These devices combined rigid fixation devices (e.g., interosseous K‐wire) and tensile fixation devices (e.g., figure‐8 wire).…”
Purpose
This study aimed to comprehensively review the existing evidence concerning surgical treatment of inferior pole fractures of the patella and to report the outcomes and complications of different fixation techniques.
Method
This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches of PubMed, Scopus, and Web of Science were conducted in March 2023. Studies were screened against predecided inclusion and exclusion criteria. The extracted data included fracture characteristics, surgical techniques, and radiographic and functional outcomes. The Methodological Index for Non-Randomized Studies (MINORS) quality assessment tool was used to assess the eligible literature. The primary outcome was postoperative range of motion of different surgical methods, and the secondary outcomes were other clinical results and complications.
Results
A total of 42 studies satisfied all the inclusion criteria and were deemed suitable for review. Fourteen case–control studies and 28 case series were selected, for a total of 1382 patients with a mean age of 51.0 years (range = 11–90). The follow-up period ranged from 6 to 300 months. The surgical techniques were categorized based on the device used as follows: (1) rigid fixation device; (2) tensile fixation device; (3) mixed device; and (4) extra-patella device.
Conclusion
Regarding the outcomes following surgical treatment of inferior pole fractures of the patella, the postoperative range of motion (ROM) of each technique ranged from 120° to 135°, with the exception of that involving the patellotibial wire which had poorer outcomes. The lowest functional score was also found in those using the patellotibial wire. Complications after surgery are rare, but approximately half of the patients required additional surgery for implant removal, particularly those whose initial surgery involved rigid fixation devices. It's worth noting that bony fragment excision is no longer recommended, and the combined use of multiple surgical devices is now more common.

“…Post-operative patella baja is reported in 12–57% of patella fractures [ 12 - 15 ]. Park et al noted that even though significant patella baja was caused by patellar tendon shortening after tightening the patellar tendon using a SA, there were no postoperative complications related to patella baja, such as patellofemoral pain, instability, or extension limitation of the knee joint [ 16 ].…”
Introduction: Patella fracture can occur due to direct injury to the knee or indirect eccentric contraction of the quadriceps tendon. These injuries can present in different configurations which require acceptable reduction and good fixation. Patients are at risk of not only losing their knee extensor mechanism but also having a defective patellofemoral articulation. Hence, the main aim in treating such fractures is to restore the knee extensor mechanism. Surgical options for treating patella fracture include tension band wiring, wiring through cannulated screws, fixation with plate, and suture anchor (SA) fixation. Case Report: We demonstrate a new fixation technique for patella fracture with SAs in two of our patients. They presented with patella fracture following a fall and sustained closed injury with intact distal neurovascular status. The authors describe their technique using double-loaded SAs to obtain anatomical reduction and solid fixation. With three SAs, each inserted in a third portion of a distal fragment. Conclusion: There are several modalities and techniques available for fixation of patella fracture. However, authors recommend that their described novel technique can provide more strength and satisfactory outcome. Furthermore, this technique uses a smaller incision compared to conventional suture tunnel repair as in this technique only the fracture that needs to be exposed distally.
