Medial patellofemoral ligament physical therapy

Eric Hohn, Nirav K Pandya
BACKGROUND: Medial patellofemoral ligament (MPFL) reconstruction is one of several surgical procedures used to treat patellofemoral instability. Use of allograft tissue can preserve autogenous tissue and may be preferable in patients with connective tissue disorders or ligamentous laxity. Although there are successful reports in adults, it is unclear if the use of allograft tissue in MPFL reconstruction can restore patellofemoral stability in children and adolescents. QUESTIONS/PURPOSES: (1) Does allograft tissue in MPFL reconstruction in pediatric and adolescent patients restore patellar stability? (2) What complications were associated with allograft MPFL reconstructions in children and adolescents? METHODS: Between June 2012 and August 2015, one surgeon (NKP) performed 26 MPFL reconstructions in 23 patients with gracilis allograft for traumatic patellar instability...

BACKGROUND: The incidence of patellar subluxation or dislocation has been documented up to 43/100,000 with females more prevalent then males. There are many contributing factors involving the hip, knee, and ankle that lead to patellar subluxation. A patellar position of lateral tilt with lateral glide may indicate weakness of the vastus medialis oblique (VMO) and adductors, increased tightness in the iliotibial band, and overpowering of the vastus lateralis. Patella alta can predispose an individual to lateral dislocation due to the patella placement outside of the femoral trochlear groove with a disadvantage of boney stability...

Acute patellar dislocations are a common injury occurring in adolescents involved in sports and dancing activities. This injury usually occurs when the knee is in full extension and sustains a valgus stress on the knee. The medial patellofemoral ligament is the medial restraint that assists in stabilizing the patella from lateral dislocations. The patella usually dislocates laterally and is usually not difficult to reduce after patient evaluation and prereduction radiographs. After postreduction radiographs confirm proper position of the patella postreduction and the absence of fractures, the patient is usually treated conservatively with initial immobilization, orthopedic referral, and physical therapy...

Patellofemoral instability is a common problem in the adolescent population. Patellar stability depends on a dynamic interplay between bony and soft tissue restraints. Several pathoanatomical factors increase the likelihood of patellar instability: patella alta, trochlear dysplasia, malalignment, and deficient proximal medial restraints. Treatment for first-time patella dislocations is typically nonoperative and includes bracing, early range of motion, and physical therapy. The only absolute indication for early surgery is a large osteochondral fragment that can be fixed...

BACKGROUND: Patellar dislocations are traumatic injuries that occur most often in individuals under the age of twenty and are related to sports and physical activity. Currently, there are no published reports describing the rehabilitation of younger males after arthroscopy and open reconstruction of the medial patellofemoral ligament (MPFL) using a tibialis anterior allograft. CASE DESCRIPTION: The subject of this case report was a 23 year-old recreational male athlete who underwent right knee arthroscopic patellar chondroplasty, lateral retinacular release, partial lateral menisectomy, and an open MPFL reconstruction with a tibialis anterior allograft after sustaining a second patellar dislocation...

Patellar instability is a common complaint after traumatic dislocation of the patella. Traumatic dislocation always leads to tearing of the medial patellofemoral ligament (MPFL). Treatment consists of recovery from the traumatic injury, followed by reconditioning and physical therapy to strengthen the dynamic stabilizers of the patella. In patients with recurrent instability, detailed evaluation of the cause is required to determine the needed interventions. In patients with an incompetent MPFL and recurrent instability, reconstruction is indicated, along with other procedures to address other contributing factors...

BACKGROUND: Recurrent lateral patellar dislocation is a common knee injury in the skeletally immature adolescent. Because of the open physis, operative therapy in children is challenging. This study presents the outcomes of a minimally invasive technique for anatomic reconstruction of the medial patellofemoral ligament (MPFL) in children that respects the distal femoral physis. HYPOTHESIS: Anatomic reconstruction of the MPFL in children that maintains the distal femoral physis will prevent redislocation, preserve the distal femoral physis, and improve knee function...

