[Ab] Abstract:A 29-year-old patient, suffering from DiGeorge syndrome, came to our attention with a history of persistent pain and patellar instability in the left knee after failure of arthroscopic lateral release and Elmslie-Trillat procedure. The patient was unable to walk without crutches and severely limited in daily living activities. Because of arthritic changes of the patellofemoral joint and the failure of previous surgeries it was decided to perform only an open lateral release and medial patellofemoral ligament (MPFL) reconstruction using a biosynthetic ligament in order to obtain patellofemoral stability. At one year post-op range of motion (ROM) was 0-120 with a firm end point at medial patellar mobilization; patella was stable throughout the entire ROM. All the scores improved and she could be able to perform daily activity without sensation of instability. Bilateral patellar subluxation and systemic hyperlaxity are characteristics of syndromic patients and according to literature can be also present in DiGeorge syndrome. MPFL reconstruction with lateral release was demonstrated to be the correct solution in the treatment of patellar instability in this complex case. The choice of an artificial ligament to reconstruct the MPFL was useful in this specific patient with important tissue laxity due to her congenital syndrome.

[Ab] Abstract:OBJECTIVE: The purpose of this case study is to describe the evaluation and management of patellar dislocations and the different approaches used from providers in different countries. CLINICAL FEATURES: An individual dislocated her left patella while traveling abroad and received subsequent care in Thailand, China, and the United States. INTERVENTION AND OUTCOME: Nonoperative treatment protocols including manual closed reduction of the patella, casting of the leg, and rehabilitation exercises were employed. CONCLUSION: Receipt of care when abroad can be challenging. The patient's knee range of motion and pain continued to improve when she was diligent about performing the home exercise program. This case highlights the importance of a thorough examination, a proper regimen of care, and patient counseling to ensure a full recovery and minimize the chance of re-injury.

[Ab] Abstract:PURPOSE: To examine the cartilage quality in young adults with recurrent patellar dislocation in childhood using different magnetic resonance imaging parameters. METHODS: Sixteen young adults with unilateral recurrent patellar dislocation were investigated ≥5 y (mean, 8.5 y) after the first dislocation. Pre- and postcontrast T1 and precontrast T2 relaxation times were analyzed in four superficial and four deep patellar cartilage regions of both knees. Two hours after intravenous injection of 0.2 mM/kg Gd-DTPA(2-), postcontrast T1 [T1(Gd)] and ΔR1 [1/T1 (precontrast) - 1/T1 (postcontrast)] were analyzed in the regions. Muscle performance and patient-reported outcome were evaluated. RESULTS: When comparing the injured side with the noninjured side, differences were seen in the superficial half but not the deep half of the cartilage. T1(Gd) was shorter in the central part, whereas T2 was shorter in the periphery of the patellar cartilage (P < 0.05). ΔR1 demonstrated similar differences between healthy and diseased cartilage as T1(Gd) alone. The knee function was not correlated to the degenerative changes. CONCLUSION: The short T1(Gd) centrally indicates degenerative cartilage changes consistent with loss of glycosaminoglycans. Precontrast and ΔR1 calculations may be excluded in clinical dGEMRIC, which simplifies the procedure. A decrease in T2 may be a very early sign of joint pathology but warrants further investigation.

[Ab] Abstract:PURPOSE: This animal study aimed to investigate whether early reduction in patellar subluxation could minimize femoral trochlear dysplasia in growing rabbits. METHODS: Sixty rabbits were divided into four groups (N = 30 knees/group). The control group underwent no surgical procedures. The rabbits in the three experimental groups underwent surgical patellar subluxation. Those in the early-reduced group underwent reduction surgery 1 month after patellar subluxation. The late-reduced group underwent reduction surgery 2 months after patellar subluxation. The rabbits in the non-reduced group underwent no reduction surgery. CT scans were performed monthly to measure the sulcus angle and trochlear width and depth. Gross specimen examination and histological observation were performed to investigate anatomical configuration and changes in the trochlear groove cartilage. RESULTS: CT scans demonstrated significant differences in the sulcus angle, trochlear width and trochlear depth by 6 months after subluxation surgery in the late-reduced and non-reduced groups. No obvious differences in these parameters were seen in the early-reduced group compared with the control group. Gross specimen examination and histological investigations showed degenerative changes in the femoral trochlear groove and cartilage by 6 months after subluxation surgery in the late-reduced and non-reduced groups. No degenerative changes were found in the early-reduced group, compared with the control group. CONCLUSION: Our results indicate that patellar subluxation or dislocation early in an animal's development can lead to femoral trochlear dysplasia or flattening and that early relocation of the patella can prevent femoral trochlear dysplasia in growing rabbits.

