What does osteoarthritis of the hip mean?
The femoral head is the ball at the top of the thighbone; the acetabulum is the socket in the pelvis[1]. Articular cartilage covers their joint surfaces[1]. In osteoarthritis, cartilage loss can accompany joint-space narrowing and bone spurs called osteophytes[1].
Hip arthritis is a broader label than hip osteoarthritis[2]. The American Association of Hip and Knee Surgeons (AAHKS) distinguishes osteoarthritis from rheumatoid arthritis, an inflammatory condition involving the immune system and joint lining[2].
The wider osteoarthritis guide covers the condition across joints. This page keeps the discussion specific to the hip.
Where is hip arthritis pain felt?
AAOS describes groin pain as a common location, with pain also reported in the thigh, buttock or knee[1]. Stiffness after rest and reduced hip movement are other described features[1].
Pain location is information to bring to an appointment, not a diagnostic test[2]. AAHKS explicitly notes that hip pain has diagnoses other than osteoarthritis[2].
How is hip osteoarthritis assessed?
AAOS describes a medical history, examination of movement and walking, and possible X-rays[1]. Joint-space narrowing, bone changes and osteophytes are among the imaging findings it describes[1].
For your appointment, record where the discomfort occurs, when it began, which activities are difficult and which prior images or reports are available. Ask the clinician which findings support the diagnosis and whether another source of pain needs investigation.
The AAOS hip-osteoarthritis clinical practice guideline was published December 1, 2023[3]. Its stated population is adults already diagnosed by a trained healthcare provider and undergoing treatment; it is not a self-diagnosis questionnaire[3].
What did hip PRP studies actually measure?
These are two selected original reports, not a systematic review. Their study designs and limitations are reported separately.
Dallari et al., 2016: three active injection groups
This randomized study assigned 111 adults with hip osteoarthritis to PRP (44), PRP plus hyaluronic acid (31), or hyaluronic acid (36)[4]. Injections were ultrasound-guided[4]. Researchers assessed pain and function at 2, 6 and 12 months; the author abstract describes blinded outcome assessors and collectors[4].
At six months, reported mean pain scores on a 100-mm visual analog scale were 21 for PRP, 35 for the combination and 44 for hyaluronic acid[4]. The abstract reports a WOMAC difference favoring the PRP group at two and six months, but not at twelve months[4]. There was no saline-placebo arm[4]. These are findings from the original abstract, not a claim that PRP will produce the same result for a reader[4].
Topaloglu et al., 2024: PRP compared with saline
This hip-osteoarthritis study compared ultrasound-guided PRP with saline and followed participants for six months[5]. Its methods mention 78 included patients, while the final analysis describes 60 completers, 30 per group[5]. Participants and assessors were blinded; the injecting physician was not[5]. Both groups also received individualized rehabilitation programs[5].
Table 2 reports six-month activity-pain scores of 5.46 for PRP and 4.70 for saline, with a between-group P value of 0.363[5]. The authors reported no statistically significant between-group difference in that outcome[5]. The small analyzed sample and six-month follow-up limit what this study addresses; the analysis count should not be mistaken for all initially included patients[5].
What should I ask before discussing an injection?
Ask which study supports the proposed procedure for the hip, what preparation was studied and what the comparison group received. The 2016 study compared three active preparations; the 2024 study included a saline group and rehabilitation in both arms[4][5]. These designs answer different questions[4][5].
Ask the provider to identify the proposed material, the clinician performing the procedure, whether imaging guidance is planned, and what follow-up is included. Request an itemized written quote separating consultation, imaging, procedure and follow-up fees. This checklist is not an instruction to undergo an injection.
Bring questions about non-procedure options and specialist assessment as well. This page does not choose a treatment, set an injection schedule or interpret a personal scan.
Where can I compare PRP clinic listings?
In Regenerated.com's September 2026 export of 9,042 US clinic records, 2,082 list PRP across 48 states plus Washington, DC. Source: the directory's dated clinic export, independently recounted for this page. This measures category coverage, not a count of clinics confirmed to provide hip injections. It is not a recommendation to use PRP for hip osteoarthritis.
If PRP is already part of a discussion with your clinician, compare PRP clinic listings. Geographic examples include PRP clinics in Birmingham, Alabama and PRP clinics in Glendale, Arizona. Confirm the specific service directly with the provider.
Directory inclusion is not an endorsement. The listing and the consultation answer different questions: the directory supplies comparison information, while the clinician assesses your individual circumstances.
