기존 보존치료에 반응하지 않는 ACL 점액성 변성에서 인대 내 스테로이드 주사는 어떤 효과를 보였을까?
82무릎 중 78무릎(95.1%)에서 통증이 개선됐습니다. 운동 제한이 있던 50무릎 중 49무릎에서 제한이 해소됐습니다.

이 연구가 확인한 것은 무엇인가요?
82무릎 중 78무릎(95.1%)에서 통증이 개선됐습니다. 운동 제한이 있던 50무릎 중 49무릎에서 제한이 해소됐습니다.
개별 환자의 치료 결정에 바로 적용할 수 있나요?
대조군이 없고 ROM은 진료 기록에 정성적으로 남긴 결과입니다. 추적 MRI가 없습니다. 원문에 제시된 6개월 이상 통증 완화 비율은 70.5%와 61.0%로 서로 달라, 이 비율을 확정된 결과로 제시하기 어렵습니다.

Sang Yoon Kim, Byung Sun Choi, Du Hyun Ro, Hyuk-Soo Han. Efficacy of Intraligamentous Steroid Injection in Pain Reduction and Knee Motion Improvement in Patients with Mucoid Degeneration of the Anterior Cruciate Ligament. Clinics in orthopedic surgery. 2026;18(4):658-665. doi:10.4055/cios25280.
BACKGROUND
This study assessed the efficacy and safety of fluoroscopy-guided intraligamentous steroid injections in managing mucoid degeneration of the anterior cruciate ligament (MDACL) in patients resistant to oral medication and intra-articular steroid injections.
METHODS
A retrospective review of 294 knees diagnosed with MDACL via magnetic resonance imaging between October 2014 and June 2023 was conducted. After applying exclusion criteria and excluding patients who were asymptomatic or showed improvement with conservative treatment, 82 knees were included in the final analysis. Intraligamentous steroid injections were performed under C-arm fluoroscopy by a single orthopedic surgeon. Clinical data collected included the duration of the pain-free period, patient-reported outcome measures (PROMs; pain numeric rating scale, the International Knee Documentation Committee subjective score, Lysholm score, and Knee Injury and Osteoarthritis Outcome Score), range of motion, and other radiological measures. Symptom recurrence rates were determined using the Kaplan-Meier survival analysis.
RESULTS
The average age at the time of injection was 64.0 years (range, 39-83 years), and the mean follow-up period was 19.5 months (range, 12-90 months). Pain improvement was noted in 78 of 82 knees (95.1%), with an average effect duration of 7.8 months (standard deviation, 9.1). Improvement of limitation of knee motion was observed in 49 of 50 cases (98.0%). Kaplan-Meier analysis indicated symptom recurrence rates of 19.5% at 3 months, 39.0% at 6 months, and 48.8% at 1 year. All PROMs significantly improved after injection for 6 months (p < 0.01) and then slightly declined. No patients reported post-procedure instability.
CONCLUSIONS
Fluoroscopy-guided intraligamentous steroid injection demonstrated short-term efficacy in relieving pain and improving knee motion in MDACL patients resistant to conventional treatments, although further studies are warranted to confirm these findings.
