Wellton Hospital Achieves 0% Dislocation Rate After Hip Replacement Surgery
Data confirmed across three consecutive quarters in 2025 by Korea's Health Insurance Review & Assessment Service — covering 277 patients with zero post-operative dislocation incidents.
Verified by Korea Health Insurance Review & Assessment Service (HIRA) quarterly hip replacement analysis data. Total of 277 patients — zero dislocation events recorded.

Quarters
Incidents
Total hip arthroplasty (THA) is a procedure that dramatically improves a patient's walking ability and quality of life, but both patients and surgeons share a common concern: post-operative dislocation. Against this backdrop, Wellton Hospital has recorded a dislocation rate of 0.000% (zero cases) in the "dislocation within 3 months of surgery" indicator across all three quarters of 2025, as verified by Korea's Health Insurance Review & Assessment Service (HIRA) quarterly hip replacement analysis data.
The results cover Q1 (107 patients), Q2 (71 patients), and Q3 (99 patients) — totalling 277 patients with no dislocation events recorded during the critical early recovery period. This is particularly significant given that a higher surgical volume typically introduces more variables and increases the statistical probability of complications.
Why Dislocation Prevention Matters
According to Wellton Hospital, dislocation prevention in hip replacement surgery is critical because a dislocation is a complication that almost always requires revision surgery. When the prosthetic femoral head slips out of the acetabular cup, the patient experiences severe pain and becomes unable to walk, requiring emergency care. Once dislocated, the surrounding muscles and ligaments are damaged, raising the likelihood of recurrent dislocations — the leading cause of highly complex revision procedures to replace the entire implant.
Beyond the physical consequences, fear of dislocation can prevent patients from engaging actively in post-operative rehabilitation, delaying their return to daily life.
- Severe acute pain and immediate loss of mobility
- Emergency room visit required
- Damage to surrounding muscles and ligaments
- High risk of becoming habitual (recurrent) dislocation
- May necessitate complex revision (implant replacement) surgery
- Psychological barrier that slows rehabilitation progress
The Surgical Technique: Muscle & Tendon-Preserving Minimally Invasive Approach
Wellton Hospital attributes its results to a "muscle and tendon-preserving minimally invasive surgical technique." Rather than cutting the external rotator muscles around the hip — including the piriformis — the surgical team retracts them to create the necessary workspace and then restores them fully after implanting the prosthesis.
Because the muscles and tendons remain intact, they provide firm support around the artificial joint, minimising dislocation risk. This structural stability is further enhanced by the precise selection and organic fit of prosthetic components tailored to each patient's anatomy.
"Dislocation is a complication that can cause patients tremendous suffering and disappointment. The fact that all 277 patients returned safely to their daily lives is the most rewarding outcome we could ask for as medical professionals. Based on these surgery results — confirmed through HIRA analytical indicator data — we will continue setting the standard for a safe hospital that patients can trust." — Song Sang-ho, Director, Wellton Hospital
Background: Wellton Hospital's Hip Surgery Expertise
Wellton Hospital holds extensive clinical experience in high-complexity hip surgery and has long pursued data-driven quality management to improve patient satisfaction. The hospital is located at the Wellton Mediplex building directly in front of Magok Naru Station (Exit 1), Gangseo-gu, Seoul, with convenient access via Airport Railroad and Metro Line 9.
The latest HIRA-verified data reinforces the hospital's standing as a nationally recognised institution for joint surgery, offering patients evidence-based reassurance when choosing where to undergo hip replacement.
고관절 인공관절 치환술은 수술 후 환자의 보행 능력과 삶의 질을 획기적으로 높여주는 치료법이지만, 환자와 의료진 모두에게는 '탈구(Dislocation)'라는 부작용에 대한 우려가 존재한다. 이러한 가운데 웰튼병원이 건강보험심사평가원(이하 심평원)의 평가 지표에서 2025년 1~3분기 연속 고관절 수술 후 탈구(Dislocation)율 0%를 기록했다.
웰튼병원 송상호 병원장은 "탈구는 환자에게 큰 고통과 좌절감을 줄 수 있는 합병증이기에, 277명의 환자 전원이 건강하게 일상으로 복귀했다는 점이 의료진으로서 가장 보람된 성과"라며 "심평원 분석지표 데이터를 통해 확인된 수술 결과를 바탕으로, 앞으로도 환자들이 믿고 찾을 수 있는 안전한 병원의 기준을 만들어가겠다"고 전했다.
