Conditions
Interventions
Each patient will be measured with three conditions: firstly, a flexible Lycra knee brace, secondly, a single piece of medical tape applied across the knee-cap, and thirdly, nothing at all.

Inclusion criteria
Inclusion criteria: All subjects will be invited to participate who have completed the R.O.A.M. BRACE trial which involved treatment with a PF brace and repeated MRI?s. Thus, to have participated in the original study subjects needed to be eligible for MRI (see below). The criteria for the R.O.A.M. BRACE study for PFOA were: 1. Age 40 -70 (upper age limit because of the likelihood of coexistent Tibio-Femoral OA in older years). 2. Patellofemoral pain should be reproduced with stair climbing, kneeling or squatting but not with standing or walking on level ground 3. They should be on a stable medication regimen for 3 months. 4. Participants will be examined on the day on the visit and prior to the testing to assess physical findings in their knee.
Exclusion criteria
Exclusion criteria: 1. They have previously had a patellar fracture or patellar realignment surgery. 2. Predominant symptoms emanating from the tibiofemoral joint or from meniscal or ligament injury 3. Patient has rheumatoid arthritis or other forms of inflammatory arthritis 4. Intra-articular steroid injection into the painful knee in the six weeks and arthroscopy in the last 3 months. MRI scan exclusion criteria: 1. Cochlear implants 2. Any metal objects in the body including joint prostheses 3. Cardiac or neural pacemakers 4. Hydrocephalus shunts 5. Intrauterine contraceptive device or coil
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Kinetic and kinematic lower limb variables and EMG lower limb activity normalised to maximum activity during stair ascent and descent with brace, with tape or with nothing at all (control). 2. Measurements of patellar position in FWB and NWB positions using brace, tape or nothing at all on the knee. Measurements of meniscal extrusion in FWB and NWB positions. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Patellar position done clinically using a novel device and compared to the FWB MRI scans 2. Knee Pain on a 10 cm visual analogue scale (VAS) 3. Brace effectiveness on the Knee Osteoarthritis Outcome Score (KOOS) | — |
