Clinical outcomes after absorbable suture fixation of patellar osteochondral fracture following patellar dislocation

Abstract: Background: Osteochondral fracture (OCF) is one of the severe complications following a patellar dislocation. The appropriate fixation method for patients with OCF remains controversial. Methods: Eighteen patients who had undergone surgery after a patellar dislocation were recruited retrospectively. Patellar OCF was fixed with an absorbable suture in an unreported method. The medial patellofemoral ligament (MPFL) was repaired or reconstructed if necessary. The Lysholm and Kujala knee scoring systems were used … Show more

“…23,25 If the fracture is treated surgically, the primary procedure is reduction and fixation of the OCF fragment into its original location using biodegradable pins or sutures. 8,10,28,29 If refixation is not possible, microfractures, subchondral drilling, or periosteal or abrasion chondroplasty may be considered. 9,24 Despite the theoretical basis of the biomechanics of injury mechanism, literature describing the anatomic characteristics of OCFs in the knee joint after patellar dislocation is limited.…”

“…However, this article differs from the present study in that it includes recurrent dislocators as well as adults. No redislocations were observed and good clinical outcomes were presented [18]. Pritsch et al described six cases of transpatellar suture OCF fixation with no complications in a twoyear follow-up; however, neither functional scores nor MRI were used [19].…”

“…Many different methods of fixation are described in the literature, including suture, bioabsorbable pins, and Herbert screw; transpatellar PDS suture proved to be effective and inexpensive in osteochondral fractures greater than 1 cm 2 within the weight-bearing area [11,18,19]. e suture method is suitable for young patients and is not associated with the risk of implant penetration to the joint and secondary need of its removal [6,11].…”

“…Classically, the treatment of OCFs include osteosynthesis of the fragment with different devices described in the literature, such as standard compression screws, headless compression screws, Herbert screws, bioabsorbable screws and pins, meniscus arrows, or sutures passed through complete bone tunnels. [6][7][8][9][10][11][12][13][14][15][16][17][18] Occasionally, when the subchondral bone or the fragment is too small for fixation or chronic, it has to be removed and managed with cartilage restorative techniques, such as debridement and/or micro/nanofractures, autologous chondrocyte implantation/ matrix-induced chondrocyte implantation, mosaicplasty, bone grafts and scaffolds, biomaterials or fresh osteochondral allograft, depending on the size and depth of injury. [19][20][21][22][23] The purpose of this Technical Note is to describe the one-stage osteochondral fracture repair technique with knotless anchors and interconnected crossing suture sliding loops, with no complete bone tunnels, no need for a second-stage surgery hardware removal, and suitable in certain cases (Table 1) and for different anatomic locations, such as patella, condyle, or trochlea defects.…”
