Background: Whereas there has been growing interest in surgical repair of posterior medial meniscus root tears (PMMRTs), our understanding of the medium- and long-term results of this procedure is still evolving. Purpose: To report midterm clinical outcomes from PMMRT repairs. Study Design: Systematic review. Methods: A literature review for this systematic analysis was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We identified studies that reported the results of arthroscopic repair of PMMRTs. Functional and imaging outcomes were reviewed and summarized. Results: In total, 28 studies with a total of 994 patients (83% female) with an overall mean age of 57.1 were included in this review. Clinical outcomes (Lysholm, International Knee Documentation Committee, Hospital for Special Surgery, and Tegner scores) were improved at final follow-up in all studies. Of patients, 49% had radiographic progression of at least 1 grade in the Kellgren-Lawrence scale at a mean follow-up of 4.0 years in 11 studies. Cartilage degeneration had progressed at least 1 grade on magnetic resonance imaging scans in 23% of patients at a mean follow-up of 31.6 months in 4 studies. Conclusion: PMMRT repairs provide a functional benefit with consistent improvements in clinical outcome scores. There is some evidence that PMMRT repair slows the progression of osteoarthritis but does not prevent it at midterm follow-up.
Background: Anterior cruciate ligament (ACL) tears are common injuries; they are often associated with concomitant injuries to other structures in the knee, including bone bruises. While there is limited evidence that bone bruises are associated with slightly worse clinical outcomes, the implications of bone bruises for the articular cartilage and the risk of developing osteoarthritis (OA) in the knee are less clear. Recent studies suggest that the bone bruise pattern may be helpful in predicting the presence of meniscal ramp lesions. Evidence Acquisition: A literature review was performed in EMBASE using the keyword search phrase (acl OR (anterior AND cruciate AND ligament)) AND ((bone AND bruise) OR (bone AND contusion) OR (bone AND marrow AND edema) OR (bone AND marrow AND lesion) OR (subchondral AND edema)). Study Design: Clinical review. Level of Evidence: Level 4. Results: The literature search returned 93 articles of which 25 were ultimately included in this review. Most studies identified a high prevalence of bone bruises in the setting of acute ACL injury. Individual studies have found relationships between bone bruise volume and functional outcomes; however, these results were not supported by systematic review. Similarly, the literature has contradictory findings on the relationship between bone bruises and the progression of OA after ACL reconstruction. Investigations into concomitant injury found anterolateral ligament and meniscal ramp lesions to be associated with bone bruise presence on magnetic resonance imaging. Conclusion: Despite the ample literature identifying the prevalence of bone bruises in association with ACL injury, there is little evidence to correlate bone bruises to functional outcomes or progression of OA. Bone bruises may best be used as a marker for concomitant injury such as medial meniscal ramp lesions that are not always well visualized on magnetic resonance imaging. Further research is required to establish the longitudinal effects of bone bruises on ACL tear recovery. Strength of Recommendation Taxonomy: 2.
