This paper describes a longitudinal patellar-splitting approach to the knee that includes provision for accurate reconstruction. Our in vitro experiments showed that patellofemoral kinematics and length-change patterns of specific bands of the peripatellar retinacula were not changed significantly by opening and closing the knee via the transpatellar approach. This surgical approach will be use...

BACKGROUND Recurrent dislocation of the patella in patients with below knee amputation is a known entity. Abnormally high-riding patella (patella alta) and medial patellofemoral ligament insufficiency in these patients predisposes them to patellar instability. The established treatment of this problem is surgical realignment. CASE PRESENTATION A 25 year old male patient with bilateral below k...

Patellar dislocation is a well-recognized major complication after total knee arthroplasty (TKA). Treatment of this injury is determined according to the cause of the dislocation. In particular, proximal realignment, distal realignment, and lateral retinaculum release are options if patellar instability is not caused by prosthetic malposition. Here we report a case of patellar dislocation follo...

Arthroscopic reconstruction of the anterior cruciate ligament (ACL) using the middle third of the patellar tendon is an effective method for treating ACL insufficiency. Donor site morbidities are usually mild. This article presents a case of simultaneous patellar fracture and patellar tendon avulsion that occurred 8 weeks after this operation. Such a case has rarely been reported. Theoretically...

Joint squeaking has classically been described after total hip arthroplasty using a ceramic-on-ceramic bearing surface. This phenomenon has also been found to occur after total knee arthroplasty and can be associated with patient concern and dissatisfaction. However, it has not been described in the postsurgical native knee. We present 2 cases of knee squeaking after medial patellofemoral ligam...

ligament (ACL) injury are common injuries and can lead to devastating consequences if not treated appropriately. Their mechanism of injury is similar, namely, a valgus twisting injury as a result of sudden non-contact deceleration. Those at risk also share similar epidemiological and anatomical characteristics; they tend to be female, have ligamentous laxity, and be young, active adults, with d...
