Study information

Study design	Pilot, randomised controlled trial
Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Not specified
Study type	Treatment
Scientific title
Study acronym	KORAL
Study hypothesis	This is a pilot study, the design of which has been informed by extensive qualitative feasibility work, to assess in two UK centres (Aberdeen and North Staffordshire) the feasibility of mounting a multicentre, placebo-controlled trial to evaluate the effectiveness of arthoscopic lavage for osteoarthritis of the knee. Please note that, as of 11/05/2009, the anticipated end date has been updated from 30/06/2010 to 31/10/2008. Protocol V2 dated July 2006 is available on http://www.hta.ac.uk/protocols/200300480001.pdf
Ethics approval(s)	Application submitted to MREC, Scotland as of 09/06/06
Condition	Osteoarthritis of the knee
Intervention	1. Arthroscopic lavage (+/- debridement as deemed clinically necessary) 2. Placebo arthroscopic lavage 3. Non-operative management with specialist re-assessment
Intervention type	Other
Primary outcome measure	1. To examine whether the trial processes as currently planned are appropriate, feasible and acceptable to patients, clinicians and the trial office staff 2. To quantify the throughput of eligible patients 3. To quantify the number of patients approached and the proportion of patients who would accept randomisation to the trial 4. To examine the acceptability of the trial information material to patients
Secondary outcome measures	The secondary research outcomes of the main trial (in which we anticipate the pilot patients' data being included) are: 1. General quality of life as measured by 12-item short form questionnaire (SF-12) 2. Patient utility as measured by EQ5D 3. Non-steroidal anti-inflammatory drug (NSAID) or analgesic use 4. Use of other treatments outside the trial interventions 5. Use and cost of health services 6. Cost-effectiveness - incremental cost per quality adjusted life year gained
Overall study start date	01/07/2005
Overall study end date	31/10/2008