[Ab] Abstract:PURPOSE: There is only one prospective randomized trial on acute primary patellar dislocation in adolescents comparing the long-term outcome after conservative versus operative procedures. Therefore, the long-term outcome, patellar redislocation rate, and functional outcome after conservative versus operative procedures were investigated in a prospective randomized study. METHODS: Initially, 36 patients with acute primary patellar dislocation were prospectively randomized to conservative (n = 20) versus operative procedures (n = 16) and 30 of them (83 %), 15/20 with conservative and 15/16 with operative procedures, were reached for a follow-up interview 6 years after primary procedure. RESULTS: Baseline and clinical parameters were similar in the two groups. The prevalence of patellar redislocation rate at 3 and 6 years after primary procedure was higher in the conservative group (7/20, 35 %, 3 years and 11/15, 73 %, 6 years) versus in the operative group (0/16, 0 %, 3 years and 5/15, 33 %, 6 years) (p = 0.02). The knee function was slightly better 6 years after primary treatment in the operative group than in the conservative group. Most patients in both groups had excellent or good knee function at 6-year follow-up, but four patients (4/15, 27 %) in conservative group and two patients (2/15, 13 %) in operative group had poor knee function at 6-year follow-up. Four patients in conservative group (4/15, 27 %) and two patients in the operative group (2/15, 13 %) were unsatisfied with the procedure at 6-year follow-up. CONCLUSIONS: In conclusion, the results suggest that both conservative and operative procedures are feasible options for treatment of acute primary patellar dislocation in adolescents. A new finding with clinical relevance in the present work is a significantly higher redislocation rate in conservative group compared to operative group after 6-year follow-up in acute primary patellar dislocation in adolescents. LEVEL OF EVIDENCE: II.

[Ab] Abstract:Constrained total knee prostheses are used in knees with severe deformities and insufficiency of col- laterals to provide stable and mobile knees. Dislocation after constrained knee prosthesis is an extremely rare and dreaded complication. When dislocation is associated with patellar tendon rupture, the man- agement includes restoration of the extensor apparatus along with a stable knee. Repair of the patellar tendon is challenging due to poor soft tissue coverage in the area and a bulky repair can put tension on the wound closure. Ideal method of restoration of the extensor apparatus is a matter of debate. There are various modalities used ranging from primary end-to-end repair, augmentation by medial gastrocnemius flap, semitendinosus and synthetic implants and allograft tendoachilles. We report a rare case of a posterior dislocation of a constrained total knee arthroplasty in association with patellar tendon rupture due to a minor fall after a few weeks of surgery. The first episode was managed by reposition of the dislocation and VeY plasty of the quadriceps and primary repair. The second episode of dislocation with re-rupture needed augmentation by semitendinosus along with the insertion of the thicker insert. The management of this complex problem along with the review of literature is discussed in this case report.

