Introduction: Dislocation of patella is a very common injury which usually reduces spontaneously or can be reduced easily using gentle manipulation. Irreducible patellar dislocations are rare and usually result due to either rotation of patella along the horizontal or vertical axis or due to bony impaction. Neglected locked patellar dislocations are extremely rare injuries presenting additional challenges. Case Report: We are reporting a case of a 24-year female who presented to us 4 months after suffering a knee injury for which she received native treatment initially. On presentation, patient was able to walk with a limp and some discomfort but was unable to squat or sit cross-legged. Clinical examination revealed a patellar dislocation which was irreducible. On open reduction, the patella was found to be locked in the lateral gutter with rotation along its vertical axis and with an osteochondral fracture of its medial margin. There were a lot of fibrotic adhesions which required extensive release, following which the patella could be derotated and reduced into the trochlear groove. The medial retinaculum was repaired using transosseous sutures. Postoperatively, the patient developed wound edge necrosis which was managed with debridement and secondary suturing. At 1-year follow-up patient had almost full knee range of motion without any signs of patellar pain or instability and was able to squat and sit cross-legged. Conclusion: Unlike acute irreducible patellar dislocations which can be managed easily with open reduction, a neglected dislocation necessitates wider surgical exposure and a lot of soft tissue releases, which may jeopardize vascularity of the soft tissues leading to wound healing problems. Release of all adhesions while taking care to prevent further chondral injury, adequate lateral retinacular release, derotation of patella to relocate it into trochlear groove, and meticulous medial retinacular repair is essential for a successful outcome.

Aim. The aim of the study was to analyze the clinical results and MRI scans after transpatellar osteochondral fracture fixation following patellar dislocation. Methods. Our study group comprised 17 patients with patellar dislocation followed by osteochondral fracture of the articular surface of the patella. All patients underwent surgery where the fractured osteochondral fragments of the patella were attached using the transpatellar suture technique. The mean age at the time of surgery was 14.1 years, and the mean follow-up period was 7.5 years. Results. The results of the patellar compression test and the apprehension test were negative in all patients. The mean Lysholm and Kujala scores were 89.2 and 89.6, respectively. The MRI scan revealed healing of the fixed fragment and restoration of the articular surface in all patients. In 16 cases, subchondral bone of the fixed fragment area was described as irregular: its articular cartilage was narrowed and not homogenous. Progressive degenerative changes were observed in the patellofemoral joint at follow-up in three patients. Conclusions. By fixing osteochondral fragments, the patellar articular surface can be restored. The MRI scans show that the cartilage in the reconstructed surface is narrowed after a mean 7.5-year follow-up.

Introduction Deep brain stimulation (DBS) of the posterior hypothalamus (pHyp) has been reported as an effective treatment for primary, drug-refractory and chronic cluster headache (CCH). We here describe the use of such a procedure for the treatment of secondary CCH due to a neoplasm affecting the soft tissues of the right hemiface. Methods A 27-year-old man affected by infiltrating angiomyolipoma of the right hemiface who subsequently developed drug refractory homolateral CCH underwent DBS of the right pHyp region at the Fondazione IRCCS Istituto Nazionale Neurologico Carlo Besta. Results After surgery, the patient presented a significant reduction in frequency of pain bouts. However, because of a subsequent infection, the entire system was removed. After re-implantation of the system, successful outcome was observed at 2 years follow-up. Discussion This brief report shows the feasibility of pHyp DBS in secondary drug-refractory CCH syndromes; future reports are needed in order to confirm our positive result.

Developmental dysplasia of hip (DDH) represents a spectrum of disorders in which the femoral head has an abnormal relationship to the acetabulum. Management of DDH presenting in walking stage are primarily surgical because of changes in femoral head, acetabulum and soft tissues around joint. We looked at the incidence of AVN during midterm follow up period in DDH patients in the walking age group who had undergone single stage surgery. Also it evaluates association of different variables with occurrence of AVN. The AVN of head of femur is assessed according to Kalamchi and MacEwen’s classification and AVN gradings were compared with different surgical procedures. In our study, higher incidence of AVN was seen patients who were operated at a higher age, who had higher preoperative Tonnis grading and those who required osteotomies with open reduction. But statistically significant correlation could not be established independently with any of the above mentioned variables.

