Medial patellofemoral ligament (MPFL) reconstruction is a satisfactory technique for patellar instability, and the anatomical double bundle variant is recommended for better clinical results. However, long-term outcomes are still uncharacterized. This study aimed to assess the effectiveness of double bundle reconstruction of the MPFL for patellar instability by means of established scores. A total of 68 patients with chronic patellar instability who underwent surgery from May 2005 to February 2010 were included prospectively. Anatomical double reconstruction of the MPFL with the semitendinosus tendon was conducted. Tegner Activity Scale (TAS), Kujala score, Lysholm knee score, and objective physical examination were assessed during follow-up. Median follow-up time for the patients was 8 (range, 6–10) years. Eight patients were lost to follow-up after 2 years. Preoperative mean TAS was 2.85 ± 0.78, increased to 4.91 ± 0.84 at 6 months and 7.26 ± 0.78 at 2 years postoperatively, and was 7.82 ± 0.89 at last follow-up. At last follow-up, pain free at rest was achieved in all patients; and 8 patients had knee pain in activities of daily living. Mean Kujala score was 57.53 ± 8.59 preoperatively, and increased to 61.22 ± 6.46, 89.51 ± 3.90, and 88.92 ± 3.84 at 6 months, 2 years postoperatively, and at last follow-up, respectively. Lysholm scores were also increased from preoperative values of 43.53 ± 10.20 to 58.22 ± 6.80, 89.37 ± 4.38, and 89.67 ± 4.13 at 6 months, 2 years postoperatively, and at last follow-up, respectively. Range of motion was 121.44 ± 12.69, 129.71 ± 6.39, 130.93 ± 5.67, and 130.78 ± 5.80 at preoperative point, 6 months, 2 years postoperatively, and at last follow-up, respectively. Long-term clinical results of double bundle reconstruction of the MPFL for patellar instability were encouraging.

Objectives: Patellar instability is common in adolescents during their growth. Management of the actual patellar instability at the time of arthroscopic treatment for concomitant intra-articular loose body has been debated since many surgeons will manage first-time dislocations without surgery. To demonstrate that medial patellofemoral joint reconstruction, rather than neglect or repair of the ligament, should be performed at the time of arthroscopic loose body removal for first-time patellar instability events in children. Methods: Retrospective study design was performed on all patients who sustained a patellar instability event that resulted in an intra-articular loose body between 2011 and 2017 at our institution. Data was collected using ICD-9/10 and/or CPT codes. Patients included in the analysis were required to have a minimum of 24 month follow-up documented. We then performed chart review and radiographic review (XR and MRI). Variables collected included: demographics, weight, BMI, pain score, SANE score, Kujala score, subsequent recurrent instability, need for second surgery, growth plate status, trochlear dysplasia, TT-TG, Insall-Salvati ratio, and Blackburne-Peel ratio. Data analysis pooled the “neglect” and “repair” groups together and compared it to the “reconstruction” group. Continuous variables were examined for normal distribution and homogeneity and analyzed with ANOVA or Mann Whitney. Chi square was utilized for categorical variables. Results: 64 patients (34 males, 30 females) with a mean age at surgery of 14 years (range 9 to 18) met criteria. These participants had a reported mean weight (kg) and BMI of 67.6 kg and 23.9, respectively. In our two-cohort analysis, the reconstruction cohort demonstrated significantly less subsequent instability, with the rate of recurrence being 58.7% in the neglect/repair compared to 16.7% in the reconstruction group (p=0.002). In addition, the reconstruction group demonstrated significantly less patients that required second surgery (p=0.024). The only continuous variable that showed any statistically significant difference was the Insall-Salvati ratio (p=0.048) with the reconstruction group being a mean 1.3 versus a mean 1.4 in the neglect/ repair group. There was no difference was found for age, weight, BMI, Blackburn ratio, TDI, TT-TG, Pain, SANE, Kujala score, satisfaction, or length of follow-up. Conclusion: Medial patellofemoral ligament reconstruction in the setting of adolescent patellar instability with an intra-articular loose body results in significantly less recurrent instability and reduced need for subsequent surgery compared to those who do not undergo a concomitant ligament reconstruction.