[Ab] Abstract:INTRODUCTION: Patellar instability is a condition with multifactorial aetiology, potentially involving soft tissue characteristics, the bony anatomy of the patella, femur and tibia, and alignment of the lower limb. The shape of the distal femur and patellofemoral joint has been frequently studied using plain orthogonal and skyline radiographs. We investigated a possible contribution of hypoplasia of the lateral femoral condyle in the axial plane to patellar instability. METHODS: The geometry of the distal femur and alignment of the lower limb on plain radiographs and MRI scans in 25 young adult patients with patellar instability was measured, and compared to a control group of 75 age-matched patients. Measurements were validated by intra-observer and inter-observer reliability studies, and multivariate analysis was used to compare the groups. Cases with and without high Beighton score or knee hyperextension were also compared. RESULTS: The anatomical posterior condylar angle, anterior condylar angle and sulcus angle on axial MRI scans showed insignificant differences between groups. The Blackburne-Peel ratio, anatomical femoro-tibial angle and femoral joint angle showed significant differences between groups, but not the tibial plateau angle. There was a significant correlation between posterior condylar angle and valgus knee alignment. In cases with joint hypermobility, femoral joint angle was significantly increased and posterior condylar angle was significantly decreased. CONCLUSIONS: Multiplanar hypoplasia of the lateral femoral condyle resulting in a valgus knee is a risk factor for patellar instability in young patients without osteoarthritis or joint hypermobility. Isolated posterior lateral condyle hypoplasia appears to be unrelated to patellar instability.

[Ab] Abstract:BACKGROUND: Multiligament knee injuries (MLKIs) can also involve the medial patellofemoral ligament (MPFL), but there is a paucity of information regarding prevalence and relevance of MPFL involvement in this setting. PURPOSE: (1) To identify the prevalence of MPFL injury in MLKIs, (2) to determine whether an MPFL tear results in symptomatic patellar instability, and (3) to report clinical and functional outcomes of patients with and without MPFL tears after MLKI surgical reconstruction. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The records of all patients who underwent surgical reconstruction of MLKI (defined as a grade 3 injury of ≥2 ligaments) at a single institution from 2007 to 2010 were reviewed. Age, sex, knee dislocation classification (according to Schenck), and MRI findings were documented. All preoperative MRI scans were reviewed by an experienced musculoskeletal radiologist to determine the presence or absence of MPFL involvement. If an MPFL tear was present, its anatomic location and severity as well as the presence of patellar or lateral femoral condyle bone bruises were documented. Inclusion criteria included (1) MLKI treated at a single institution, (2) presence of MPFL tear on preoperative MRI, and (3) minimum 2-year clinical follow-up. Patellar instability symptoms were assessed with the Kujala Knee Questionnaire. Functional outcomes were measured using the International Knee Documentation Committee (IKDC) score. IKDC scores were compared between patients who sustained MLKIs with and without MPFL tears. There were 21 patients in each group. RESULTS: Over the 4-year study period, 30 of 51 patients (59%) treated surgically for a MLKI had MRI evidence of an MPFL tear. Nine were lost to follow-up, leaving 21 patients for review. There were 13 complete (62%), 5 high-grade partial (24%), and 3 partial (14%) MPFL tears. Sixteen of 21 tears (76%) occurred at the proximal third, with the remainder exhibiting diffuse signal abnormality consistent with tearing throughout the length of the MPFL. The superficial medial collateral ligament was involved in all patients. In no case was the MPFL repaired or reconstructed. At mean follow-up of 3.6 years (range, 2.0-5.7 years), only 1 of 21 patients (5%) complained of patellofemoral instability symptoms whereas 20 of 21 patients (95%) did not experience patellar subluxation or dislocation. No significant difference was found when IKDC scores were compared between patients with and without an MPFL tear (mean ± SD, 65.5 ± 22.9 vs 79.4 ± 16.1; P = .07). CONCLUSION: MPFL tears occur frequently in patients with MLKI but rarely cause instability. In the majority of cases, MPFL tears do not need to be addressed at the time of surgery.

