Patellofemoral problems are considered to be among the most frequent causes of knee pain in children and adolescents. Correcting bone abnormalities through specific and targeted interventions is mandatory in skeletally immature patients. Medial patellofemoral ligament (MPFL) reconstruction is the preferred procedure, but there are several important precautionary considerations that the surgeon must take into account. it must always be remembered that MPFL rupture is the result, not the cause, of an altered extensor mechanism; therefore, patellar stabilization with MPFL reconstruction is only the first step to be accomplished in the management of an MPFL rupture. If other anatomical alterations are encountered, alternative/additional surgical procedures should be considered. If MPFL rupture occurs without associated anatomical or functional knee alterations, an ap propriate rehabilitation program after MPFL reconstruction should be sufficient to achieve a good outcome.In conclusion, an acute patellar dislocation should be managed conservatively unless there is evidence of osteochondral damage or medial retinaculum lesions. Osseous procedures are contraindicated in children, while MPFL anatomical reconstruction with “physeal sparing” is the primary surgical option.

<p>Patellofemoral instability is a painful and often recurring disorder with many negative long-term consequences. Surgical treatment for patellar dislocation has evolved from the initial medial reefing to the present-day anatomical reconstruction of medial patellofemoral ligament (MPFL) which is thought to be the most appropriate treatment. MPFL reconstruction successfully addresses patellofemoral instability by restoring the deficient most important static primary soft tissue restraint. This prospective case series was conducted at a Tertiary care Govt. Hospital in Kolkata between January 2019 to August 2020 on 15 patients who underwent MPFL reconstruction for recurrent patellar dislocation. All patients were followed up at an interval of 2 weeks, 6 weeks, 3 months and 6 months. Kujala score was used to assess the functional outcomes of the patients. Out of 15 patients, 13 (86.7%) showed good to excellent results whereas 2 (13.3%) had Fair outcome and none of the patients demonstrated Poor surgical result. The mean Kujala score improved from 49.6 pre-operatively to 92.7 post-operatively. By the end of 6 months follow-up, 13 (86.7%) patients achieved almost full range of motion. Majority (80%) of patients did not have any complications. Only 2 patients had a post-operative recurrence (13.3%). Reconstruction of MPFL using autologous hamstring graft showed excellent results over the short term with a low re-dislocation rate and acceptable complication rates. It greatly helps in preventing further episodes of patellar subluxations or dislocations and in improving quality of life.</p>

Study Participants

Objectives: To evaluate the clinical outcome after medial patellofemoral ligament (MPFL) reconstruction for patellofemoral instability in skeletally immature patients. Methods: Study participants were 8 patients ( median age, 10 years; range, 5-14 and one male , others female) who had suffered from persistent patellofemoral instability. Our technique preserves femoral and patellar insertion anatomy of MPFL using a free semitendinosus autograft, together with tenodesis to the adductor magnus tendon thus sparing the open physis of distal femur and the patellar attachment of MPFL. The clinical results were evaluated preoperatively and the final follow-up period using the Kujala patellofemoral score. Patellar shift, tilt and height were measured preoperatively and on the latest follow-up on plain radiographs. Results: At average 42 months follow-up ( range, 16 to 56), %80 of patients were satisfied with the treatment. Redislocation or instability symptoms occurred in two patients. No apprehension signs or redislocations were seen in the remanining six patients. A significant improvement (p&#x2039;0.05) in Kujala score (from 36 to 77) was found. Patellar shift & tilt decreased to anatomic values in six patients but patella alta persisted. Conclusion: The result of this study show that MPFL reconstruction with our technique seems to be an effective treatment for recurrent and habitual patellofemoral dislocation in skeletally immature patients; leading to significant increases in stability and functionality.

AbstractThe purpose of this study was to evaluate the outcomes of isolated medial patellofemoral ligament (MPFL) reconstruction, regardless of the presence of predisposing factors. A total of 21 knees that underwent isolated MPFL reconstruction from March 2014 to August 2017 were included in this retrospective series. Radiographs of the series of the knee at flexion angles of 20, 40, and 60 degrees were acquired. The patellar position was evaluated using the patellar tilt angle, sulcus angle, congruence angle (CA), and Caton-Deschamps and Blackburne-Peel ratios. To evaluate the clinical outcome, the preoperative and postoperative International Knee Documentation Committee (IKDC) and Lysholm knee scoring scales were analyzed. To evaluate the postoperative outcomes based on the predisposing factors, the results were separately analyzed for each group. Regarding radiologic outcomes, 20-degree CA was significantly reduced from 10.37 ± 5.96° preoperatively to −0.94 ± 4.11° postoperatively (p = 0.001). In addition, regardless of the predisposing factors, delta values of pre- and postoperation of 20-degree CA were not significantly different in both groups. The IKDC score improved from 53.71 (range: 18–74) preoperatively to 94.71 (range: 86–100) at the last follow-up (p = 0.004), and the Lysholm score improved from 54.28 (range: 10–81) preoperatively to 94.14 (range: 86–100) at the last follow-up (p = 0.010). Isolated MPFL reconstruction provides a safe and effective treatment for patellofemoral instability, even in the presence of mild predisposing factors, such as trochlear dysplasia, increased patella height, increased TT–TG distance, or valgus alignment. This is a Level 4, case series study.
