Absence of patella may be caused by congenital factors, trauma and surgical operations (patellectomy, etc). Complete absence of bilateral patellae is rare in clinical case. We report a case of posttraumatic bilateral patella excision. To the best of our knowledge, absence of bilateral patellae caused by self-mutilation has never been reported. Our patient and his family members were informed that the data concerning this case would be submitted for publication.

There is a dearth of case reports describing simultaneous bilateral patellar tendon ruptures in the medical literature. These ruptures are often associated with systemic disorders such as lupus erythematosus or chronic steroid use. The author describes a case of a 24-year-old man who sustained traumatic bilateral patellar tendon ruptures without any history of systemic disease or steroidal medication. We repaired and reattached the ruptured tendons to the patella and augmented our procedure with allogeneic tendon followed by wire loop reinforcement. One year after operation, the patient regained a satisfactory range of motion of both knees with good quadriceps strength and no extensor lag. The recurrent microtrauma from a history of intense sports activity and a high body mass index may have played an important role in this trauma event.

OBJECTIVETo evaluate clinical effect of micro-modified Fulkerson osteotomy under arthroscope in treating habituation patellar dislocation.

METHODSTwenty patients of habituation patellar dislocation (25 knees) were treated by the medial retinaculum plication, lateral retinaculum releasing and modified Fulkerson osteotomy (tibial tubercle anteromedial transfer) under arthroscope. There were 5 males and 15 females with the age from 16- to 28-years-old (average of 21 years). The subjective symptoms and the joint function were evaluated according to Lysholm and Tegner scoring system.

RESULTSAll the patients were followed up from 12 to 36 months with an average of 24 months. No found redislocation in the patients. The Lysholm score was 54.4 +/- 12.1 and 87.7 +/- 9.6 (t=2.33, P<0.05) before and after surgery respectively. The Tegner score was 2.8 +/- 0.8 and 5.1 +/- 1.3 (t=4.36, P<0.01) before and after surgery respectively.

CONCLUSIONMicro-modified Fulkerson osteotomy under arthroscope for the treatment of habituation patellar dislocation is a rescheduled in extend knee equipment, its advantages including affirmative effect, minor damage, quick rehabilitation, fewer complications and lower rate of recurrence after operation.

OBJECTIVETo investigate the effects of different treatments for different patella fractures, and analyze the clinical outcome.

METHODSOne hundred and sixty-four patients with patella fracture were treated between July 2005 and December 2009, 113 males and 51 females with an average age of 38.5 years old, ranging from 21 to 72 years. There were 21 cases of linear fracture or separation of the patella < 0.5 cm, 63 of patella separation > 0.5 cm and for the pure horizontal type or vertical-type fractures, 34 cases were separated into three block, 46 cases were separated into four and above. Of 164 cases, 21 patients accepted traditional treatment, 39 patients were fixed with cerclage wire and tension band wire, 43 with cannulated screws and tension band wire fixation, 29 with cannulated screws for the minimally invasive treatment, 32 patients with fixation of NT-PC RESULTS: One hundred and sixty-four cases were followed up with a mean period of 14 months (3 to 36 months). By Lysholm knee score criteria: 19 cases in traditional treatment were excellent and good, 36 cases in cerclage wire and tension band wire technique cases were excellent and good, 40 cases in cannulated screws and tension band wire fixation, 27 cases in cannulated screws for the minimally invasive treatment were excellent and good, 30 cases in NT-PC were excellent and good.

CONCLUSIONThe surgery should be avoided if the patients can be treated with manipulation and fixation. Those who need surgical treatment should be based on the type of fracture to select a different surgical operation. Percutaneous reduction can be fixed, and try to minimally invasive surgery. Whether traditional treatment or internal fixation, the appropriate functional exercise need to make as early as possible.

Transverse fracture is the most common in patella fracture and tension band fixation is one of the most effective methods. Surgical wire tension band technique is simple, the use of materials is also simple, but it is not strong and difficult to promote. Kirschner tension band technique can get satisfactory reduction with reliable fixation, but it is easy to complicate with steel wire breakage and Kirschner loosening. Screw tension band technique inherits the traditional advantages of simple manipulation and reliable fixation, also overcomes the disadvantages of early activity limitations caused soft tissue irritation of tension band around knee, the slippage and breakage of internal fixation, and the technique can be popularized generally.

OBJECTIVETo investigate the clinical effects of double-loop cerclage wire No. 10 and the two-part patellar concertration for treatment of comminuted patellar fracture.

METHODSFrom June 2004 to June 2011, 86 patients with comminuted patellar fracture were treated with double-loop cerclage wire No. 10 and the two-part patellar concertration. They included 48 males and 38 females ranging in age from 19 to 75 (mean 42.5) years. Fifty-two cases were affected in the left and 34 cases in the right, with 3 fracture pieces in 32 cases, 4 fracture pieces in 25 cases and more than 4 fracture pieces in 29 cases. The operation time was 40-70 minutes. The therapeutic effects were evaluated by Bostman patella fractures criteria in all patients.

RESULTSAll patients were followed-up for 3 months to 6 years (mean 3.5 years). The overall Bdstman score was (27.65 +/- 2.05). The outcome was excellent in 78 cases and good in 8 cases.

CONCLUSIONThe double-loop cerclage wire No. 10 and the two-part patellar concertration for comminuted patellar fracture is advantageous due to simplicity, good reduction, stable fixation,early functional exercise, and satisfactory functional recovery.

OBJECTIVETo study therapeutic effects of patella and femur fixation combined with percutaneous suture in the treatment of patellar fractures.

METHODSIn the study,23 patients with patellar fractures were treated with percutaneous Kirschner-pin transfixation and percutaneous suture after Kirschner pins transfixation of superior pole of patellar and condyle of femur. Among the patients, 17 patients were male and 6 patients were female, ranging in age from 18 to 73 years (mean 32.4 years). The therapeutic effects were evaluated according to Bistman criterion for patellar fracture.

RESULTSAll the patients were followed up and ranged from 6 to 38 months (mean 11 months). All the fractures were anatomically reduction or near-anatomical reduction. According to Böstman criterion for patellar fracture, 20 were excellent and 3 good.

CONCLUSIONThe method of patella and femur fixation combined with suture for patellar fractures has such advantages as smaller invasion, less complication or sequel, fine reduction of fracture, good restoration of joint function and none operative cicatrix.