[Ab] Abstract:INTRODUCTION: Trochlear dysplasia is one of the main elements of patellofemoral instability. Although correction by trochleoplasty seems logical, the long-term outcome of this procedure is unknown and the progression to osteoarthritis has not been clarified. Thus, we performed a retrospective study of a series of sulcus deepening trochleoplasties with a 15-year follow-up whose goal was to (1) evaluate the long-term clinical outcome and radiological rate of osteoarthritis, and (2) define the results in relation to the type of instability and the grade of dysplasia. HYPOTHESIS: Sulcus deepening trochleoplasty is an effective procedure to stabilize the patellofemoral joint that does not increase the risk of osteoarthritis. PATIENTS AND METHODS: This retrospective study analyzed 34 sulcus deepening trochleoplasties based on clinical scores (IKS, Lille, Kujala and Oxford scores) and radiological results (stage of osteoarthritis according to the Iwano score) after a mean follow-up of 15 years (12-19 years). An Insall procedure was systematically associated with an anterior tibial tubercle transfer in 17 cases (7 prior tibial transfers). RESULTS: No recurrent objective instability was observed. Seven knees had additional surgery after a mean follow-up of 7 years (2-16): 7 underwent conversion to total knee arthroplasty because of progression of osteoarthritis and one knee had tibial tubercle transfer for pain and episodes of the knee giving way. The mean Lille, Kujala and IKS scores increased from 53.3 (30-92), 55 (13-75) and 127 (54-184) to 61.5 (25-93), 76 (51-94) and 152.4 (66-200) respectively between preoperative and follow-up assessment (P<0.05) (revisions included). Functional outcome was significantly better for dysplasia with supratrochlear spurs (IKS score 168 [127-200] versus 153 [98-198] and Kujula score 81.5 [51-98] versus 76 [51-94] [P<0.05]). Patients were satisfied in 65% of the cases and the total mean Oxford score was 24.1/60 (12-45 points). Occasional pain was present in 53% of the cases. The trochlear prominence decreased from 4.9 mm (3-9 mm) to -1.2mm (-7-4mm). Ten cases of preoperative patellofemoral osteoarthritis were identified, but none with>Iwano 2, while osteoarthritis was present in 33/34 cases at the final follow-up with 20 cases>Iwano 2 (65%). DISCUSSION: Sulcus deepening trochleoplasty corrects patellofemoral stability even in patients with severe dysplasia and the long-term functional outcome is better in this group. It does not prevent patellofemoral osteoarthritis. It should be limited to severe dysplasia with supratrochlear spurs and associated with procedures to realign the extensor apparatus.

[Ab] Abstract:OBJECTIVE: To investigate the procedure and efficacy of anatomical medial patellofemoral ligament (MPFL) reconstruction for the treatment of recurrent patellar dislocation assisted with arthroscopy.
 METHODS: Between January, 2010 and December 2012, 13 patients with recurrent patellar dislocation, who underwent anatomical MPFL reconstruction and the grafts of operation, were all adopted with autograft semitendinosus. The patellar side used the modified double bone tunnels and the minimally invasive percutaneous grafts through double patellar bone tunnels, and then fixed in the femoral tunnel with absorbable interference screw. Follow-up included the records of the subjective feeling, patellar apprehension test, recurrent dislocation, CT evaluation of bone tunnel position and patellar tilt angle. Knee function was evaluated by the Lysholm score and Kujala score. 
 RESULTS: Twelve patients were followed up for 36 months (range 24-60 months). All patients were satisfied with the treatment. No recurrent dislocation occurred. All the patients showed negative apprehension test. Two patients felt uncomfortable after excessive activity in the knee. Another 2 cases lost 10° flexion than the healthy knee. CT showed that the bone tunnel position were all well. The patellar tilt angle was decreased from 20.52°±1.48° preoperative to 13.52°±1.32° postoperative, with significant difference (t=14.88, P<0. 05); the Kujala score was improved from 55.2±4.51 preoperative to 93.8±3.87 postoperative, with significant difference (t=-36.238, P<0.05); and the Lysholm score was improved from 56.68±5.52 to 93.08±4.68, with significant difference (t=-33.382, P<0.05). 
 CONCLUSION: MPFL reconstruction assisted with arthroscopy is an effective surgical procedure for the treatment of recurrent patellar dislocation, which can improve the knee function with little trauma and complications.
