Post-Operative Aneurysm of the Descending Genicular Artery Presenting as a Pulsating Haemarthrosis of the Knee

Abstract

1. A case of traumatic aneurysm of the descending genicular artery complicating elective operation on the knee joint is reported. 2. The aneurysm was mainly intra-articular, presenting as a pulsating haemarthrosis soon after operation. 3. The pathogenesis, symptomatology, diagnosis and management are briefly discussed.

Descending genicular artery injury following transient lateral patellar dislocation

“…10 DGA injuries have been rarely reported as a result of knee surgical procedures, such as hamstring anterior cruciate ligament reconstruction, 3 replacement surgery, 4 arthroscopy, 5 and arthrotomy with synovectomy. 6,7 Arthroscopic portals, 4,6 placement of active drains, 5,7 and direct lesion during operative exposures 8 are the main iatrogenic causes of DGA lesion. The MPFL originates from the adductor tubercle and inserts on the superomedial patellar surface.…”

“…Transient lateral patellar dislocation (TLPD) is common in young and active patients as a consequence of low-energy traumas in sports and physical activity and may be complicated by patellofemoral chondral lesions as well as damage to the medial patellar stabilizers. 1,2 Injuries of vessels supplying medial capsular ligamentous structures of the knee have been rarely described following knee surgical procedures [3][4][5][6][7][8] and trauma. 9 We report a case of descending genicular artery (DGA) injury after a TLPD requiring an urgent angiographic coil embolization.…”

Early complication after total knee arthroplasty in a haemophilia A patient

“…In such cases, surgical intervention and wound inspection is required. There are few reports on complications in the form of a postoperative pseudoaneurysm or persistent joint or soft tissue haematoma [7,[10][11][12][13][14][15]. The recommended procedure is arteriography with embolisation of the injured vessel or surgical wound inspection and closure of the injured vessel under direct vision.…”

Pseudoaneurysm of the Medial Superior Genicular Artery after Arthroscopic Partial Meniscectomy

“…Most pseudoaneurysms have involved the popliteal arteries after knee arthroscopy. 2 , 3) Published reports suggest that the affected arteries are the lateral inferior genicular artery, 3 , 6) the descending genicular artery, 3 , 7) and the recurrent anterior tibial artery. 4) Pseudoaneurysm of the medial superior genicular artery has been reported at the previous superomedial portal site after arthroscopy.…”
