How Dr. Dworsky helped a retired teacher stop putting it off.

A 65-year-old retired teacher had been told she needed a hip replacement two years before she finally agreed to one. Direct anterior total hip arthroplasty got her walking unassisted on day five and back on the golf course at ten weeks. Here's the full path — including the lateral thigh numbness she wasn't expecting.

Case snapshot
  • Chief complaint — End-stage hip osteoarthritis with daily groin pain, an antalgic gait, and a steadily shrinking world. The patient had been quietly avoiding stairs, long restaurant tables, and her granddaughter's Saturday soccer games for nearly two years.
  • Treatment path — Physical therapy + activity modification + a corticosteroid injection (limited benefit), then a planned direct anterior total hip arthroplasty (THA).
  • Recovery — Walking unassisted by day 5, off cane at week 3, return to driving at week 4, return to golf and travel at week 10.
  • Outcome — Excellent pain relief and a meaningful expansion of her daily life. Two-year follow-up shows a well-positioned, well-functioning implant.
  • Honest caveat — Temporary numbness on the front and outside of the thigh from irritation of the lateral femoral cutaneous nerve lasted about 4 months before fully resolving. This is a known and typical side effect of the direct anterior approach and was discussed before surgery.
The presenting problem

Two years of putting it off.

Our patient was a recently retired elementary school teacher in her mid-sixties. She first came to LAOSS more than two years before her eventual surgery, with imaging from an outside facility that already showed end-stage right hip osteoarthritis — joint space gone, osteophytes everywhere, the femoral head no longer round. The exam matched the picture: groin pain on internal rotation, a limp she had not noticed in the mirror but her daughter had, and a steady three-out-of-ten pain at rest that climbed to seven any time she sat in a low chair.

Her first visit ended the way many do — she was not ready. She had watched a friend struggle through a complicated knee replacement and was understandably wary. We agreed on a structured non-operative plan and a standing offer to come back when she wanted to talk about surgery. She came back about twenty months later, ready, and told us what most of these patients tell us in retrospect: she wished she had not waited so long.

What conservative care looked like

Honest about what the non-surgical phase did and didn't do.

Conservative care for end-stage hip osteoarthritis is a delay strategy, not a reversal strategy. We never told her otherwise. Over the twenty months between her first visit and her surgery, she completed two full courses of physical therapy focused on hip-girdle strength and gait mechanics, modified her activities meaningfully (she gave up her morning walking group, then her short trips to the grocery store), and received two corticosteroid injections. The first injection gave her about three months of meaningful relief. The second gave her less than six weeks.

We were direct with her at each visit: the structural damage to her hip joint was not going to reverse with rehab, and viscosupplementation is not approved or supported in the hip the way it is in the knee. Conservative care was buying her time on her own terms, and that was a legitimate choice. When the time bought stopped feeling worth the cost in lost activity, she made the call.

Why we chose this approach

Why direct anterior total hip arthroplasty was the right call.

The direct anterior approach to total hip replacement enters the joint between two muscle groups instead of cutting through any muscle, which tends to translate into earlier weight-bearing and a shorter overall recovery curve. It is not a magic bullet — long-term outcomes for posterior, lateral, and anterior approaches are broadly similar in the published data when performed by an experienced surgeon — but for the right patient, the early recovery can be visibly different.

She was a good anatomic candidate (slim build, no prior open hip surgery, no extreme bony abnormalities) and her goals were specific: walk normally, get back to golf, fly to see her granddaughter without dreading the airport. The direct anterior approach offered her the fastest realistic path to all three. We chose a cementless implant with a highly cross-linked polyethylene liner, which has the longest survivorship data in the literature for her age band.

Recovery milestones

Her recovery roadmap.

Direct anterior recoveries are among the faster ones in joint replacement. These were her milestones.

01Week 1

Up and moving

Home from the surgery center the same day. Walker on day 1, off the walker by the end of the first week.

  • Full weight-bearing from the OR
  • Walked to the bathroom on day 1
  • Off walker by day 5
  • Off opioid medication by day 6
02Month 1

Reclaim daily life

Outpatient PT 2 times a week. No hip precautions with the anterior approach — she could sit, bend, and reach freely from day one.

  • Off cane at week 3
  • Driving cleared at week 4
  • Walking 1 mile continuously by week 4
  • Back to grocery shopping and cooking independently
03Month 6

Reclaim activity

By the three-month mark she was back to the activities she had given up — and by six months, the hip felt like her hip again.

  • Back to golf (full 18 holes with cart) at week 10
  • First post-op flight at week 8 with no issue
  • Yoga and Pilates at month 4
  • Pain-free at one- and two-year follow-up
Honest caveats

The numbness on the front of her thigh.

We told her before surgery that the most common side effect of the direct anterior approach is temporary numbness on the front and outside of the thigh, from stretch or irritation of a small sensory nerve called the lateral femoral cutaneous nerve. We told her it happens in some fraction of anterior hips, that it almost always resolves, and that it does not affect movement or strength — only sensation in a patch of skin. She had it. It bothered her more than she expected for the first month — she described the patch as feeling 'wrong' against her clothes — and it slowly faded over about four months until she stopped noticing it. At one-year follow-up she said she would absolutely make the same choice again. We pass that on to every anterior patient we consent.

FAQ

Honest questions other hip patients ask.

  • Better is the wrong word. In experienced hands, all three modern approaches (anterior, lateral, posterior) reach the same long-term outcome. The direct anterior approach offers a recovery curve that is, on average, faster in the first 6 weeks because no muscle is cut. Patients with significant bone deformity, prior open hip surgery, or certain body types do better with another approach. We pick the approach for the patient, not the other way around.
  • Current implant registries show roughly 90 to 95 percent of total hip replacements still in place at 15 to 20 years. The biggest variables in implant longevity are component positioning, bearing surface, patient activity, and weight. The patient in this case has a well-positioned cementless implant with a highly cross-linked polyethylene liner and is being followed at 1-, 2-, and 5-year marks.
  • No. Hip replacement is an elective procedure on the patient's timeline, not ours. Conservative care does not reverse end-stage arthritis but it can keep a patient comfortable enough to delay surgery on their own terms. As long as the patient is informed about what conservative care can and can't do, and as long as we re-examine and reimage at sensible intervals, waiting is a legitimate choice. This patient is the one who decided when it was time.
  • Mostly, yes. The dislocation rate with the direct anterior approach is low enough that most patients do not need the classic hip precautions (no bending past 90 degrees, no crossing legs, no rotating in). The few exceptions involve borderline anatomy or particular soft-tissue considerations. We discuss precautions individually.
  • It is a small sensory nerve that lies near the surgical window in the direct anterior approach. Stretch or pressure on it during surgery can leave a patch of numbness or tingling on the front-outside of the thigh. It does not affect strength or movement. In the published literature it occurs in a notable minority of anterior hips and resolves over weeks to months in most cases. It is the most common 'thing the patient didn't expect' after this procedure, so we mention it explicitly during consent.