Objectives: The incidence of acute femoro-patellar luxation is 6/100000 persons for year. This injury is common among young patients with predominance in women. It has high levels of recurrence (40%) after the first injury. The objective of our study is to assess post-surgical results in patients with relapsing patellar dislocation, after a reconstruction of Medial Patellofemoral Ligament (MPFL) with semitendinous autologous graft associated with autologous osteochondral transplant of patella. Methods: An observational descriptive study (cases serie) with a restrospective transversal cross section was carried out. Six male patients that were treated between March 2014 and March 2016 were evaluated. They were monitored / followed up in an average of 24 months. The functional subjective results were assessed following Kujala patellofemoral pain score. Results: Out of the six patients, all of them were male, with an average age of 19. They were followed-up for an average of 24 months. The results of the Kujala score were 86 points in the posoperative period. Conclusion: The reconstruction of Medial Patellofemoral Ligament (MPFL) with semitendinous autologous graft associated with autologous osteochondral transplant of patella has show excellent short and long-term clinical results with return of patients to their usual normal activities.

Abstract The present study aimed to introduce a novel technique to reconstruct medial patellofemoral ligament (MPFL) via arthroscopy for recurrent patellar dislocation. A retrospective review of a prospectively collected registry was undertaken. A total of 34 patients (35 knees) who underwent arthroscopic reconstruction of MPFL from December 2017 to August 2019 were identified. Kujala score, Tegner score, Lyscholm score, patellar tilt, and congruence angle were recorded preoperatively and postoperatively. The occurrences of patient satisfaction, complications, and recurrent dislocation were recorded. The cohort consisted of both genders equally, and the mean age was 21.0±7.8 years, the mean body mass index was 22.5±3.5, and the mean follow-up time was 21.8±5.6 months. The patellar tiltdecreased from 46.4±19.3° to 12.5±16.9° (P < 0.001), the congruence angle decreased from 46.4±19.3° to 12.5±16.9° (P < 0.001), Kujala score improved from 55.1±4 to 88.7±4.4 (P < 0.001); Tegner score improved from 1.3±0.4 to 3.7±1.1 (P < 0.001), and Lyscholm score improved from 55.5±3.9 to 89.1±4.8 (P < 0.001). Among them, 30 (88.2%) patients fully recovered to normal pain-free daily life, 24 patients (70.6%) returned to sports, 32 patients were satisfied with surgery, and no redislocations were encountered. MPFL reconstruction via arthroscopy improves the knee joint function in patients with recurrent patellar dislocation and is a safe and effective surgical treatment for recurrent patellar dislocation.

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.

Flexible pes planovalgus is a common condition with flattening of the medial longitudinal arch accompanied by hindfoot valgus. Severe cases of pes planovalgus may need surgery, and a technique that has gained popularity over the past decades is subtalar arthroereisis. An endoorthotic implant of various shapes is inserted in the sinus tarsus, which limits the excessive eversion of the subtalar joint present in flexible pes planovalgus. None of these implants, however, allow for easy control of the extent of talocalcaneal and talonavicular correction. The primary aim of this study was to describe our technique with the custom-built cone-shaped implant. Our secondary aim was to evaluate patient satisfaction, clinical and radiologic results, and complications with a minimal follow-up of 5 years. Between January 1992 and June 2002, 40 patients (80 feet) underwent subtalar arthroereisis for flexible pes planovalgus. After temporary sinus tarsi tenderness (12 feet), implant dislocation (two feet) was the most common complication. Questionnaires from 27 patients (54 feet) were analyzed and 44 feet were also clinically and radiographically evaluated. Thirteen patients were lost to follow-up. Mean (± SD) follow-up was 12.6 years (range, 5.9–16.1). Eighty-one percent of the patients were satisfied with the result. Clinically, normal alignment was present in 14 feet, and mild deformities remained in 26 feet. Radiographically, the average foot angle measurements were normal. We conclude that subtalar arthroereisis is a simple, minimally invasive operative option with satisfactory subjective and clinical results after mid- to long-term follow-up.

