Score [ Time Frame: 6 and 12 months post randomisation ]Clinical assessment of the shoulder
- Pain DeTECT [ Time Frame: 6 and 12 months post randomisation ]Patient reported outcome related to neuropathic pain
- Quantitative Sensory Testing [ Time Frame: 6 and 12 months post randomisation ]Clinical assessment of pain and pain thresholds
- Health Economics - EQ5D [ Time Frame: 6 and 12 months post randomisation ]Patient reported expenditure and quality of life questions
- Complications [ Time Frame: 6 and 12 months post randomisation ]Patient reported complications post randomisation
- Treatment Expectations and Satisfaction [ Time Frame: 6 and 12 months post randomisation ]Patient reported questions on treatment expectations and satisfaction with treatment.
- Hospital Anxiety and Depression Scale [ Time Frame: 6 and 12 months post randomisation ]Patient reported questionnaire related to their feelings of anxiety and depression.
- Patient Response Shift [ Time Frame: 12 months post randomisation ]patient response shift on perceived disability will be assessed by comparing each patients pre-operative self-evaluation of their disability (baseline Oxford Shoulder Score) with a 12 month evaluation of their perceived pre-intervention state (the "thentest") according to the method of Razmjou et al (2010. This will give an indication of whether patients with sub-acromial pain underrate or overrate their pre-intervention disability according to their outcome.
