ABSTRACT

BACKGROUND: Patellar tendinopathy (PT) involves anterior knee pain and functional. Platelet-rich fibrin matrix (PRFM) is a promising biological therapy for tendinopathies. We examined a cohort of PT patients treated with tendon debridement and autologous PRFM at the 24-month follow-up to assess whether the combined treatment facilitated return to sports and yielded satisfactory clinical and functional scores. METHODS: Baseline and 24-month visual analogue scale (VAS), Victorian Institute of Sport Assessment Scale for Patellar Tendinopathy (VISA-P), Tegner Activity Scale (TAS), and Blazina scores were compared to evaluate treatment effectiveness. The Friedman test was used to compare repeated observations of VAS, VISA-P, TAS, and Blazina Score values. Return to sport rate, Tampa Scale of Kinesiophobia (TKS) score and patient satisfaction were collected at 24 months. RESULTS: The postoperative clinical scores demonstrated significant improvement compared with their preoperative values (all p < 0.001). Specifically, the VISA-P score was 80.32 (±20.58), 92.10% of patients had resumed sports activities and patient satisfaction was 9.21 (±1.21) at 24 months. CONCLUSIONS: Surgical debridement and autologous PRFM application in patients with chronic PT resulted in a higher rate of return to sports when compared to solely surgical treatment, significantly improved clinical outcomes and excellent patient satisfaction at 24 months.

ABSTRACT

BACKGROUND: Glenohumeral osteoarthritis (GOA) is associated with disabling shoulder pain that affects everyday life. Its management comprises various treatment approaches, both conservative and surgical. Regenerative medicine has gained a major role in the conservative treatment of osteoarthritis. Intra-articular injection of adipose-derived mesenchymal stem cells (ADMSCs) is a widely used regenerative medicine approach. The aim of this retrospective study was to report the safety and clinical outcomes of intra-articular injection of ADMSCs in patients with GOA over 36-months. METHODS: This retrospective observational study involved patients with chronic shoulder pain resistant to standard conservative treatment and a diagnosis of concentric GOA, who received an intra-articular injection of autologous micro-fragmented adipose tissue (µFAT). The values of the Constant-Murley score (CMS), the visual analog scale (VAS), and the simple shoulder test (SST), collected at baseline and at 12, 24, and 36 months, were analyzed to assess treatment efficacy. The single assessment numeric evaluation (SANE) was used to rate patient satisfaction. The Friedman test was used to compare observations of CMS, VAS, and SST values repeated on the same subjects. The significance threshold was set at 0.05. RESULTS: The participants were 65 patients with a mean age of 54.19 years and a nearly equal gender distribution. Most had mild concentric GOA classified as Samilson-Prieto grade 1. The mean follow-up duration was 44.25 months. The postoperative clinical scores showed significant improvement. At 36 months, the CMS was 84.60, the VAS score was 3.34, and the SST score was 10.15 (all p < 0.0001). The SANE score at 36 months indicated that 54 patients (83.08%) were completely satisfied with the treatment. CONCLUSION: ADMSC treatment exerted favorable effects on the clinical outcomes of patients with GOA, providing pain relief and improving shoulder function. Our data support its use as a conservative treatment option for osteoarthritis.

ABSTRACT

(1) Background: Achilles tendinopathy (AT) is characterized by load-induced tendon pain, stiffness, and functional impairment that may affect the tendon midportion or insertion. Platelet-rich fibrin matrix (PRFM) is a promising adjunctive therapy for AT. We analyzed 24-month pain and functional outcomes in a cohort of patients managed by tendon debridement and autologous PRFM application to determine whether the combined treatment ensured an early return to sports/work and satisfactory clinical outcomes and functional scores. (2) Methods: The 24-month outcomes of 32 sport-practicing patients with chronic midportion AT treated with debridement and autologous PRFM were evaluated in terms of time to return to sports/work. The AOFAS and VISA-A were computed preoperatively and at 6 and 24 months. Blazina scores were evaluated preoperatively and at 6 months; ankle range of motion was assessed at 1, 6, 12, 24 months; and patient satisfaction was assessed at 24 months. (3) Results: Altogether, all patients had resumed their sport(s) activity, at the same or higher level, after 25.41 days (±5.37). Regarding work, all patients were able to return to their jobs after 16.41 days (±2.43). Ankle dorsiflexion and plantarflexion increased significantly: the AOFAS rose from 54.56 (±6.47) to 97.06 (±4.06) and 98.88 (±2.21) at 6 and 12 months, respectively, and the mean VISA-A score rose from 69.16 (±7.35) preoperatively to 95.03 (±4.67) and 97.28 (±2.43) at 6 and 12 months, respectively, after treatment. There were no complications. Most (90.62%) patients were very satisfied. (4) Conclusions: In symptomatic midportion AT, surgical debridement and autologous PRFM ensured a fast return to sports/work (4 weeks), significantly improving AOFAS and VISA-A and Blazina scores already at 6 months and providing excellent clinical outcomes at 24 months.

