When the five patients with the large OCFs involving the central ridge were included in the outcome analysis of redislocation rate (all of the five patients were regarded as redislocation cases of group 1), the intergroup difference of redislocation rate was also insignificant (p = 0.108). The only difference is that with an osteochondral fracture, there may also be a bone fracture involved. converted Others were allocated into group 2 (45 cases). Clin J Sport Med. Patellar fractures are infrequent, with an incidence of approximately 1.2 per 100,000 per year [1]. Acute dislocation of the patella with osteochondral fracture: a review of eighteen cases. Acute dislocation of the patella: results of conservative treatment. Thus, initial surgery should be considered for such cases. Correspondence to 1996;24(1):52–60. Various other authors have reported a 10 to 30% incidence of intra-articular osteochondral injuries seen on radiographs after APD [17, 26,27,28,29,30]. The study was approved by IRB (institutional review board)/EC (Ethics committee) of our hospital (approval number: HDT 2019–06-016).

Based on multiple studies demonstrating similar functional outcomes after both conservative and operative procedures for treatment of APD, Conservative treatment has been traditionally the preferred option for APD without an osteochondral fracture (OCF) [1,2,3,4,5,6,7,8]. Text 1997;68(5):419–23. In the present study, locations of defects were patellar medial margin, patellar inferomedial facet, and inferomedial facet involving central ridge. 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. endobj internal Eur J Orthop Surg Traumatol. In majority of the studies, patellar osteochondral fracture is associated with a bony contusion involving the lateral femoral condyle in the classical impaction pattern of injury . Operative versus closed treatment of primary dislocation of the patella. Acta Orthop Scand. In the present study, APD with OCF occurred in 35% of total subjects, similar to recent studies. However, if the fragment is big enough, many other treatment choices are available to fix osteochondral fractures of the patella, including replacement of the native fragment with internal fixation, resorbable implant fixation, crossing suture technique, allograft replacement, autograft replacement, and autologous chondrocyte transplantation [2, 11–21]. Text J Bone Joint Surg Am. Redislocation rate was 31.2% in group 1 and 26.6% in group 2, showing no significant difference between the two groups (p = 0.690). b Osteochondral fragment next to LFC (arrow). All patients were treated with a supervised course of immobilization followed by progressive range of motion and strength exercise protocol. Surgical options range from simple fragment excision to internal fixation of the fracture fragment to more complex cartilage restoration or replacement procedures. If further exposure of the articular surface of the patella is needed to repair osteochondral fragments, a vertical incision extending from the traumatic tear in the lateral retinaculum may enable the patella to be everted 90 degrees.6 Alternatively, Berg7 described the use of tibial tubercle osteotomy to expose comminuted patella fractures. Acute patellar dislocation,Medial patellar fracture,Osteochondral fracture,Redislocation J Bone Joint Surg Br Vol. Our study group comprised 17 patients with patellar dislocation followed by osteochondral fracture of the articular surface of the patella. 2008;90(3):463–70.

This small sample size was inevitable because of delicate inclusion criteria. Second, the follow-up period was relatively short. Although wearing a brace or cast may ease the discomfort of an osteochondral lesion, they are usually not enough to remedy the problem permanently, except in children, who can respond well to non-surgical treatment. 1986;14(2):117–20. Wheareas, as the dislocated patella is reduced from a lateral to a medial direction by the pull of vastus medialis, the medial facet of the patella can impact the lateral femoral condyle which may result in fracture, leaving the fracture fragment in the lateral gutter [16]. Text Trapped internal Sillanpaa PJ, Salonen E, Pihlajamaki H, Maenpaa HM. All patients were recommended to perform protective weight bearing for 4 weeks with knee brace and crutches. First, APD patients with OCFs of medial margin or inferomedial facet showed similar redislocation rates and functional knee scores with those without OCF after supervised conservative treatment. sn Thus, 69 patients including 42 males and 27 females met inclusion criteria. URI stFnt converted to PDF/A-2b internal Based on above-mentioned studies reporting similar clinical outcomes and redislocation rate after APD with OCF between surgical and non-surgical treatment, these findings motivated us to hypothesize that conservative treatment could be reasonable treatment option for treating APD with OCF.
