Methods RCT; computer‐generated block randomisation
Participants Unicompartmental knee OA: n = 117
 Male/ female: 69/48
 Mean age (years): 59
 Mean BMI (kg/m2): 28.5
 Varus: n = 95/valgus: n = 22
 Mean varus (degrees) = 188
 Mean valgus (degrees) = 173
Interventions I = Brace intended to reduce load (n = 60) vs C = standard conservative treatment (n = 57)
 Follow‐up: 12 months
Outcomes VAS, HSS knee score, walking distance, EuroQol
Notes No competing interests
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "patients were randomised according to a computer‐generated procedure in blocks of 24"
Allocation concealment (selection bias) Low risk Quote: "the allocation of treatment was concealed until after the patient was included and baseline measurements were executed; sealed envelopes contained the group assignment"
Blinding (performance bias and detection bias) 
 All outcomes Low risk Outcome assessor of the HSS knee was blinded for allocation
Blinding of participants and personnel (performance bias) 
 All outcomes High risk Participants were not blinded; outcome assessor of the HSS knee was blinded
Blinding of outcome assessment (detection bias) 
 All outcomes High risk Study used patient‐reported outcome measures; participants were not blinded. Functional outcome (HSS knee score) was measured blinded
Incomplete outcome data (attrition bias) 
 All outcomes Low risk Intention‐to‐treat
Selective reporting (reporting bias) Low risk Complete data were reported
