Patella instability is a clinical condition in which patella dislocation had occurred at least twice, or where patella instability following initial dislocation had persisted for more than three months. It can be unilateral or bilateral. Females are more affected, and it can affect the quality of life of the individual affected. This study is a retrospective survey of all patients who had recurrent patella dislocation at National Orthopedic hospital, Dala, Kano between January 2009 and November 2019. A total of 49 patients were treated with recurrent patella dislocation were found with a predominant young age (11-20 years-old) and a female preponderance (56.4%). Pain, instability or both are the main forms of presentation. Trauma, ligamentous laxity as well as hypoplasia of femoral condyle were risk factors identified. Arthroscopic medial plication and lateral release and was done in 28 (71.8%) patients as a means of treatment. Three patients (7.7%) had medial patellofemoral ligament reconstruction (MPFLR) while the remaining 8 patients (20.5%) were managed non-operatively.

Lateral dislocation of the patella is not uncommon and may impede daily activities as this causes compressive dysfunction and instabilities. Most cases of patellar lateral dislocation are due to damage to the medial patellofemoral ligament (MPFL), either rupture of detachment of the patella or femoral attachment. MPFL reconstruction alone was considered adequate for the treatment of this condition. We present a case of a 49-year-old male with chronic posttraumatic lateral patellar dislocation of the right knee of 25 years, which we treated with extensive lateral release and right medial patellofemoral ligament reconstruction with 5-year follow-up data.

Background: Recurrent patellar instability is commonly treated with medial patellofemoral ligament reconstruction (MPFLR), and the use of allograft in anterior cruciate ligament reconstructions has demonstrated inferior outcomes. Purpose: To compare the outcomes of allografts versus autografts in adolescent MPFLR for patellar instability. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective chart review was completed on patients younger than 18 years who underwent MPFLR for recurrent instability after failed nonoperative management over an 8-year period with a minimum 2-year follow-up. Patients were divided into autograft or allograft hamstring cohorts for comparison. Primary outcome measures were return to normal activity, incidence of redislocation/subluxation, pain, stiffness, other complications, and Kujala scores. Statistical analysis using unpaired t tests was performed, with an alpha value set at P < .05. Results: After criteria were applied, 59 adolescents (36 allograft, 23 autograft; 38 girls, 21 boys) with a mean ± SD age of 15.2 ± 1.7 years and a mean follow-up of 4.1 ± 1.9 years (allograft, 3.3 ± 1.1 years; autograft, 5.7 ± 2.1 years; P ≤ .001) were included. Seven patients had concurrent osteotomies (3 allograft, 4 autograft), 11 patients had concurrent loose body removals (5 allograft, 6 autograft), and 9 patients had concurrent lateral release (7 allograft, 2 autograft). Between groups, no significant difference was found in change between preoperative and most recent follow-up (mean, 1.2 ± 2.1) or rate of return to sports (mean, 73.3%). In total, 9 surgeries failed (3 allograft, 6 autograft). For the surviving grafts, a statistical difference in mean Kujala scores at final follow-up was noted (allograft, 92.7; autograft, 97.4; P = .02). Conclusion: We identified no significant differences in return to activity, pain score changes, and incidences of failure between patients undergoing MPFLR with allograft versus autograft. Although teenagers with surviving autograft MPFLR reported statistically higher Kujala scores, the mean score difference of 5 points was not clinically significant. It appears that using allograft tendon instead of autograft tissue for MPFLR in this teenage population does not adversely affect long-term outcomes.

Medial Patellofemoral Ligament Reconstruction

Abstract Patellofemoral instability is a common cause of knee pathology that is affecting the quality of life among pediatric population. Methods: We performed a prospective cohort study, including patients that underwent surgical management by using the Lateral Release and Medial Imbrication approach (LRMI) or Medial Patellofemoral Ligament Reconstruction (MPFL-R). The purpose of this study was the assessment of the quality of life among pediatric population that underwent surgery for patellar dislocation. The quality of life was evaluated before and after surgery using the Pediatric International Knee Documentation Committee form (Pedi-IKDC). The postoperative scar was evaluated using The Stony Brook Scar Evaluation Scale. 108 patients were selected and grouped according to the type of procedure. Results: before surgery, the calculated Pedi-IKDC scores were similar between the two groups of patients. We identified substantial improvement in the postoperative score after surgery and the Medial Patellofemoral Ligament Reconstruction technique showed better results. The difference regarding the Pedi-IKDC score between the two groups was significant, in favor of the Medial Patellofemoral Ligament Reconstruction. By using the Stony Brook Scar Evaluation Scale, an important difference emerged between the two groups of patients in favor of the Medial Patellofemoral Ligament Reconstruction technique, revealing that it is a minimally invasive approach, improves recovery, reduces postoperative stay and increases the patients quality of life.Conclusions: This study provides further evidence based results that support the recommendations regarding the Medial Patellofemoral Ligament Reconstruction technique as the gold standard for the patellofemoral instability.Trial registration: The Ethics Committee of „Grigore Alexandrescu” Children’s Emergency Clinical Hospital of Bucharest approved this study on 1st of March 2013. The project code is 7/01.03.2013. An informed parental consent was obtained for every participant.