ABSTRACT

OBJECTIVE: High tibial valgus osteotomy (HTO) is a widely accepted procedure indicated for varus knee with symptomatic osteoarthritis of the medial compartment. However, there is a lack of studies evaluating long term results of this procedure. The primary aim of this study was to evaluate the long-term survival of opening wedge high tibial osteotomy (HTO) for isolated osteoarthritis in the medial compartment of the knee. The secondary objective was to identify independent predictors of conversion to total knee arthroplasty (TKA). METHODS: This is a long term retrospective study of 296 cases of open wedge HTOs performed at a single center (level of evidence IV) between January 2005 and August 2015. Opening wedge medial HTO was always performed after diagnostic arthroscopy. Eighty-three percent of the population (233 patients, 247 procedures) was followed up at a mean 11.6 years (6-17) by telephone interview, to evaluate the possible conversion to TKA. Mean age at the index operation was 42.8 years (range 15-70) and most patients were male (70%). Associated procedures (e.g., platelet rich plasma supplementation, microfractures, meniscectomy, etc.) were carried out at the time of the HTO in 80 (32%) cases. Survival of HTO and its association with age, sex, body mass index, smoking habit, preoperative severity of varus deformity, cartilage status at surgery, and associated procedures were evaluated. Kaplan-Meier and Cox regression analyses were performed. RESULTS: Thirty-three of the 247 HTOs (13.4%) were converted to knee replacement, with 86.6% of the original procedures surviving at a mean 12-year follow-up. Kaplan-Meier survival estimates at 17 years for HTO were 75.5% (95% confidence interval [CI] 66.7-84.3). There was significant difference (P < 0.001) in the 17-year survival rate between obese (55.5%; 95% CI 35.3-75.6) and non-obese (79.7%; 95% CI 70.1-89.2) patients. The determinants of conversion to knee arthroplasty detected at multivariate Cox regression analysis were body mass index, severity of cartilage degeneration in the medial compartment (Outerbridge grade), and age. CONCLUSION: The long-term survival of open wedge HTO for osteoarthritis in the medial compartment of the knee is satisfactory. The risk of conversion to TKA is significantly increased in obese patients. Advanced age and severity of pre-existing cartilage damage may also contribute to the risk of conversion to TKA.

ABSTRACT

Background Dual-energy CT (DECT) is an alternative to radiography and single-energy CT (SECT) for detecting prosthesis-related complications. Purpose To compare the diagnostic performance of DECT, SECT, and radiography for knee prosthesis loosening, with use of surgery or imaging follow-up reference standards. Materials and Methods In this prospective single-center study from December 2018 to June 2021, participants with unilateral painful knee prostheses underwent radiographic, SECT, and DECT imaging. Five blinded readers, four radiologists, and one orthopedic surgeon evaluated the images. Prosthesis loosening was diagnosed by a periprosthetic lucent zone greater than 2 mm. The sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) of each method were determined and compared with use of a multireader multicase analysis. Results There were 92 study participants (mean age ± SD, 70 years ± 9.4; 67 women) evaluated. Tibial and femoral loosening were diagnosed in 47 and 24 participants, respectively. For the tibia, mean sensitivity and specificity for arthroplasty loosening were 88% and 91%, respectively, for DECT, 73% and 78% for SECT, and 68% and 81% for radiography. For the tibia, DECT demonstrated similar diagnostic performance (AUC, 0.90) to SECT (AUC: 0.90 vs AUC: 0.87, respectively; P = .13) but was superior to radiography (AUC: 0.90 vs AUC: 0.82; P = .002). Overall diagnostic performance of DECT (AUC, 0.87) for the femur was superior to both SECT and radiography (P < .001). Conclusion Dual-energy CT had generally better diagnostic performance in detecting loosening of tibial and femoral components after total knee arthroplasty compared with single-energy CT or radiography.

