Chronic Patellar Tendon Rupture Reconstructed with Hamstring Graft – A Case Report

Neglected patella tendon rupture which are presented 6 weeks after injury are rare but it can be disabling. Aim of study is to determine the outcomes of chronic patellar tendon rupture reconstructed using hamstring graft. This case report concerns a 26 year-old man who came with complaints of weakness of legs, difficulty in climbing stairs up and down, difficulty in getting up from squatting position. X-ray of Right knee showed high riding patella. MRI showed full thickness rupture of ACL. The patient was operated with a combination of Chen et al and ganga hospital SR Sundararajan7. Our outcome was also excellent with no extensor lag, Kujala score was 94.1, Lysholm score was 92.3. From our study it is found that even in chronic neglected cases of patellar tendon rupture, good functional results can be obtained by repair using hamstring graft.

Bilateral patella tendon rupture in young female on oral steroid: A case report

Rupture of bilateral patella tendon has been discussed in case reports. We present a case of young female with bilateral patella tendon rupture with a history of oral steroid intake for 10 weeks before injury. She was able to join office job 6 months after surgical repair and intensive rehabilitation. Despite unclear pathophysiology, the use of steroids has been associated with tendon injuries.

Superior Dislocation of Patella Without Osteophytes – A Rare Case

A 66-year-old woman sustained a “sprain” of her right knee while walking inside a supermarket. She complained of sudden knee pain and was unable to walk or move her right knee. She attended Accident and Emergency Department and was admitted into Orthopaedic ward with a diagnosis of “patella tendon rupture”. Physical examination on admission showed swelling, bruise and local tenderness just below the inferior pole of upward migrated patella bone. The extensor mechanism was loss. Passive knee motion was 0-20 degree only, limited by pain. Plain radiographs showed superior migrated patella. Beside ultrasound showed intact patella tendon. Closed reduction without anaesthesia was done successfully with an immediate regain of knee motion to 0-80 degree. Post-reduction x ray showed reduced patella with no fracture. Follow-up at 6 weeks showed normal active motion knee motion with full quadriceps power. Superior patellar dislocation is a rare condition. At 2016, only 23 cases were reported in English literature. It should be considered as a differential diagnosis of patella tendon rupture or locked knee. Pathognomonic radiographic features include proximal displaced patella with superior pole tilted away from femur and a dimple in skin. Ultrasonography may be used to exclude patella tendon rupture, which is a more common diagnosis in elderly. Most superior dislocations are due to interlocking patella and trochlear osteophyte. This may the second reported case of superior dislocation of patella without osteophytes. Closed reduction may be done without general anaesthesia. After reduction of superior patella dislocation, the functional recovery is rapid.
