[Ab] Abstract:OBJECTIVE: To investigate the clinical therapeutic results of allograft tendon for anatomical reconstruction of medial patellofemoral ligament (MPFL) for the treatment of patellar dislocations. METHODS: From September 2008 to June 2013, 16 patients with patellar dislocation underwent MPFL reconstructions. There were 2 males and 14 females, aged 11 to 27 years old (16 years old on average). Patellar dislocations occurred in 11 left and 5 right knees. The disease course ranged from 3 to 10 years. The frequency of dislocation ranged from 9 to 33 times (19 times on average). Affected knee joints showed patellar instability; the range of action for patella obviously increased. The X-ray films showed patellar dislocation. The preoperative Q angle was (36 ± 9)°, and the congruence angle was (63 ± 18)°. Reconstruction was performed via allograft tendon. Allograft tendon was fixed through the superomedial pole of the patella, and the other end was fixed at the natural MPFL insertion site near the medial femoral condyle with an interference screw in a bone tunnel. All the patients were evaluated postoperatively; Kujala patellofemoral scores, objective knee function, complications, and reoperations were assessed. RESULTS: Primary healing was achieved in all cases. No infection or necrosis and absorption of grafts was observed. All the patients were followed up for an average of 16.4 months (ranged, 10 to 24 months) postoperatively. At the latest follow-up, all the patients had no pain, swelling and patellar instability; neither patella redislocation nor fracture occurred. The X-ray films showed good position of tunnel 6 months after operation, and the congruence angle was (5 ± 9)°, showing statistically significant difference when compared with preoperation (P < 0.05). The postoperative Q angle was (17 ± 8)°, the Kujala knee function score improved significantly from 45.20 ± 9.20 to 89.30 ± 6.40 at the latest follow-up, showing statistically significant difference (P < 0.05). CONCLUSION: MPFL reconstruction improves clinical symptoms. Anatomical MPFL reconstruction is effective for patellar dislocation, and it offers good recovery of the premorbid patella mechanics. The interference screw provides firm fixation. Allograft can avoid the graft harvest site morbidity, but it increases the cost of the surgery.

[Ab] Abstract:OBJECTIVE: To explore the effectiveness of hamstring tendon graft embedding reconstruction of medial patellofemoral ligament for the treatment of recurrent dislocation of the patella. METHODS: From March 2008 to June 2013,67 patients with recurrent dislocation of patella were treated, including 28 males, 39 females with an average age of 22 years ranging from 10 to 42 years old. The clinical manifestations involved knee joint instability,"giving way", sense of patellar dislocation, anterior knee pain. All 67 patients underwent arthroscopic hamstring tendon graft embedding reconstruction of the medial patellofemoral ligament. The curative effect were evaluated by preoperative and postoperative Lysholm score and Q angle changes. RESULTS: All cases were followed up after operation and the mean follow-up time was(27.5±13.4) months(4 to 69 months). Postoperative incision were healed well and no patellar dislocation or subluxation occurred. Lysholm score improved from preoperative 76.35±2.86 to 82.71±2.29 postoperatively; Q angle decreased from preoperative (18.75±2.33)° to postoperative(13.28±1.75)°. CONCLUSION: The method for the reconstruction of medial patellofemoral ligament can provide enough tension, patellar stability.imoroving the function of knee ioint.

[Ab] Abstract:An increased tibial tubercle-trochlear groove (TT-TG) distance is related to patellar maltracking and instability. Tibial tubercle transfer is a common treatment option for these patients with good short-term results, although the results can deteriorate over time owing to the progression of osteoarthritis. We present a ten-year follow-up study of a self-centring tibial tubercle osteotomy in 60 knees, 30 with maltracking and 30 with patellar instability. Inclusion criteria were a TT-TG ≥ 15 mm and symptoms for > one year. One patient (one knee) was lost to follow-up and one required total knee arthroplasty because of progressive osteoarthritis. Further patellar dislocations occurred in three knees, all in the instability group, one of which required further surgery. The mean visual analogue scores for pain, and Lysholm and Kujala scores improved significantly and were maintained at the final follow-up (repeated measures, p = 0.000, intergroup differences p = 0.449). Signs of maltracking were found in only a minority of patients, with no difference between groups (p > 0.05). An increase in patellofemoral osteoarthritis was seen in 16 knees (31%) with a maximum of grade 2 on the Kellgren-Lawrence scale. The mean increase in grades was 0.31 (0 to 2) and 0.41 (0 to 2) in the maltracking and instability groups respectively (p = 0.2285) This self-centring tibial tubercle osteotomy provides good results at ten years' follow-up without inducing progressive osteoarthritis.