ABSTRACT

Lateral extra-articular tenodesis (L.E.T.) have been proposed to reduce the tibia's anterior translation and internal rotation in concomitant to Anterior cruciate ligament (A.C.L.) reconstruction. Recent studies show that the addition of L.E.T. to A.C.L. reconstruction results in a statistically significant reduction in graft failure. The purpose of the present study was to evaluate the clinical outcomes, complications, and rate of return to preinjury sports level in pediatric patients who underwent combined A.C.L. reconstruction with L.E.T. at a minimum 2-year follow-up. The authors retrospectively evaluated 42 pediatric patients at high risk of graft failure who experienced ACLR connected to L.E.T. IKDC and Tegner-Lysholm Knee Scores Scale were used to assess clinical outcomes, and the Tegner Activity Scale to evaluate the return to sport. No graft failure or subsequent surgery related to A.C.L. reconstruction occurred. Furthermore, 88% of patients returned to the sport. Satisfactory clinical results were obtained on a short and medium-term follow-up. These findings help to consider this procedure for active adolescents at a high risk of graft failure to enhance A.C.L. reconstruction.

ABSTRACT

Snapping a knee related to a biceps femoris tendon subluxation is an uncommon syndrome that could be disabling in patients with high functional requirements such as athletes. We report a case of a 21-year-old soccer player with a painful left snapping biceps femoris tendon due to a varus trauma. He underwent knee arthroscopy and surgical exploration of the knee: the long head of the biceps femoris tendon was partially detached from his fibular insertion and there was a prominence on the fibular head. Reinsertion of the tendon and osteotomy of the fibular head allowed for resolution of all symptoms and the return to sport.

ABSTRACT

PURPOSE: Lateral unicompartmental arthroplasty (UKA) and distal femoral osteotomy (DFO) represent surgical solutions in cases of valgus malalignment and isolated lateral osteoarthritis (OA) of the knee. The aim of the present study was to assess the clinical results, complications, and the overall postoperative alignment of a series of DFO and lateral UKA with a minimum 2-year follow-up in active middle-aged patients. METHODS: Patients with valgus knee and isolated lateral OA who underwent opening-wedge DFO or UKA from 2017 to 2019 were reviewed. Each patient was characterized by a joint line convergence angle (JLCA) > 3° and mechanical lateral distal femoral angle (mLDFA) < 87°. We excluded patients who underwent meniscus or osteochondral allograft during DFO. The Oxford Knee Score (OKS), Knee Injury and Osteoarthritis Outcome Score (KOOS), complications, and postoperative alignment were assessed. Propensity score matching was used to identify comparable patients. RESULTS: The DFO and lateral UKA groups consisted of 29 patients each. No statistically significant differences in gender, age, body mass index (BMI), length of follow-up, or limb deformity were reported between the two groups. In the DFO group, OKS was reported to improve from 27.51 to 38.59 (p < 0.05) and KOOS from 51.14 to 67.2 (p < 0.05). Similarly, in the UKA group, OKS improved from 26.23 to 35.43 (p < 0.05) and KOOS from 50.12 to 65.91 (p < 0.05). However, the improvement in OKS and KOOS (delta) did not differ between groups (p = 0.35 and p = 0.95). The DFO and UKA groups were characterized by similar postoperative hip-knee-ankle (HKA) angle measurements of -3.26 and -3.00, respectively (p = 0.65). No patients in the UKA group underwent revision or other knee surgeries during follow-up. No infections were detected in either group. In the DFO group, no cases of nonunion or delayed union were reported. However, 40% of DFO patients underwent plate removal. One patient in each group was characterized by progression of medial OA with Kellgren-Lawrence (KL) grade > 3. CONCLUSION: UKA and DFO represent an effective treatment in lateral knee OA with intra-articular and extra-articular deformity. Both surgeries were able to provide a significant and comparable clinical improvement. LEVEL OF EVIDENCE: III, comparative retrospective cohort study.

ABSTRACT

The purpose of the present study was to assess, prospectively, the safety, clinical effectiveness, and feasibility of a single intra-articular injection of microfragmented adipose tissue in different stages of knee osteoarthritis (OA). The study included patients (aged 18−70 years), affected by OA (Kellgren−Lawrence I-IV). Unselected patients were evaluated before and prospectively after 6, 12, and 24 months from the injection. Visual analog scale (VAS) and knee injury and osteoarthritis outcome score (KOOS) were used for clinical evaluations. A total of 202 patients were eligible. The mean follow-up time in the cohort of patients was 24.5 ± 9.6 months. Total KOOS significantly improved from pre-operative baseline levels to 6-month follow-up (p < 0.001), and again between 6- and 12-month follow-ups (p < 0.001). The VAS showed a prompt reduction at 6 months (p < 0.001 vs. baseline), but then it increased again at 12 months compared to the 6-month assessment (p < 0.001), even though it remained lower than baseline (p < 0.001). At 24 months, patients with KL-IV demonstrated a lower improvement compared to baseline; patients that had undergone previous corticosteroid injections had a greater risk to further injection treatment. The collected clinical results suggest that MFAT may represent a safe and effective treatment for OA symptoms, offering a low-demanding and minimally invasive treatment.