Patellar instability is a complex topic that must be treated at the individual level. The majority of first-time patellar dislocations occur in sport, and there is a high rate of recurrence and ongoing symptoms. Physical examination and imaging studies can aid in treatment decisions. Patient symptoms, degree of trauma, compliance with therapy, anatomical factors, and desired activity levels influence management strategies (both operative and nonoperative). There is recent emphasis on the medial patellofemoral ligament and its involvement in patellar stability, and various surgical techniques have been studied; however there is no clear consensus...

The standard approach to reconstruct the medial patellofemoral ligament (MPFL) is by mini-open incision at its patellar insertion and femoral origin. At the medial patella rim, the MPFL insertion may be visualized in most cases by dissection during surgery. On the femur, it is more difficult to localize the MPFL remnants by a mini-open incision due to soft tissue covering the anatomical origin. Therefore, the femoral MPFL origin is usually identified by intraoperative lateral fluoroscopy. However, the insertion and origin of the MPFL at the patella and femur might be directly visualized using an arthroscopic extraarticular approach from the knee joint through a window of the synovial layer...

INTRODUCTION: Medial patellar subluxation is usually seen after lateral retinacular release. Spontaneous medial subluxation of the patella is a very rare condition. There are few reports in the literature on the pathophysiology of iatrogenic medial patellar subluxation. To our knowledge, there are no reports of the pathophysiology of non-iatrogenic medial patellar subluxation in the English literature. In this study we present a case of spontaneous medial patellar instability that is more prominent in extension during weight bearing...

STUDY DESIGN: Resident's case problem. BACKGROUND: Kaposi's sarcoma (KS) is the most common form of cancer in patients with human immunodeficiency virus (HIV) infection. Although KS is often initially asymptomatic, this neoplasm may progress to affect multiple organ systems, including structures of the musculoskeletal system, which can produce symptoms similar to those associated with common orthopaedic conditions. This resident's case problem describes the evaluation and differential diagnosis of a 45-year-old male with HIV and KS, referred to physical therapy with an initial diagnosis of radiographic osteoarthritis (OA) and patellofemoral pain syndrome (PFPS) of the left knee...

PURPOSE: The objective of this study was to analyze and compare the results obtained after 2 types of treatment, surgical and conservative, for acute patellar dislocations. METHODS: We divided 33 patients with acute patellar dislocations into 2 groups. One group with 16 patients underwent conservative treatment (immobilization and subsequent physiotherapy), and the other group with 17 patients underwent surgical treatment. A radiographic examination was performed in the evaluation of the patients to verify predisposing factors for patellofemoral instability, and the Kujala questionnaire was applied with the intention of analyzing the improvement of pain and quality of life...

Recurrent patellar instability can result from osseous abnormalities, such as patella alta, a distance of >20 mm between the tibial tubercle and the trochlear groove, and trochlear dysplasia, or it can result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament or a weakened vastus medialis obliquus. Nonoperative treatment includes physical therapy, focusing on strengthening of the gluteal muscles and the vastus medialis obliquus, and patellar taping or bracing. Acute medial-sided repair may be indicated when there is an osteochondral fracture fragment or a retinacular injury...

PURPOSE: The purpose of this study was to evaluate the mid-term results of the Elmslie-Trillat procedure for the treatment of patella instability. Patella instability can be addressed by proximal, distal, and combined approaches. The Elmslie-Trillat procedure is a combined bony distal realignment with medial soft tissue technique offering a more rapid recovery than more extensive distal realignments. METHODS: A consecutive series of patients with recurrent patellar instability treated with a modified Elmslie-Trillat procedure were assessed subjectively by visual analog scale, Tegner scale, and both pre-and postoperatively by physical examination, International Knee Documentation Committee activity, Lysholm, and Fulkerson knee scores...

We describe the case of a 14-year-old boy with patellar instability on both sides resulting from ligamentous hyperlaxity and dysplasia of the lateral femoral condyle who had previously undergone an arthroscopic lateral release as well as plication of the medial capsule. The patient presented to our clinic 2 years after surgery with a locked lateral patella dislocation on the left side. The surgical correction involved a substantial open lateral release including an excision of the scar tissue and stabilization of the patella in the patellofemoral groove by tibial tubercle medialization and plication of the medial capsule...