[Ab] Abstract:Various pathologies of the hip or knee, such as patellofemoral malalignment or femoroacetabular impingement may be caused by a femoral torsional deformity. When diagnosed and analyzed, it is treated by femoral torsional osteotomy. Thirty femoral torsional osteotomies in 25 patients were included, the principal symptoms were patellar dislocation in 15 patients, anterior knee pain in 17, and femoroacetabular impingement in two. A computed-tomography-based measurement of the torsional angle was performed in all patients. Japanese Knee Society score, Tegner activity score, Lysholm score, and visual analog scale score were determined before surgery and at follow-up after 41 (6-113) months. Femoral internal torsion was on average 40.9° (29° - 66°; normal 24°). Surgical treatment consisted of a femoral external torsional osteotomy of on average 13.8° (5° - 26°). Tegner activity score increased non-significantly (p-value 0.326) from 3.57 to 3.71. Japanese Knee Society score improved significantly from 72 to 87 (p-value 0.004) while Lysholm score rose significantly from 66 to 84 points (p-value 0.004). Pain relief was demonstrated by a significant decrease in the VAS score from 5.6 to 2.4 (p-value 0.007). No further patellar dislocation was reported. Torsional deformities of the femur frequently cause symptoms in the knee or hip joint. After thorough assessment and diagnostic investigation, a femoral external torsional osteotomy provides significant pain relief as well as patellofemoral stability.