ABSTRACT

PURPOSE: Parameniscal cysts are associate with horizontal meniscal tears. Arthroscopic meniscal repair and the excision of the cyst by mini-open approach represent a valid treatment. However, the recurrence of cyst is still a current issue. Therefore, biological factors may be considered to promote the biological repair and avoid recurrence. The aim of the present study was to report the clinical results and the rate of recurrence of the cyst after minimum 2-year of follow up in a cohort of patients treated by meniscal repair and autologous platelet-rich fibrin matrix augment. METHODS: Patients with lateral parameniscal cyst undergoing arthroscopic meniscal repair and autologous platelet-rich fibrin matrix augment between 2016 and 2019 were retrospectively reviewed in March 2021. Inclusion criteria were absence of prior surgery on the affected knee with minimum 2-year of follow-up. Exclusion criteria were concomitant ligament lesions, rheumatic diseases and knee osteoarthritis. After reviewing the database, each selected patient was contacted and asked to participate in the study; at the follow-up evaluation all patient signed an informed consent. Tegner-Lysholm knee score, IKDC and NRS were collected before surgery and at follow-up. RESULTS: This study included 15 patients (8 male) with mean age of 32.8 years old. No recurrence of the cysts was observed. The Tegner-Lysholm knee score and IKDC subjective scores increased respectively from 41.3 ± 5.4 and 37.6 ± 5.1 at baseline to 92.3 ± 4.6 and 89.4 ± 2.6 at the final follow up. Concerning pain relief, the Numeric Pain Rating Scale (NRS) displayed a significant improvement reaching at the follow up a score of 1,3 ± 1.1 in comparison to 6.8 ± 0.9 at the baseline. CONCLUSION: Surgical management of symptomatic lateral parameniscal cyst with cyst excision, autologous PRP membrane application and meniscus repair demonstrated excellent subjective clinical outcome with any cyst reoccurrence. LEVEL OF EVIDENCE: III, retrospective cohort study.

ABSTRACT

Parameniscal cysts are defined as an internal disorder of the knee joint. It is known that parameniscal cysts are associated with horizontal meniscal tears that could lead to the collection of synovial fluid within the cyst. Despite the treatment of meniscal tears, cyst recurrence is still an issue that needs to be addressed. In this regard, there has been an increasing interest in the use of biologic agents to enhance the vascularity and healing of the meniscus. Preliminary results for biologic therapeutic agents, such as growth factors, bone marrow, and aspirate concentrate, have been encouraging. However, these options are more demanding in regards to time, financial burden, resources, and so on. Autologous platelet-rich plasma is readily available, easy to use, affordable, and minimally invasive. This Technical Note will describe a step-by-step and reproducible technique for the harvesting, preparation, and use of an autologous platelet-rich fibrin matrix used to augment the healing of meniscal repairs.

ABSTRACT

Dual-energy computed tomography (DECT) has been reported to successfully identify bone marrow oedema (BME) in various traumatic settings. DECT has multiple strengths, including the availability of both a 3D view of the anatomical area studied and of high-resolution dual energy specific maps super-imposed onto conventional grayscale morphological images. Windowing can be used to enhance the visualization of BME by increasing the level of the super-imposed images. Conversely, by decreasing the level of the super-imposition of color-coded images, it is possible to progressively enhance the visualization of fine anatomical details, which is useful for diagnosing associated imaging findings. Importantly, bone sclerosis may represent an important pitfall for DECT, potentially generating both false positive and false negative findings by locally altering CT numbers. The aim of this paper was to evaluate the strengths and limitations of DECT in accurately detecting traumatic BME, by considering practical approaches to imaging at several anatomical sites.

ABSTRACT

Dual-energy computed tomography (DECT) is an imaging technique widely used in traumatic settings to diagnose bone marrow oedema (BME). This paper describes the role of DECT in diagnosing BME in non-traumatic settings by evaluating its reliability in analyzing some of the most common painful syndromes. In particular, with an illustrative approach, the paper describes the possible use of DECT for the evaluation of osteochondral lesions of the knee and of the ankle, avascular necrosis of the hip, non-traumatic stress fractures, and other inflammatory and infectious disorders of the bones.

