Locked knee caused by intraarticular ganglion.

Intraarticular ganglion cyst arising from the cruciate ligament is difficult to diagnose by clinical symptom. In our case, Cyst attached anteriorly to posterior cruciate ligament, and limited both flexion and extension of knee. The cyst was excised in a piecemeal fashion arthroscopically. Knee pain and limitation in knee motion disappeared by the day after surgery. We hypothesize that reason of restriction of extension is impingement between anterior cruciate ligament and intracondylar, and reason of restriction of flexion is stimulation nerve ending in the synovial membrane stretched with knee motion.

Arthroscopy↗

Juvenile rheumatoid arthritis manifesting in only limping due to flexion contraction of the knee.

Juvenile rheumatoid arthritis (JRA) is a relatively uncommon condition. The damage to the cartilaginous tissue is often irreversible and responsible for much of the morbidity. Timely diagnosis and appropriate aggressive treatment of patients improve quality of life and outcome. A reported case of JRA is presented in which limping associated with flexion contraction of the knee developed without any systemic symptoms. Magnetic resonance imaging and arthroscopic examination were helpful with early diagnosis. Aspirin was effective. There have been no recurrence to date.

Arthritis, Juvenile↗

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.

Arthralgia↗

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.

Adipose Tissue↗

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.

Effects of basic fibroblast growth factor on the repair of large osteochondral defects of articular cartilage in rabbits: dose-response effects and long-term outcomes.

Articular cartilage possesses a limited capacity for self-renewal. The regenerated tissue often resembles fibrocartilage-like tissue rather than hyaline cartilage, and degeneration of the articular surface eventually occurs. The purpose of this study was to investigate the effect of basic fibroblast growth factor (bFGF) on the healing of full-thickness articular cartilage defects. bFGF (0, 10, 50, 100, 250, 500, or 1000 ng) was mixed with collagen gel and implanted into full-thickness articular cartilage defects drilled into rabbit knees. The repaired tissue was examined grossly and histologically, and was evaluated with the use of a grading scale at 4, 12, 24, and 50 weeks. At 4 weeks, treatment with 100 ng of bFGF had greatly stimulated cartilage repair both grossly and histologically in comparison with untreated defects (those filled with plain collagen gel). The average total scores on the histological grading scale were significantly better for the defects treated with bFGF than for the untreated defects. These improvements were evident as long as 50 weeks postoperatively, although slight deterioration was noted in the repaired cartilage. Immunohistochemical staining for type II collagen showed that this cartilage-specific collagen was diffusely distributed in the repaired tissue at 50 weeks. These findings suggest that bFGF may be a practical and important candidate for use in cartilage repair.