Background: Closing-wedge distal femoral osteotomy (CWDFO)—combined with medial reefing and lateral release, if necessary— has been used to treat recurrent patellar dislocation (RPD) with genu valgum. Purpose: To evaluate the clinical and radiologic outcomes of surgical treatment with CWDFO for treatment of RPD with genu valgum. Study Design: Case series; Level of evidence, 4. Methods: Fourteen consecutive patients (23 knees) with RPD and genu valgum were treated with CWDFO. Patients with a minimum 2-year follow-up period were eligible for this study. Patients with prior failed surgery were also eligible. Radiographic evaluation was performed with mechanical femorotibial and lateral distal femoral angle. The radiographic parameters presenting patellar positions and pathologic abnormalities associated with RPD were evaluated. Chondral lesion changes in second-look arthroscopic examination were examined, and clinical outcomes (eg, occurrence of redislocation, range of motion, and clinical scores) were assessed pre- and postoperatively at a minimum of 2 years. Results: At a mean follow-up of 30.7 months (range, 25-62 months), the mean mechanical femorotibial and mechanical lateral distal femoral angles changed significantly from valgus 5° (range, 2°-11°) to varus 3° (2°-11°; P < .001) and from 83° (range, 78°-86°) to 89° (84°-92°; P < .001), respectively. The mean patellar congruence angle improved from 40° lateral (range, 20°-53° lateral) to 4° medial (23° medial to 21° lateral; P < .001), as did the lateral patellofemoral angle from 26° (range, 8°-62°) to 9° (0°-15°; P < .001). Computed tomography scans showed that the mean distance of patellar lateral shift decreased from 13.5 mm (range, 4-22 mm) to 2.0 mm (–4 to 5 mm; P < .001). The mean tibial tubercle to trochlear groove distance significantly decreased from 20.4 to 13.5 mm ( P < .001), while the Caton-Deschamps ratio did not change significantly after surgery ( P = .984). Chondral lesions of the patella and trochlear groove significantly improved or were maintained. None of the patients experienced subluxation or redislocation after surgery. Patellar instability symptoms also improved, as validated by radiographic and other clinical outcomes. Conclusion: CWDFO combined with medial reefing and lateral release successfully treated RPD with genu valgum for a minimum follow-up of 2 years, with improved patellar alignment and stability.

BackgroundWe describe a minimally open reduction and percutaneous fixation technique for three- and four-part proximal humeral fracture–dislocations which preserves soft tissues.MethodsEleven consecutive patients with three-and four-part proximal humeral fracture–dislocations (eight anterior, three posterior dislocations) were treated this way. The dislocation is reduced using a mini-open deltopectoral approach with a horizontal split in subscapularis. Fracture fragments are fixed with percutaneous screws. Constant and Oxford Shoulder Score were collected prospectively.ResultsMean age was 51 years (range 32–65). Mean follow-up was 36 months (range 24–72 months). At last follow-up mean Constant score was 75 (range 64–86) compared to 88 (range 85–92) for the uninjured shoulder. Mean Oxford shoulder score was 41 (range 34–46). One patient developed avascular necrosis. Screw back out was seen in three patients. These were removed under local anaesthesia. There were no screw penetrations of articular surface. One patient suffered a radial nerve neuropraxia which resolved.ConclusionThese results are promising and comparable to published literature with other means of fixation for this complex problem. Due to minimal soft tissue dissection the complications rate is low.

Chondral Injury

AbstractChondral injury is a serious consequence of patellar dislocation and patellofemoral instability (PFI). There is limited data on the relationship between radiological features such as sulcus angle and patellar height to the presence, location, and severity of chondral lesions. The purpose of this study was to determine the association of anatomical variants in patellofemoral instability with injuries sustained due to patellar dislocation. A cohort of 101 patients who had four or more episodes of dislocation or instability undergoing isolated arthroscopy or arthroscopies at the time of corrective realignment surgery were identified. The prevalence of chondral, ligamentous, and meniscal injuries was determined and correlated to the sulcus angle, tibial tubercle trochlear groove distance, and patellar height on magnetic resonance imaging (MRI) scans. A total of 101 patients was identified. At arthroscopy, the patella demonstrated the highest incidence of chondral injury (68%) followed by the trochlear groove (40%). Lateral meniscal injuries were noted in 6% of patients, medial meniscal injuries in 2%, and anterior cruciate ligament (ACL) injury in 3%. Chondral injuries were graded using the Outerbridge criteria and there was a correlation between more severe chondral injuries and a greater tilt angle (p = 0.05). The occurrence of injury to the lateral meniscus was associated with a higher Insall–Salvati ratio (p = 0.05). More severe chondral injuries are seen in patients with a greater tilt angle.

