Most patients brace for a long, painful, heavily restricted recovery. The biggest surprises after hip replacement are almost always how much easier it turns out to be. I am Dr. Cory Calendine, an orthopaedic surgeon in Franklin, Tennessee, and I perform anterior hip replacement for patients across Middle Tennessee.
At the two-week visit I hear the same surprised reactions again and again. Some are about the body, some are about how little the recovery asks of them. Here are the ones I hear most, starting with the concern almost nobody is prepared for.
The Number One Surprise After Hip Replacement: “My Leg Feels Longer”
The most common thing I hear after hip replacement is “my leg feels longer.” Most of the time it is an apparent difference, not a real one.
Why your leg feels longer at first
Arthritis wears the joint down and actually shortens the leg over time. Surgery restores your normal length, sometimes a few millimeters longer than the arthritis left you.
The reason it feels long early is muscle tightness. The muscles on the operated side pull the pelvis down toward that side, which tips the opposite foot up, so the operated leg feels longer. That tightness is normal, and it stretches out with time. The treatment is simple: walk, walk, walk.
I tell patients to give it a few weeks before judging anything about length. The brain is used to the old, worn, shortened position, and it needs time to recalibrate to a hip that now sits where it should.
How we get leg length right in surgery
Getting leg length right in the operating room is something I take seriously. I use tools like Mako® robotic planning from a preoperative CT scan, along with live X-ray guidance with OrthoGrid, which uses AI to confirm the landmarks. That kind of robotic joint replacement planning lets me measure and match your length while I am still in the operating room, not hope for it afterward.
Sometimes I lengthen a hip by a few millimeters on purpose for stability, because a stable hip that will not dislocate always wins. And remember: most people do not have perfectly equal leg lengths to begin with. We simply get used to what we have.
If leg length is something you worry about, bring it up before surgery. We can look at your X-rays together, talk through the plan, and set realistic expectations. Knowing that a long feeling early on usually settles takes a lot of the worry out of those first weeks.
There Are Almost No Restrictions After Anterior Hip Replacement
With the anterior approach, which goes between the muscles instead of cutting through them, the hip is very stable from the start. The only counsel I give is to avoid the extremes of motion, like putting your ankle behind your head.
Otherwise, you can sleep in any position with as many pillows as you want, sit in any chair, and cross your legs right away. None of the classic “do not bend past ninety degrees” rules apply.
This catches people off guard because they have usually heard horror stories from a relative who had a hip done decades ago: the wedge pillow between the legs, the raised toilet seat, the months of sleeping flat on their back. Because the muscles around your hip are spared rather than cut, the joint holds itself together from day one, and most of those old rules simply are not necessary.
You Can Bear Full Weight Right Away
There is no weight-bearing restriction. The walker is for balance, not because the hip cannot take the load.
Most patients are off the walker in days and onto a cane, then off the cane soon after. It is common for someone to arrive at the two-week visit already off the cane and off narcotic pain medicine, walking the hallway like the surgery was weeks behind them.
Stairs surprise people too. You can usually manage a few steps the day of surgery, which matters if your bedroom is upstairs. We practice this before you go home so you feel confident, not stranded on the first floor. Driving usually returns within a couple of weeks once you are off narcotic medicine and can react safely, though I confirm that timing with each patient.
Most Patients Go Home the Same Day (and the Honeymoon Trap)
Going home the same day is expected. What surprises patients is how easy the transition is.
Nerve blocks and a long-acting injection around the joint can make the first day or two feel like a honeymoon. Soreness usually arrives around days three to five as the blocks wear off, which is exactly why doing too much too early is the trap to avoid.
I tell patients to use those easy first days to rest and let the medicine do its job, not to test the new hip with yard work or a long shopping trip. Same-day discharge is not about rushing you out; it is a sign the operation was smooth enough that home is the better place to heal. Patients who need more support, or who have other health conditions, stay a night, and that is a perfectly good plan too.

The skin is closed with sutures underneath, glued on top, and covered with a waterproof bandage. Showering right over the bandage the next day is fine. No waiting, no sponge baths, and no plastic wrap taped around your leg.
The bandage stays on until your two-week visit in most cases, so you can wash, dry off, and get on with your day. Small comforts like a real shower make the first week feel far more normal than people expect.
A Small Incision and a Hip That Feels Normal Fast
At the two-week dressing removal, patients are surprised the incision is usually around eight centimeters. The scar is smaller than most people picture when they imagine a hip replacement, and it sits on the front of the thigh where it is easy to keep clean.
Because the hip is a simple ball-and-socket joint, far simpler mechanically than the knee, a new hip can feel like your own remarkably quickly. Many patients tell me they forget which side was operated on.
A knee has to bend, glide, and rotate in a more complicated way, so it often takes longer to feel natural; a hip just swings, and that simplicity works in your favor.
Most Patients Only Need Aspirin for Blood Clots
A generation ago, hip replacement often meant strong blood thinners with twice-weekly blood draws. Today the large majority of low-risk patients take only twice-daily aspirin for clot prevention.
Higher-risk patients may still need stronger medication, but without the constant monitoring of the past. I decide this for each person based on personal and family history, not a one-size-fits-all rule.
The bigger point is what you can do yourself. Walking, staying hydrated, and getting up regularly do more to keep blood moving than any pill, which is one more reason I push early activity so hard.
What These Surprises After Hip Replacement Mean for You
Almost everything above depends on the surgical approach and on you specifically. The posterior approach remains a good operation with excellent access to the joint, and I use it here for complex cases, but it often carries the classic precautions early on.
So do not assume the rules you read online apply to you, including these. The approach your surgeon uses matters, and the right plan is individualized. The best thing you can do is ask your own surgeon which approach they are using and what that means for your first few weeks. A short, honest conversation before surgery prevents most of the surprises that worry patients afterward.
The most common thing I hear once recovery is behind my patients is “why didn’t I do this sooner.” If you would like to talk through your own hip, you can schedule a consultation at the Bone and Joint Institute of Tennessee, 3000 Edward Curd Lane, Franklin, TN 37067, or call (615) 791-2630.
