Objectives: Several patients experience chronic pain after total knee arthroplasty (TKA), with the source of postoperative pain attributed to intra- and extra-articular factors. This study focused on the proximal tibia with either the Pes anserinus (PA) or around Gerdy's tubercle (GT) as the most common site of extra-articular pain.
Methods: This prospective study included 270 patients (360 knees) with advanced varus osteoarthritis (OA) of the knee scheduled for primary TKA and the patient population comprised 289 women and 71 men with a mean age of 74.
Article Synopsis
- The study investigates how new antirheumatic drugs affect the characteristics of lymphoproliferative disorder (LPD) in rheumatoid arthritis (RA) patients, using data from 53 hospitals in Japan between 1999 and 2021.
- A total of 752 patients with RA-associated LPD were compared to 770 with sporadic LPD, revealing notable differences in their clinical features and the impact of various drug combinations.
- The findings suggest that medications taken before LPD onset may alter its characteristics, and recommend tocilizumab (TCZ) as a better treatment option after LPD has developed.
Case: Marked varus or valgus hindfoot deformities in 3 patients with ankle osteoarthritis or rheumatoid arthritis were treated by corrective surgery using total ankle arthroplasty or distal tibia oblique osteotomy. All cases achieved not only sufficient correction and satisfactory clinical/radiographic hindfoot improvement but also improvements in both knee alignment and function.
Conclusion: Corrective surgery for hindfoot deformity can potentially change or improve ipsilateral knee alignment and function, representing an unexpected benefit of hindfoot realignment.
Article Synopsis
- A 71-year-old woman developed a skin ulcer from an abscess around her tibia, linked to an infection 11 years post knee surgery.
- Magnetic resonance imaging and biopsies revealed a unique fibrous abscess around the tibia caused by methicillin-resistant bacteria.
- After extensive surgical treatment, including debridement and skin grafting, the patient recovered fully and remained infection-free for two years, successfully walking without assistance.