Aims The aim of this study was to investigate the changes in femoral trochlear morphology following surgical correction of recurrent patellar dislocation associated with trochlear dysplasia in children. Patients and Methods A total of 23 patients with a mean age of 9.6 years (7 to 11) were included All had bilateral recurrent patellar dislocation associated with femoral trochlear dysplasia. The knee with traumatic dislocation at the time of presentation or that had dislocated most frequently was treated with medial patellar retinacular plasty (Group S). The contralateral knee served as a control and was treated conservatively (Group C). All patients were treated between October 2008 and August 2013. The mean follow-up was 48.7 months (43 to 56). Axial CT scans were undertaken in all patients to assess the trochlear morphological characteristics on a particular axial image which was established at the point with the greatest epicondylar width based on measurements preoperatively and at the final follow-up. Results Preoperatively, there were no statistically significant differences between the trochlear morphology in the two groups (sulcus angle, p 0.852; trochlear groove depth, p 0.885; lateral trochlear inclination, p 0.676; lateral-to-medial facet ratio, p 0.468; lateral condylar height, p 0.899; medial condylar height, p 0.816). Many radiological parameters of trochlear morphology were significantly different between the two groups at the final follow-up, including well-known parameters, such as the mean sulcus angle (Group S, 146.27° (sd 7.18); Group C, 160.61° (sd 9.29); p < 0.001), the mean trochlear groove depth (Group S, 6.25 mm (sd 0.41); Group C, 3.48 mm (sd 0.65); p < 0.001) and the mean lateral trochlear inclination (Group S, 20.99° (sd 3.87); Group C, 12.18° (sd 1.85); p < 0.001). Lesser known parameters such as the ratio of the lateral to medial trochlear length (Group S, 1.46 (sd 0.19); Group C, 2.14 (sd 0.42); p < 0.001), which is a measurement of facet asymmetry, and the lateral and medial condylar height were also significantly different between the two groups (p < 0.001). Conclusion The femoral trochlear morphology can be improved by early (before epiphyseal closure) surgical correction in children with recurrent patellar dislocation associated with femoral trochlear dysplasia.

Background: Patients who are refractory to initial management of trochlear dysplasia, which consists of bracing and physical therapy, may be candidates for trochleoplasty. Indications: Indications for trochleoplasty include Dejour classification type B or D trochlear dysplasia, supratrochlear spur height ≥7 mm, and a positive J sign on examination. Technique Description: The thick shell sulcus-deepening trochleoplasty technique involves removing the supratrochlear spur by creating a 5-mm–thick osteochondral shell with underlying cavity, dividing the thick shell into medial and lateral leaflets, and securing the leaflets with absorbable sutures. This establishes a new trochlear groove that is flush with the anterior cortex of the femur. Results: A review of 21 studies with length of follow-up from 8.8 months to 15 years found postoperative dislocation was present in 0% to 15% of patients and the patient satisfaction ranged from 81.0% to 94.4%. A prospective study with a minimum 2-year follow-up found no cases of recurrent dislocation, no progression of radiographic arthritis, 84.8% of patients returned to sport, and the patient satisfaction was a 9.1/10. Discussion/Conclusion: Sulcus-deepening trochleoplasty for trochlear dysplasia provides patellar stability and excellent patient satisfaction.

Abstract Purpose The main purpose of this study was to determine whether there is a correlation between the change of tibial tuberosity-trochlear groove (TT-TG) distance and clinical outcomes after total knee arthroplasty (TKA). Methods A total of 52 knees undergoing TKA due to primary osteoarthritis were included in this retrospective study. All patients had pre- and postoperative CT scans. TT-TG distance was measured by two independent observers and the following alignment parameters were measured: hip-knee ankle angle (HKA), femoral mechanical angle (FMA), tibial mechanical angle (TMA), and posterior condylar angle (PCA). Clinical outcome was assessed using Knee Society Score (KSS) pre- and post-operatively and at a minimum of 12-month follow-up. Evidence of AKP was noted from follow-up reports. Pre- and postoperative scores were compared using a paired Student t-test. Pearson correlations were calculated to assess the influence of TT-TG on clinical outcome and of alignment parameters on the change in TT-TG. TT-TG between patients with and without AKP was compared using unpaired Student’s t-test (p < 0.05). Results Neither the absolute postoperative TT-TG nor the amount of change in TT-TG correlated with the post-operative KSS or the change in KSS. Post-operative TT-TG and change in TT-TG did not differ significantly between patients with and patients without AKP. Only the change in FMA showed a correlation with the change in TT-TG (p = 0.01, r = 0.36). Conclusion Despite a missing correlation between outcomes and TT-TG distance in this study, excessive TT-TG distance should be avoided. Furthermore, surgeons need to be aware that changes in femoral joint line orientation might affect TT-TG distance.
