Abstract
Traumatic bilateral patellar tendon rupture (BPTR) is a rare injury with low levels of clinical suspicion, especially in young adults. Since early diagnosis of the BPTR is the cornerstone of a successful management, BPTR reports are valuable as they raise awareness of the careful clinical and radiologic workout in similar cases. Here, we present a case of BPTR in a 34-year-old male following a motorcycle accident. At the emergency department, the necessary examinations including clinical, physical, and radiologic tests were performed and BPTR was diagnosed accordingly. The patient underwent reconstruction surgery the day after the injury. At the last follow-up, the patient was able to perform active straight leg raise with 130° flexion and no extension lag. The superior results of BPTR reconstruction in this report further emphasize the importance of early diagnosis and repair of BPTR. Active straight leg raise test is necessary to perform for all patients with a history of an eccentric load of the knee extensor mechanism, and if positive, extensor mechanism rupture should be strongly suspected.

Abstract
Introduction: Patellar dislocation is a relatively common injury. However, in rare circumstances along with dislocation of the patella, some types of fractures occur, making the treatment challenging and difficult.

Abstract
Background: Management of patellar maltracking during primary TKA is of considerable importance. Lateral release, which is generally performed for this purpose, is associated with several complications.
Objectives: In this study, we aimed to evaluate the role of partial lateral facetectomy in tracking the patella in Total Knee Arthroplasty (TKA).
Methods: In a retrospective study, the efficiency of partial lateral facetectomy of the patella in achieving proper tracking of the patella was evaluated in 116 patients who underwent unresurfaced patellar-retaining TKA. The radiographic outcome measures included the patellar tilt and patellar shift. The functional outcome was assessed with Kujala anterior knee pain scale.
Results: The Mean±SD age of the patients was 66.3±7.6 years. The mean follow-up of patients was 20.6±8.9 months. The Mean±SD patellar tilt was 10.5±7.2° before the surgery and 4.4±5° after the operation (P<0.001). The Mean±SD preoperative patellar shift was 3.3±4.3 mm which improved to -0.2±2.8° after the surgery (P<0.001). The Mean±SD Kujala score of the patients was 74.6±7.1, ranging from 54 to 89. No complication was recorded during the follow-up period.
Conclusion: Partial lateral facetectomy of the patella provides an acceptable radiographic and functional outcome in patients undergoing primary TKA. Therefore, it could be regarded as a valuable alternative to lateral release in unresurfaced patellar-retaining TKA.

Abstract
Rupture of the extensor mechanism of knee joints is rare in patients without any systemic disease. Many reports have described tendons getting ruptured at various sites of the extensor mechanism. We report a case of patellar tendon avulsion from the tibial tuberosity on the right side and quadriceps tendon avulsion from the patella on the left side sustained in one accident. A 54 years old man presented with the above non-identical bilateral extensor mechanism rupture who had no pre-existing systematic diseases and was not on any steroid treatment. Tendon ruptures were always related to systemic degenerative/inflammatory conditions or usage of steroids. However, the reason for the rupture of different parts of the extensor mechanism after minor trauma in case of tendinopathy or after a significant trauma in a normal patient is not well explained. We believe that the degree of knee flexion at the time of injury plays an important role in the site of rupture of the extensor mechanism.
