Construct a PICO to answer the question: Which surgical technique should be used to repair a cranial cruciate ligament (CCL) rupture in a Labrador?

	Does [surgery] provide a [good recovery] in [Labradors] with [CCL rupture]?
	In [dogs over 25kg with CCL rupture] does [tibial plateau levelling osteotomy] compared with [lateral fabellar suture] have a [greater chance of return to normal limb function]?
	In [dogs] does a [tibial plateau levelling osteotomy] work better than [lateral fabellar suture] for [CCL rupture]?
	In [large dogs] is [tibial plateau levelling osteotomy] superior for correcting [CCL rupture]?
	[Which technique] provides the [best outcome] for [CCL rupture]?

How should you approach a clinical question with multiple possible interventions or outcomes?

	Construct a series of PICOs, each containing one comparator and one outcome, until all questions are answered.
	Expand the PICO to contain all of the relevant comparators and outcomes
	Expand the PICO to contain some, but not all of the extra comparators and outcomes
	Ignore the other comparators and outcomes; one is enough to get the best evidence
	It is not possible to use the PICO format for questions with multiple comparators or outcomes.
