A giant rheumatoid nodule.

Subcutaneous rheumatoid nodules occur commonly in advanced cases of rheumatoid arthritis and are the most common extra-articular lesion of this disease. We present a case of a very unusual giant rheumatoid nodule that developed on the lateral side of a knee. The case was devoid of systemic symptoms of arthritis and the lesion was limited to a rheumatoid nodule. The nodule was successfully treated by surgical excision. However, other new nodules developed in her hand. Her clinical course has not been satisfactory.

Patellar tendon rupture and marked joint instability after total knee arthroplasty.

BACKGROUND: Patellar tendon rupture is a rare complication of total knee arthroplasty (TKA). Multiple repair methods have been described in the literature. METHODS: A 66-year-old woman suffered a patellar tendon re-rupture and marked joint instability within 6 months after revision TKA. She underwent re-revision TKA and extensor mechanism reconstruction with femoral quadriceps tendon and augmentation by a Leeds-Keio ligament. RESULT: It was fairly difficult to acquire a satisfactory range of motion as well as gain in knee extension capacity by eliminating the extension lag. CONCLUSION: Patellar tendon ruptures after TKA should be repaired as soon as they are recognized.

Meniscal ossification.

Meniscal ossicles are rare in the human knee. We present one case. A 57-year-old taxi driver complained of right knee pain and swelling with radiographic findings of a meniscal ossicle. Arthroscopic inspection showed a degenerative and horizontal tear and calcium deposit at the middle and posterior thirds of lateral discoid meniscus. His lateral discoid meniscus, containing the ossicle, was removed. He was asymptomatic at a 3-year follow-up.

Snapping knee caused by intra-articular tumors.

Locking of the knee can present with no history of antecedent injury. We identified impingement of intra-articular tumors in 2 cases. Intra-articular tumors are relatively rare. Mechanical symptoms were present in both cases. On physical examination, there was a palpable mass at the medial region of the patellofemoral joint. The interior had been replaced mainly by amorphous necrotic tissue. The definite diagnosis of a soft-tissue mass of the knee could not be made on histologic examination.

A giant ganglion cyst that developed in the infrapatellar fat and partly extended into the knee joint.

Ganglion cysts of the knee joint usually present near the lateral meniscus. Their size varies, and they may be encased in single or multiple capsules. Few case reports on ganglion cysts of the knee joint have been reported. We report a giant ganglion cyst that developed in the patellar fat and partly extended into the joint. The ganglion cyst was exposed in the meniscosynovial junction and was electrically evaporated at the anterior horn. No recurrence has occurred to date, and the patient has returned to his previous level of activity.
