Lateral retinacular release

Nick Caplan, Islam Nassar, Bobby Anand, Deiary F Kader
In recent years, surgical interventions for patellofemoral joint instability have gained popularity, possibly revitalized by the recent advances in our understanding of patellofemoral joint instability and the introduction of a number of new surgical procedures. This rise in surgical intervention has brought about various complications. In this review article, we present the complications that are associated with 5 main surgical procedures to stabilize the patella-medial patellofemoral ligament reconstruction, tibial tubercle osteotomy, trochleoplasty, lateral release/lateral retinacular lengthening, and derotation osteotomies...

INTRODUCTION: Locked vertical patellar dislocations are rare and pose a therapeutic challenge. This case is more unusual, as the patient was a known case of recurrent patellar dislocation and presented with an atraumatic locked and vertically rotated patellar dislocation. This type of presentation has never been reported in literature to the best of our knowledge. CASE PRESENTATION: A 14-year-old healthy male child with previous history of recurrent lateral dislocation of patella presented to accident & emergency department with complaints of inability to walk or bear weight on his left lower limb after he spontaneously dislocated his patella while running on uneven ground...

To evaluate whether arthroscopic lateral retinacular release and the modified Elmslie-Trillat operation improve osteoarthritis (OA) progression and clinical outcomes in patients with severe isolated lateral patello-femoral OA. Nine women (11 knees) and one man (one knee) with isolated late-stage lateral patello-femoral OA underwent surgery. The severity of patello-femoral OA was recorded using the Merchant method, while the level of pain and anterior knee function were scored using the visual analogue scale (VAS) and Kujala knee scores, respectively...

AIM: To study patient outcomes after surgical correction for iatrogenic patellar instability. METHODS: This retrospective study looked at 17 patients (19 knees) suffering from disabling medial patellar instability following lateral release surgery. All patients underwent lateral patellofemoral ligament (LPFL) reconstruction by a single surgeon. Assessments in all 19 cases included functional outcome scores, range of motion, and assessment for the presence of apprehension sign of the patella to determine if LPFL reconstruction surgery was successful at restoring patellofemoral stability...

BACKGROUND: Incongruity of the patellofemoral joint after total knee arthroplasty (TKA) causes anterior knee pain. Intraoperative congruity tests are necessary to avoid unnecessary lateral retinacular release, and the usage of tourniquets may influence these results. The purpose of this study was to examine the effect of tourniquets on patellofemoral joint congruity during TKA. MATERIALS AND METHODS: Two hundreds and seventeen knees were examined after TKA. Skyline radiographs at 60° and 90° flexion were taken immediately after wound closure before and after tourniquet deflation to compare changes in patellar tilt angle...

OBJECTIVE: To describe a novel coronal osteotomy of the external facet of the patella, and to evaluate if the outcomes of the treatment of lateral knee compartment syndrome (LKCS) with this osteotomy, combined with the release of the external lateral retinaculum, are better than the isolated lateral retinacular release. MATERIAL AND METHODS: A prospective study with a 2 year follow up that included 70 patients diagnosed with LKCS, distributed into 2 groups. The first group included 50 patients on whom the lateral retinacular release combined with osteotomy was performed, and a second group on whom an isolated retinacular release was performed...

BACKGROUND: The main objective of this prospective randomized study was to compare the clinical and radiographic outcomes of the mini-midvastus (MMV) approach with the conventional approach for total knee arthroplasty at the 5-year follow-up. METHODS: Ninety-seven patients (100 knees) with osteoarthritis were assigned to the MMV group or to a group receiving conventional total knee arthroplasty. Intraoperative and postoperative clinical data were collected. At 6 weeks and at 1, 2, and 5 years postoperatively, the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Oxford Knee Score (OKS), the Knee Society Score (KSS), and the Short Form (SF)-12 were completed...

Objectives Anterior knee pain (AKP) is integral to the overall success of total knee arthroplasty (TKA) without patellar resurfacing. Numerous studies have evaluated various factors that may contribute to AKP, including patellofemoral design, surgical technique, characteristics of the patient, and degree of chondromalacia. This study aims to explore whether patients who received lateral retinacular release (LRR) plus circumpatellar electrocautery (CE) in TKA attain a low incidence of AKP and whether the LRR plus CE increases postoperative complications...

