An ankle fracture with surgical fixation is one of the most common orthopaedic surgeries in Australia. The plates and screws hold the bone in place. The next three months decide whether you walk normally for the rest of your life. We see patients who recover fully and patients who never quite get there. The difference is almost always what happens in the first twelve weeks.
What ankle ORIF actually does
ORIF stands for Open Reduction Internal Fixation. The surgeon opens the ankle, realigns the bone fragments, and holds them together with plates and screws. The hardware almost always stays in permanently. It's only removed in rare cases of irritation or infection.
There are three common fracture patterns and they don't recover the same way. Lateral malleolus fractures involve the bony bump on the outside of the ankle. Most common, usually one plate, generally the most straightforward recovery. Bimalleolar fractures involve both the fibula and the medial malleolus. More unstable, both sides usually need fixing, longer recovery. Trimalleolar fractures involve the fibula, medial malleolus and the posterior tibia. Most complex pattern, longest recovery, and the highest risk of post-traumatic arthritis. Know which one you had. It changes the next twelve weeks.
Your protocol depends on the pattern
Simple lateral malleolus ORIF is often weight-bearing in a CAM boot at two to four weeks. Bimalleolar fractures are typically non-weight-bearing for six weeks, then progressive in a boot. Trimalleolar fractures usually need six to eight weeks non-weight-bearing with slower progression after that. Yours may be different. Get the protocol in writing from your surgeon and bring it to physio.
What the timeline looks like
- Week 0 to 2: Splint or boot. Foot elevated above heart for around 80% of waking hours. Ice four to six times a day. The swelling is the enemy in this phase.
- Week 2 to 6: Wound review, sutures out, often a transition to a removable walker boot. Hip and knee strength work on both sides. Don't let the rest of the leg waste away.
- Week 6 to 10: Out of the boot for set periods. Range of motion is the priority. Dorsiflexion target by week ten is 10+ degrees, plantarflexion 30+ degrees, single-leg stance 30 seconds.
- Week 10 to 16: Strength work dominates. Calf raises, squats, lunges, step-ups. Balance progressions on stable then unstable surfaces. Target 25+ single-leg calf raises by week sixteen.
- Month 4 to 6: Return to running, hopping, sport-specific drills. Cutting sports take longer than straight-line running.
The two things you'll fight: dorsiflexion and the calf
Dorsiflexion is pulling the toes up toward you. It's the hardest direction to recover after ankle ORIF and the one that affects walking the most. The joint capsule, the calf and the Achilles all get tight while you're in the boot. Daily mobility work, including loaded dorsiflexion, calf stretches and knee-over-toe drills, is the only way to recover it. Skip a week and you set yourself back four.
The calf is the second fight. Your calf on the injured side will be visibly smaller for months. Walking won't rebuild it. You need specific, heavy, slow loaded calf raises. Three sets of eight to twelve, twice a week, progressed in load. Patients who skip this end up with a permanent strength asymmetry.
The bone is healed at six weeks. The ankle isn't ready for sport until month four to six. Don't confuse the two.
Common mistakes
Four patterns we see at the Liverpool clinic. First, underestimating how stiff the ankle gets. Dorsiflexion is brutal to recover and needs daily attention, not weekly. Second, skipping the calf rebuild. Walking doesn't get the calf back, loaded work does. Third, returning to running too early. The bone may be healed but the proprioception and soft tissue aren't. Use the return-to-run criteria, not a calendar date. Fourth, accepting persistent swelling as the new normal. Swelling at three to six months is common but it's manageable. Compression, elevation, controlled loading.
How we structure ankle ORIF rehab
We typically see ankle ORIF patients fortnightly through the boot phase, then twice a week from weeks six to twelve when the real range of motion and strength work happens, then weekly through month four, then as needed for return-to-sport progression. We work directly with your orthopaedic surgeon's rooms to confirm your weight-bearing protocol if you give us permission. Book a 30-minute initial during the boot phase if you can, and a 60-minute when you're cleared for progressive loading.
