Davies PSE, Anderson J, Goldberg M, Dabis J, Stillwell A, McMeniman T, Myers PT. Fibrin clot augmentation of high-risk meniscal repairs may result in clinical healing in up to 90% of cases. J ISAKOS 2024:100316. [PMID: 39216540 DOI: 10.1016/j.jisako.2024.100316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Revised: 08/22/2024] [Accepted: 08/26/2024] [Indexed: 09/04/2024]
Abstract
OBJECTIVE While meniscal repair is preferable to meniscectomy, some cases may be at higher risk of failure if repaired. Incorporating fibrin clot (FC) into the repair has been proposed to improve healing rates. The purpose of this study was to determine the failure rates, patient reported outcome measures (PROMs) and complications of FC augmented meniscal repair for cases considered to be at higher risk of failure. METHODS A retrospective case series of all patients undergoing FC augmented repair of isolated meniscus tears between January 2016 and September 2021 was undertaken. All cases were thought be at higher risk of failure; they included chronic, radial, complex, horizontal cleavage, and tears not in the red - red zone. Patients were excluded if they had a concomitant anterior cruciate ligament (ACL) reconstruction or if the repair was done through an open incision. The primary outcome was clinical failure defined as further repair or debridement. Secondary outcomes were PROMs and surgical complications. PROMs collected were Lysholm score, Knee injury and Osteoarthritis Outcome Score, Oxford Knee Score and the Tegner score. RESULTS 51 inside-out meniscal repairs using FC were performed in 50 patients (62% male). The mean age was 34 years (range 14-70). The median time from injury to repair was 122 days (range 4-1565). The medial meniscus was repaired in 63% of cases. Tear types included radial (31%) and complex (39%) and 71% of cases included repair of the white-white zone. 16% of cases were revision meniscal repairs. FC was used in 43% of isolated meniscal repairs during the study period. All patients were followed up to a median of 46 months (range 22-87 months). PROMs at a median of 30 months post-operatively showed statistically significant improvements. Five patients (10%) underwent further surgery for failure after median 21 months. Two patients (4%) reported sensory disturbance around their skin wounds, no other complications were reported. 13% of medial meniscal repairs failed, whereas only 5% of lateral meniscal repairs failed (p=0.4). CONCLUSIONS FC augmented meniscal repair performed for tears considered to be at higher risk of failure may result in acceptably low rates of clinical failure. LEVEL OF EVIDENCE Level IV, case series.

Thick-Shell Sulcus Deepening Trochleoplasty for Recurrent Patellar Dislocation Leads to Clinically Meaningful Improvements and High Patient Satisfaction in Adolescents with Open Physes. J ISAKOS 2024:100315. [PMID: 39197680 DOI: 10.1016/j.jisako.2024.100315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2024] [Revised: 08/20/2024] [Accepted: 08/21/2024] [Indexed: 09/01/2024]
Abstract
OBJECTIVES To evaluate clinical and radiological outcomes of thick-shell, sulcus deepening trochleoplasty in patients with open distal femoral physes and less than two years of growth remaining. We hypothesized that patients would have clinical and radiographic improvements in addition to high patient reported outcomes following thick-shell, sulcus deepening trochleoplasty. METHODS Bone age was determined on preoperative Magnetic Resonance Imaging (MRI) using the Pennock Knee Bone Age Atlas. Pre- and postoperative radiographs were used to measure the anatomic lateral distal femoral angle (aLDFA) and Blumensaat angle. International Knee Documentation Committee (IKDC), Kujala, and numerical patient satisfaction scores were assessed. Pre- and postoperative aLDFA and Blumensaat angles as well as well as patient reported outcomes were analyzed via the Wilcoxon signed rank test. RESULTS Seventeen adolescents (21 knees) with DeJour Types B and D trochlear dysplasia and open distal femoral physes underwent Dejour thick-shell, sulcus-deepening trochleoplasty at a single institution. In twelve females (16 knees, 76.2%) the median chronological and bone ages at time of operation was 14.9 and 14.3 years, respectively. In 5 males (5 knees, 27.7%), the median chronological and bone ages at time of operation were 15.7 and 15.2 years, respectively. Mean follow-up time was 64 months postoperatively. Physes were closed in all knees at the time of final clinical and radiographic follow-up. The mean change in aLDFA and Blumensaat Angle was 0.73 (p = 0.1074, 95% CI -0.09 - 1.57) and 0.88 degrees (p=0.0477, 95% CI 0.10 - 1.88), respectively. Median IKDC scores improved from 57.3 preoperatively to 90.9 postoperatively, for a mean difference of 26.1 (p = 0.00064, 95% CI 18.0 - 34.2). Median Kujala scores improved from 55.0 preoperatively to 95.0 postoperatively, for an mean change of 30.2 (p = 0.0008, 95% CI 19.6 - 40.8). Overall mean numerical patient satisfaction was high (mean 9.26/10). One of 21 knees (4.8%) underwent additional surgery to address recurrent patellar instability. CONCLUSION Thick-shell sulcus deepening trochleoplasty for addressing recurrent lateral patellar instability in patients with open distal femoral physes and less than two years of growth remaining is safe and provides clinically meaningful improvements in addition to high patient satisfaction when combined with other patellar stabilization procedures.

