J Arthroplasty 2024:S0883-5403(24)00629-6. [PMID: 38908537 DOI: 10.1016/j.arth.2024.06.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 06/11/2024] [Accepted: 06/13/2024] [Indexed: 06/24/2024] Open
Abstract
BACKGROUND The surgical management of large osteochondral lesions of the femoral head in young, active patients remains controversial. Fresh osteochondral allograft (OCA) transplantation can be a highly effective treatment for these lesions in some patients. This study investigated survivorship as well as clinical and radiographic outcomes after fresh OCA transplantation at a minimum 2-year follow-up (mean, 6.6 years; range, 0.6 to 13.7 years). METHODS A retrospective review of 29 patients who underwent plug OCA transplantation for focal femoral head osteochondral lesions between 2008 and 2021 was performed. Patients were assessed clinically using the modified Harris Hip score (mHHS) preoperatively and at each follow-up visit. Postoperative radiographs were evaluated for graft integrity and osteoarthritis severity. Kaplan-Meier survivorship analyses with 95% confidence intervals (CIs) were performed for the endpoint of conversion to total hip arthroplasty (THA). RESULTS Overall graft survivorship for included patients was 78.4% (95% CI: 62.9 to 93.9) and 62.7% (95% CI: 39.6 to 85.8) at 5 and 10 years, respectively. There were ten patients (34.5%) who underwent conversion to THA. There was a significant difference using the log-rank test between survival for patients who had a preoperative diagnosis of osteonecrosis (ON) versus those who had other diagnoses (P = .002). The ten-year survival for those who had ON was 41.8% (95% CI: 4.8 to 78.8), and the ten-year survival for diagnoses other than ON was 85.7% (95% CI: 59.8 to 100). The mean mHHS score improved significantly (P < .001) from 48.9 (19 to 84) preoperatively to 77.4 (35 to 100) at the final follow-up. There were twenty patients (69.0%) who had mHHS ≥ 70 at the latest follow-up. Arthritic progression, indicated by an increase in the Kellgren and Lawrence grade, occurred in 7 hips (26.9%). CONCLUSIONS An OCA transplantation is a viable treatment option for osteochondral defects of the femoral head in young, active patients who have minimal preexisting joint deformity. It may delay the progression of arthritis and the need for THA. Patients who had a preoperative diagnosis of ON had worse clinical outcomes than those who had other diagnoses.

Outcomes of Arthroscopic Joint Preservation Techniques for Chondral Lesions in the Hip: An Updated Systematic Review. Arthroscopy 2024; 40:1670-1686. [PMID: 38040390 DOI: 10.1016/j.arthro.2023.11.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 11/01/2023] [Accepted: 11/23/2023] [Indexed: 12/03/2023]
Abstract
PURPOSE To systematically review outcomes of joint preservation procedures for chondral lesions of the hip through analysis of survival rates and patient-reported outcomes (PROs). METHODS A literature search from 2018 to May 2023 was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in 3 databases: PubMed, Embase, and Google Scholar. Studies were included if they reported on outcomes of patients undergoing hip arthroscopy for the treatment of chondral lesions of the hip joint and if there were quantifiable postoperative outcome measures. Quality assessment was completed using the Methodological Index for Non-Randomized Studies criteria. RESULTS Twenty-seven studies were included, with 20 noncomparative and 7 comparative studies. Microfracture (MFx) was the most common procedure, reported in 17 studies. Other procedures include autologous chondrocyte transplantation (ACT) (5 studies), autologous matrix-induced chondrogenesis (AMIC) (3 studies), and MFx in conjunction with CarGel (3 studies). Seven other novel procedures were reported in individual separate studies. Survival rates, defined by no revision surgery or conversion to total hip arthroscopy (THA) at latest follow-up, for MFx (14 studies), AMIC (3 studies), and MFx in conjunction with CarGel (3 studies) ranged from 59.1% to 100%, 92.9% to 100%, and 94.4% to 95.7%, respectively. Survival rates of ACT, biological reconstruction, debridement and abrasion, microfragmented autologous adipose tissue transplantation, and ChondroFiller gel were all reported once in separate studies with rates of 100%, 100%, 85.4%, 100%, and 92.3%, respectively. All studies included PROs, most reporting statistically significant improvements (P < .05) at the latest follow-up. CONCLUSIONS Isolated MFx remained the most commonly performed technique, but with lower survival and higher conversion to THA rates than in studies before 2018. Novel techniques that were performed in conjunction with MFx or that avoided MFx altogether had higher overall survival rates despite being minimally performed. Most patients across all techniques demonstrated significant improvements in PROs. LEVEL OF EVIDENCE Level IV, systematic review of Level III and IV studies.

