Knee Arthroplasty in Klippel-Trénaunay Syndrome with 3-Dimensional-Printed Patient-Specific Instruments: A Case Report.

CASE: Using a multidisciplinary team approach, a cemented posterior-stabilized total knee arthroplasty was performed using 3-dimensional-printed patient-specific instruments (PSI) in a 34-year-old man with symptomatic end-stage knee osteoarthritis secondary to Klippel-Trénaunay syndrome (KTS). At 1-year follow-up, the patient was able to walk without pain and return to work.

CONCLUSION

Knee arthroplasty is rare in patients with KTS. Compared with traditional instrumentation, PSI provides the benefit of minimal tissue dissection which can be advantageous in patients with altered anatomy such as KTS. Multidisciplinary cooperation is vital in terms of dealing with multiple comorbidities in KTS.