Category: Sports Introduction/Purpose: Peroneal tendon subluxation is an uncommon, yet well-known, condition that can occur after injury to the lateral ankle. The diagnosis can be difficult and is often missed or delayed. This may lead to recurrent or chronic subluxation or dislocation. Surgical management is often recommended, both in the acute and subacute setting. Multiple different surgical procedures have been described ranging from soft tissue repair to fibular groove deepening procedures. Soft tissue procedures alone may be inadequate to treat this pathology, especially in the case of shallow peroneal grooves. Multiple fibular groove deepening techniques have been described, although the population size in each study has been low. This investigation will evaluate the largest cohort of patients undergoing fibular groove deepening for peroneal subluxation or dislocation. Methods: Forty-four patients (Age 39.3 +/- 15.6, BMI 27.9 +/- 5.9) who underwent fibular groove deepening without concomitant bony procedures were able to return to clinic with a minimum two year follow-up. Demographic and operative data was collected via chart review. A standing CT scan, physical examination and functional outcome data was collected at the time of the office visit. The primary outcome was revision surgery. Secondary outcomes included radiographic findings(depth of groove), physical examination data (subluxation/dislocation, strength, ROM) and functional scores(FAAM). Results: 44 patients who underwent isolated peroneal groove deepening were enrolled. Rate of revision surgery was 3/44. CT scan showed an average depth on the operative side of (4.4 mm +/- 2.6) compared to (0.6 mm +/- 1.9) on the contralateral side. On physical exam 5% had objective subluxation, 2% dislocation, 84% had full strength to eversion. The median dorsiflexion and plantarflexion range of motion was 14 (0,100) and 40 (15,155) degrees, respectively. FAAM scores for ADL and Sports were (88.6% +/- 16.4% and 71.7% +/- 20.5%, respectively). 84% of patients would undergo the operation again. Conclusion: Our results show that peroneal groove deepening has a low recurrence rate but results in decreased strength and modest decreases in plantar flexion. The majority of patients were satisfied and would have the operation again. There was low incidence revision surgery (7%), and postoperative dislocation (2%). This is the first study to our knowledge that looked at postoperative CT scans. We showed that deepening is preserved and in our study increased peroneal groove depth by 3.8 mm on average.
Category: Hindfoot, Midfoot/Forefoot, Flatfoot Introduction/Purpose: Progression of flatfoot deformity and arthritis affects 6-38% of patients with posterior tibial tendon dysfunction treated with a triple arthrodesis. Current theory suggests that undercorrection of hindfoot valgus places abnormal stresses on the deltoid ligament and tibiotalar joint, contributing to the development of increased valgus tilt of the ankle joint or collapse of the medial arch. No large series to our knowledge has attempted to assess the potential benefit of the prospective correction of hindfoot valgus at the time of the triple fusion. Here we analyze the outcomes of 31 unilateral Stage III or IV rigid flatfoot corrections performed with concurrent medial displacement osteotomies. Methods: In an institutional review board approved retrospective study, a total of 31 feet in 31 patients were operated upon from 1/1/2009 to 1/1/2016 by a single surgeon at a large academic medical center. American Orthopaedic Foot & Ankle Society hindfoot scores and visual analog pain scores (VAS) were obtained prior to surgery and at the final post-operative follow-up where available). Foot and Ankle Ability Measure (FAAM) scores were available for 17 (54.8%) of patients. Patient demographic data, including age, body mass index (BMI), charlson comorbidity score, smoking status, and HbA1c where available were recorded. Additional surgical outcomes of interest included a return to unassisted mobility in a shoe or boot, infection and wound complication rate, 90 day re-admissions and revision/subsequent procedures. Pre-and post-operative data were analyzed using Student’s t-test for continuous variables, and Fisher’s exact test for categorical variables using Graphpad Prism (LaJolla, CA). Results: Patient demographic data is demonstrated in figure 1. Average follow-up was 1.3 ± 1.1 years (range .5 to 6.0 years). Average Pre-operative AOFAS scores available from 23/31 (74.2% of patients) averaged 33.5, with 1-year post-operative scores (8/31, 25.8%) of 76.8 ± 4.6 (p < .0001). VAS scores decreased from 6 ± 2.9 to 2 ± 2.7 (p < .0001). Superficial infections were treated in 3/31 (9.7%) of patients, while wounds developed in 6.5%. Mobility without assistive modality in a shoe or boot was reported by 30/31 (96.8%) patients, with one patient requiring a walker. No 90-day readmissions occurred, no amputations occurred, and a single patient returned to the OR 393 days after admission for symptomatic hardware removal. Conclusion: Here we demonstrate in a large retrospective analysis that performing a medial displacement osteotomy in patients with hindfoot valgus in the setting of rigid flatfoot deformity results in nearly universal remobilization, substantially improved functional outcomes, and significantly decreased pain. Few patients had wound complications or infections, and no revision reconstructions were required. Limitations to this study include inconsistent post-operative reporting, and a lack of long term post-operative outcomes. Further work incl...
