Patellar fracture and avulsion of the patellar ligament complicating arthroscopic anterior cruciate ligament reconstruction.

Abstract: Arthroscopic reconstruction of the anterior cruciate ligament-deficient knee using the middle third of the patellar tendon is an effective treatment for acute or chronic anterior cruciate ligament insufficiency. The strength of this bone-ligament-bone graft is superior to virtually all other autogenous tissue utilized. We report the complication of avulsion of one half of the remaining patellar tendon from the tibia associated with patellar fracture in the early postoperative period.

Results of total knee arthroplasty using the posterior stabilized condylar prosthesis. A report of 137 consecutive cases.

Abstract: One hundred thirty-seven consecutive posterior stabilized total knee arthroplasties (TKAs) were reviewed Average age of the patient was 611 years and length of postoperative follow-up period was 292 months Patients were evaluated using the Hospital for Special Surgery (HSS) knee rating scores Average preoperative scores improved from 52 to 92, postoperatively Ninety-eight percent of patients had no pain or mild occasional pain postoperatively compared with 99% of patients experiencing severe to disabling pain preoperatively Complications included one myocardial infarction, two deep venous thrombosis, one urinary tract infection, one patellar dislocation, and four wound problems There were two incidences of seroma, one hematoma, and one deep infection requiring revision after joint debridement and systemic antibiotics Also noted was one incidence of ligamentous laxity and one patella fracture

A new technique of harvesting patellar tendon autografts for anterior cruciate ligament reconstruction

Abstract: A new surgical technique to uniformly harvest the middle one-third of the patellar tendon for anterior cruciate ligament reconstruction is described. The technique uses a guide system of 8 templates of varying widths to guide the saw cuts and "collared," depth-controlled saw blades and drill bits to produce a standard cutting and drilling depth. This kind of template system lessens the risks of graft harvesting complications such as patella fracture, bone graft fragmentation, suture pull out, and judgment errors pertaining to graft depth, length, or width. The Patellar Tendon Graft Guide was used to obtain a patellar tendon graft in 65 patients. Fifty-nine arthroscopic-assisted and 6 open anterior cruciate ligament reconstructions were performed. Of the 65 grafts harvested, 63 consistently demonstrated bone portions 20 mm in length, 7 mm in depth, and a width corresponding to the template chosen (usually 10 mm). Two grafts supposed to be 10 mm in width turned out to be 9 mm in width because of a technique related problem.

The operative repair of displaced patellar fractures.

Abstract: Open reduction and internal fixation was used to treat 17 patients with displaced patellar fractures. The fractures were classified as transverse in five patients, transverse with comminuted distal pole in nine, and comminuted in three. The type of the fracture sustained was consistent with the mechanism of injury (eg, a fall, dashboard injury, motorcycle or pedestrian accident). Follow-up averaged 4 years (minimum, 1 year) including clinical and roentgenographic evaluation. Results in 11 patients were categorized as excellent, four as good, and two as unsatisfactory. The primary fixation method was modified tension band, which worked well in transverse fractures and in patients with minimal comminution. When the patella was comminuted, partial excision of the small fragments and internal fixation provided better results than fixation of all the fragments. The roentgenographic analysis did not always correlate with the clinical result. Two patients sustained a medial femoral condylar injury with their patellar fracture and had complicated treatment courses. These concurrent injuries may be predictive of a poor result.

Patella Fracture: Review of the Literature and Five Case Presentations

Abstract: Patella fractures comprise one percent of all fractures treated in the hospital. They are classified as: 1) transverse, 2) pole, 3) comminuted, and 4) vertical or longitudinal. The principal cause of such fractures is the direct force involved in a fall, an industrial accident, or a motor vehicle accident. Patients who have experienced such fractures are mostly middle-aged and actively employed. In 50 to 66 percent of the cases, surgical treatment is not required. Physical therapy treatment for patella fractures in the medical literature is reviewed. Case studies of five patients ranging in age from 57 to 71 are presented. In these cases the fracture was due to a fall. Two of the five patients had been treated surgically. At the time of discharge from physical therapy, there were persisting problems. These included: knee pain, difficulty with stair climbing, need for assistive devices on uneven surfaces, and weakness of quadriceps and/or hamstrings muscles.

Adjustable restitution device for fracture of patella

Abstract: The utility model relates to an adjustable reposition device for patella fracture, which comprises a left claw lobe 1, a right claw lobe 3 and screws 2. The utility model is characterized in that the rectangular plane of the upper part of the left claw lobe is provided with a tooth-shaped groove 7; the tooth-shaped groove 7 on the right claw lobe 3 are clamped in the tooth-shaped groove 7 of the left claw lobe 1 and are fastened by the screws 2. The utility model has the advantages of simple structure and convenient operation and is divided into two lobes, so that the firm and reliable fixation can be ensured and the surgical operation can be accomplished at a time; the during time of the surgical operation being shortened, without external plaster fixation after the surgical operation, the patient can do out-of-bed activities early.

Treatment of the Patellar Fractures

Abstract: We reported end-results of 19 cases (13 males and 6 females) with patellar fracture, who entered our clinic. These cases were 17 to 78 years old, and followed for 1 years and 8 months to 7 years and 10 months (mean, 4 years and 6 months). They were evaluated for the range of motion of the knee joint, Pain, limping, muscle atrophy of quadriceps and grade of satisfaction. The clinical results were excellent in 11 cases, good in 5, fair in 3 and poor in none. Their main complaint was fatigue of knee, and those patients had muscle atrophy of quadriceps. Comminuted fracture and the step-off of articular surface after treatment contributed to poor results.
