“…No evidence of posttraumatic arthritis or progression of preexisting degenerative patellofemoral joint osteoarthritis was observed. At the final follow-up, Böstman knee scores were excellent in 88 cases (28)(29)(30), good in 55 (20)(21)(22)(23)(24)(25)(26)(27), and unsatisfactory in 13 (<20). According to SF-36 evaluation, the average score was 84.5 (range, 62-91).…”

Operative treatment is usually recommended in displaced patella fractures. Several techniques have been advocated for internal fixation of patella fractures. Despite the relatively good clinical outcomes that have been demonstrated in many studies, postoperative morbidities such as fixation failure, nonunion, infection, and knee stiffness are not uncommon. We present a new alternative treatment technique for displaced patellar fractures. Between April 1995 and May 2005, we used the Nitinol Patella Concentrator (NTPC) to treat 156 consecutive patients with displaced patellar fractures. Injuries arose from vehicular accidents in 56 (35.9%) cases, direct falls onto the knee in 85 (54.5%) cases, and sports injuries in 15 (9.6%) cases. The mean patient age was 46.3 years (range, 25-77 years). Clinical assessments were made using the Böstman knee score and the MOS SF-36 questionnaire (Medical Outcomes Study 36-item short-form health survey), which were both recorded at the final follow-up visit. The mean follow-up was 7.3 years (range, 6-17 years). At the final follow-up, the Böstman knee scores were excellent in 88 cases (28-30), good in 55 (20-27), and unsatisfactory in 13 (<20). According to the MOS SF-36 evaluation, the average score was 84.5 (range, 62-91). Treatment of patellar fracture with the NTPC not only may serve as an effective and rigid fixation method in multifragmented displaced and inferior pole fractures, but also may provide continuous concentrative compression during the osseous healing process. Thus, use of the NTPC may help restore the functional integrity of the extensor mechanism and permit early rehabilitation with a lower incidence of postoperative complications.

“…The basket plate technique has been described in two clinical reports. 26,27 The plate conforms to the shape of the inferior patellar pole and is secured to the patellar body with superiorly directed screws. Fixed-angle plate osteosynthesis had been described since 2010, as an alternative to tension wiring.…”

ObjectiveModified anterior tension wiring with K-wires and cannulated lag screws with anterior tension wiring are currently the fixation of choice for patellar fractures. Failure of fixation, migration of the wires, postoperative pain and resulting revision surgery, however, are not uncommon. After preliminary biomechanical testing of a new fixed-angle plate system especially designed for fixation of patella fractures the aim of this study was to evaluate the surgical and anatomical feasibility of implanting such a plate-device at the human patella.MethodsIn six fresh unfixed female cadavers without history of previous fractures around the knee (average age 88.8 years) a bilateral fixed-angle plate fixation of the patella was carried out after previous placement of a transverse central osteotomy. Operative time, intra-operative problems, degree of retropatellar arthritis (following Outerbridge), quality of reduction and existence of any intraarticular screw placement have been raised. In addition, lateral and anteroposterior radiographs of all specimens were made.ResultsDue to the high average age of 88.8 years no patella showed an unimpaired retropatellar articular surface and all were severely osteoporotic, which made a secure fixation of the reduction forceps during surgery difficult. The operation time averaged 49 minutes (range: 36-65). Although in postoperative X-rays the fracture gap between the fragments was still visible, the analysis of the retropatellar surface showed no residual articular step or dehiscence > 0.5 mm. Also in a total of 24 inserted screws not one intraarticular malposition was found. No intraoperative complications were noticed.ConclusionsOsteosynthesis of a medial third patella fracture with a bilateral fixed-angle plate-device is surgically and anatomically feasible without difficulties. Further studies have to depict whether the bilateral fixed-angle plate-osteosynthesis of the patella displays advantages over the established operative procedures.

“…[12,13] To avoid intrinsic shortcomings of tension wiring, some new internal fixations have been designed and applied in clinical trials such as a fixed angle plate, a locking patella plate and TNSMPC in our study. [17][18][19] The TNSMPC applied in our study was designed according to the anatomic characteristics of patellar and was made of Ti-Ni alloy with high excellent corrosion resistance and desired histocompatibility.…”

Purpose The purpose of this study was to investigate the efficiency of Ti-Ni shape-memory patella concentrator(TNSMPC) combined with cannulated compression screws in the treatment of comminuted patella fracture. Methods Between January 2014 and January 2017, 54 patients of C2 and C3 patella fractures underwent open reduction and internal fixation with TNSMPC combined with cannulated compression screws. All the patients got standard postoperative rehabilitation programs and were regularly followed up for at least 12 months after the operation. X-rays, knee functions and life quality were evaluated during the follow-up. Results All the patients achieved bone healing and recovery of knee function with low incidence of complications according to X-rays and questionnaire surveys. The average operation time and blood loss during surgery were 77.5±25.12minutes and 24.25±4.70ml respectively. The Knee Outcome Survey Activities of Daily Living Scale, range of motion, 36-item Short-form heath survey after the operation were all improved. According to the Bostman’s criteria, the excellent to good rate was 92.6%. Conclusion TNSMPC combined with cannulated compression screws is an effective fixation for C2 and C3 patella fracture with excellent clinical outcomes. In addition, the operation does not increase extra technique difficult or tissue damage relatively, which is worth promotion.
