A recent article discussed changes in soft tissue seen on MRIs over time with patients implanted with metal-on-metal modular stemmed prostheses and hip resurfacings. The median implantation time was 7 years. The authors described the muscle atrophy and pseudotumor formation that develops as part of […]