[Ab] Abstract:BACKGROUND: Patellar dislocation occurs when the patella disengages completely from the trochlear (femoral) groove. Following reduction of the dislocation, conservative (non-surgical) rehabilitation with physiotherapy may be used. Since recurrence of dislocation is common, some surgeons have advocated surgical intervention rather than non-surgical interventions. This is an update of a Cochrane review first published in 2011. OBJECTIVES: To assess the effects (benefits and harms) of surgical versus non-surgical interventions for treating people with primary or recurrent patellar dislocation. SEARCH METHODS: We searched the Cochrane Bone, Joint and Muscle Trauma Group's Specialised Register, the Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, AMED, CINAHL, ZETOC, Physiotherapy Evidence Database (PEDro) and a variety of other literature databases and trial registries. Corresponding authors were contacted to identify additional studies. The last search was carried out in October 2014. SELECTION CRITERIA: We included randomised and quasi-randomised controlled clinical trials evaluating surgical versus non-surgical interventions for treating lateral patellar dislocation. DATA COLLECTION AND ANALYSIS: Two review authors independently examined titles and abstracts of each identified study to assess study eligibility, extract data and assess risk of bias. The primary outcomes we assessed were the frequency of recurrent dislocation, and validated patient-rated knee or physical function scores. We calculated risk ratios (RR) for dichotomous outcomes and mean differences MD) for continuous outcomes. When appropriate, we pooled data. MAIN RESULTS: We included five randomised studies and one quasi-randomised study. These recruited a total of 344 people with primary (first-time) patellar dislocation. The mean ages in the individual studies ranged from 19.3 to 25.7 years, with four studies including children, mainly adolescents, as well as adults. Follow-up for the full study populations ranged from two to nine years across the six studies. The quality of the evidence is very low as assessed by GRADE (Grading of Recommendations Assessment, Development and Evaluation Working Group) criteria, with all studies being at high risk of performance and detection biases, relating to the lack of blinding.There was very low quality but consistent evidence that participants managed surgically had a significantly lower risk of recurrent dislocation following primary patellar dislocation at two to five years follow-up (21/162 versus 32/136; RR 0.53 favouring surgery, 95% confidence interval (CI) 0.33 to 0.87; five studies, 294 participants). Based on an illustrative risk of recurrent dislocation in 222 people per 1000 in the non-surgical group, these data equate to 104 fewer (95% CI 149 fewer to 28 fewer) people per 1000 having recurrent dislocation after surgery. Similarly, there is evidence of a lower risk of recurrent dislocation after surgery at six to nine years (RR 0.67 favouring surgery, 95% CI 0.42 to 1.08; two studies, 165 participants), but a small increase cannot be ruled out. Based on an illustrative risk of recurrent dislocation in 336 people per 1000 in the non-surgical group, these data equate to 110 fewer (95% CI 195 fewer to 27 more) people per 1000 having recurrent dislocation after surgery.The very low quality evidence available from single trials only for four validated patient-rated knee and physical function scores (the Tegner activity scale, KOOS, Lysholm and Hughston VAS (visual analogue scale) score) did not show significant differences between the two treatment groups.The results for the Kujala patellofemoral disorders score (0 to 100: best outcome) differed in direction of effect at two to five years follow-up, which favoured the surgery group (MD 13.93 points higher, 95% CI 5.33 points higher to 22.53 points higher; four studies, 171 participants) and the six to nine years follow-up, which favoured the non-surgical treatment group (MD 3.25 points lower, 95% CI 10.61 points lower to 4.11 points higher; two studies, 167 participants). However, only the two to five years follow-up included the clear possibility of a clinically important effect (putative minimal clinically important difference for this outcome is 10 points).Adverse effects of treatment were reported in one trial only; all four major complications were attributed to the surgical treatment group. Slightly more people in the surgery group had subsequent surgery six to nine years after their primary dislocation (20/87 versus 16/78; RR 1.06, 95% CI 0.59 to 1.89, two studies, 165 participants). Based on an illustrative risk of subsequent surgery in 186 people per 1000 in the non-surgical group, these data equate to 11 more (95% CI 76 fewer to 171 more) people per 1000 having subsequent surgery after primary surgery. AUTHORS' CONCLUSIONS: Although there is some evidence to support surgical over non-surgical management of primary patellar dislocation in the short term, the quality of this evidence is very low because of the high risk of bias and the imprecision in the effect estimates. We are therefore very uncertain about the estimate of effect. No trials examined people with recurrent patellar dislocation. Adequately powered, multi-centre, randomised controlled trials, conducted and reported to contemporary standards, are needed. To inform the design and conduct of these trials, expert consensus should be achieved on the minimal description of both surgical and non-surgical interventions, and the anatomical or pathological variations that may be relevant to both choice of these interventions and the natural history of patellar instability. Furthermore, well-designed studies recording adverse events and long-term outcomes are needed.

[Ab] Abstract:PURPOSE: The aim of this review was to compare the clinical outcomes between operative and conservative management for primary patella dislocation (PPD). METHODS: PubMed Medline, EMBASE, Google scholar, and the Cochrane Library were systematically searched for randomized controlled trials that compared operative technique versus conservative technique for PPD. The results of eligible studies were independently extracted and analyzed according to the following: patient's satisfaction, Kujala score, Tegner score, and redislocation rate. Random-effect and fixed-effect models were adopted to calculate the weight mean difference and the odds ratio for continuous and dichotomous variables with 95 % confidence interval. RESULTS: Seven studies met the inclusion criteria, resulting in 402 (216 surgery and 186 conservation) patients available for the present study. A meta-analysis showed no significant differences between the two treatment groups in terms of patient's satisfaction and Kujala score. However, significant differences in Tegner score (P < 0.00001) and redislocation rate (P = 0.002) were observed in favor of surgical treatment. In the subgroup analysis, surgical intervention achieved higher (P = 0.002) Kujala score in short term (<5 years), while conservation gained advantage (P = 0.003) in long term (>5 years). There was no significant difference in dislocation rate in long term. CONCLUSIONS: Surgical treatment might provide better clinical results in short term. More persuasive evidence is still needed to proof the effect of surgical management in long time.

