Clinical efficacy of unicompartmental knee arthroplasty on limb swelling, pain, and functional rehabilitation in knee osteoarthritis patients

Compared with total knee arthroplasty, UKA demonstrates better short-term outcomes in relieving pain, reducing swelling, and promoting functional recovery in patients with knee osteoarthritis. These findings support UKA as an effective option for appropriately selected patients. However, the study is limited by its single-center design and short-term follow-up.
