Background: Several fixation methods have been introduced in medial patellofemoral ligament (MPFL) reconstruction. However, the optimal management of patients with recurrent patellar dislocation remains controversial. Purpose: To present a case series with a minimum 2-year follow-up of 29 patients with recurrent patellar dislocation who underwent a new transosseous suture fixation technique for MPFL reconstruction. Study Design: Case series; Level of evidence, 4. Methods: From January 2014 through February 2016, a total of 29 patients with recurrent patellar dislocation for which the MPFL was reconstructed with transosseous suture patellar fixation were studied. All patients were available for follow-up (mean, 37.52 months; range, 26-48 months). The patellar attachment was fixed by transosseous patellar sutures. The International Knee Documentation Committee (IKDC) subjective knee score, Kujala score, Tegner score, range of motion, congruence angle, patellar tilt angle, and complications were assessed both pre- and postoperatively. Results: No recurrent dislocation was observed in any of the 29 patients for a minimum of 2 years. All outcome scores improved significantly from preoperatively to postoperatively: the average IKDC subjective knee evaluation score from 53 to 87, Kujala from 54 to 90, Lysholm from 50 to 89, and Tegner from 3 to 5 ( P < .001 for all). The congruence angle significantly decreased from 22° preoperatively to –3° postoperatively, and the patellar tilt angle (Merchant) decreased from 23° preoperatively to 5° postoperatively ( P < .001 for both). In total, 25 patients (25/29; 86.21%) were completely pain-free when performing activities of daily living at the last follow-up, and 27 patients (93.1%) rated themselves as very satisfied or satisfied with the results. Conclusion: In patients with chronic recurrent patellar dislocation, transosseous patellar suture fixation for MPFL reconstruction can significantly improve patellar stability and achieve good results at short-term follow-up.

Aim. The aim of the study was to analyze the clinical results and MRI scans after transpatellar osteochondral fracture fixation following patellar dislocation. Methods. Our study group comprised 17 patients with patellar dislocation followed by osteochondral fracture of the articular surface of the patella. All patients underwent surgery where the fractured osteochondral fragments of the patella were attached using the transpatellar suture technique. The mean age at the time of surgery was 14.1 years, and the mean follow-up period was 7.5 years. Results. The results of the patellar compression test and the apprehension test were negative in all patients. The mean Lysholm and Kujala scores were 89.2 and 89.6, respectively. The MRI scan revealed healing of the fixed fragment and restoration of the articular surface in all patients. In 16 cases, subchondral bone of the fixed fragment area was described as irregular: its articular cartilage was narrowed and not homogenous. Progressive degenerative changes were observed in the patellofemoral joint at follow-up in three patients. Conclusions. By fixing osteochondral fragments, the patellar articular surface can be restored. The MRI scans show that the cartilage in the reconstructed surface is narrowed after a mean 7.5-year follow-up.

Introduction: Dislocation of patella is a very common injury which usually reduces spontaneously or can be reduced easily using gentle manipulation. Irreducible patellar dislocations are rare and usually result due to either rotation of patella along the horizontal or vertical axis or due to bony impaction. Neglected locked patellar dislocations are extremely rare injuries presenting additional challenges. Case Report: We are reporting a case of a 24-year female who presented to us 4 months after suffering a knee injury for which she received native treatment initially. On presentation, patient was able to walk with a limp and some discomfort but was unable to squat or sit cross-legged. Clinical examination revealed a patellar dislocation which was irreducible. On open reduction, the patella was found to be locked in the lateral gutter with rotation along its vertical axis and with an osteochondral fracture of its medial margin. There were a lot of fibrotic adhesions which required extensive release, following which the patella could be derotated and reduced into the trochlear groove. The medial retinaculum was repaired using transosseous sutures. Postoperatively, the patient developed wound edge necrosis which was managed with debridement and secondary suturing. At 1-year follow-up patient had almost full knee range of motion without any signs of patellar pain or instability and was able to squat and sit cross-legged. Conclusion: Unlike acute irreducible patellar dislocations which can be managed easily with open reduction, a neglected dislocation necessitates wider surgical exposure and a lot of soft tissue releases, which may jeopardize vascularity of the soft tissues leading to wound healing problems. Release of all adhesions while taking care to prevent further chondral injury, adequate lateral retinacular release, derotation of patella to relocate it into trochlear groove, and meticulous medial retinacular repair is essential for a successful outcome.

Abstract Background The purpose of this study was to evaluate the clinical and radiographic outcomes after medial patellofemoral ligament (MPFL) reconstruction combined with supracondylar biplanar femoral derotation osteotomy (FDO) in recurrent patellar dislocation (RPD) with increased femoral anteversion angle (FAA) and genu valgum. Methods Between January 2017 to December 2020, a total of 13 consecutive patients (13 knees, 4 males and 9 females, mean age 18.7 (range, 15–29 years) with RPD with increased FAA (FAA > 25°) and genu valgum (mechanical axis deformity of ≥5°) who underwent supracondylar biplanar FDO using a Tomofix-locking plate combined with MPFL reconstruction in our institution were included. Preoperative full-leg standing radiographs, lateral views, and hip-knee-ankle computed tomography (CT) scans were used to evaluate the mechanical lateral distal femoral angle (mLDFA), anatomical femorotibial angle (aFTA), mechanical axis, patellar height, tibial tubercle-trochlear groove (TT-TG) distance, and torsional angle of the tibial and femoral in the axial plane. Patient reported outcomes were evaluated using the International Knee Documentation Committee (IKDC) score, Kujala score, Lysholm score, visual analog scale (VAS), and Tegner score preoperatively and postoperatively. Postoperative CT scans were used to evaluate the changes of FAA and TT-TG, and full-leg standing radiographs was used to evaluate the changes of mLDFA, aFTA, and mechanical axis. Results A total of 13 patients (13 knees) were included with an average follow-up period of 26.7 months (range 24–33). No cases developed wound infection, soft tissue irritation, and recurrent patellar dislocation during the follow-up period after surgery. Bone healing at the osteotomy site was achieved in all cases, and all patients regained full extension and flexion. Clinical outcomes (VAS, Kujala, IKDC, Lysholom, and Tegner scores) improved significantly at the final follow-up after surgery (p < 0.05). The mean mLDFA, aFTA, mechanical axis, and TT-TG distance showed statistically significant improvement following the combined surgery (p < 0.05), while the CDI did not change significantly after surgery (p>0.05). Conclusion MPFL reconstruction combined with supracondylar biplanar FDO showed satisfactory clinical outcomes and radiographic results in the short-term follow-up period.