ABSTRACT

PURPOSE: The objective of this study was to evaluate the safety and the efficacy of intra-articular injections of autologous micro-fragmented adipose tissue in patients affected by early or moderate ankle osteoarthritis (AOA). METHODS: A total of 31 symptomatic patients, aged 28-71 years, affected by AOA, were treated with 5 ml of autologous micro-fragmented adipose tissue. Clinical evaluations before the treatment and after six, 12, and 24 months were performed through American Orthopaedic Foot and Ankle Society (AOFAS) scale, the Foot and Ankle Disability Index (FADI), and Visual Analogue Scale (VAS) scores. Adverse events were recorded. RESULTS: No severe complications were noted during the treatment and the follow-up period. A statistically significant improvement from basal evaluation to the six, 12-, and 24-month follow-up visit was observed, whereas a statistically significant worsening from the 12-month to the 24-month follow-up visit was showed. CONCLUSION: The autologous micro-fragmented adipose tissue for the treatment of pain in ankle osteoarthritis seems safe and able to provide positive clinical outcomes, potentially offering a new minimally invasive therapeutic option for patients who are not eligible for more invasive approaches. Further high-quality studies are needed to confirm these findings.

ABSTRACT

The novel coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has greatly changed our way of living and working. We have developed a method to treat urgent patients in a safe way, and we applied the same protocol to resume elective surgical procedures. METHODS: We reorganized the system and the management of our orthopaedic department to perform elective surgical procedures in a safe way. During the COVID-19 lockdown, 614 patients underwent elective orthopaedic procedures. RESULTS: No major postoperative complications were recorded. None of the orthopaedic surgeons, health-care personnel, or hospitalized patients was infected in this period of activity. CONCLUSIONS: During COVID-19, it is possible to perform elective surgical procedures in a safe way.

ABSTRACT

PURPOSE: The posterolateral corner (PLC) is more likely to be injured in combination with the posterior cruciate ligament (PCL) or the anterior cruciate ligament than in isolation. This leads to instability of the knee and loss of function. We hypothesised that combined PCL and PLC reconstruction would restore sufficient stability to allow improvement in patient symptoms and function. METHODS: 19 patients who underwent arthroscopic-assisted single-bundle PCL and PLC reconstruction by a single surgeon were analysed retrospectively. The PLC reconstruction was a modified Larson reconstruction of the lateral collateral ligament and the popliteofibular ligament. The IKDC and Tegner scores were used to assess outcome. Dial test and varus laxity were used to assess improvements in clinical laxity. Posterior laxity was tested using the KT-1000. RESULTS: The mean follow-up was 38 months (±(2× standard deviations), ±12.3). There were no postoperative complications. All patients had less than 5 mm posterior step-off. 17 of 19 patients had negative dial and varus stress tests. Measured range of motion was reduced by a mean of 10°, but patients did not report any daily activities restrictions. Tegner scores improved from a median pre-operative value of 2 (range 1-4) to 6 (4-9) at final follow-up. The mean postoperative IKDC score was 86 (±11). CONCLUSIONS: Subjectively, the knee stability achieved allowed daily activities. However, there were remaining abnormalities in range of motion, posterior drawer and rotational laxity, suggesting that normal knee laxity was not restored. LEVEL OF EVIDENCE: IV.

ABSTRACT

Failure of repair of the patellar tendon is uncommon. It may occur in association with chronic systemic diseases or after administration of corticosteroid and quinolones. We report the reconstruction of the patellar tendon with allograft, after failed primary repair, of a 23-year-old young with Ehlers-Danlos syndrome.

ABSTRACT

BACKGROUND: The occurrence of a primary intramuscular infestation of Echinococcus granulosus is extremely rare. CASE: A 70-year-old woman with primary skeletal muscle hydatidosis initially presented with a soft tissue mass. Clinical and radiologic examination revealed a huge cystic mass in the right quadriceps muscle without any visceral organ involvement. Since the differential diagnosis included a soft tissue tumor, fine needle aspiration cytology was performed, and a diagnosis of hydatid disease was made. CONCLUSION: This very rare case of primary intramuscular infestation of E granulosus was clinically misdiagnosed as a soft tissue tumor. Hydatid disease, albeit rare, should be considered in the differential diagnosis of a soft tissue mass.
