Table 1 Modified Coleman Methodology Score[6]

Section	No. or factor	Score
Part A: Only one score to be given for each section
1 Study size - number of patients
	> 60	10
	41-60	7
	20-40	4
	< 20, not stated	0
2 Mean follow up (mo)
	> 24	5
	12-24	2
	< 12, not stated or unclear	0
3 Number of different surgical procedures included in each reported outcome. More than one surgical technique may beassessed but separate outcomes should be reported
	One surgical procedure	10
	More than one surgical procedure, but > 90% of subjects undergoing the one procedure	7
	Not stated, unclear, or < 90% of subjects undergoing the one procedure	0
4 Type of study
	Randomized controlled trial	15
	Prospective cohort study	10

	In > 80%	3
	In < 80%	0
6 Description of surgical procedure given
	Adequate (technique stated and necessary details of that type of procedure given)	5

	Not adequately described (2 items between ROM and WB and sport)	5
	Protocol not reported	0
Part B: Scores may be given for each option in each of the three sections if applicable
1 Outcome criteria
	Outcome measures clearly defined	2
	Timing of outcome assessment clearly stated (e.g., at best outcome after surgery or follow-up)	2
	Objective, subjective and imaging criteria	6
	2 items between objective, subjective and imaging criteria	4

2 Procedure for assessing outcomes
	Subjects recruited (results not taken from surgeons files)	5

	Completion of assessment by subjects themselves with minimal investigator assistance	3
3 Description of subject selection process
	Selection criteria reported and unbiased	5
	Recruitment rate reported
	> 80% or	5
	< 80%	3
	Eligible subjects not included in the study satisfactorily accounted for, or 100% recruitment	5

MRI: Magnetic resonance imaging; ROM: Range of motion; WB: Weight bearing.