Beck EC, Trasolini NA. Editorial Commentary: Osteochodral Autograft and Allograft Show Favorable Outcomes for High-Grade Hip Femoral Cartilage Lesions, but Caution Is Required for Impaction Injuries and Osteonecrosis. Arthroscopy 2024:S0749-8063(24)00295-0. [PMID: 38677565 DOI: 10.1016/j.arthro.2024.03.048] [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: 03/19/2024] [Revised: 03/30/2024] [Accepted: 03/30/2024] [Indexed: 04/29/2024]
Abstract
Articular cartilage defects of the hip pose therapeutic challenges. Among patients undergoing hip arthroscopy for femoroacetabular impingement syndrome, more than 20% may have partial- or full-thickness chondral damage, and patients with high-grade (International Cartilage Repair Society grade 3 or 4) damage who undergo arthroscopic treatment of femoroacetabular impingement syndrome have higher rates of reoperation at 10-year follow-up. Arthroscopic and open techniques have been developed to translate cartilage restoration options initially developed in the knee for use in the hip. Arthroscopic options include chondroplasty, microfracture, biologic cartilage scaffolds, autologous chondrocyte implantation, and minced cartilage autograft (albeit more commonly in the acetabulum than the femoral head). Open techniques include autologous chondrocyte grafting, osteochondral autograft transfer (including mosaicplasty), osteochondral allograft transplantation, and arthroplasty. Open osteochondral allograft and autograft transplantation show improved patient-reported outcomes and forestall arthroplasty in young patients with high-grade cartilage defects of the femoral head. A recent review shows survivorship of 70% to 87.5% for allograft and 61.5% to 96% for autograft. At the same time, outcomes are not universally positive, particularly for patients with posttraumatic impaction injuries and high-grade osteonecrosis. Until further data better clarify the indications and contraindications, widespread adoption of open cartilage transplantation to the femoral head should be approached with caution, especially for older patients, in whom the gold standard of total hip arthroplasty has excellent survivorship at long-term follow-up.

Osteochondral Allograft or Autograft Transplantation of the Femoral Head Leads to Improvement in Outcomes but Variable Survivorship: A Systematic Review. Arthroscopy 2024:S0749-8063(24)00128-2. [PMID: 38365122 DOI: 10.1016/j.arthro.2024.02.008] [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: 10/07/2023] [Revised: 01/22/2024] [Accepted: 02/08/2024] [Indexed: 02/18/2024]
Abstract
PURPOSE To review patient-reported outcomes (PROs) and survivorship in patients undergoing osteochondral autograft or allograft transplantation (OAT) of the femoral head. METHODS PubMed, Cochrane Center for Register of Controlled Trials, and Scopus databases were searched in November 2022 with an updated search extending to December 2023 using criteria from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the following keywords: (hip OR femoral head) AND (mosaicplasty OR osteochondral allograft OR osteochondral autograft OR osteochondral lesion). Articles were included if they evaluated postoperative PROs in patients who underwent OAT of the femoral head and had a study size of 5 or more hips (n ≥ 5). Survivorship was defined as freedom from conversion to total hip arthroplasty. For PROs evaluated in 3 studies or more, forest plots were created and I2 was calculated. RESULTS Twelve studies were included in this review, with a total of 156 hips and a mean follow-up time ranging between 16.8 and 222 months. In total, 104 (66.7%) hips were male while 52 (33.3%) were female. Age of patients ranged from 17.0 to 35.4 years, while body mass index ranged from 23.3 to 28.1. Eight studies reported on osteochondral autograft transplantation and 4 studies on osteochondral allograft transplantation. Three studies reported significant improvement in at least 1 PRO. Survivorship ranged from 61.5% to 96% at minimum 2-year follow-up and from 57.1% to 91% at minimum 5-year follow-up. At a follow-up of less than 5 years, osteochondral allograft transplantation studies showed 70% to 87.5% survivorship, while autograft varied from 61.54% to 96%. CONCLUSIONS Patients with osteochondral lesions of the femoral head who underwent osteochondral autograft or allograft transplantation demonstrated improved PROs but variable survivorship rates. LEVEL OF EVIDENCE Level IV, systematic review of Level IV studies.
