Background:
Chronic lateral ankle instability (CLAI) is associated with the presence or development of intra-articular pathologies such as chondral or osteochondral lesions, or (O)CLs. Currently, the ...incidence of (O)CLs in patients with CLAI is unknown.
Purpose:
To determine the incidence of (O)CLs in patients with CLAI.
Study Design:
Systematic review and meta-analysis; Level of evidence, 4.
Methods:
A literature search was conducted in the PubMed (MEDLINE), Embase (Ovid), and Cochrane databases for articles published from January 2000 until December 2020. Two authors independently screened the search results and conducted the quality assessment using the methodological index for non-randomized studies (MINORS) criteria. Clinical studies were included that reported findings on the presence of ankle (O)CLs based on pre- or intraoperative diagnostic measures in patients with CLAI (>6 months of symptoms). Patient and lesion characteristics were pooled using a simplified method. Lesion characteristics included localization and chondral and osteochondral involvement. The primary outcome was the incidence of (O)CLs in ankles with CLAI. A random-effects model with 95% CIs was used to analyze the primary outcome. The distribution of (O)CLs in the ankle joint was reported according to talar or tibial involvement, with medial and lateral divisions for talar involvement.
Results:
Twelve studies were included with 2145 patients and 2170 ankles with CLAI. The pooled incidence of (O)CLs in ankles with CLAI was 32.2% (95% CI, 22.7%-41.7%). Among all lesions, 43% were chondral and 57% were osteochondral. Among all (O)CLs, 85% were located on the talus and 17% on the distal tibia. Of the talar (O)CLs, 68% were located medially and 32% laterally.
Conclusion:
(O)CLs were found in up to 32% of ankles with CLAI. The most common location was the talus (85%). Furthermore, most lesions were located on the medial talar dome (68%). These findings will aid physicians in the early recognition and treatment of ankle (O)CLs in the context of CLAI.

Purpose
To determine the incidence and location of osteochondral lesions (OCLs) following ankle fractures as well as to determine the association between fracture type and the presence of OCLs. Up to ...50% of patients with ankle fractures that receive surgical treatment show suboptimal functional results with residual complaints at a long-term follow-up. This might be due to the presence of intra-articular osteochondral lesions (OCL).
Methods
A literature search was carried out in PubMed (MEDLINE), EMBASE, CDSR, DARE and CENTRAL to identify relevant studies. Two authors separately and independently screened the search results and conducted the quality assessment using the MINORS criteria. Available full-text clinical articles on ankle fractures published in English, Dutch and German were eligible for inclusion. Per fracture classification, the OCL incidence and location were extracted from the included articles. Where possible, OCL incidence per fracture classification (Danis–Weber and/or Lauge–Hansen classification) was calculated and pooled. Two-sided
p
values of less than 0.05 were considered statistically significant.
Results
Twenty articles were included with a total of 1707 ankle fractures in 1707 patients. When focusing on ankle fractures that were assessed directly after the trauma, the OCL incidence was 45% (
n
= 1404). Furthermore, the most common location of an OCL following an ankle fractures was the talus (43% of all OCLs). A significant difference in OCL incidence was observed among Lauge–Hansen categories (
p
= 0.049). Post hoc pairwise comparisons between Lauge–Hansen categories (with adjusted significance level of 0.01) revealed no significant difference (n.s.).
Conclusion
OCLs are frequently seen in patients with ankle fractures when assessed both directly after and at least 12 months after initial trauma (45–47%, respectively). Moreover, the vast majority of post-traumatic OCLs were located in the talus (42.7% of all OCLs). A higher incidence of OCLs was observed with rotational type fractures. The clinical relevance of the present systematic review is that it provides an overview of the incidence and location of OCLs in ankle fractures, hereby raising awareness to surgeons of these treatable concomitant injuries. As a result, this may improve the clinical outcomes when directly addressed during index surgery.

