Key Conclusions
If you are visiting from abroad, note that all of the data below comes from Korean-language platforms, and language support varies by clinic — an English-speaking clinic in Ansan cannot be assumed from these listings and must be confirmed by phone or on the clinic's booking page. Bring your passport or Alien Registration Card and your insurance details, and expect to book by phone, because the booking method for each of the five clinics is not described in the collected data.
Looking at review volume alongside the ratings that could be verified, 에이스병원 (Ace Hospital) and 클래스병원 (Class Hospital) stand out first. Ace Hospital has 1,069 Naver reviews, 2,741 blog reviews and 551 Kakao reviews, with a 4.8 rating on both Kakao and Google; Health Insurance Review & Assessment Service (HIRA) registration data lists 9 orthopedic specialists. Class Hospital has 858 Naver reviews, 2,369 blog reviews and 1,102 Kakao reviews, with 4.7 on Kakao and 4.9 on Google, and 3 orthopedic specialists. These figures alone cannot, however, rank the two hospitals' rotator cuff expertise or treatment outcomes. Confirm directly with the clinic before visiting whether rotator cuff consultation and testing are available and who will be handling your care.
How We Compared
We collected 4,047 Naver Place visitor reviews, 2,226 Kakao Map reviews and HIRA registration data, then compared the five selected clinics. The review counts per clinic on Naver, blog, Kakao and Google, the ratings that could be verified, the number of orthopedic specialists, and the opening hours and location information were used. Where a clinic's Naver or Google rating was not provided, it is marked "not available" rather than calculated. The average Kakao Map rating across the five selected clinics is 4.2, based on the summary provided. Reviews reflect individual visitors' experiences and do not guarantee treatment outcomes.
Clinic-by-Clinic Details
에이스병원 (Ace Hospital)
In the data provided, this clinic has the largest review volume: 1,069 Naver reviews, 2,741 blog reviews and 551 Kakao reviews. Its Kakao and Google ratings are 4.8 each, and HIRA registration data lists 9 orthopedic specialists. These numbers and reviews are reference points for comparison, not an indication of treatment results for rotator cuff conditions. The collected information does not state which clinicians handle shoulder rotator cuff cases specifically, nor does it list specialised treatment or surgery volumes.
"I came here for treatment with Dr. 오진철 (Oh Jin-cheol) — both the doctor and the nurses are kind and lovely!" (솜쥬르, October 21, 2026)
"The director and the nurses explained everything kindly, and I could get my tests done quickly, which was great. The hospital is big and clean, and having equipment that ordinary local clinics don't have really helped them assess my condition." (soouey, October 21, 2026)
The address is 경기 안산시 단원구 광덕대로 244 (244 Gwangdeok-daero, Danwon-gu, Ansan-si, Gyeonggi-do), listed as 844m from Exit 1 of 중앙역 (Jungang Station) on the Suin–Bundang Line. Hours are 09:00–18:00 Monday to Friday and 09:00–13:00 on Saturday. Sunday hours and lunch break were not provided, so check before visiting. Booking method and parking information are also absent from the collected data. Equipment registered includes 5 ultrasound imaging devices and 2 CT scanners, but ask the clinic whether shoulder imaging is available and whether it can be done the same day. If you want rotator cuff care, it is practical to first confirm who will see you, what examination and testing steps are involved, and whether an appointment is required.
클래스병원 (Class Hospital)
The data provides 858 Naver reviews, 2,369 blog reviews and 1,102 Kakao reviews, with a 4.7 Kakao rating and a 4.9 Google rating. HIRA registration lists 3 orthopedic specialists. Two MRI scanners, 1 CT scanner and 3 ultrasound imaging devices are registered, but owning equipment alone does not establish that rotator cuff imaging is performed or that the clinic specialises in it. The provided data contains no information on specialised shoulder rotator cuff care, so if that is what you need, check directly with the clinic about the medical staff and whether the relevant tests are available.
"I came in for treatment on a broken ankle and ended up impressed by how kind Dr. 이성민 (Lee Seong-min) was." (미남5252, October 21, 2026)
"They explained everything kindly, I received good treatment, and I'm coming back next week." (회사자연24, October 20, 2026)
The address is 경기 안산시 단원구 적금로1길 11 SR노빌리안 (SR Nobilian, 11 Jeokgeum-ro 1-gil, Danwon-gu, Ansan-si), 512m from Exit 1 of 고잔역 (Gojan Station) on the Suin–Bundang Line. The timetable provided shows a 24-hour emergency room every day of the week, but outpatient orthopedic hours need separate confirmation. Lunch break is also missing from the data. Booking, parking, Wi-Fi, a waiting area and separate men's and women's restrooms are listed as amenities. Do not confuse 24-hour emergency operations with outpatient service — confirm the registration cut-off time for shoulder care and the booking method before you go.