The Effectiveness of Treating Osgood-Schlatter Disease (OSD) with Leukocyte-Rich Platelet-Rich Plasma (LR-PRP) Depending on the Duration of the Disease. J Clin Med 2024; 13:4220. [PMID: 39064260 PMCID: PMC11278405 DOI: 10.3390/jcm13144220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2024] [Revised: 07/11/2024] [Accepted: 07/16/2024] [Indexed: 07/28/2024] Open
Abstract
Background: Osgood-Schlatter disease (OSD) occurs mainly in physically active adolescents, causing significant physical activity restrictions. The aim of this study is to compare the effectiveness of treating OSD with leukocyte-rich platelet-rich plasma (LR-PRP) depending on the duration of the disease and to attempt to develop an alternative treatment method to the currently used conservative therapy. Methods: Treatment efficacy was evaluated using the VAS, Tegner, Lysholm, and KOOS scales. Subject satisfaction, return to sports activity, potential adverse effects, and X-ray evaluation were likewise used to assess the success of the procedure. Results: Analysis across all scales showed statistically significant treatment effectiveness with LR-PRP in both groups of patients. When comparing the two groups, significantly better treatment outcomes were achieved in the acute phase of OSD. Treatment satisfaction in the acute OSD group was 95%, compared to 64% in the chronic group. The MCID value after LR-PRP injection in acute OSD compared to chronic OSD reached 100% vs. 81% on the VAS scale, 95.5% vs. 55% on the Tegner scale, 95% vs. 47% on the Lysholm scale and 91% vs. 27% on the KOOS scale. No adverse effects were recorded in either group. Conclusions: The high efficacy of LR-PRP treatment in patients with acute OSD, in correlation with high safety, as well as rapid and lasting results, can be an effective and beneficial alternative to conservative treatment. This single procedure seems particularly justified in a group of young professional athletes, where absence from training can lead to serious consequences.

Arthroscopy 2024:S0749-8063(24)00496-1. [PMID: 38992511 DOI: 10.1016/j.arthro.2024.06.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 05/31/2024] [Accepted: 06/20/2024] [Indexed: 07/13/2024]
Abstract
PURPOSE To compare patient-reported outcomes (PROs), failure, and healing rates after all-inside (AI) repair versus inside-out (IO) repair for the treatment of meniscal radial tears. METHODS A literature search was performed according to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines using the Scopus, PubMed, and Embase computerized databases. Level of Evidence I through IV human clinical studies evaluating PROs and/or the incidence of failure and healing after AI versus IO repairs for meniscal radial tears were included. Clinical failure was defined by the presence of joint-line tenderness; a positive McMurray test; and mechanical symptoms, such as locking, catching, or giving way. Study quality was assessed using the Methodological Index for Non-Randomized Studies criteria and the Modified Coleman Methodology Score. RESULTS Ten studies published from 2008 to 2023 comprising 205 patients were identified, including 142 patients who underwent AI repair and 63 patients who underwent IO repair for radial meniscus tears. Postoperative Lysholm and Tegner scores ranged from 90.8 to 95.6 and 5.7 to 8.2, respectively, in the AI repair group, compared with 86.9 to 94.2 and 6 to 7.5, respectively, in the IO repair group. All patients exceeded published values for minimal clinically important difference for the Lysholm score. Clinical failure ranged from 0% to 40% in the AI group and 0% to 62.5% in the IO group. Healing assessments on second-look arthroscopy revealed failure rates ranging from 0% to 13.3% in the AI group and 0% to 39% in the IO group. Complete and partial healing ranged from 28.6% to 92.3% in the AI group and from 25% to 70% in the IO group. Chondral damage on second-look arthroscopy ranged from 0% to 95% in the IO group and 0% to 57.7% in the AI group. Postoperative complications ranged from 0% to 2% within the AI group, whereas no complications were reported in the IO group. No implant-related complications were reported in any study group. CONCLUSIONS Both all-inside and inside-out repairs for meniscal radial tears demonstrated improved PROs; however, current literature suggests that the IO technique may have higher failure rates both clinically and on second-look arthroscopy.