Purpose
The purpose of the present study was to evaluate the clinical and radiological outcomes of arthroscopic bone marrow stimulation (BMS) for the treatment of osteochondral lesions of the talus ...(OLTs) at long-term follow-up.
Methods
A literature search was conducted from the earliest record until March 2021 to identify studies published using the PubMed, EMBASE (Ovid), and Cochrane Library databases. Clinical studies reporting on arthroscopic BMS for OLTs at a minimum of 8-year follow-up were included. The review was performed according to the PRISMA guidelines. Two authors independently conducted the article selection and conducted the quality assessment using the Methodological index for Non-randomized Studies (MINORS). The primary outcome was defined as clinical outcomes consisting of pain scores and patient-reported outcome measures. Secondary outcomes concerned the return to sport rate, reoperation rate, complication rate, and the rate of progression of degenerative changes within the tibiotalar joint as a measure of ankle osteoarthritis. Associated 95% confidence intervals (95% CI) were calculated based on the primary and secondary outcome measures.
Results
Six studies with a total of 323 ankles (310 patients) were included at a mean pooled follow-up of 13.0 (9.5–13.9) years. The mean MINORS score of the included studies was 7.7 out of 16 points (range 6–9), indicating a low to moderate quality. The mean postoperative pooled American Orthopaedic Foot and Ankle Society (AOFAS) score was 83.8 (95% CI 83.6–84.1). 78% (95% CI 69.5–86.8) participated in sports (at any level) at final follow-up. Return to preinjury level of sports was not reported. Reoperations were performed in 6.9% (95% CI 4.1–9.7) of ankles and complications related to the BMS procedure were observed in 2% (95% CI 0.4–3.0) of ankles. Progression of degenerative changes was observed in 28% (95% CI 22.3–33.2) of ankles.
Conclusion
Long-term clinical outcomes following arthroscopic BMS can be considered satisfactory even though one in three patients show progression of degenerative changes from a radiological perspective. These findings indicate that OLTs treated with BMS may be at risk of progressing towards end-stage ankle osteoarthritis over time in light of the incremental cartilage damage cascade. The findings of this study can aid clinicians and patients with the shared decision-making process when considering the long-term outcomes of BMS.

Purpose
The purpose of this study was to describe the mid-term clinical and radiological results of a novel arthroscopic fixation technique for primary osteochondral defects (OCD) of the talus, named ...the lift, drill, fill and fix (LDFF) technique.
Methods
Twenty-seven ankles (25 patients) underwent an arthroscopic LDFF procedure for primary fixable talar OCDs. The mean follow-up was 27 months (SD 5). Pre- and post-operative clinical assessments were prospectively performed by measuring the Numeric Rating Scale (NRS) of pain in/at rest, walking and when running. Additionally, the Foot and Ankle Outcome Score (FAOS) and the Short Form-36 (SF-36) were used to assess clinical outcome. The patients were radiologically assessed by means of computed tomography (CT) scans pre-operatively and 1 year post-operatively.
Results
The mean NRS during running significantly improved from 7.8 pre-operatively to 2.9 post-operatively (
p
= 0.006), the NRS during walking from 5.7 to 2.0 (
p
< 0.001) and the NRS in rest from 2.3 to 1.2 (
p
= 0.015). The median FAOS at final follow-up was 86 for pain, 63 for other symptoms, 95 for activities of daily living, 70 for sport and 53 for quality of life. A pre- and post-operative score comparison was available for 16 patients, and improved significantly in most subscores. The SF-36 physical component scale significantly improved from 42.9 to 50.1. Of the CT scans at 1 year after surgery, 81% showed a flush subchondral bone plate and 92% of OCDs showed union.
Conclusion
Arthroscopic LDFF of a fixable primary talar OCD results in excellent improvement of clinical outcomes. The radiological follow-up confirms that fusion of the fragment is feasible in 92%. This technique could be regarded as the new gold standard for the orthopedic surgeon comfortable with arthroscopic procedures.

Needle arthroscopy has enjoyed a tremendous growth concerning the quality of intraoperative images due to technical innovation, resulting in innovative possibilities concerning concomitant minimally ...invasive procedures and treatment of osteochondral lesions of the talus (OLT). These lesions have increasingly been receiving scientific attention in the orthopaedic (sports) medicine field, and, as such, the quality of evidence-based treatment for them has developed substantially. Treatment of OLTs—and specifically subchondroplasty. OLTs may also be suitable for needle arthroscopic interventions. The purpose of the present technical note is, therefore, to present an all-arthroscopic needle arthroscopic technique, including subchondroplasty with adipose-derived stem cells augmentation for osteochondral lesions of the talus.