성모본정형외과의원 (Seongmo Bon Orthopedic Clinic)
The data provides 656 Naver reviews, 3,100 blog reviews and 387 Kakao reviews, and the Google rating is listed as 5. Naver and Kakao ratings and the HIRA orthopedic specialist count are not in the data, so they cannot be compared. Actual visitor reviews contain comments on explanations, staff manner and treatment experience, but they do not verify the effectiveness of rotator cuff care. The collected information does not present specialised rotator cuff services, imaging equipment or the responsible clinicians, so ask in advance whether the care you need is available.
"The doctor and the nurse were both so kind, and I was worried it would hurt but they made it completely painless, which was great. If I ever need an orthopedic clinic again, I'll only come here from now on!" (호두0120, October 16, 2026)
"They give only the treatment that's needed without over-servicing, and everyone is kind." (홍루이젠동탄호수공원, October 15, 2026)
The address is 경기 안산시 상록구 해양4로 26, 401~405호 (Unit 401–405, 26 Haeyang 4-ro, Sangnok-gu, Ansan-si, Gyeonggi-do). Hours are 09:00–20:00 on Monday and Thursday, 09:00–19:00 on Tuesday, Wednesday and Friday, and 09:00–14:00 on Saturday. Sunday hours and lunch break were not provided. Accessibility, booking method and parking information are also absent from the collected data. Some reviews mention waiting after booking, but that cannot be treated as the clinic's official booking policy. Confirming booking availability and parking guidance yourself, and asking about rotator cuff care and the testing plan before your consultation, will help you plan the visit.
선부365정형외과의원 (Seonbu 365 Orthopedic Clinic)
The data provides 922 Naver reviews, 425 blog reviews and 185 Kakao reviews. The Kakao rating is 4.1; Naver and Google ratings and the HIRA orthopedic specialist count are not in the data. Reviews mention kind service, a comfortable environment and reduced pain after treatment. These are individual experiences of the reviewers and cannot be generalised into rotator cuff treatment results. No information on specialised rotator cuff care or related imaging equipment was provided, so confirm shoulder consultation and testing availability before booking.
"It's big, the staff are kind, and they're thorough!" (lollolfama, October 19, 2026)
"The doctor looked at me carefully and kindly, my pain dropped a lot after treatment, and everyone is so kind that I'll come to this orthopedic clinic from now on." (송송이591, October 17, 2026)
The address is 경기 안산시 단원구 삼일로 310 3층, 서울프라자 (3F Seoul Plaza, 310 Samil-ro, Danwon-gu, Ansan-si), listed as 159m from Exit 3 of 부역 (Buyeok Station) on the Seohae Line. Hours are 09:00–20:00 Monday to Friday, 09:00–14:00 on Saturday and 09:00–13:00 on Sunday. Weekday evening and Sunday hours are listed, but lunch break is not in the data. Booking, parking, Wi-Fi, a waiting area, simple payment and separate men's and women's restrooms are listed as amenities. Confirm actual parking availability and conditions before you arrive. If you are considering a late visit, it is better to ask first about the same-day registration cut-off and the hours during which rotator cuff care is available.
이진수정형외과의원 (Lee Jin-su Orthopedic Clinic)
The data provides 542 Naver reviews and 243 blog reviews; the Kakao rating is 3 and the Google rating is 3.7. Kakao shows 1 review and Google shows 0 reviews, so the rating and the review count need to be read together. HIRA registration lists 1 orthopedic specialist, and 1 ultrasound imaging device, 1 bone density scanner and 1 general X-ray unit are registered. Whether the clinic specialises in rotator cuff care is not confirmed in the data.
"Everyone is kind and the physical therapy works well." (ksa, May 28, 2026)
"The doctor treats you well and it feels comfortable." (해바라기282, August 13, 2025)
The address is 경기 안산시 단원구 광덕대로 168 신화타운 (Sinhwa Town, 168 Gwangdeok-daero, Danwon-gu, Ansan-si), and no public transport access information is available. Hours are 09:00–18:00 on Monday, Tuesday, Wednesday and Friday, 09:00–13:00 on Thursday and 08:30–12:30 on Saturday. Sunday hours and lunch break were not provided. Booking and parking information are also missing from the data. Some reviews mention frustration with phone handling while others describe kind service. Check phone reachability and booking availability before visiting, and ask whether the imaging you need, such as ultrasound, is available and what the rotator cuff consultation process involves.

