Overview of postoperative rehabilitation protocol – exercises [20, 21, 25–28]

Exercise	Aim	Description	Timeframe	Dosage
Self-mobilizations of the hip, pelvis and lumbar spine	To help improve mobility and pain-free movement of the hip, pelvis and lumbar spine and prevent adhesions of the hip capsule	See Additional file 3A; row 1 exercises 1–5 See Additional file 3A; row 1 exercise 6	Weeks 0–2 Weeks 2–8	1 minute per exercise, 3 times per day 1 minute per exercise
Anterior and posterior hip stretch	To help improve hip flexion and extension mobility	See Additional file 3A; row 2 exercises 1–2	Weeks 28	3–5 sets 30 seconds
Hip muscle retraining	To optimize neuromuscular control and stability of the hip	See Additional file 3A; row 3 exercises 1–5	Weeks 0–4	3 sets 12–20 repetitions
Hip muscle strengthening (focus on extensor/rotator strengthening)	To optimize neuromuscular control, stability and strength of the hip	See Additional file 3A; row 4–5 exercises 1–9	Weeks 4–14	3 sets 8–12 repetitions with increasing load based on experienced fatigue
Functional hip muscle strengthening	To optimize neuromuscular control, stability and strength of the hip in patient specific (sport) activities	Exercises based on patient-specific goals or (sport) demands such as kicking in soccer or throwing/smashing in volleyball/tennis	Weeks 10–14	3 sets 8–12 repetitions with increasing load based on experienced fatigue

The physical therapy protocol is performed by one physical therapist (MT) and is semi-structured. Loads will be adjusted based on the participants functional performance and rehabilitation goals