Background: Biomechanical studies have shown that double-bundle (DB) posterior cruciate ligament reconstruction (PCLR) is better than single-bundle (SB) PCLR in restoring normal biomechanical function and stability. However, most clinical studies report no differences between the technical methods, and there is yet no long-term clinical comparative study. Hypothesis: DB PCLR would show superior results and survivorship outcomes to those of SB PCLR in long-term follow-up. Study Design: Cohort study; Level of evidence, 3. Methods: The authors retrospectively evaluated 64 patients who underwent primary PCLR between 2000 and 2008 and were followed up for a minimum of 10 years: 28 patients underwent SB PCLR (mean ± SD: age, 29.1 ± 12.2 years), and 36 underwent DB PCLR (age, 27.0 ± 9.2 years). Clinical scores (International Knee Documentation Committee subjective score, Lysholm score, Tegner activity score), side-to-side difference in stress radiographs, osteoarthritis progression, and survival rate were compared between the SB and DB groups at the last follow-up. Results: At the final follow-up, all clinical scores showed no significant differences between the SB and DB groups. The mean side-to-side difference in stress radiographs (SB, 5.3 ± 3.5 mm; DB, 5.0 ± 3.8 mm; P = .828) and osteoarthritis progression (SB, 14.3%; DB, 13.9%; P = .964) were not different between the groups. The 15-year survival rate was 82.1% for SB PCLR and 83.7% for DB PCLR. Conclusion: Both the SB and DB techniques for PCLR showed satisfactory long-term clinical results and survivorship outcomes. There were no significant differences between SB and DB PCLR in clinical, radiologic, and survivorship outcomes at a minimum follow-up of 10 years. Clinical Relevance: DB PCLR did not show superior clinical results to those of SB PCLR in the long-term follow-up. These results should be considered in the surgical planning for PCLR.

Background: We investigated the long-term clinical results of percutaneous transluminal angioplasty (PTA) in patients with peripheral arterial occlusive disease (PAOD) and the influence of different parameters on the primary success rate, the rate of complications and the long-term outcome. Patients and methods: We reviewed clinical and hemodynamic follow-up data of 166 consecutive patients treated with PTA in 1987 in our department. Results: PTA improved the clinical situation in 79.4% of patients with iliac lesions and in 88.3% of patients with femoro-popliteal lesions. The clinical stage and ankle brachial index (ABI) post-interventional could be improved significantly (each P < 0,001), the same results were observed at the end of follow-up (each P < 0,001). Major complications occurred in 11 patients (6.6%). The rate of primary clinical long-term success for suprainguinal lesions was 55% and 38% after 5 and 10 years (femoro-popliteal 44% and 33%), respectively, the corresponding data for secondary clinical long-term success were 63% and 56% (60% and 55%). Older age (P = 0,017) and lower ABI pre-interventional (P = 0,019) significantly deteriorated primary clinical long-term success for suprainguinal lesions, while no factor could be identified influencing the outcome of femoro-popliteal lesions significantly. Conclusion: Besides an acceptable success rate with a low rate of severe complications, our results demonstrate favourable long-term clinical results of PTA in patients with PAOD.

Background. Diverticulum, one of the long-term sequelae of cesarean section, can cause abnormal uterine bleeding and increase the risk of uterine scar rupture. In this study, we aimed to evaluate the efficacy of combined laparoscopic and hysteroscopic repair, a newly occurring method, treating post-cesarean section uterine scar diverticulum.Methods. Data relating to 40 patients with post-cesarean section uterine diverticulum who underwent combined laparoscopic and hysteroscopic repair were retrospectively analyzed. Preoperative clinical manifestations, size of uterine defects, thickness of the lower uterine segment (LUS), and duration of menstruation were compared with follow-up findings at 1, 3, and 6 months after surgery.Results. The average preoperative length and width of uterine diverticula and thickness of the lower uterine segment were recorded and analyzed. The average durations of menstruations at 1, 3, and 6 months after surgery were significantly shorter than the preoperative one (p<0.05), respectively. At 6 months after surgery, the overall success improvement rate of surgery was 90% (36/40). Three patients (3/40 = 7.5%) developed partial improvement, and 1/40 (2.5%) was lost to follow-up.Conclusions. Our findings showed that combined treatment with laparoscopy and hysteroscopy was an effective method for the repair of post-cesarean section uterine diverticulum.

Lost To Follow Up

Long-term surveillance of patients is necessary to ascertain the outcome of medical interventions. The rate of 'loss to follow-up' is the largest controllable variable in long-term follow-up studies. Such surveillance programmes are of particular importance to surgical interventions as differences between techniques or implants may take years to become apparent.