Checklist for Choosing a Shoulder Rotator Cuff Clinic
- Whether rotator cuff care is offered — ask whether the clinic consults on shoulder pain and suspected rotator cuff problems.
- Who will treat you — confirm with the clinic who will handle your case and whether they are an orthopedic specialist.
- Whether testing is available — check which imaging can be done on site and whether any test requires going elsewhere.
- Equipment and process — even when equipment is registered, ask whether it can actually be used for your symptoms.
- Booking and registration cut-off — confirm whether an appointment is required and when same-day registration closes.
- Hours and lunch break — re-check the published hours, lunch break and any closures on the day you plan to visit.
- Treatment options and explanations — check that you can have the treatment options based on your test results, and the purpose of each, explained to you.
- Cost and insurance coverage — costs per test or treatment and insurance coverage depend on your personal situation; confirm with the clinic and your insurer.
- Follow-up and treatment schedule — if further visits are needed, ask about the expected interval and how to book.
- Transport and parking — confirm public transport access and parking availability and conditions before you set out.
Warning Signs to Watch For
- If you are pushed to decide on a specific treatment immediately, without an explanation of the examination or test results, ask again about the goal of that treatment and the alternatives.
- If a clinic promises a treatment effect or a cure outright without checking your individual condition, ask what that claim is based on and what its limits are.
- If you are not told the costs and the process for tests and treatment, confirm item-by-item costs and what you are consenting to before proceeding.
- Do not judge whether a clinic is right for rotator cuff diagnosis and treatment from online ratings or reviews alone. Reviews are individual experiences and do not replace a clinician's judgment.
Frequently Asked Questions
Which clinic in Ansan has the most reviews for shoulder rotator cuff care?
Adding together the Naver, Kakao and Google review counts provided, 클래스병원 (Class Hospital) is highest at 1,960. That figure excludes blog reviews, and a higher review count does not mean better treatment results or better rotator cuff care.
Which clinic has the most orthopedic specialists?
Based on HIRA registration data, 에이스병원 (Ace Hospital) has 9, 클래스병원 (Class Hospital) has 3 and 이진수정형외과의원 (Lee Jin-su Orthopedic Clinic) has 1. The specialist count for 성모본정형외과의원 (Seongmo Bon Orthopedic Clinic) and 선부365정형외과의원 (Seonbu 365 Orthopedic Clinic) is not in the provided data.
Can the data tell me whether a clinic specialises in rotator cuff injuries?
No. The provided data contains no information on whether any of the five clinics specialises in rotator cuff care, nor on related case volumes or treatment outcomes. Ask the clinic before visiting about rotator cuff consultation availability, who will be treating you, and the testing process.
Which clinics have MRI or ultrasound?
HIRA registered-equipment data lists 2 MRI scanners and 3 ultrasound imaging devices at 클래스병원 (Class Hospital), 5 ultrasound imaging devices at 에이스병원 (Ace Hospital), and 1 ultrasound imaging device at 이진수정형외과의원 (Lee Jin-su Orthopedic Clinic). Registered equipment alone cannot tell you whether a particular test can be done the same day or whether you personally need it, so confirm with the clinic.
Which clinics can I visit in the evening or at the weekend?
According to the timetables provided, 성모본정형외과의원 (Seongmo Bon Orthopedic Clinic) is open until 20:00 on Monday and Thursday, and 선부365정형외과의원 (Seonbu 365 Orthopedic Clinic) until 20:00 Monday to Friday. Seonbu 365 Orthopedic Clinic also lists Sunday hours of 09:00–13:00. 클래스병원 (Class Hospital) only provides 24-hour emergency room information, so its outpatient hours need separate confirmation.
Do any of these Ansan clinics have English-speaking staff?
The collected data does not include language support information for any of the five clinics — no English-speaking doctor, interpreter service or international patient department is listed, and all of the reviews quoted here are in Korean. Language support therefore has to be confirmed directly: call the clinic or check its booking page and ask whether an English-speaking doctor is available on the day you want to visit. If you need interpretation, arrange it before your appointment rather than at the front desk.
Final Notes
If you want to start with review volume and published ratings, 에이스병원 (Ace Hospital) and 클래스병원 (Class Hospital) are the obvious candidates to compare. Choose according to the criteria that matter to you — orthopedic specialist count, location, opening hours — but remember that the collected data does not confirm rotator cuff specialisation for any of the five clinics. The cause of shoulder pain and the care required differ from person to person, so decisions should be based on a clinician's examination and explanation. This article summarises the reviews and institutional registration data provided and does not replace diagnosis or treatment. Confirm opening hours, booking and test availability with the clinic before you visit.
