Percussive vs. Gentle Massage for Recovery After Hip Replacement

Many people who have hip replacement surgery through a "bikini incision" on the front of the hip (anterior approach) develop numbness, tingling, burning, or tightness in the front and side of the thigh afterward. This happens because a small nerve near the incision can get irritated during surgery. For most patients these symptoms fade over time, but for some they can last for months or longer. This study is testing whether a simple, at-home self-care routine can help these symptoms improve faster. Patients will be randomly assigned to one of two groups: one group will use a handheld percussive massage device (like a massage gun) on the thigh twice a day, and the other group will do gentle hand massage on the same areas, for the same amount of time, twice a day. Both routines take about 5 minutes and are done every day for 6 weeks after surgery. Neither device use nor massage is applied directly on or near the surgical incision. The researchers want to find out whether the massage device works better than gentle hand massage for improving hip pain and function, reducing numbness and tingling, and improving sleep and comfort during recovery. Participants will complete short questionnaires and daily logs, with follow-up visits at 6 weeks and 3 months after surgery.