Background:
Bone marrow stimulation (BMS) is a common surgical intervention in the treatment of small osteochondral lesions of the talus (OLTs). Evidence has shown good clinical outcomes after BMS in ...the short term, but several studies have shown less favorable results at midterm and long-term follow-up because of fibrocartilaginous repair tissue degeneration.
Purpose:
To evaluate the clinical and radiological outcomes of BMS in the treatment of primary OLTs at midterm and long-term follow-up and to investigate reported data in these studies.
Study Design:
Systematic review; Level of evidence, 4.
Methods:
A systematic search of the MEDLINE, Embase, and Cochrane Library databases was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Clinical and radiological outcomes as well as reported data were evaluated.
Results:
A total of 15 studies comprising 853 patients (858 ankles) were included at a weighted mean follow-up time of 71.9 months. There were 9 studies that used the American Orthopaedic Foot & Ankle Society (AOFAS) score, with a weighted mean postoperative score of 89.9. There were 3 studies that measured postoperative magnetic resonance imaging results in the midterm using the MOCART (magnetic resonance observation of cartilage repair tissue) scoring system and showed 48% of patients with complete filling, 74% with complete integration, and 76% with surface damage. There was a complication rate of 3.4% and a reoperation rate of 6.0% after BMS in the midterm.
Conclusion:
This systematic review found good clinical outcomes after BMS at midterm follow-up for primary OLTs. Radiological outcomes showed repair tissue surface damage in the majority of patients, which may be a harbinger for long-term problems. Data were variable, and numerous data were underreported. Further high-quality studies, a validated outcome scoring system, and further radiological reports at midterm follow-up are required to accurately assess the success of BMS in the midterm.
Purpose
The purpose of this study was to determine multiple return to sport rates, long-term clinical outcomes and safety for subtalar arthroscopy for sinus tarsi syndrome.
Methods
Subtalar ...arthroscopies performed for sinus tarsi syndrome between 2013 and 2018 were analyzed. Twenty-two patients were assessed (median age: 28 (IQR 20–40), median follow-up 60 months (IQR 42–76). All patients were active in sports prior to the injury. The primary outcome was the return to pre-injury type of sport rate. Secondary outcomes were time and rate of return to any type of sports, return to performance and to improved performance. Clinical outcomes consisted of Numerous Rating Scale of pain, Foot and Ankle Outcome Score, 36-item Short Form Survey and complications and re-operations.
Results
Fifty-five percent of the patients returned to their preoperative type of sport at a median time of 23 weeks post-operatively (IQR 9.0–49), 95% of the patients returned to any type and level sport at a median time of 12 weeks post-operatively (IQR 4.0–39), 18% returned to their preoperative performance level at a median time of 25 weeks post-operatively (IQR 8.0–46) and 5% returned to improved performance postoperatively at 28 weeks postoperatively (one patient). Median NRS in rest was 1.0 (IQR 0.0–4.0), 2.0 during walking (IQR 0.0–5.3) during walking, 3.0 during running (IQR 1.0–8.0) and 2.0 during stair-climbing (IQR 0.0–4.5). The summarized FAOS score was 62 (IQR 50–90). The median SF-36 PCSS and the MCSS were 46 (IQR 41–54) and 55 (IQR 49–58), respectively. No complications and one re-do subtalar arthroscopy were reported.
Conclusion
Six out of ten patients with sinus tarsi syndrome returned to their pre-injury type of sport after being treated with a subtalar arthroscopy. Subtalar arthroscopy yields effective outcomes at long-term follow-up concerning patient-reported outcome measures in athletic population, with favorable return to sport level, return to sport time, clinical outcomes and safety outcome measures.

Purpose
The primary purpose of this study was to determine the union rate and time for surgical- and non-surgical treatment of stress fractures of the proximal fifth metatarsal (MT5). The secondary ...purpose was to assess the rate of adverse bone healing events (delayed union, non-union, and refractures) as well as the return to sports time and rate.
Methods
A literature search of the EMBASE (Ovid), MEDLINE (PubMed), CINAHL, Web of Science and Google Scholar databases until March 2020 was conducted. Methodological quality was assessed by two independent reviewers using the methodological index for non-randomized studies (MINORS) criteria. The primary outcomes were the union time and rate. Secondary outcomes included the delayed union rate, non-union rate, refracture rate, and return to sport time and rate. A simplified pooling technique was used to analyse the different outcomes (i.e. union rate, time to union, adverse bone healing rates, return to sport rate, and return to sport time) per treatment modality. Additionally, 95% confidence intervals were calculated for the union rate, adverse bone healing rates, and the return to sport rate.
Results
The literature search resulted in 2753 articles, of which thirteen studies were included. A total of 393 fractures, with a pooled mean follow-up of 52.5 months, were assessed. Overall, the methodological quality of the included articles was low. The pooled bone union rate was 87% (95% CI 83–90%) and 56% (95% CI 41–70%) for surgically and non-surgically treated fractures, respectively. The pooled radiological union time was 13.1 weeks for surgical treatment and 20.9 weeks for non-surgical treatment. Surgical treatment resulted in a delayed union rate of 3% (95% CI 1–5%), non-union rate of 4% (95% CI 2–6%) and refracture rate of 7% (95% CI 4–10%). Non-surgical treatment resulted in a delayed union rate of 0% (95% CI 0–8%), a non-union rate of 33% (95% CI 20–47%) and a refracture rate of 12% (95% CI 5–24%), respectively. The return to sport rate (at any level) was 100% for both treatment modalities. Return to pre-injury level of sport time was 14.5 weeks (117 fractures) for surgical treatment and 9.9 weeks (6 fractures) for non-surgical treatment.
Conclusion
Surgical treatment of stress fractures of the proximal fifth metatarsal results in a higher bone union rate and a shorter union time than non-surgical treatment. Additionally, surgical and non-surgical treatment both showed a high return to sport rate (at any level), albeit with limited clinical evidence for non-surgical treatment due to the underreporting of data.