Knee Surg Sports Traumatol Arthrosc 2024. [PMID: 38967273 DOI: 10.1002/ksa.12316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 05/27/2024] [Accepted: 06/03/2024] [Indexed: 07/06/2024]
Abstract
PURPOSE The purpose of this study was to evaluate the radiographic and clinical outcomes of sulcus-deepening trochleoplasty at a minimum follow-up of 23 years. METHODS The authors evaluated a retrospective series of 10 patients (11 knees) who underwent trochleoplasty between 1993 and 2000. All patients were assessed at a minimum follow-up of 23 years by an independent clinician who noted any patellar redislocations and collected the International Knee Documentation Committee (IKDC), Kujala scores and range of motion. Radiographic examination was performed to assess patellofemoral arthritis using the Iwano classification. RESULTS A total of 11 knees, from five women and five men aged 25.6 ± 6.9 years (range, 15-47 years) underwent trochleoplasty during the inclusion period. All 11 knees underwent adjuvant procedures during trochleoplasty (100%): 10 had tibial tuberosity osteotomy (TTO) and vastus medialis plasty and 1 had only vastus medialis plasty (had prior TTO). At a follow-up of 24.4 ± 2.1 years (range, 23-30 years), two patients were lost to follow-up (18%). The Iwano classification was Grade 1 in three patients (33%), Grade 2 in four patients (44%) and Grade 4 in two patients (22%). The flexion range was 130 ± 8.7° and satisfaction was 9.2 ± 0.7, Kujala was 76.9 ± 8.5 and IKDC was 65.5 ± 13.8. CONCLUSION At 23-30 years following sulcus-deepening trochleoplasty in this small series of 10 patients (11 knees), patients had satisfactory clinical scores, only 1 patient reported an episode of traumatic patellar dislocation, and two knees had patellofemoral arthritis of Iwano Grade >2 (22%).

Abstract
Purpose The aim of the present study is to define the minimal clinically important difference (MCID) for International Knee Documentation Committee (IKDC) and Knee Injury and Osteoarthritis Outcome Score (KOOS) for patients undergoing tibial tubercle osteotomy (TTO) for either (1) patellofemoral pain or (2) patellar instability. Methods Patients undergoing TTO for either patellofemoral pain or patellar instability by one of two sports medicine fellowship-trained surgeons at a single institution between September 2014 and May 2023 were included in the study. IKDC and KOOS scores were collected preoperatively and minimum 1 year postoperatively. Distribution-based methods were used to calculate the MCID. Results Seventy-seven patients (82 knees) were included, with a median age of 29.3 years (interquartile range [IQR]: 22.2-36.3 years) and a median BMI of 24.5 kg/m2 [IQR: 22.3-28.3 kg/m2]. Fifty-seven patients (74%) were female, and there were 40 right knees (49%). The median time to IKDC and KOOS score was 1.8 and 1.7 years, respectively. Forty-five patients (46 knees) underwent TTO for patellofemoral instability, and 32 patients (36 knees) underwent TTO for patellofemoral pain. The MCID was 11.5 for IKDC, 10.2 for KOOS pain, 10.1 for KOOS symptoms, 9.9 for KOOS ADL, 14.2 for KOOS sport and 14.2 for KOOS QoL for patients undergoing TTO for patellofemoral pain. The MCID was 11.2 for IKDC, 10.1 for KOOS pain, 10.6 for KOOS symptoms, 10.2 for KOOS ADL, 16.0 for KOOS sport and 13.2 for KOOS QoL for patients undergoing TTO for patellar instability. Conclusion We define the MCIDs for commonly used patient-reported outcome measures for patients undergoing TTO for either patellofemoral pain or patellar instability. Level of Evidence Level II.