[Ab] Abstract:Recurrent dislocation of the patella is a common orthopaedic problem which occurs in about 44% of cases after first-time dislocation. In most cases of first-time patellar dislocation, the medial patellofemoral ligament (MPFL) becomes damaged. Between 2010 and 2012, 33 children and adolescents (39 knees) with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon. The aim of our study is to assess the effectiveness of this surgical procedure. The outcomes were evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination) and radiographically (Caton index, sulcus angle, congruence angle, and patellofemoral angle). Four patients demonstrated redislocation with MPFL graft failure, despite the fact that patellar tracking was found to be normal before the injury, and the patients had not reported any symptoms. Statistically significant improvements in Lysholm and Kujala scales, in patellofemoral and congruence angle, were seen (P < 0.001). A statistically significant improvement in the peak torque of the quadriceps muscle and flexor was observed for 60°/sec and 180°/sec angular velocities (P = 0.01). Our results confirm the efficacy of MPFL reconstruction using the adductor magnus tendon in children and adolescents with recurrent patellar dislocation.

[Ab] Abstract:OBJECTIVES: To assess whether the bisection of the fabellae by their respective femoral cortices is a useful criterion for assessing positioning of craniocaudal pelvic limb radiographs, and whether this is consistent in limbs affected or unaffected by medial patella luxation. METHODS: Computed tomography multi-planar reconstructions were used to determine the relative positions of the fabellae with respect to the femoral cortices. RESULTS: Only 36% of fabellae overall were bisected by the femoral cortex. There was no significant difference between limbs affected or unaffected by medial patella luxation. CLINICAL SIGNIFICANCE: The accurate measurement of femoral varus angle is important in pre-surgical planning of distal femoral ostectomy. Radiography is normally used to obtain the femoral varus angle, and femoral rotational malpositioning will induce errors in the femoral varus angle measured. Bisection of the fabellae by the femoral cortices is commonly cited as a criterion by which to assess whether a radiographic projection is truly craniocaudal, yet this study has shown this not to be valid.

[Ti] Title:Medial patellofemoral ligament anatomy: is it a predisposing factor for lateral patellar dislocation?

[La] Language:eng
[Ab] Abstract:PURPOSE: Because the medial patellofemoral ligament (MPFL) is the primary restraint to lateral dislocation of the patella, we aimed, in this controlled study, to verify whether the MPFL with different measurements could be considered another predisposing factor for patellar dislocation. METHODS: A group of 100 consecutive individuals without the criteria for patellar dislocation (trochlear dysplasia, patella alta and lateral patellar tilt) was recruited as a control group and underwent magnetic resonance imaging (MRI) study and another group of 50 patients with patellar instability. Femoral condyles, interepicondylar distance, length and thickness of the MPFL were measured. RESULTS: In the control group, the MPFL was 38-60 mm long. Individuals with patellar instability who had no episode of patellar dislocation had a 4.11-mm longer ligament than controls (p = 0.032), while patients with instability with a previous history of dislocation had a 13.54-mm longer MPFL than controls (p < 0.001). Thickness of the MPFL at the patellar insertion was lower in individuals with patellar instability with a history of dislocation (p < 0.001). An instability coefficient (IC) less than 1.3 indicates that the MPFL is insufficient. CONCLUSIONS: Individuals with patellar instability and previous patellar dislocation present with longer MPFL when compared to controls, and an associated IC less than 1.3 can be considered a predisposing factor for patellar dislocation. Treatment of patellar instability is a challenge, and it is difficult to identify what is the predisposing factor. This study has verified the measurements of the MPFL for the first time and presents values of thickness and length that can be considered as indications for surgical reconstruction.

[Ab] Abstract:In addition to ultrasound and conventional x-ray, magnetic resonance imaging (MRI) plays an important role in the visualization of lesions of the knee. It allows the orthopaedic surgeon to safely detect ruptures of the cruciate ligaments, the meniscus, osteochondral lesions and other ligamentary structures such as the collateral ligaments and the medial patellofemoral ligament (MPFL). In patellar dislocations, risk factors for recurrent dislocations can be determined and the therapy can be adjusted accordingly.This articles aims to give the reader a comprehensive overview on current concepts and techniques in the use of MRI for lesions of the knee. It focuses on patellar dislocations, where MRI plays a dominant role in supporting decision making for the best therapeutic strategy.
