How Do I Choose Safe Hip Exercises After Replacement or Arthroscopy?

When can I start exercising after hip replacement surgery?

After hip replacement, exercise can start shortly after surgery, but only within the surgeon and physical therapist's plan. The American Academy of Orthopaedic Surgeons exercise guide states that patients may begin approved exercises in the recovery room, including ankle movements and gentle muscle activation.

That early start does not mean an early workout routine. Hospital for Special Surgery describes the first 2 to 4 weeks as a recovery-focused period centered on walking and functional exercises learned in physical therapy. That distinction is useful: movement can be part of recovery while a demanding exercise session is still premature.

The major fork in the road is the operation itself. AAOS explains that full weight bearing after a replacement may be immediate or delayed for several weeks, depending on the implant and individual instructions. For arthroscopy, the evidence is even less uniform: a 2023 systematic review in the Journal of Hip Preservation Surgery found that 91.7% of reviewed protocols used some protected weight bearing, but concluded that comparative evidence was insufficient to recommend one universal restriction.

In plain English, a calendar can organize questions, but it cannot overrule the operative plan. Ask the surgeon or therapist what procedure was performed, what weight-bearing status applies, which motions are limited, and what symptom changes mean the current dose of activity is too high.

Which hip exercises are safe in the first few weeks after surgery?

In the first few weeks, safe exercises are the ones specifically permitted for the procedure and current restrictions, usually gentle walking, mobility, and muscle activation rather than self-selected strengthening. AAOS lists ankle pumps, ankle rotations, bed-supported knee bends, buttock contractions, hip abduction, quadriceps sets, and straight-leg raises among early total-hip-replacement exercises, with several prescribed as 10 repetitions for 3 to 4 daily sessions in its guide.

Those details are not a transferable prescription for every hip operation. The Massachusetts General Hospital arthroscopy protocol, for example, prohibits active straight-leg raises in its early phase and continues to avoid them for 8 weeks. The same movement can therefore be suitable in one rehabilitation plan and restricted in another. Procedure labels alone do not settle the question.

Use symptoms as a second filter after the written restrictions. The Massachusetts General Hospital protocol says to avoid symptom provocation during walking, daily activities, and therapeutic exercise, as well as post-activity soreness. Hospital for Special Surgery similarly says sudden or persistent sharp pain, especially with increased swelling, suggests the hip has been overtaxed and activity should be reduced.

Expected swelling also needs context. AAOS says moderate to severe swelling can occur in the first few weeks after hip replacement, while mild to moderate swelling can persist for 3 to 6 months; new or severe swelling should be reported because it can signal a blood clot. AAOS also identifies increasing wound redness, tenderness, swelling, or drainage; persistent fever above 100 degrees; and increasing pain at rest and with activity as reasons for prompt medical contact.

This is a better decision rule than trying to be tough or trying to eliminate every ache. Pain that changes walking, swelling that increases, or symptoms that remain the next day are useful information for the clinical team. A quiet, tolerable response to the approved plan is the more relevant milestone.

Is walking enough exercise during hip replacement recovery?

No. Walking is an important part of hip replacement recovery, but AAOS explicitly states that it is not a substitute for physical-therapy-prescribed exercises. Walking rebuilds tolerance for everyday movement; the prescribed exercises address the specific mobility and muscle-control work that walking may not cover.

AAOS begins walking with 5 to 10 minutes, 3 to 4 times per day, and describes progression to 20 to 30 minutes, 2 to 3 times per day as strength and endurance improve. Hospital for Special Surgery gives the same practical caution in different terms: do not jump from one block of walking to 20 blocks. A modest increase that the hip tolerates is more informative than one ambitious day followed by a flare.

Assistive-device changes are also functional, not cosmetic. AAOS says a person may move to one crutch or a cane when they can stand and walk for more than 10 minutes without putting weight through the walker or crutches. In the Massachusetts General Hospital arthroscopy protocol, pain during walking is a reason to continue with one crutch and wean more gradually, even where the plan otherwise anticipates weaning by 6 to 8 weeks.

Later exercise still needs clearance. AAOS discusses gradually adding stationary-bike resistance at about 4 to 6 weeks after replacement, beginning with 10 to 15 minutes twice daily and building toward 20 to 30 minutes 3 to 4 times weekly. The Massachusetts General Hospital 2023 arthroscopy protocol places advanced rehabilitation at 12 to 16 weeks and permits treadmill running at 16 weeks only with surgeon clearance. These are different pathways, not competing promises.

For a broader, non-postoperative baseline once the clinical team has cleared general training, What Is a Safe At-Home Strength and Mobility Routine for Adults Over 65? can help frame how mobility and strength work fit together. During surgical recovery, however, the operative plan remains the governing document. Keep the next step small, track the hip's response during and after activity, and bring that record to physical therapy.
