Clinical Trial Summary

The goal of this randomised controlled trial is to compare a tuberositas transposition (TTT) surgery with a home exercise program (HEP) in patients with patellofemoral pain syndrome (PFPS). The study aims to evaluate the efficiency of TTT in conjunction with a HEP compared to a HEP alone in patients with chronic PFPS.

Participants will randomly be allocated to the surgery or HEP group. Researchers will compare the surgery and HEP groups to see if activity-related pain and patient reported outcome measures (PROMs) are different.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual analogue pain score (VAS)	10-cm (0-10) visual VAS to assess activity-related pain. Higher scores reflect higher pain.	baseline and 12 weeks after HEP or 18 weeks after TTT surgery
Secondary	Kujala pain score	The Kujala Score or Anterior Knee Pain Scale (AKPS) is a 13-item questionnaire to evaluate subjective symptoms and functional limitations in patients with PFP. The AKPS is graded on a scale of 0-100, with 100 reflecting no signs of PFP.	baseline, after 12 weeks after HEP or 18 weeks after TTT surgery, 26 weeks, and 1 year
Secondary	International Knee Documentation Committee Subjective Knee Form (IKDC)	The IKDC is a tool containing 7 items on knee symptoms, 2 on function, and 2 on sports activities, resulting in a score from 0-100, with 100 reflecting the highest level of pain and functional restrictions.	baseline, after 12 weeks after HEP or 18 weeks after TTT surgery, 26 weeks, and 1 year
Secondary	Tegner Activity Score	The Tegner Activity Score consists of 1 item, scoring the level of work- and sport activities, which is scored by a 10-point scale with 10 reflecting high level of activity.	baseline, after 12 weeks after HEP or 18 weeks after TTT surgery, 26 weeks, and 1 year
Secondary	EuroQol health-related quality of life (EQ-5D-5L) questionnaire	The health-related quality of life (EQ-5D-5L) questionnaire consists of states of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) that are scored on 5 levels (no problems, slight problems, moderate problems, severe problems, and extreme problems). An index value will be calculated to reflect health state on a scale of 0 to 1, where 1 represents maximum quality of life.	baseline, after 12 weeks after HEP or 18 weeks after TTT surgery, 26 weeks, and 1 year
Secondary	Visual analogue pain score (VAS)	10-cm (0-10) visual VAS to assess activity-related pain. Higher scores reflect higher pain.	after 6 weeks, 26 weeks, and 1 year
Secondary	Knee functionality using Decline step down test (DSDT)	The DSDT is a performance test simulating stair descent. It assesses maximum pain-free flexion angle, from 0 to 90 degrees. Larger angles reflect higher functionality of the knee.	baseline and after 26 weeks