Abstract
PURPOSE To assess the postoperative outcomes of double-level knee derotational osteotomy (KDRO) combined with medial patellofemoral ligament reconstruction (MPFLR) and to compare it with tibial tuber transfer (TTT) and MPFLR without derotational osteotomy in patients with recurrent patellar instability and a marked torsional deformity. METHODS From March 2020 to December 2021, patients with torsion deformity (combined femoral torsion [FT] and tibial torsion [TTn] ≥30°) were retrospectively included. The minimum follow-up time was 18 months. Patients who received KDRO and MPFLR were categorized as the KDRO group and patients who received a combined TTT and MPFLR were categorized as the control group. Preoperative and postoperative clinical symptoms, patient-reported outcomes (Kujala, visual analog scale, Lysholm, International Knee Documentation Committee, Tegner, and Knee Injury and Osteoarthritis Outcome scores), and imaging parameters (FT, TTn, patellar height, femoral trochlear dysplasia, congruence angle, patellar tilt angle, lateral patellar angle, lateral patellar translation, and tibial tubercle-trochlear groove distance) were analyzed. RESULTS In all, 36 patients were included with 18 in KDRO group and 18 in control group. The mean follow-up time was 30 (range 21-39) months. At the latest follow-up, no patient experienced redislocation in either group. Except for the FT and TTn in the control group, postoperative imaging parameters were significantly reduced to the normal range. KDRO group had a lower patellar tilt angle (P = .043, effect size 0.64). All clinical scores in both groups significantly improved postoperatively. The KDRO group had better functional scores than control group except the KOOS daily living activities subscore and the KOOS sports and recreation subscore. More patients in the KDRO group met the minimal clinically important difference for most patient-reported outcomes than the control group. Eight patients (44%) in the control group complained of postoperative anterior knee pain, compared with 1 patient (6%) in the KDRO group (P = .018). CONCLUSIONS KDRO combined with MPFLR was associated with better postoperative outcomes than TTT combined with MPFLR in patients with recurrent patellar instability and a torsion deformity.

Derotational distal femoral osteotomy corrects excessive femoral anteversion in patients with patellofemoral instability: A systematic review. Knee Surg Sports Traumatol Arthrosc 2024; 32:713-724. [PMID: 38385776 DOI: 10.1002/ksa.12097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 01/25/2024] [Accepted: 02/04/2024] [Indexed: 02/23/2024]
Abstract
PURPOSE Patellofemoral instability (PFI) is a common condition that can be caused from multiple factors, including lower limb rotational malalignments. Determining precise criteria for performing corrective torsional osteotomy can be a daunting task due to the lack of consensus on normal and excessive values and the limited evidence-based data in the postoperative results. The purpose was to assess the clinical, functional and imaging outcomes following derotational distal femoral osteotomy (DDFO) in patients with PFI and/or anterior knee pain (AKP) associated with lower limb rotational malalignments. METHODS Searches were conducted on PubMed, EMBASE and Web of Science databases up to October 2023. Studies reporting outcomes after DDFO in patients with PFI and/or AKP were eligible for the systematic review. The primary outcome was imaging metrics, especially femoral anteversion. Secondary outcomes included the patient-reported outcome measures (PROMs) (clinical and functional). Quantitative synthesis involved the use of weighted averages to calculate pre- to postoperative mean differences (MD) and compare them against the minimal clinically important difference (MCID). RESULTS Ten studies (309 knees) were included with a mean follow-up of 36.1 ± 11.7 months. Imaging outcomes consistently indicated the correction of femoral anteversion (MD = -19.4 degrees, 95% confidence interval: -20.1 to -18.7) following DDFO. PROMs showed significant improvements in most studies, exceeding the MCID. Patient satisfaction with the DDFO was high (93.3%). CONCLUSIONS The DDFO was an effective treatment option for correcting excessive femoral anteversion in patients with PFI associated with clinically relevant functional and clinical improvement and a high satisfaction rate.