BACKGROUND: Lateral retinacular release has been demonstrated to reduce articular patellofemoral pressures, while intra-articular injection of hyaluronic acid can improve the biological and rheological knee pathway. We evaluated whether treatment protocol consisting on combination of these two therapies can provide significant symptomatic improvement in patients with patellofemoral osteoarthritis (PFO) and patellar tilt. MATERIALS AND METHODS: We retrospectively analyzed the clinical and radiological data of 28 knees (25 patients with anterior knee pain) who underwent arthroscopic lateral retinacular release followed by viscosupplementation for isolated patellofemoral osteoarthritis without clinical or radiological signs of patellar instability...

BACKGROUND: Bone tunneling and implants with rigid fixations for medial patellofemoral ligament (MPFL) reconstruction are known to compromise results and are avoidable, especially in skeletally immature subjects. This study was to assess if these deficiencies were overcome with the technique devised by the author which avoids implants and bone tunnels. Results were assessed for complication rate and outcome. MATERIALS AND METHODS: Fifty six knees of recurrent lateral patellar dislocation were treated in the past 49 months by MPFL reconstruction...

Transient patellar dislocation is a common entity in children and adolescents, characterized by lateral dislocation of the patella, usually with spontaneous reduction. Many predisposing conditions have been described, including trochlear dysplasia, excessive lateral patellar tilt, patella alta and lateralization of the tibial tuberosity. Associated injuries are bone bruises of the patella and lateral femoral condyle, tears of the medial retinaculum that include the medial patellofemoral ligament (MPFL), tears of the vastus medialis obliquus muscle, injuries of articular cartilage, and intra-articular bodies...

BACKGROUND: Kinematic alignment for total knee arthroplasty (TKA) may be one way of improving outcomes. Previous studies have either used patient-specific instrumentation, which adds cost, or standard instrumentation, which provides no intraoperative feedback on resection alignment. HYPOTHESIS: To determine if computer navigation could reproduce native patient anatomy and simplify ligament balance during TKA whilst giving satisfactory improvements in functional scores at early follow-up...

Medial patellar subluxation is a poorly recognized clinical condition characterized by chronic anterior knee pain that is exacerbated with knee flexion. Additional symptoms include instability, limited knee motion, and pain with squatting and stair climbing. Full characterization of the patient's knee pain requires an accurate history and physical examination. Diagnosis is typically confirmed during diagnostic arthroscopy. When nonsurgical management (eg, physical rehabilitation, patella-stabilizing bracing) fails, surgery (eg, medial retinacular release, lateral retinacular imbrication, newer techniques to repair or reconstruct the lateral retinaculum/lateral patellofemoral ligament) can lead to good results...

BACKGROUND: The quadriceps-sparing and subvastus approaches are two of the most commonly used minimally-invasive approaches in total knee arthroplasty (TKA). However, the conclusion among studies still remains controversial. The purpose of this meta-analysis was to compare the clinical efficacy of the subvastus and quadriceps-sparing approaches with the standard parapatellar approach in TKA. METHODS: Randomized controlled trials (RCTs) comparing the quadriceps-sparing or subvastus approach with the standard parapatellar approach was identified in the databases of PubMed, the Cochrane library, EMBASE and Web of Science up to July 2014...

Medial patella subluxation is a disabling condition typically associated with previous patellofemoral instability surgery. Patients often describe achy pain with painful popping episodes. They often report that the patella shifts laterally, which occurs as the medial subluxed patella dramatically shifts into the trochlear groove during early knee flexion. Physical examination is diagnostic with a positive medial subluxation test. Nonoperative treatment, such as focused physical therapy and patellofemoral stabilizing brace, is often unsuccessful...

BACKGROUND: The medial patellofemoral ligament (MPFL) has been implicated as a common pain generator in adolescents with anterior knee pain. The purpose of this study is to report the clinical outcomes of arthroscopic lateral retinacular release (ALRR) for refractory MPFL-centered pain and to identify risk factors for poor outcomes and surgical failures. METHODS: A single-surgeon database was queried to identify all patients undergoing ALRR. Inclusion criteria included minimum 12-month follow-up and ALRR performed for MPFL pain rather than for generalized anterior knee pain or patellar instability...
