The present study describes a case of leg lymphedema due to iliopectineal bursitis associated with rheumatoid arthritis (RA), which was satisfactorily controlled by surgery and combination therapy with methotrexate (MTX) and tacrolimus. A 68-year-old male, who had a six-year history of RA, developed an iliopectineal bursa associated with destruction of the hip joint. The mass gradually increased in size, and there was swelling in his right lower extremity. The patient was subsequently hospitalized with increasing right hip pain and leg edema. A colorless transparent lymph fluid leaked from his leg, and leg lymphedema was thus diagnosed. The patient also had a 20-year history of myelodysplastic syndrome. Therefore, the extensive or total resection of the bursa was considered to be too invasive, so a partial bursal excision was performed via an anterior approach. Following the partial bursal excision, total hip arthroplasty (THA) was performed using the Hardinge approach. The leg lymphedema disappeared following the surgery, and the iliopectineal bursa was no longer enlarged. MTX and tacrolimus were postoperatively administered to strictly control the RA. The RA was subsequently well controlled, without any increases in the levels of inflammatory markers, such as C-reactive protein and matrix metalloproteinase-3. This case demonstrated that iliopectineal bursitis was resolved following THA, without complete excision of the intrapelvic bursa, and that strict RA control led to a good clinical course without recurrent inflammation of the bursa. Similar procedures may be beneficial in other patients contraindicated for resection of the entire bursa.

The Statak is a suture anchor device used for attaching soft tissue to bone. This is a report on six knees in which this device was used to repair partial avulsion of the patellar ligament during total knee arthroplasty (TKA). The six patients were all women. The average age of the patients was 69 years. The diagnosis was osteoarthritis in three patients, rheumatoid arthritis in two, and steroid arthropathy in one. Three of the operations were revision arthroplasties. In all six cases, approximately half of the patellar ligaments were accidentally detached from the tibial tubercles during surgery, and were repaired using the Statak devices. The average length of follow-up was 3 years. The Knee Society knee score improved from an average of 15 points preoperatively to 87 points at the latest follow-up. The average total range of motion measured 104° before surgery and 108° at the latest follow-up. Three of the six knees operated on had no extensor lag. The suture anchor simplifies the secure fixation of the ligament to bone. The procedure can be performed easily and quickly. In our opinion, the Statak device has proven itself to be effective for the repair of partial patellar ligament avulsion during TKA.
