Case 01
Case 01 — Knee Osteoarthritis Grade II (responder)
- Patient profile
- Female, 58 years old (initials M.R.). Comorbidities: well-controlled hypothyroidism (Hashimoto, levothyroxine), BMI 27. Right-knee dominant pain for 4 years, conservative management exhausted (NSAIDs, physiotherapy, intra-articular hyaluronic acid). Recreational walker, motivated to avoid arthroplasty.
- Presentation & baseline
- MRI confirmed bilateral grade II tibiofemoral chondropathy with small focal grade III lesion on medial femoral condyle. Baseline WOMAC total 58/96, pain subscale 14/20, Numeric Rating Scale (NRS) for pain 7/10 at rest, 9/10 with stairs. CRP 4.2 mg/L (mildly elevated). Walked < 1 km before pain forced rest.
- Treatment protocol
- Combined intravenous + intra-articular mesenchymal stem cell (MSC) protocol from a COFEPRIS-certified umbilical-cord-derived cell bank. Single IV infusion of 100 million MSCs, plus two right-knee intra-articular injections of 30 million MSCs each, spaced 4 weeks apart. Adjunct: oral collagen peptides and a 12-week guided exercise plan led by our physical-rehab team.
- Outcomes at follow-up
- At 6 months: WOMAC total 32/96 (−45%), pain subscale 6/20, NRS rest 2/10, stairs 4/10. CRP 1.8 mg/L. Walking distance > 3 km without pain interruption. At 12 months: improvements largely sustained (WOMAC 34/96, NRS rest 3/10) with mild seasonal flare in month 9 that resolved with rehab. At 24 months: WOMAC 38/96, patient continues recreational walking 4x/week. No need for arthroplasty referral.
- Honest assessment
- Responder. Profile fit the published candidacy literature (grade II-III, BMI < 30, motivated, intact muscle tone). Sustained benefit at 24 months. Honest caveat: the patient's strong adherence to the rehab plan likely contributed as much as the cellular component; outcome cannot be attributed to MSCs in isolation.
